Abstract:
A surface cleaning and material removal system allows for the cleaning of applied or built-up coatings, debris, and any other matter from a surface. The surface cleaning and removal system includes a housing having a base with a wall extending obliquely therefrom. The base and wall define a cavity which covers the specific portion of the surface to be cleaned at that very moment, although the system is typically on wheels or portably movable so as to clean a very large surface in incremental portions. The system also includes a high-pressure-fluid mechanism for providing a high or ultra high pressure fluid flow against the surface to be cleaned where the mechanism includes either brushes or high pressure jets from which ultra high pressure water flows. In addition, the system includes a vacuum for moving all of the cleaning fluid and coatings, debris and any other matter from the cavity. In at least some of the embodiments, the system includes flexible members, seals, or brushes about the periphery of the walls extending obliquely from the base so as to better seal the cavity while still allowing for movement over the surface to be cleaned. In addition, more than one flexible member, seal or plurality of bristles or brushes may be present thereby defining a circumferential chamber therebetween which is fluidly connected to both the interior cavity and the environment so as to provide a better vacuum for better assuring that all of the cleaning fluids and coatings, debris, and any other matter are removed from the cavity and do not leak therefrom.

CROSS REFERENCE TO RELATED APPLICATIONS 
     This patent application is a divisional application claiming priority from Ser. No. 08/893,729 filed Jul. 11, 1997 U.S. Pat. No. 5,991,968, issuing Nov. 30, 1999, the disclosures of which are incorporated herein by reference. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Technical Field 
     The invention relates to surface cleaning devices for removing dirt, buildup, paint, asbestos, coating materials, or any other buildup or layer on a particular surface by any of a number of methods including cleaning abrading, treating, sanding, grinding, or scraping. More particularly, the invention relates to a high fluid pressure cleaning and removal system for use in removing coatings and buildup from hard, often porous, and generally unpermeable surfaces such as concrete, brick, stone, asphalt, etc. Specifically, the invention is a surface cleaning and removal system using high pressure water with a number of different sized, shaped, and usage housings that include at least one rotating jet of high pressure cleaning water that is vacuumed out of the housing after cleaning by a high suction vacuum where the housing includes one or more rows of annular or peripheral sealing means such as brushes, rubber seals, rubber wipers, or other similar flexible yet sealing instruments. 
     2. Background Information 
     For decades, various devices have been used to attempt to clean generally planar surfaces such as walls, floors, driveways, sidewalks, etc. which are generally flat and hard, yet often porous. Specifically, cleaning has been necessary to remove applied layers or coatings such as paints, etc., as well as unintentional accumulated deposits buildup. For instance, many structures or buildings are built of concrete, brick, stone, block, or other similar materials which are painted and otherwise coated over time. In addition, dirt, pollution, smog and other airborne particles often also deposit thereon. At some point in time, these coatings and deposits may need removed. 
     This removal can be further complicated by additional factors such as asbestos coatings which can only be removed using methods certified by the Federal government due to the hazardous effects of airborne asbestos particles. For this reason, the removed material must be completely contained so as to avoid any airborne implantation of the particles. 
     In the past, sandblasting or other treating of surfaces by impingement of the surface with particulate abrasive material has often been used to remove the above-referenced materials from the above-referenced hard surfaces. However, sandblasting has various disadvantages including the degradation or destruction caused by the abrasive sand or other particulate material to the surface being cleaned. In addition, sand is generally messy and hard to contain. Furthermore, the use of sand or other abrasive materials requires a large supply of such material available at the job site, and therefore requires material transportation cost. A further disadvantage of the use of sand is the difficulty in removing the contaminants from the sand. Finally, often the structure being cleaned must be completely contained such as in a sealed tent or a wrap to assure containment of the sand or other abrasive material, and in the case of hazardous material removal, to assure containment of the loosened and removed hazardous material so that proper disposal is assured. 
     In response, several attempts have been made at alternative surface cleaning devices. For instance, devices using cleaning liquids directed against the surface have also been suggested, such as that in U.S. Pat. No. 4,895,179. The cleaning apparatus in &#39;179 patent is for cleaning a generally planar and horizontal surface. The device includes a jet of cleaning liquid directed against the surface. Other liquid cleaning devices have also been invented. 
     The present technology of liquid cleaning devices has several disadvantages. First, the pressure and acceleration of the liquid is often merely sufficient to rinse away loose dirt and other buildup while not being sufficient to remove applied coatings. Second, many of the current cleaning devices do not provide a sufficient surface cleaning area to make use of the device feasible on buildings, driveways, etc., which include very large surface areas. Third, the prior art fluid cleaning devices have proved inefficient or completely ineffective at containing the cleaning fluid as well as the debris created therefrom, whereby such containment is critical for a number of reasons including overall cleanliness of the project and overall containment of any hazardous materials found in the removed coatings and buildup. Furthermore, all of the current fluid cleaning devices do not provide for any ability to clean nonplanar and often nonhorizontal surfaces. Similarly, corners and edges and other tight spots are also not addressed by the current fluid cleaning devices. 
     Clearly, an improvement is needed in the cleaning device area to overcome some or all of the disadvantages and problems addressed above.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     A first embodiment of a surface cleaning and material removal system of the present invention is generally shown in FIGS. 1-4 and indicated as  1 . The surface cleaning and material removal system  1  as shown in this embodiment as well as the others disclosed below is used for cleaning surfaces so as to dislodge and remove any coatings or other materials that have been applied to or built up on that surface but are now desired to be removed. Specifically, the surface cleaning and material removal system  1  is used for removing coatings and buildup from hard, often porous, and generally unpermeable surfaces such as but not limited to concrete, masonry, brick, block, stone, asphalt, etc. It is often desirable to clean these and other surfaces of dirt, paint, asbestos, water proofing, tar, coating materials, or other buildup or layered coatings either intentionally deposited or incidentally built-up on the surface to be cleaned but no longer needed or desired thereon. 
     In the first embodiment as is shown in FIGS. 1-4, the surface cleaning and material removal system  1  includes a housing  2 , a high-pressure-fluid cleaning mechanism  3 , and a vacuum mechanism  4 . In addition, in large-sized versions of the system (the version in FIG. 1 is of a large size), the surface cleaning and material removal system also includes a handle mechanism  5  and wheels, namely one or both fixed wheels  6  and pivotable wheels  7 . The wheels ride on a surface  8  to be cleaned. 
     The first embodiment of the housing  2  as best shown in full in FIGS. 1-3 and in part in FIG. 4 includes a plate  10  which is in effect a deck, base or platform from which at least one wall  11  obliquely extends. The plate  10  and wall  11  define a cavity  12  with an open area  13  facing the surface  8  to be cleaned. In FIGS. 1-4, the plate  11  is of an octagonal shape and has eight wall parts  11 A,  11 B,  11 C,  11 D,  11 E,  11 F,  11 G, and  11 H (best shown in FIG. 2) extending outward from one side of the plate  10  to in a perpendicular manner to the plate  10 . The plate  10  however could be of any of a number of other shapes including but not limited to round, triangular, square, rectangular, pentagonal, hexagonal, heptagonal, or decagonal and correspondingly the wall  11  would have an equivalent number of wall parts, that is one, three, four, four, five, six, seven, or ten, respectively. Also, the wall parts defining the wall(s) may be either planar such as is best shown in FIG. 2 or non-planar such as where the plate  10  is round and thus the wall  11  is curved in an annular manner. 
     A hollow member  15  is attached to the outer surface of the wall  11  along the outermost (furthest away from the plate  10 ) portion of the wall from the plate. The hollow member  15  extends around the entire perimeter of the wall  11  thereby defining one endless fluid chamber around the perimeter of the housing  2 . The hollow member  15  in the embodiment shown in FIGS. 1-4 is a plurality of pieces  15 A,  15 B,  15 C,  15 D,  15 E,  15 F,  15 G, and  15 H attached together in a similar manner to the wall parts  11 A- 11 H. (As previously discussed, the member  15  could be one piece or any number of pieces corresponding to one or any number of walls.) The hollow member  15  in the embodiment shown in FIGS. 1-4 and  4 A- 4 B is designed such that the cross section of the member is of a rectangular or square sectional area defined by a front flat surface  16 , a top flat surface  17 , a back flat surface  18 , and a bottom flat surface  19  as is best shown in FIGS.  4 , 4 A, and  4 B. As also shown in FIGS. 4,  4 A, and  4 B, the hollow member  15  also includes a first plurality of elongated slots  20  (breather slots) in the front flat surface  16  and a second plurality of elongated slots  21  (fluid flow slots) in the bottom flat surface  19 . 
     In the preferred embodiment as shown, the hollow member  15 A- 15 G is of an upright rectangular sectional shape along each of the wall parts  11 A- 11 G and includes slots  20  and  21  substantially equally dispersed therealong, while the hollow member  15 H along wall part  11 H (the backmost wall area) is enlarged with respect to the other portions. Specifically, the hollow member  15 H along wall part  11 H is of a substantially larger width orientation as is shown in FIG. 4 such that the sectional shape is a lying-down rectangle. In addition, the hollow member  15 H along wall part  11 H does not include a standard slot or slots  20  in the outer surface, but instead includes an inner slot  9  for vacuuming purposes. (Hollow members adjacent to hollow member  15 H may also have a reduced number or complete elimination of the slots  20  as needed to properly assure a vacuum). Furthermore, the hollow member  15 H along wall part  11 H has enlarged slot(s)  21  in comparison to those in the other wall parts  11 A- 11 G and thus identified as  21 H. 
     The hollow member  15 H along the wall part  11 H has an open top  22  rather than a top flat surface  17 . The open top  22  is connected to a funnel  23  in the vacuum mechanism  4 . The vacuum mechanism as shown in FIGS. 1-4 also includes a hose  24  which connects to a vacuum supply (not shown). 
     Also connected to the housing  2 , on the opposite or inner surface of wall  11  as the hollow member  15 , is a support plate  25  that extends around the entire inner perimeter of the wall  11  about its bottommost portion. In the embodiment shown in FIGS. 1-4, the support plate is actually a plurality of (in this case eight) support plate portions  25 A,  25 B,  25 C,  25 D,  25 E,  25 F,  25 G, and  25 H corresponding to each of the eight wall parts  11 A- 11 H. Each of the support plate portions  25 A- 25 H includes a first plate  26 , a second plate  27 , and a plurality of pegs  28  for spacing the plates  26  and  27  apart from the wall  11  of the housing  2  as best shown in FIG. 2. A screw, rivet or other fastener  29  extends through plates  26  and  27 , and one of the pegs  28  to secure the support plate  25  to the wall  11  along the bottommost, inner edge of the wall. 
     An inner sealing member  30  is supported between the plates  26  and  27  by the fasteners  29 . Sealing member  30  extends outward from the support plates  25  in an opposite direction as the wall  11  thereby defining an extension  12 A to cavity  12 . Sealing member  30  may be a flexible rubber plate, a bristle brush, a seal of any type, or any other member capable of providing a flexible body that follows the contours of surface  8  while sufficiently providing sealing to support the vacuum functions of the cavity during cleaning as described below in more detail. In the first embodiment, as shown in FIGS. 1-4, sealing member  30  is actually  8  sealing portions aligned end to end in a touching relationship to form an octagon. 
     Housing  2  also includes a second or outer sealing member  31 . The outer sealing member  31  is attached to the outer surface of the hollow member  15  by an elongated plate  32  that sandwiches the sealing member against the front or outer flat surface  16  of the hollow member  15 . A plurality of screws, rivets or other fasteners  33  affix the outer sealing member  31  to the hollow member  15 . The outer sealing member  31  is of a substantially identical construction to the inner sealing member  30  in that it may be a flexible rubber plate, a bristle brush, a seal of any type, or any other member capable of providing a flexible body that follows the contours of surface  8  while sufficiently providing sealing to support the vacuum functions of the cavity during cleaning as described below in more detail. Similar to sealing member  30 , sealing member  31  in the first embodiment is actually eight sealing portions aligned end to end in a touching relationship to form an octagon larger than and surrounding the octagon of the inner sealing members  30 . In addition, the inner and outer sealing members may be of differing types, that is one may be a flexible rubber plate while the other is a bristle brush. 
     As a result of the inner and outer sealing members  30  and  31 , an annular chamber  12 B is defined which in effect expands the area of the extension  12 A of the cavity  12 . A tortuous path  35  connects the extension area  12 A with the cavity  12  with the annular chamber  12 B with the hollow member  15 . The path  35  extends through a gap  36  as defined between the pegs  28  and through the slots  21  such that fluid and debris in cavity  12  and extension  12 A can be vacuumed or suctioned into vacuum hose  24 , and any leakage that leaks under inner sealing member  30  into annular chamber  12 B is also vacuumed or suctioned into vacuum hose  24 . The fluid and debris passes through the gap  36  into the annular chamber  12 B where it is suctioned through the slots  21  into the hollow member  15 . All of the fluid and debris in the hollow member  15  is suctioned around to the larger section of the hollow member along the wall part  11 H where the fluid and debris passes through open top  22  and funnel  23  toward a collection mechanism (not shown) in the vacuum mechanism  4 . 
     Also attached to the housing  2  of the embodiment shown in FIGS. 1-4 are the wheels  6  and  7 . The fixed wheels  6 , as best shown in FIGS. 1-2 and  4 , are each mounted to the housing  2  on a rigid plate  40  from which a pair of axle supports  41  extend. Each wheel  42  includes an axle  43  rotatably affixed between and within the respective axle supports  41 . As to the pivotable wheels  7 , also best shown in FIGS. 1-2 and  4 , each pivotable wheel is mounted to the housing  2  on a bracket  45  with a hole  46  therein. A threaded pin  47  extends through and out of the hole where the pin terminates in a fork  48  attached via a bearing or other pivot connection  49 . A wheel  50  with an axis  51  is supported between the fork  48  and is pivotable about the bearing  49 . In the embodiment shown, a pair of fixed wheels  6  are used on the rear of the housing while a pair of pivotable wheels  7  are used on the front of the housing. 
     Further attached to the embodiment shown in FIGS. 1-4 is a handle mechanism  5 . Handle mechanism  5  includes a handle bar  52  extending outward from a handle bracket  53  on the housing. Approximate the outer end of the handle bar  52  is a control plate  54  for supporting switches, levers, and other controls as needed to operate the high-pressure-fluid cleaning and removal system  1 . 
     The first embodiment of the housing  2  further includes a hole  58  in the plate  10 . As shown in FIG. 4, the high-pressure-fluid cleaning mechanism  3  partially extends through this hole  58 . This cleaning mechanism  3  includes a washing head  60 , high pressure water system  61 , and a rotation providing mechanism  62  all of which interact to provide high or ultra high pressure fluid such as water for cleaning the surface  8  to be cleaned. 
     As shown in FIG. 4, the first embodiment of washing head  60  includes a rotatable main feed  65 , a “T” or other branching fitting  66 , one or more branch feeds  67 , and a plurality of jets  68  on each branch feed. 
     As also shown in FIG. 4, the first embodiment of the high pressure water system  61  includes a mounting bracket  70 , a gear box  71 , a gear box drive shaft  72 , a swivel within a swivel housing  74 , a swivel nut  75 , a hose fitting  76 , an ultra high pressure water hose  77 , and an ultra high pressure water supply (remotely located and not shown). Mounting bracket  70  is mounted on the top surface of plate  10  over hole  58 . Gear box  71  is mounted within mounting bracket  70 . Gear box drive shaft  72  extends through the gear box  71  and is rotatably driven by the gear box  71 . Attached to one end of the drive shaft  72  is the washing head  60  and attached to the other end of the drive shaft  72  is the swivel housing  74  and the swivel nut  75 . The swivel housing  74  and swivel nut  75  remain stationary while the drive shaft  72  rotates as the swivel nut provides a connection for the hose fitting  76  on the end of the water hose  77  to the drive shaft  72  which is hollow with a fluid passage therein to the washing head  60 . The swivel housing  74  and swivel nut  75  allow the drive shaft to rotate from within while remaining stationary, and provide a fluid connection of the stationary water hose  77  to the rotatable drive shaft  72 . 
     As further shown in FIG. 4, the first embodiment of the rotation providing mechanism  62  includes a main air supply hose  82 , a trigger or actuation/control lever  83 , a motor air supply hose  86 , an air motor  87 , and a muffler  88 . The air motor  87  is attached to the gear box  71  for providing air for driving the drive shaft  72 . The air supply hose  82  connects the lever  83  to a remote pressurized air supply (not shown), where the lever  83  in this embodiment is attached to the handle  5 . Lever  83  and/or any other controls on the handle  5 , control air and/or water flow through air hose  86  and water hose  77 . When the lever  83  is actuated, the air is allowed to pass from hose  82  through the passage to hose  86  which is connected to air motor  87 . The air then drives the drive shaft  72 . 
     In operation, system  1  is positioned such that open area  13  is over the surface  8  to be cleaned. Lever  83  is moved thereby allowing pressurized air from hose  82  into hose  86 . The pressurized air drives the air motor  87  which in turn rotates the drive shaft  72  of the water system  61  causing the washing head  60  to rotate. Simultaneously with the movement of the lever  83 , ultra high pressure water from a remote water supply is allowed to pass into water hose  77  whereby the water travels to the washing head  60  via the hollow interiors of the swivel housing  74 , swivel nut  75 , and the drive shaft  72 . The ultra high pressure water is dispersed from the washing head  60  via the jets  68 . The water pressure exiting the jets is maintained at between a few thousand psi and 100,000 psi depending upon the surface material and the types of coating and debris thereon, although for many applications it has been found that 30,000-40,000 psi is optimal. 
     The coatings and debris are in effect power washed from the surface by the ultra high pressure water. The coatings and debris (material), and the water are substantially maintained within the cavity  12  and extension  12 A by the inner sealing member  30 . However, to assure complete containment, sealing member  31  further assures that any material that escapes from the cavity  12  and extension  12 A is held within the annular chamber  12 B as defined between the annular sealing members  30  and  31 . A vacuum is supplied to the cavity  12 , extension  12 A, and annular chamber  12 B via open top  22  and funnel  23  whereby the material is vacuumed from cavity  12  and extension  12 A to a remote vacuum. The material follows the tortuous path  35  from cavity  12  and extension  12 A either (A) to the back wall  11 H of cavity  12  and through inner slot  9  to hollow member  15 H and funnel  23  whereby the material is suctioned out to a remote collection container via vacuum hose  24 , or (B) over support plate  25  and through the space or gap  36  between pegs  28  to the annular chamber  12 B and hollow member  15  (via slots  20 ) where the material follows the annular chamber and/or hollow member around the housing to the larger hollow member  15 H, where the material continues to be suctioned out to a remote collection container via funnel  23  and vacuum hose  24 . 
     During operation of the vacuum, the suctioning or vacuum force may be of any volume capable of supplying sufficient vacuum to assure no leakage under the sealing members  30  and  31 . In one operational environment it has been found that between 1,000 and 10,000 cfm was adequate, with between 4,000 and 6,000 cfm being optimal. The slots  21  are supplied to allow a certain amount of ambient air into the system to replace air, water and debris suctioned out and to assist the vacuum process by providing an aspirating behavior as is well known in aspirators for inflating devices such as air slides and rafts. 
     The wheels  6  and  7  allow the housing  2  to be moved around to remove coatings and debris over a large area. The handle  5  allows a user to push the housing  2 . Specifically, the unit is pushed or pulled in a systematic manner such that a large surface area is cleaned, in effect a row or pass at a time, until all of the adjacently defined rows cover the entire large surface area. After completion, the material collected in the remote location such as a tank or truck is filtered such that the water is removed from the coatings, debris, dirt, hazardous materials, etc. whereby these materials are then properly disposed. The net result is that the housing  2  with its cavity  12  and sealing members  30  and  31  therearound with a vacuum supplied thereto alleviate the need for cleanup and the need for prior preparation of the area such as tenting as is well known in the asbestos cleanup area. All of the removed material is collected by the system for disposal; and this all includes even the ultra high pressure water used to remove the coatings, build-up and debris. 
     A modified version of system  1  is shown in FIGS. 5-7 in which a pair of cleaning mechanisms  3  rather than one are installed within the housing  2 . Specifically, two holes  58  are found in the housing, and two washing heads  60 , two high pressure water systems  61 , and two rotation providing mechanisms  62  clean the surface  8 . Otherwise, the parts of this second embodiment are identical to those of the first embodiment. 
     Another modified version of system  1  is shown in FIG. 8 in which a pair of washing heads  60  and a pair of high pressure water systems  61  are coupled to one rotation providing mechanism  62 . Otherwise, the parts of this third embodiment are identical to those of the first and second embodiments. 
     One of the systems  1  from FIGS. 1-8 (specifically from FIG. 5) is shown in FIGS. 9-11 attachable to a track or rail system  90  so that the large housing  2  can be used vertically rather than horizontally or on a slope as preferred with the embodiments of FIGS. 1-8. This allows for the cleaning of walls or exterior surfaces on buildings for example. 
     The track or rail system  90  includes a pair of spaced apart and parallel tracks  91  in which the system  1  rides. The housing  2  includes a pair of flanges  92  extending from the outer surface, and preferably the plate  10 , of the housing  2  about opposite sides thereof. The flanges  92  have slide mechanisms  93  thereon for interacting with the tracks  91  so as to allow the housing  2  to move along the tracks in a manner in which the housing is pinned in between the tracks and against the surface  8  to be cleaned. 
     Slide mechanisms  93  may be any type of ball bearing, bearings, wheels, slides, casters, smooth surface, C-channel, etc. which allows the housing  2  to slide over or along the tracks  91 . Similarly, the tracks  91  may be any type of elongated guide which allows sliding of the housing  2  and guides or holds the housing also, such as a rail, track, channel, C-channel, grooved or slotted structure, etc. It is intended that the tracks  91  may be affixed to the surface to be cleaned in any known manner including using fasteners or banding the tracks around the entire structure. 
     In one version, the tracks  91  are C-channels  94  with an elongated slot  95  therein of a lesser width than the hollow interior of the channel, and the slide mechanism  93  are two pair of wheels  95  and  96 , each pair including an inner wheel (not shown) which rides and is slidable within the C-channel  94  but not removable through the slot  95  of the C-channel thereby holding the housing  2  adjacent to the track  91 , and an outer wheel  97  (FIG. 11) which rides on the outside of the C-channel  94  over the open slot  95  therein. Each pair of wheels is affixed to the flange  92 . 
     A pull cable  98  is provided for moving the housing  2  up and down within the tracks  91 . Preferably, this pull cable  98  is attached to an actuator such as a winch or other cable motion device. 
     A second embodiment is shown in FIGS. 12-15 which is an intermediate size  15  (the first embodiment being of a large size) and lighter-weight hand-held unit in comparison to the larger push and/or pull units of FIGS. 1-11. Specifically, the second embodiment is shown in FIGS. 12-15 and generally indicated as  101 . The housing, now indicated as  102 , is of a substantially identical design, configuration, and shape, but is of a smaller size than the housing  2  in FIGS. 1-11. Each of the parts of system  101  that is identical of substantially identical to those of system  1  as previously described is similarly numbered as in system  1 . (Each of these elements will not be re-introduced unless differences need to be pointed out between the new element and the previously introduced element.) However, one difference is that on intermediate sized or smaller units, the slots  22  are not necessary as the surface area to be vacuumed is such that the additional air is not needed. 
     As to the cleaning mechanism, now indicated as  103 , and particularly its main features of the washing head, high pressure water system, and rotation providing mechanism, the handle  5  is removed and a trigger assembly replaces it in which the washing head, high pressure water system and rotation providing system are all attached on the plate  10  of the housing  102  as is shown in FIGS. 12-15. Specifically, the washing head, which is indicated as  160 , is of a smaller dimension but is still rotatably mounted within the cavity  12 . Basically, washing head  160  includes a rotatable main feed  65 , a “T” or other branching fitting  66 , one or more branch feeds  67 , and a plurality of jets  68  on each branch feed just as the larger washing head does so the main difference is overall length. However, the high pressure water system and rotation providing system are substantially different and are therefore numbered accordingly. 
     The high pressure water system of the second embodiment is indicated as  161  and the rotation providing system of the second embodiment is indicated as  162 . The high pressure water system  161  includes a mounting bracket  170 , a gear box  171 , a gear box drive shaft  172 , a swivel within a swivel housing  174 , a swivel nut  175 , a hose fitting  176 , an ultra high pressure water hose  177 , and an ultra high pressure water supply (remotely located and not shown). Mounting bracket  170  is mounted on the top surface of plate  10  over hole  58 . Gear box  171  is mounted within mounting bracket  170 . Gear box drive shaft  172  extends through the gear box  171  and is rotatably driven by the gear box  171 . Attached to one end of the drive shaft  172  is the washing head  160  and attached to the other end of the drive shaft  172  is the swivel housing  174  and the swivel nut  175 . The swivel housing  174  and swivel nut  175  remain stationary while the drive shaft  172  rotates as the swivel nut provides a connection for the hose fitting  176  on the end of the water hose  177  to the drive shaft  172  which is hollow with a fluid passage therein to the washing head  160 . The swivel housing  174  and swivel nut  175  allow the drive shaft to rotate from within while remaining stationary, and provide a fluid connection of the stationary water hose  177  to the rotatable drive shaft  172 . 
     The rotation providing mechanism  162  includes a main air supply hose  182 , a first trigger assembly  183 , a second trigger assembly  184 , a safety handle and second trigger base  185 , a trigger connection hose  186 , an air motor  187 , a muffler  188 , and an air return hose  189 . The air motor  187  is attached to the gear box  171  for providing air for driving the drive shaft  172 . The air supply hose  182  connects the remote pressurized air supply to the first trigger assembly  183  while the trigger connection hose  186  connects to the first trigger assembly to the second trigger assembly  184  and the air return hose  189  connects back to the remote pressurized air supply thereby completing the fluid circuit. Each trigger assembly  183  and  184  includes a trigger body  198  and a trigger  199 . The second trigger assembly also includes a handle hole  197 . The triggers control the air and water flow through air hoses  182 , 186  and  189  and water hose  177 . When both triggers  199  are actuated, the air is allowed to pass through the hoses thereby actuating the air motor  187 . The air then drives the drive shaft  172 . In addition, water is allowed through the water hose  177  into the swivel housing and nut  174  and  175  whereby the water passes into the rotating drive shaft  172  and washing head  160  for high pressure distribution via jets on the head. The double triggers serve as a safety feature since both triggers must be actuated to activate the system. 
     Furthermore, the addition of the air return hose  189  alters the system such that instead of simultaneous actuation of the rotation providing mechanism and the high pressure water system as occurs in the first-fourth embodiments (FIGS.  1 - 11 ), this fifth embodiment incorporates a sequential system where the rotation providing mechanism is actuated by the first trigger, but the high pressure water system is not activated until the second trigger is actuated thereby providing pressurized fluid back through the air return hose  189  to activate the high pressure water system. 
     A modified version is shown in FIG. 14A where the sealing members  30  and  31  are replaced by brushes  230 . Also, the tortuous path  35  and all of its components including support plate  25 , hollow member  15 , etc. are replaced merely by an attachment plate  125  that affixes the brushes  230  to the outermost edge of the wall  11 . 
     A modified version is shown in FIGS. 16-19 as system  201  which incorporates the size of the system  101  with the brushes  230  of FIG.  14 A and lack of a tortuous path of the system  101  with a housing shape change from an octagon to a cylinder. Otherwise, system  201  is substantially identical to system  101  and is thus identically numbered. It is contemplated as described above that the housing could be shaped of any polygonal shape, a round shape, an oval shape or any non uniform shape so long as the cavity is capable of housing a washing head and being sealable so that water and material does not escape the cavity. 
     It is further contemplated that the outermost surface of the system, which is generally the sealing surface that rides along the surface to be cleaned, need not be planar since many non-planar areas exist in which cleaning is required such as inner and outer corners of both a 90° or other acute or obtuse angle. Examples of a few such embodiments are shown in FIGS. 20-27. 
     A third embodiment of the high pressure cleaning and removal system is shown in FIGS. 20-23 and generally indicated as  301 . This embodiment is a small hand-held unit for cleaning outer corners of approximately a 90° angle. The size of this unit is smaller than both the large and intermediate sized units described above and it lacks the tortuous path and double sealing members as used with the above units since these are not needed to assure no leakage and proper vacuum. The high pressure water system  161  and the rotation providing mechanism  162  of this third embodiment are identical or substantially identical to that of the second embodiment as described in detail above (and are thus similarly numbered to the second embodiment as shown in FIGS. 12-16. The housing, indicated as  302 , of this third embodiment is smaller than the above described embodiments and is of a square shape, and lacks the tortuous path and double sealing member construction of the larger designs, but is otherwise similar and thus similarly numbered. The sealing member is a brush  330  extending around the square perimeter of the housing (although it is contemplated that it could be a rubber seal or other sealing member). Specifically, the sealing member is a set of brushes  330 A,  330 B,  330 C and  330 D, each fastened to the housing. 
     In the embodiment as shown, the housing  302  includes mounting plates or channels  390  in which the brushes  330  are held. These mounting plates  390  are affixed to the housing  302  using fasteners  391 . The housing  302  is designed such that the sides  392  and  394  extend outward further than the front  393  and back  395  as is shown in FIG.  20 . This allows shorter bristles to be used which are more rigid. As to the front  393  and back  395  as best shown in FIG. 21, the bristles are cut in an inverted V-shape  396  to account for the outer corner to be cleaned. The housing can either have a similar V-shape or it may have a square edge that does not extend outward as far as the sides so as to account for the valley in the V. 
     A fourth embodiment of the high pressure cleaning and removal system  401  is shown in FIGS. 24-25. This embodiment is a small hand-held unit for cleaning inner corners of approximately a 90° angle. This is also a small unit without a tortuous path or double sealing arrangement as it is not needed to assure no leakage and proper vacuum. The high pressure water system  161  and the rotation providing mechanism  162  of this fourth embodiment are identical or substantially identical to that of the second and third embodiments as described in detail above. The housing  402  of this fourth embodiment is of a similar size to the third embodiment which is smaller than the above described first and second embodiments and is of a square shape, and lacks the tortuous path and double sealing member construction of the larger designs. The sealing member is a brush  430  extending around the square perimeter of the housing. Specifically, the sealing member is a set of brushes  430 A,  430 B,  430 C, and  430 D, each fastened to the housing. 
     In the embodiment as shown, the housing  402  includes mounting plates or channels  490  in which the brushes  430  are held. These mounting plates  490  are affixed to the housing  402  using fasteners  491 . The housing  402  is designed such that the front  492  and back  494  extend outward further than the sides  493  and  495  as is shown in FIG. 25 in a triangular or V-shaped manner  496 . This allows shorter bristles to be used which are more rigid yet properly define the inner corner shape needed. As to the sides  493  and  495  as best shown in FIG. 24, the bristles are also short but follow a straight line. 
     A fifth embodiment of the high pressure cleaning and removal system is shown in FIGS. 26-27 and indicated generally as  501 . This is the smallest of the embodiments. The housing  502  is smaller than all of the above described embodiments. In this version, only one or the first trigger  183  is used (thus the safety feature of two triggers is not used). Also, the housing  502  is basically a box construction without the tortuous path, slots, and double sealing members of the larger designs. The housing  502  does include a handle  505  as a second holding device to replace the removed second trigger, where the handle  505  extends transversely out of the side of the housing  502  as best shown in FIG.  27 . 
     A modified version of the high pressure cleaning and removal system is shown in FIGS. 28-29 as indicated generally as  601 . This embodiment selectively incorporates either or both two pair of wheels attached to the housing  602  of the fixed type  7  (although one or both sets could alternatively be of the pivotable type  6 ) and/or a modified washing head  660 . The modified washing head  660  is a circular bristle brush that is rotatable by the drive shaft  72  in the same manner as the above described washing head. In this embodiment, the brush  660  is rotated at a high speed such that the coating and build-up is in effect scrubbed off. Water may optionally be provided under low or high pressure, where the high or ultra high pressure water assists in the removal process, while low pressure water is merely used as a conduit in which the material removed is entrained or otherwise mixed for easier vacuum removal. 
     A sixth embodiment of the high pressure cleaning and removal system is shown in FIGS. 30-31 and generally indicated as  701 . This embodiment is designed to clean corners along the floor where a wall and the floor meet. Rather than use the smaller above described corner units, the seventh embodiment was designed. Preferably, the housing  702  is of a square design so as to have a side area  709  for cleaning the wall while the cavity  712  on the bottom cleans the floor. The housing unit of this embodiment has one open side at side area  709  and three side walls  702 A,  702 B and  702 C. The open area  712  on the bottom and this open side  709  each have a sealing member  730  around its periphery. The sealing member  730  on the open area  712  is preferably a rubber seal while the sealing member  709  on the open side is a brush. 
     In this embodiment, the housing  702  also includes a pivotable handle assembly  705  so as to allow the system to be pushed in either direction. The handle assembly  705  shown in a first position in FIG. 31 while in a second position in shadow as  705 A with an arrow showing the selective pivoting. 
     A modified high pressure cleaning and removal system is shown in FIGS. 32-34 and generally indicated as a combination of system  1  and system  701 . This combination combines a large system such as that shown in FIGS. 1-11 with the sixth embodiment as shown in FIGS. 30-31. Specifically, an attachment frame  790  is attached to the plate  10  of the large system  1  for adjustably carrying a second smaller system  701  as is best shown in FIGS. 32-33. The frame  790  includes a mounting bar  791  on the second system  701  with a clamp  792  at its outer end. The frame further includes a slide bar  793  connected to the housing  2  of the first system  1  and a support bar  794  supporting the slide bar by extending from its outermost point to the housing  2  of the first system  1 . The clamp is selectively engageable with the slide bar whereby the second system  701  is slidable up and down so as to allow for corner cleaning as well as cleaning the area above the floor that is often missed by the tracked wall unit as described in the version as shown in FIGS. 9-11. The drawings show the high-pressure-fluid cleaning mechanism  3  and the vacuum mechanism  4  of the system  1  removed as this is an option although such components may also be present. 
     A seventh embodiment of the high pressure cleaning and removal system is shown in FIGS. 35-37 and indicated generally as  801 . This embodiment is for the cleaning of ceilings or other overhead surfaces. The system  801  includes a standard high pressure cleaning and removal system such as the one disclosed in FIGS. 1-11 where this system  1  is attached to a cart in a pivotable manner. Specifically, a cart  890  with wheels  891  has a pair of upright supports  892  extending outward from a base  893 . At the uppermost ends of the upright supports  892  are swivels  894  which are connected to actuators  895  extending rigidly outward from housing  2  of system  1 . The swivels allow the entire system  1  with actuators  895  to be pivoted about the swivels  894  in a 360 degree manner. Such pivoting is shown when FIGS. 35 and 36 are compared and further shown by arrows  896  in FIG.  36 . 
     Each of the swivels  894  is rigidly fastened to the uppermost ends of upright supports  892  while including a bearing or other swivel mechanism  896  and a connector  897  selectively attachable to one of the actuators  895 . 
     Furthermore, cranks  898  are provided on actuators  895  for actuating or otherwise moving housing  2  and system  1  by opening up each of actuators  895  as is shown in FIG.  37 . This allows the system  1  to be elevated towards and into contact with the ceiling or other overhead surface to be cleaned. 
     The purpose of the embodiment shown in FIGS. 35 and 36 is that ceilings can be cleaned with a stable system, while allowing for the system to be collapsed or otherwise positioned in a reduced height manner so as to be able to move the entire system through doorways and other limited height areas. Specifically, the system as shown in FIG. 35 is capable of being moved through a doorway while the system as shown in FIGS. 36 and 37 is being opened up and prepared for ceiling surface cleaning. 
     In each of the above embodiments, a vacuum mechanism is used. The vacuum is generally remotely positioned away from the system. Therefore, a vacuum hose such as hose  24  is used to connect the vacuum supply (remotely located) with the system such as through funnel  23 . So as to provide for an easy means of disconnecting the vacuum hose  24  from the system, a coupling  900  was designed as is shown in FIGS. 38 and 39. 
     The coupling  900  includes a sleeve  901 , a pair of seals  902  and  903 , and a special coupler  904  attached to the system such as system  1  as is shown in the Figures. Specifically, the special coupler  904  is attached at the end of the funnel  23  in system  1 . Coupler  904  includes a pair of grooves  905  and  906  in which seals  902  and  903  are seated. Sleeve  901  is then fastened to hose  24  in a permanent manner. Sleeve  901  is then slid over coupler  904  such that a tight seal is formed by seals  902  and  903 . Sleeve  901  is then held on coupler  904  by a pin  907  which is inserted through a hole  908  in sleeve  901 . The pin engages a groove  909  in coupler  904  and allows for rotation of hose  24  and sleeve  901  about coupler  904  but prohibits axial withdraw therefrom. As a result, the hose  24  may rotate as needed during use but is not accidentally removable when pulled too hard. However, this design also allows for easy removal of the hose  24  when needed by merely removing pin  907  from hole  908  thereby disengaging pin  907  from groove  909 . Specifically, pin  907  seats within groove  909  in a tangential manner. 
     Accordingly, the improved high pressure cleaning and removal system is simplified, provides an effective, safe, inexpensive, and efficient device which achieves all the enumerated objectives, provides for eliminating difficulties encountered with prior devices, and solves problems and obtains new results in the art. 
     In the foregoing description, certain terms have been used for brevity, clearness and understanding; but no unnecessary limitations are to be implied therefrom beyond the requirement of the prior art, because such terms are used for descriptive purposes and are intended to be broadly construed. 
     Moreover, the description and illustration of the invention is by way of example, and the scope of the invention is not limited to the exact details shown or described. 
     Having now described the features, discoveries and principles of the invention, the manner in which the improved high pressure cleaning and removal system is constructed and used, the characteristics of the construction, and the advantageous, new and useful results obtained; the new and useful structures, devices, elements, arrangements, parts and combinations, are set forth in the appended claims.
