     FIELD OF THE INVENTION  
       [0002]     The present invention generally relates to the field of hydraulic devices such as pressure washers, water jets, and the like that are capable of delivering a fluid from a supply source and discharging it under pressure, and more particularly, to apparatus, systems, and methods of utilizing these hydraulic devices.  
       BACKGROUND OF THE INVENTION  
       [0003]     The use of hydraulic fluids, i.e., water, oils, air, for devices which create and use highly pressurized streams of fluid to accomplish a task is commonplace. For instance, a pressure washer or water jet deliver a highly pressurized fluid stream to a surface to be cleaned, stripped, or prepared for treatment. Alternatively, these devices may deliver a highly pressurized fluid stream to lifting mechanisms, digging mechanisms, or for recreational purposes. As such, hydraulic devices, such as pressure washers and water jets, are produced in numerous design configurations and can be used to perform a variety of tasks whether in a home, commercial, or industrial setting.  
         [0004]     These devices are powered by a power source which drives the pump to which a directional controlling device, such as a spray wand of gun, may be coupled via a length of hose. Typically, the power source is either an electric motor or combustion engine. Whether the high pressure device is a portable device or a stationary device will determine the size of the engine and therefore the power of the pump to pressurize the fluid stream. In the industrial and/or commercial settings the devices are generally stationary which accommodates larger engine and pump size, that have the ability to create a larger stream, i.e., greater capacity, higher pressure, of pressurized fluid. For example, car washes, hydraulic lifts, and the like, will employ stationary hydraulic devices to move large volumes of water or overcome significant weight resistance.  
         [0005]     Unfortunately, most of these devices, such as the pressure washers and water jets, have been limited in their application. Therefore, it would be desirable to provide hydraulic devices which may be used in a wider variety of settings to accomplish a greater number of tasks.  
       SUMMARY OF THE INVENTION  
       [0006]     Accordingly the present invention provides hydraulic devices, such as pressure washers and water jets, which allow an operator to accomplish a greater number of tasks in various settings.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0029]     Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. It is to be understood that the various embodiments shown may be configured as closed or open systems. In an open system, the pump produces a pressurized fluid stream which is expelled through various devices, such as a gun. The expelled pressurized fluid stream is utilized in the performance of a task, but the fluid utilized is lost. In a closed system, the pump produces a pressurized fluid stream which is expelled for use in the performance of a task, as described above. However, the expelled fluid is recaptured into a storage facility, such as a reservoir, which may then be re-used by the pump in providing the pressurized fluid stream. In alternative embodiments, the fluid may be directed into a secondary device for use in the performance of a task and then recaptured from the secondary device after completion of the task.  
         [0030]     Referring generally now to  FIGS. 1 through 3 , exemplary embodiments of cleaning systems of the present invention are shown. In  FIG. 1 a  hydraulic pump system is shown enabled as a high pressure pipe cleaning system. The pipe cleaning system uses a high pressure fluid, such as water, to provide a tool which may be used to clean out confined areas. The confined areas may include pipes which have been clogged with debris. In one embodiment, the pipe cleaning system may employ a high pressure nozzle which may be fed into and/or down the pipe. The nozzle directs the stream of high pressure fluid towards the blockage, breaking the blockage apart and unclogging the pipe. In an alternative embodiment, the roto-rooter system may employ a high pressure blade attachment. The high pressure blade attachment may be fed into and/or down the pipe. The fluid fed into the high pressure blade attachment may impart angular momentum to the blade, the spinning blade may engage with the blockage and due to its high spin rate and cutting surfaces, cut the blockage apart and unclog the pipe.  
         [0031]     The pipe cleaning system employs a power source, such as an electric engine, to provide power to a pump which drives the fluid through the system. Other components may include hoses, pipes, tubes, or other fluid delivery devices which may couple with the pump to deliver the fluid. Further, the fluid delivery devices may couple with the nozzle and high pressure blade attachment, thereby delivering the fluid to these devices. The high pressure blade attachment may be configured in a variety of ways, such as with a sheathed blade which extends upon engagement with the blockage, and may be of various shapes and sizes as contemplated by one of ordinary skill in the art. It is further contemplated that the pipe cleaning system may be enabled with a snake device in order to feed the nozzle, high pressure blade attachment, and other devices down into areas, such as the interior of a pipe, to enable engagement with the blockage.  
         [0032]     A delicate cleaning system is shown in  FIG. 2 . This system may be used to clean small or delicate objects, such as bike chains, jewelry, and the like. As in  FIG. 1  an engine may be coupled with a pump to drive fluid through the system. The pump may use a variety of fluid delivery devices to deliver the fluid to delicate nozzles and plugs. The delicate cleaning system includes several attachments, such as nozzles, for external cleaning and internal cleaning, such as to clean the interior tubing of instruments, like the trumpet shown in  FIG. 2 . The various attachments may be differently sized and shaped for use in accomplishing specific tasks. It is further contemplated that the delicate cleaning system may be enabled as a snake device allowing for the delivery of the fluid stream through confined areas to reach a blockage or cleaning site.  
         [0033]     In a further embodiment, shown in  FIG. 3 , a marine cleaning system is shown. Maintenance of surfaces exposed to marine environments may be important in order to provide an aesthetically pleasing appearance and prolong the life of the surface. Further, by keeping these surfaces clean it may decrease drag on these surfaces, allowing the water to flow smoothly over these surfaces. Unfortunately, many times these surfaces are difficult to reach, this may result from the surfaces being at difficult to reach angles, under the waters surface or any assortment of issues which may arise. Thus, the marine cleaning system provides a user a way to clean those surfaces in marine environments. Similar to  FIG. 1 , an engine operationally coupled to a pump provides a driving force to a fluid within the marine cleaning system. The fluid is transferred through fluid delivery devices into a variety of marine cleaning devices. The marine cleaning devices, may include a deck cleaner/scrubber device for maintaining a boat deck. Further, a water recycling unit may be included to draw water from a variety of water sources for a variety of purposes, such as cleaning. A line cutter assembly may be coupled with the fluid delivery devices in order to provide a way to free entangled lines which have become caught in the propeller, rudder, or other parts of the boat. For cleaning below the surface of the water, the present embodiment may include an in-situ hull cleaner. Other features of the marine cleaning system may include a propeller turning attachment, which may assist in freeing entangled propellers, a bilge pump assembly, which may include bilge cleaning attachments, and a sail cleaning assembly for keeping sails clean.  
         [0034]     In other alternative embodiments, cleaning systems use pressurized hydraulic liquids to drive a foam plug through pipes, cleaning the pipes and clearing clogs. Shower mold removal attachments kits may include grout removal attachments, which provide a concentrated water stream for deep scrubbing, and hot and cold options. Cleaning systems may also include a toilet tank cleaner and high pressure decarbonization systems. Systems may also include rot removal tools used to blast rot out, especially dead wood, termite infested wood, dry rot, rotted posts in cement enclosures. A workpiece chip remover/blower cleaning system keeps a work area clear so the user can see what they are working on. Chimney cleaning systems, employing various chimney cleaning attachments, may allow the user to safely clean the inside of a chimney and may include a specific water reclamation system so the user can blast the water up the chimney from inside, but not wet the inside of the house. Super heated water and high powered steam cleaning systems may be used on decks, stonework, etc. Alternative embodiments may include, oil removal systems, both for on land and in water oil slicks, and may be laid out in a circular fashion to surround and contain the slick for collection. Systems may also include industrial dish washers, assembly line style steam and water jets to clean the dishes, and gutter and brickwork cleaning systems.  
         [0035]     Referring generally now to  FIGS. 4 and 5 , exemplary embodiments of cutting or abrading systems of the present invention are shown.  
         [0036]     In  FIG. 4 a  multi layer finishing tool system is shown, including a gun assembly coupled to a pump via a fluid delivery device. The pump is coupled with an engine to provide a power source to the system. In operation, through use of the gun assembly, the multi layer finishing tool system allows the user to scrape away different depths, creating designs, different colors and patterns. For instance, if a user of the present embodiment had stacked layers of different materials in an area, the present invention would allow the user to direct the removal of layers of material in any manner they select. As  FIG. 4  exemplifies, one area may have several layers removed while other areas may have only one layer removed, or patterns may be established in the layers. The gun assembly may include a variety of nozzles and directional spouts for use with the system. It is contemplated, that template nozzles may be employed.  
         [0037]     In an alternative embodiment, the present invention may be enabled as a compositing machine, as shown in  FIG. 5 . The user feeds yard waste into a compost bin, where it is fed through a series of chopping blades. The user may select to remove the dry ground material or to add water to create a slurry. As shown in this exemplary embodiment, the composting machine is in fluid communication with a fluid pump via a fluid delivery device and the fluid pump is coupled with an engine to provide power to drive the fluid through the pump and the fluid delivery device.  
         [0038]     In other alternative embodiments, cutting or abrading systems may include insulation cutting systems, used to slice fiberglass insulation cleanly, keeping dust and glass particles to a minimum. Graffiti removal systems may employ attachments or tools which may be used to remove paint in the shape of the graffiti design. Deep hole drilling systems may have water that runs as coolant and chip remover through the hole from an attachment to a hand drill or drill press. The water is then collected by a vacuum attachment around the drill site. These systems may also employ high pressure water jet tools used to break up heavy or dense soils (like clay). Very powerful water pick systems allow the user to clean crevices and narrow spaces. Concrete demolition systems may employ tools and attachments which are used to break up slab or pavement. Water auger systems, driven by hydraulic power, allow the excess water to be used to loosen the oil as runoff. Post removal systems may employ a water jet to quickly erode and remove the wood of the posts, leaving the concrete slab in place. For example, when a wood post, encased in concrete, has rotted the post removal system may be employed to remove the rotted wood post but leave the concrete in place. Cutting or abrading systems may further include under water table saws. Water drill systems use a high speed stream of water to punch holes in the work piece, instead of a mechanical drill. Polishing or tumbling systems allow the user to create a surface treatment on finished parts of a workpiece. This may be primarily used for smoothing or deburring. Erosion acceleration systems are used in large scale landscaping to remove sections of hillside. It is further contemplated that various systems may make use of spinning blades at a specific distance from a reference surface, driven by water. These systems may employ various rotary tools used for stone carving, with a variety of attachment heads. Under sidewalk hold digger systems allow the user to remove the dirt from beneath a section of pavement for the purpose of routing cables, etc. The user would then refill the hold without having to replace the pavement. Tile cutter systems of the present invention, may employ a high powered water jet for the cutting of tile instead of the use of a blade. Driveway design systems allow the user to grind designs or textures into their driveway. Flexible arms with a spinning blade attachment at the end of the arms may be employed with these systems. A water driven slitting saw system and other systems such as water driven turbines could drive a variety of spinning blade attachments. Alternatively, systems may employ garbage disposals with water driven blades.  
         [0039]     Recreational uses of hydraulic systems, such as the misting system shown in  FIG. 6 , provide another exemplary embodiment. As shown, the misting system is an in ground system employing a power source coupled with a fluid pump which delivers a fluid, such as water, via underground fluid delivery devices, such as pipes, tubes, and the like, up through a surface and into the immediate environment. The environment, in the present embodiment, is a yard and may include a slip and slide which is coupled with the system and has the fluid running through it. Further, the misting system may be employed for the watering of vegetation, such as plants, vegetables, and the like. A water barrier may be employed to at least partially surround the power source and pump (hydraulic pump system) to aid in limiting noise. The misting system may be employed within a defined environment, such as a greenhouse, to maintain stable environmental conditions or outside to assist in providing a cooler environment or for the watering of vegetation.  
         [0040]     In other alternative embodiments, a snow making system, using a misting attachment, freezes the mist coming out and creates snow. Other alternative embodiments include jet scooter systems for use in the pool, wave pool systems, whirpool generator systems, water jet pack systems similar to the water jet scooter, self circling hola hoops, bubble generators, and the like. A highly directional accelerating slip and slide system is further contemplated. Massaging systems where massage columns power a series of massage balls to move randomly within some column structure and the user then leans up against this column for a massage. Lap swimming systems for use in the pool which generate a strong current and train people for river like conditions or increase the challenge of their work out are contemplated by the present invention. Other embodiments include, geyser seat systems, which use a powerful stream of water to lift the user sitting on a platform into the air, power assisted trampoline systems, and water pogo stick systems are encompassed. Water guidance systems which allow a swimmer to avoid hitting the pool edge by creating a current which steers the swimmer away from the edge may be an alternative embodiment of the present invention. Fountain systems, for use as a lawn fountain or art element which could allow the traditional pressure washer to remain in use for more of the year and steam showers, which would heat the water and mist it, creating an in home sauna, are additional contemplated embodiments.
