Description:
RELATED APPLICATIONS 
     This application is the National Stage of International Application No. PCT/AU2018/050981 filed 11 Sep. 2018, which claims priority to and the benefit of Australian provisional patent application no. 2017903698 filed on 12 Sep. 2017 with IP Australia, the contents of which are incorporated by reference. 
    
    
     TECHNICAL FIELD 
     The invention relates to an apparatus, a system and a method for cleaning tools and equipment such as a wheelbarrow. 
     BACKGROUND 
     Tools and equipment such as wheelbarrows are used on building sites for a variety of reasons. One use for a wheelbarrow involves the carriage of cement within a tray of the wheelbarrow. During use, the cement becomes caked on inside of the tray and must be cleaned from the tray. 
     To clean the tray, the wheelbarrow may be tipped by a user and rested on the ground or held by a further assisting user. The soiled water and cement are then washed onto the ground or into a drain. A similar process may occur for tools and equipment that may need to be cleaned, for example, trowels that may have caked cement thereon or paint brushes with excess paint. 
     A problem with cleaning such tools and equipment relates to handling of the waste product including solids and contaminated water. A problem specific to the cleaning the wheelbarrow tray relates to the awkward holding of the wheelbarrow or two persons being required. Another problem relates to the soiled water and handling of waster cement that may pollute the surrounding environment. 
     The invention disclosed herein seeks to overcome one or more of the above-identified problems or at least provide a useful alternative.

     DETAILED DESCRIPTION 
     First Example 
     Referring to  FIGS. 1 to 11 , there is disclosed a first example of an apparatus  10  for cleaning tools and equipment such as a wheelbarrow  12  as shown, for example, in  FIG. 6 . Such tools and equipment may be cleaned by using a cleaning fluid such as water to remove matter such as solid material, slurries and debris. 
     The apparatus  10  includes a tub  14  that provides a receptacle  16 , a filter  18  shaped to be fitted to the receptacle  16  in a fitted condition and a support arrangement  19  adapted to at least temporarily hold the wheelbarrow  12  in a tipped orientation relative to the receptacle  16 . 
     In the tipped orientation, matter within a tray  20  of the wheelbarrow  12  is moveable at least partially via gravity into the receptacle  16 . For example, the cleaning fluid such as water may be applied to the tray  20  to wash matter into the receptacle  16  with solid material being at least partially captured by the filter  18  and the water passing through the filter  18 . 
     The tub  14  includes a front wall  22  with a cut out  24 , a back wall  26  opposite the front wall  22 , opposing side walls  28 , a base  30  and a skirting rim  32  extending substantially atop the back wall  26 , opposing side walls  28  and at least partially about atop of the front wall  22 . The skirting rim  32  may be the same width as or wider than the respective walls,  22 ,  26 ,  28 . 
     The walls  22 ,  26 ,  28  of the tub  14  define an opening  34  into the receptacle  16  and taper slightly toward the base  30  such that the platform area of the base  30  is less than the opening  34 . 
     The cut out  24  is shaped to receive at least a leading portion  36  of the tray  20  in the tipped orientation and may cradle and support the tray  20  depending on the fit between the cut out  24  and the tray  20 . In some examples, the cut out  24  may provide the support arrangement  19  by supporting and holding the wheelbarrow  12  in the tipped orientation. However, in other examples, the cut out  24  may simply provide access to the receptacle and may not engage directly with the tray  20 . In this example, the cut out  24  forms part of the support arrangement  19  in combination with tray supports  48  as are further detailed below. 
     The cut out  24  includes opposing side sections  38  extending from the skirting rim  32  to an intermediate section  40  that is relatively lower than the rim  32  and relatively above the base  30 . The height of the intermediate section  40  is arranged such that the tray  20  is movable thereover without elevating a wheel  42  of the wheelbarrow  12  relative to the receptacle  16  which allows the wheel  42  to generally remain in contact with a ground surface without elevation or lifting of the entire wheelbarrow  12   
     The intermediate section  40  includes an intermediate lip  44  extending along a top thereof. The intermediate lip  44  is substantially horizontal and extends relatively outwardly from the front wall  22  of the tub  14 . The opposing side sections  38  are shaped to cradle the tray  20  of the wheelbarrow  12  in the tipped orientation and may be curved or angled such that that the cut out narrows  24  toward the intermediate section  40 . The side sections  38  include respective side lips  46  against which the tray  20  of the wheelbarrow  12  bears in the tipped orientation. 
     In this example, the support arrangement  19  includes a pair of tray supports  48  arranged to abut with the leading portion  36  of the tray  20  in the tipped orientation. The pair of tray supports  48  may take various forms that function to provide a stop to inhibit over tipping of the wheelbarrow  12  and at the same time provide a retainer that fittingly holds a rim of the tray  20 . 
     In more detail, in this example, the tray supports  48  include a body  50  pivotally coupled to the front wall  22  adjacent the cut out  24  and projections  52  that extend from the body  50  adapted to engage with the leading portion  36  of the tray  20 . 
     In this arrangement, the tray supports  48  are moveable from a first position, as shown in  FIG. 8 , in which the tray supports  48  are rotated away from the rim  32  to allow the filter  18  to be fitted. Once the filter  18  is fitted, the tray supports  48  may be rotated adjacent the rim  32  atop of the filter  18 . Accordingly, the tray supports  48  also function to capture and secure the filter  18  in place. 
     In this example, the projections  52  include a rear most larger projections  54  that defining a narrower gap therebetween and forward most smaller projections  56  that define a relatively larger gap therebetween. This allows the projections  52  to abut with trays  20  having differing sizes. The notches  58  between the projections  52  also assist to capture a rim of the tray  20  to retain the wheelbarrow in the tipped orientation. It is noted that in some examples the tray supports  48  may be omitted, and especially in examples in which the cut out  24  is adapted to snuggly hold the tray  20 . Further, in other examples, the tray supports  48  may be formed integrally with the tub  14 , as is shown in respect of the second example below. 
     The support arrangement  19  may further a tether  60  arranged to secure the wheelbarrow  12  in the tipped orientation. In this example, the tether  60  is an elastic strap  62  having hooks  64  at opposing ends thereof adapted to releasably couple to the tub  14  on opposing sides of the cut out  24 . The strap  62  may be passed about the wheelbarrow  12  to secure the wheelbarrow  12  for cleaning, in particular, more vigorous cleaning and scrubbing. 
     Turning now to the filter  18  in more detail, the filter  18  may be pre-shaped to substantially line an internal surface  62  of the receptacle  16 . The filter  18  includes a filter body  64  shaped to correspond to an internal shape of the tub  14 . The filter body  64  includes a front wall  66  having a cut out  68 , a back wall  70 , opposing side walls  72  and a base  74 . The cut out  68  corresponds to the cut out  24  of the tub  14 . 
     A skirting flap  76  extends substantially atop the back wall  70 , opposing side walls  72  and at least partially atop of the front wall  66 . The skirting flap  76  of the filter  18  is arranged to locate atop of the skirting rim  32  of the tub  14  in the fitted condition. The filter  18  includes an intermediate flap  78  adapted to extend atop the cut out  24  in the fitted condition. In this example, handles skirting flap  76  at the opposing sides walls, rear wall and intermediate flap each include a handle  80 . The handles  80  generally extend proud of the tub  14  to allow for ease of clasping and removal of the filter  18 . 
     In terms of material, the filter  18  may be formed of various materials including, but not limited to, one or more of paper, cellulose, hemp, banana fibre, nylon, polyester, synthetic textiles and recycled textiles. The filter material is adapted to filter solid material from the fluid. For example, the filtered solid material may be cement and parts thereof such as sand and gravel. Fluid substantially including water passing through the filter  18  and toward the base  30  of the receptacle  16 . 
     In this example, the filter material may be a filter paper with a single layer cellulose with a weight of about 180 GSM and pore retention size of 5-10 μm. The filter paper may be wet strengthened with an Epichlorohydrin Resin. The cleaning fluid may take about 20 minutes to drain through the filter. The filtration process may be assisted by a phenomenon known as a ‘filter cake’ which is when the captured solids/sediments sitting in the lowest point of filter act as a secondary filter. 
     The tub  14  includes an outlet  82  through which the receptacle  16  drains and the inside surface  62  of the receptacle  16  of the tub  14  is adapted to promote flow of fluid through the filter  18  toward the outlet  82 . The inside surface  62  of the receptacle  16  generally slopes toward the centre and rear of the tub  14  and the outlet  82  is provided at the centre and rear of the tub  14 . 
     At least some of the inside surface  62  adjacent the filter  18  adapted to promote flow of fluid through the filter  18  such as by being not smooth or not flat against the filter  18 . In more detail, in this example, the inside surface  62  adjacent the filter  18  includes surface features in the form of ridges  84  and troughs  86  that support the filter  18  whilst providing, in essence, spaces or conduits via the troughs  86  to allow fluid to pass the filter  18  and flow toward the outlet  82 . 
     It is noted that whilst in this example, ridges  84  and troughs  86  are provided, the internal surface  62  may be provided with various surface features that provide a similar function such as, but not limited to, one or more of corrugations, projections, ridges, apertures and recesses. The surface features may also be provided by separate part or insert e.g. wire mesh basket that fits below the filter  18 —all of which are contemplated herein. 
     Turning to the outlet  82  in more detail, the outlet  82  is arranged to be fittable with a hose  88  and/or a fluid treatment device  90 . In this example, the fluid treatment device  90  is adapted to alter the pH of fluid passing therethrough. The fluid treatment device  90  includes a housing  92  and ion-exchange media  93  retained within a stainless steel mesh bag  94  within the housing  92 . It is noted that the fluid treatment device  90  may be omitted from some examples. The ion-exchange media  93  may be or include cation exchange resins such as, but not limited to, strongly acidic cation exchange resin. 
     It is noted that in some examples, the apparatus  10  may omit the filter  18  per se and include the fluid treatment device  90  perhaps with a pre or post filter between the outlet  82  and the fluid treatment device  90  or hose  88 . Such a configuration is contemplated herein. 
     The apparatus  10  may further include a removable tray or tub  96  adapted to seat atop of tub  14  and filter  18 . In this example, the removable tray  96  includes a receptacle  97  with drainage apertures and wings  98  that seat atop of the rim  32 . The removable tray or tub  96  may be used to clean smaller tools and equipment. It is noted that in some examples, the cut out  24  may be omitted and the tub  14  and filter  18  may be used to clean tools and equipment other that wheel barrows. 
     In some examples, the apparatus  10  may further include a reservoir  99  adapted to collect filtered fluid from the tub  14 . The reservoir  99  is provided within a body  85  that provides a platform  87  on which the tub  14  and wheelbarrow are locatable. The body  85  includes a ramp  89  to the platform  87 . The reservoir  99  includes an inlet  91  that is connectable to the hose  88  and/or a fluid treatment device  90 . The reservoir  99  may find use in situations where temporary waste storage is required. 
     The tub  14  and other components may be generally formed of, but not limited to, a plastic material such as polyethylene, nylon and polypropylene. The components of the apparatus may be considered to form part of a system or kit that function together. As such, the components of the apparatus such as the tub, filter, platform reservoir and fluid treatment device may be provided separately. 
     In use, a method for cleaning the wheelbarrow  12  with a fluid, may include one or more of the following steps. Firstly, locating the tub  14  on a ground surface or on the platform  87  of the reservoir  99 . The tray supports  48  may be elevated and the filter  18  is fitted to the receptacle  16  of the tub  14 . The tray supports  48  may then be lowered to secure the filter  18 . 
     The wheel barrow  12  is then moved toward the tub  14  in an initial orientation with at least the leading portion  36  of the wheelbarrow  12  received by the cut out  24  of the tub  14  and over the receptacle  16 . The wheelbarrow  12  is then moved to a tipped orientation relative to the receptacle  16  such that matter within the tray  20  of the wheelbarrow  12  is moveable at least partially via gravity into the receptacle  16 . The tray is abutted with the tray supports  48  that form part of the support arrangement  19  to hold the wheelbarrow  12  in the tipped orientation. The wheelbarrow  12  may be optionally retained in the tipped orientation with the tether  60 . 
     A cleaning fluid such as water is then applied to the tray  20  of the wheel barrow  12 , and matter or mixture including solids and water is washed into the receptacle  16 . The wheelbarrow  12  may be removed at this point or remain in place to dry. 
     The solid material is then substantially captured within the filter  18  and fluid passes via the outlet  82  into the hose  88  and/or fluid treatment device  90 . The fluid is then treated to adjust to the pH to that closer to water, say, toward a pH of about 7. Once the fluid has passed the filter  18 , the wheelbarrow  12  is removed (if not done so already) and the tray supports  48  may be elevated to release the filter  18 . The filter  18  may then be removed via the handles  80  and the filter and solid material may be disposed of. It is noted that multiple wheelbarrows, equipment and tools may be washed using a single filter  18 . However, once soiled to a point of inhibiting filtration, such as becoming clogged with cement, the filter may be replaced. 
     Advantageously, the apparatus allows a wheelbarrow and tools to be cleaned whilst capturing the wastewater and any solid material such as cement. The filter is able to be removed to safely dispose of captured material and the remaining water is able to be collected for disposal or treatment. 
     The support arrangement allows the wheelbarrow to be held for hands free cleaning and the integrated cut out allows the wheelbarrow to be tipped without lifting the entire wheel barrow. Tools may be supported by the cleaning tray above the tub that allows simultaneous cleaning of the wheelbarrow and tools whilst keeping waste water contained. 
     Second Example 
     Referring now to  FIGS. 12 to 15  there is provided a second example of the apparatus  110  in which like sequences of numerals denote like parts (i.e  10 ,  110  etc). Many components of this second example of the apparatus  110  are similar to the above described first example and are not again repeated here. Rather, the main features and differences are highlighted. 
     Turning to the second example of the apparatus  110  in more detail, the second example of the apparatus  110  is substantially similar to the first example. However, the tub  114  is provided in two parts including a lower tub section  115  and an upper tub section  117  that fit together in an assembled condition. 
     The upper tub section  117  includes a support arrangement  119  having a cut out  124  in a front wall  122  thereof that is shaped to support and cradle the tray  20  of the wheel barrow  12  and tray supports  148  are integrally formed at opposing side walls  128  of the upper tub section  117 . The tray supports  48  include projections  152  that are oriented toward one another to define a gap narrower than a width of the tray  20  so as to provide a stop for the tray in the tipped orientation. 
     Like the first example, the projections  152  include a rear most larger projections  154  that define a narrower gap therebetween and forward most smaller projections  156  that define a relatively larger gap therebetween. This allows the projections  152  to abut with trays  20  having differing sizes. The apparatus  110  may also include a tether  60  to retain the wheel barrow in the tripped orientation against the tray supports  48 . 
     The lower tub section  115  includes a base  130 , opposing sides walls  129 , opposing front and back walls  131  and a skirting rim  132 . The lower tub section  115  provides a generally rectangularly shaped receptacle  116  defining an opening  134  in which the filter  118  is fittingly received. Like the first example, the internal surface  162  of the receptacle  116  is not flat or smooth and include ridges  184  and troughs  186  to assist with movement of fluid through the filter  118 . 
     However, of course, other surface features such as apertures, undulations or the like may also be utilised. An outlet  182  is located at the back wall adjacent the base  130  to which a hose  188  and/or a fluid treatment device  190  may be fitted. The fluid treatment device  190  has already been described in relation to the first example and will not be again described here. 
     In this example, the filter  118  is rectangularly shaped to fit with the lower tub section  115  and includes a front wall  168 , a back wall  170 , opposing side walls  172  and a base  174 . A skirting flap  176  extends about the walls  168 ,  170 ,  172 . The skirting flap  176  is dimensioned to extend over the skirting rim  132  of the lower tub section  115 . 
     Accordingly, in an assembled condition, as shown in  FIG. 12 , the skirting flap  176  may be captured between the upper and lower tub sections  115 ,  117  that assist to retain the filter  118  in place during use. The material of the filter  118  may be the same as the first example and is not again repeated here. The filter  118  may include handles  80  that are accessible to remove the filter  118  when the upper and lower tub sections  115 ,  117  are disassembled as shown in  FIG. 13 . The second example may also include a removable tray  196  that seats in use atop the upper tub section  118 . 
     The method of use may also be similar to the first example. However, of course, the filter  118  is installed within the lower tub section  115  prior to the upper tub section  117  being fitted to the lower tub section  115 . 
     Third Example 
     Referring now to  FIGS. 16 to 20  there is provided a third example of the apparatus  210  in which like sequences of numerals denote like parts (i.e  10 ,  210  etc). Many components of this third example of apparatus  210  are similar to the above described first example and are not again repeated here. Rather, the main features and differences are highlighted. 
     Turning to the third example of the apparatus  210  in more detail, the third example of the apparatus  210  is again substantially similar to the first example. However, the tub  214  is shaped to be moveable from an initial generally horizontal position to an angled position as shown in  FIGS. 16 and 17 . 
     In more detail, in this example, the tub  214  includes a receptacle  216  having a lower portion  215  that steps to an upper portion  217  such that a step  219  is provided between the lower portion  215  and the upper portion  217 . The step  219  allows the tub  14  to either rest on a base  230  of the lower portion  215  or be rolled over to the angled position in which the tub rests on corners  221 ,  223  of the lower portion  215  and upper portions  217 , respectively. 
     The step  219  functions to allow the tub  14  to be filled with matter and solid material within that matter to accumulate or settle via gravity more so in the lower portion  215  as shown in  FIG. 17 . In this tripped orientation, the step  219  provides a divider  227  between the lower and upper portions  215 ,  217  and matter, namely fluid with less solids is present in the upper portion  217 . This assist the filter  218  to function more effectively as there is less sold material in the upper portion to block the filter  218 . The step  219  also provides a nook  229  in which the hose  288  and/or fluid treatment device  290  may be positioned. 
     In this example, the tub  214  includes two outlets  282   a  and  282   b  in the lower and upper portions  215 ,  271 , respectively. The two outlets  282   a  and  282   b  are elevated in the angled position to allow for drainage above any collected solid material as shown in  FIG. 17 . 
     The two outlets  282   a  and  282   b  are connected to the fluid treatment device  290  internally via conduits  283   a ,  283   b  thereby allowing fluid drainage via paths A and B at a lowest point of the lower and upper portions  215 ,  217  of the receptacle  216  in the angled position. The fluid treatment device  290  may then be connected to a hose  288  in a similar manner to example 1 and not again described here. 
     The filter  218  may be formed in a similar manner as described above in relation to example 1. However, of course, the shape of the filter  218  also includes a step  231  to correspond to the shape of the tub  214 . The apparatus  210  includes a cut out  224  and tray supports  248  that are similar to that as described above in relation to example 1 and as such these parts are not again described herein. 
     In use, the tub  214  may initially be in an initial position in which the leading portion  36  of the wheel barrow  12  is received by the cut out  224  and is supported or located by the tray supports  48 . A tether  260  may be used to retain and secure the wheel barrow  12  to the tub  214 . It is noted that in this example, the tethering of the wheel barrow  12  may render the entire assembly self-supporting for ease of cleaning. 
     Once the wheel barrow  12  has been cleaned and the matter including solids and water is within a receptacle  216  of the tub  214 . The wheel barrow  12  may be detached from the tub  214  and the tub  214  may be rotated to the angled position to allow for drainage from the outlets  282   a ,  282   b . The tub  214  may be rocked to assist with filtration and drainage, as required. The filter  218  may be removed once soiled and replaced as need be. 
     Fourth Example 
     Referring to  FIGS. 21 to 28 , there is shown a fourth example of an apparatus  305  in the form of a stand  310  for cleaning a wheelbarrow  312 . The stand  310  is adapted to support the wheelbarrow  312  so as to be elevated in a tipped orientation, as shown in  FIG. 28 , relative to supporting surface  314  such that material or fluid within a tray  316  of the wheelbarrow  312  is moveable at least partially via gravity in a direction from the tray  316  toward the supporting surface  314 . 
     The stand  310  may be provided as part of a system  320  that further includes a receptacle  322  arranged relative to the supporting surface  314  such that in the elevated tipped orientation material or fluid from the tray  316  is directed toward and captured by the receptacle  322 . 
     The receptacle  322  may take any form in which material or fluid within the tray  316  is moveable at least partially via gravity in a direction from the tray  314  toward the receptacle  322 . The receptacle  314  may be any suitable means to collect, capture, direct or funnel fluid or material, and may be a vessel, tub, container, pipe, funnel, drain or the like. Preferably, however, the receptacle  322  is a tub or vessel  324 . The arrangement of the supporting surface  314  may include more than one surface such as a stepped surface, or straight or sloped ground surface. 
     Turning to the stand  310  in more detail, the stand  310  includes a frame  326  having a first support  328  on which a first part  330  of the wheelbarrow  312  is supportable and a second support  332  adapted to support a second part  334  of the wheelbarrow  312  elevated above the first part  330  so as to at least temporarily retain the wheelbarrow  312  in the tipped orientation. The stand  310  includes first legs  342  toward a leading or entry end  343  of the stand  310 , and second legs  344  toward opposing ends  345  of the stand  310 . 
     The first support  328  is arranged to support a wheel end  336  of the wheelbarrow  312  and the second support  332  is arranged to support the at least one of the tray  316  and handles  338  so as to at least temporarily retain the wheelbarrow  312  in the tipped orientation. 
     In this example, first support  328  includes a wheel stop  340  against which the wheelbarrow may be pivoted to the tipped orientation and engaged with the second support  332 . In more detail, the first support  328  is a generally horizontal section of the frame  326  having two spaced apart lengthwise frame members  346  elevated above supporting surface  14  via the first and second legs  342 ,  344  which are pivotally coupled to each of the two spaced apart lengthwise frame members  346 . 
     The wheel stop  340  may be provided as a pair of cross members  348  interconnecting extending latterly of the lengthwise frame members  346 . The first support  328  may take a variety for forms such as an open frame with cross members  328  as shown here or the first support  328  may be or include a platform or other means to support the wheel end  336  of the wheelbarrow  312 . 
     The second support  332  may be provided in form of a pair of arms  350  arranged to support the tray  316  of the wheelbarrow in the tipped orientation. The pair of arms  350  may be resiliently sprung (such as being formed from spring steel or the like) to resiliently hold opposing sides of the tray  316 . The arms  350  are splayed and include outward turned ends  356  to assist with fitted of the tray  316  between the arms  350 . 
     The stand  310  includes a ramp  352  leading to and pivotally coupled to the first support  328  and arranged to allow the wheelbarrow  312  to be wheeled up the ramp  352  to the first support  328 . In this example, the first and second legs  342 ,  344 , and the ramp  352  are foldable to allow the stand  310  to be foldable between a deployed condition in which the wheelbarrow  312  is supportable in the tipped orientation and a generally flat stowed condition. 
     In this example, the pair of arms  350  are each contiguous with respective ones of the second legs  44  such that the pair of arms  350  and second legs  344  are simultaneously folded with one another. The ramp  352  is wider than the first leg  342  and may include a recess  354  on an underside thereof to at least partially receive the first leg  342  in the stowed condition. The second legs  344  include apertures  347  through which fasteners  349  (such as a bolt or pin) may fitted to corresponding apertures  351  of the first support  328  thereby allowing locking of the second legs  344  in the fitted deployed condition. It is noted the first legs  342  rotated past 90 degrees and abut with the first support  328  thereby being retained by the weight of the stand  310 . 
     Turning to the system  320  in more detail as shown in  FIG. 28 , the system  320  is preferably arranged with the vessel  324  arranged below the tray  316  of the wheelbarrow  312  in the tipped orientation. The vessel  324  is generally fitted below two spaced apart lengthwise frame members  346  of the frame  326  with the second legs  344  in the vessel  324 . The arms  350  may be positioned toward one end or intermediate the vessel  324  such that when cleaning fluid (i.e water) is applied to the tray, the fluid material mixture within the tray  316  is moveable at least partially via gravity toward and into the vessel  324 . 
     In some examples, the system  320  further includes a filter  360  fittable between the tray  316  and the vessel  324 . The filter  360  is adapted to selectively capture solid material of the fluid material mixture thereby separating such material from the cleaning fluid. The cleaning fluid is therefore maintained relatively clean and may be reused or disposed of as per examples 1-3 above. The filter  360  may be secured across an opening of the vessel  324 , or may be suspended from the frame  310 . The filter  360  may be a filter material such as a geo-fabric, or paper, hemp etc as described above. 
     In some examples, the filter  360  may be removable or replaceable such as a cartridge or unit adapted to be fitted to the vessel  324 . The use of the filter  360  allows for re-use of the contained water that has passed through the filter  360 . It may be bucketed back into a cement mixer the following day or pumped with a small submersible pump to another location. In some examples, the vessel  324  may include valve and tap that allows the excess cleaned water to be drained to another location via gravity. This may simply be a bung hole and plug with hose attached 100 mm above the bottom of the vessel  324 . In some examples, the height of the wheelbarrow stand  310  may be adjustable so that it can be raised to suit vessels  324  with higher sides. 
     Turning to a method of cleaning a wheelbarrow using the above system  320 , the method generally includes the steps of: elevating the wheelbarrow  312  using the ramp  352  and supporting the wheel end  336  thereof on the first support  328 . The wheel end  336  is abutted with the wheel stop  340  and the handles  338  are lifted to pivot the wheelbarrow to the tipped orientation with the tray  316  supported by the second support  332 , in this example, the arms  350  that resiliently capture and support opposing sides of the tray  316 . The wheelbarrow  312  is then supported in the tipped orientation with the tray  316  thereof located above the vessel  324 . It is noted that the stand  310  may firstly need to be moved between the stowed and the deployed conditions. 
     In some examples, the filter  360  is arranged substantially such that a fluid material mixture is passed from the tray  16  through the filter  360  into the vessel  324 ; and applying a cleaning fluid, such as water, to the tray  316  such that the fluid material mixture within the tray  316  is moveable at least partially via gravity toward the vessel  324  with at least some solid material carried by the fluid material mixture being captured by the filter  360 . The filter  360 , that may be a material filter, may then be discarded along with the collected solids and the captured water may be reused. 
     Advantageously, there has been described examples of an apparatus, associated systems and methods of use that allows for easy, convenient, safe and environmentally friendly cleaning of tools and equipment, in particular, wheelbarrows. 
     The provided examples allow the wheelbarrow and tools to be cleaned whilst capturing the wastewater and any solid material such as cement. The filter is able to be removed to safely dispose of captured material and the remaining water is able to be collected for disposal or treatment. 
     The support arrangement allows the wheelbarrow to be held for hands free cleaning and the integrated cut out allows the wheelbarrow to be tipped without lifting the entire wheel barrow. Tools or other equipment may be supported by the cleaning tray above the tub that allows simultaneous cleaning of the wheelbarrow and tools whilst keeping waste water contained. 
     The filter may be pre-shaped for ease of fitting and may include handles for ease of removal and disposal of the contained captured material. The internal surfaces of the tub include surface features to assist with movement of fluid, typically water, past the filter and the fluid treatment device assist to adjust the pH of the fluid after filtration such that the fluid, in particular, waste water may be disposed of onsite in a more environmentally friendly manner. 
     In one example the apparatus may include a wheelbarrow stand that advantageously allows the wheelbarrow to be supported in an elevated tipped position to allow for ease of cleaning over a collection vessel. The stand is easily foldable and transportable. The stand may be provided as part of a system including the stand, the collection vessel and the filter. The arrangement of the system being such that the wheelbarrow may be cleaned generally over the collection vessel with the filter collecting the solid material thereby leaving a cleaning fluid, typically water, in the collection vessel that may be reused or disposed of safely, and the collected solid material may be discarded.
