Abstract: A waste receptacle is provided at the bottom of a mobile, wheeled, open topped vessel. A suction pipe in the vessel is coupled to, and extends from, a water supply pipe into the vessel. A drain pipe extends from the vessel at the bottom thereof for draining water from the vessel. A motor driven pump and a plurality of valves mounted on the outside of the vessel selectively apply the pump to the pipes whereby in one valve operation the pump supplies water via the water supply pipe under pressure and the output of the nozzle cleans the surface of an item onto which it is directed in the vessel so that material removed from the item is collected in the waste receptacle, and in another valve operation, the pump draws water or water mixtures from the vessel through the suction pipe and discharges under pressure via a high pressure hose and nozzle. In another valve operation, the pump draws water from the water supply and discharges it under high pressure via a high pressure hose for external cleaning.
