ABSTRACT:
A mobile cleaning unit for providing a high pressure cleaning spray, comprising a van-type vehicle with separate sources of water and cleaning and treating solutions. Valves, one associated with each source, determine the composition of the cleaning spray by individually controlling both the introduction and the proportion of cleaning or treating solution introduced into the water as it is used in cleaning. The individual valves are successively operated in response to each initiation of flow from the source of water. The cleaning or treating solution from a particular source to be used is selected by starting and stopping flow from the source of water by operation of a flow control valve at the spray applicator.
