ABSTRACT:
A mobile cleaning unit for providing high pressure cleaning and rinsing sprays, comprising a van-type vehicle with separate sources of water and cleaning and treating solutions. The sprays may be heated by a self-contained water heater with a fuel ignitor operated by low voltage direct current. The separate solutions are selected by a pressure switch sensitive to an increase in spray line pressure caused by stopping the spray by operation of a valve at the spray applicator. The pressure switch acts to sequentially open a supply valve for each solution in turn.
