A high pressure pump ( ) supplies cleaning fluid from a reservoir ( ) to spray nozzles ( ) inside a washing chamber ( ). The spray nozzles ( ) spray the cleaning fluid over a load to be cleaned. Used cleaning fluid is collected in a sump ( ). A sump pump ( ) drains the sump. The combination of the high pressure pump and sump pump provides more efficient cleaning of the load and eliminates the requirement for a deep sump beneath the washer. A vertical traveler ( ), having a pair of counterbalanced spray arms ( ), raises and lowers the spray nozzles counter cyclically; a detergent injection system ( ) accurately meters a correct amount of detergent is added to the cleaning fluid; and a filtration device ( ) filters suspended material from the used cleaning fluid and uses a portion of the cleaning fluid to clean itself.
