ABSTRACT:
A conversion attachment for a wet-dry vacuum cleaner provides for the application of a mixture of water and detergent through a spray assembly mounted adjacent to a vacuum nozzle on a cleaning head. The attachment includes a spray nozzle and associated liquid flow lines for connection to a source of water, a detergent container, and a siphon for injecting detergent into the pressurized flowing water. The attachment may also include a substitute wand and cleaning head. The siphon includes a slideable valve member which, in one position, permits mixing of the detergent and water for supply to the spray nozzle. In another position, the valve member blocks flow of all liquid to the spray nozzle.
