摘要： 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.

摘要： An aerosol cartridge is used to supply foam detergent directly to a polyurethane open cell sponge roller having discrete spaced radial cavities open to the outside for receiving the foam and transfer the same to the fabric of upholstery and the like. The cavities constitute working chambers which tend to be compressed as the lands between the same flex and compress in pressure contact with the fabric upon rolling thereover to thereby force the foam through the fabric, and which then suck the foam back through the fabric as the chambers expand on the back side of the roller. The cavities may be in the form of cylindrical holes burned into the sponge whereby the pores at the inner surfaces of the holes are generally closed by a skin effect.
