摘要:
A hand carried, manually operated apparatus for cleaning flooring, carpet, upholstery, and the like includes a cleansing fluid chamber, a waste fluid chamber, a pump and an applicator. A first fluid passageway connects the pump and cleansing fluid chamber, a second passageway connects the cleansing fluid chamber and applicator, a third passageway connects the applicator and waste fluid chamber, and a fourth passageway connects the waste fluid chamber and pump. A first one-way valve permits flow from the pump to the cleansing fluid chamber but inhibits reverse flow; and a second one-way valve permits flow from the applicator to the waste fluid chamber but inhibits reverse flow. Air is transferred through the pump from the waste fluid chamber to the cleansing fluid chamber as cleansing fluid is transferred to the applicator from the cleansing fluid chamber and waste fluid is transferred from the applicator to the waste fluid chamber.
