发明名称 Carpet cleaning implement
摘要 The invention is concerned with a carpet cleaning implement useful for continuously washing and rinsing a floor fastened carpet in a single operation. The implement includes a head adapted to be rolled along on a carpet upon wheels. The head includes adjacent its bottom a first row of jets for delivering a flow of a solution of a washing composition such as rug shampoo, under pressure, into the carpet. An oscillatory brush is provided near to the first row of jets for vigorously agitating the solution into the carpet. A second row of jets are located near the brush on its other side. The second row of jets serves to deliver a flow of rinse water under pressure into the carpet. Next to the second row of jets is a channel which communicates with a vacuum source of at least about 100 inches of water for picking up the combined solution and rinse water as the head is rolled along the carpet in a direction whereby the first row of jets passes over a portion of the carpet followed sequentially by the brush, the second row of jets and the channel. A handle is provided extending from the head whereby an operator can direct and control the motion of the head over the carpet. A valve is provided on the handle in easy position for operator control. The valve communicates with a liquid source and serves to simultaneously control flow of the solution through the first row of jets and of the rinse water through the second row of jets.
