ABSTRACT:
A self-contained carpet soil extractor requiring only external contacts to electricity, water and a waste drain is disclosed. A cleaning agent is automatically mixed with water, sprayed on the pile of the carpet, agitated into the pile to loosen and flush any dirt to the surface, and the grimy solution is removed by the apparatus. The dirt is then filtered from the liquid which is pumped to the waste drain.
