ABSTRACT:
A method and apparatus for cleaning carpet. The pile of the carpet is first lifted, opened and agitated by stiff rotating brushes and beater bars, separating the foreign matter therein from the pile and bringing the matter to the surface of the carpet. The carpet is then vacuumed removing the separated matter therefrom. A film of cleaning agent is then sprayed through a hand-held wand over the carpet encapsulating the carpet fibers. The wand communicates with a portable pressurized supply of cleaning agent. After a short setting, the carpet is scrubbed with counter-rotating or rotary brushes. The agent is then allowed to dry and the residue removed with a vacuum.
