Carpet cleaning
First Claim
1. The method of cleaning an area of a pile carpet which comprises providing a cleaning pad in pressure contact with the pile surface of the carpet, providing a liquid cleaning solution at the area of the carpet being cleaned by moistening the carpet area or the cleaning pad or both, establishing rubbing contact between the cleaning pad and carpet pile, and simultaneously generating and accumulating a charge of static electricity between the carpet and pad of sufficient magnitude to force migration of dirt particles and soil materials into the pad.

Abstract
A carpet is cleaned by establishing rubbing contact between the carpet and a cleaning pad thereby generating a charge of static electricity. The static charge is accumulated in sufficient magnitude to force migration of carpet soil into the pad. Alternatively, the static charge may be generated by rotation of a plastic static charge accumulator relative to stationary brushes in contact therewith.

17. The method of cleaning a carpet which comprises rotating a flat circular cleaning pad in pressure contact with the upper surface of the carpet, providing a static charge accumulator electrically connected between the pad and ground and of sufficient capacity to maintain a static charge between the carpet and pad effective to cause migration of carpet soiling material into the cleaning pad in which the static charge is provided by friction between the rotating cleaning pad and the carpet.
