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.
