ABSTRACT:
A carpet cleaning machine comprising a rotary, plastic, static accumulator, drive means for rotating the accumulator, and a pile fabric cleaning pad driven by the accumulator. Preferably the accumulator is directly connected to a nipple pad making driving connection with the rear of the cleaning pad. A bleed connection including an adjustable spark gap limits the charge which the accumulator may carry, and a safety switch discharges the accumulator when the cleaning machine is tilted to expose the accumulator or parts electrically connected thereto.
