ABSTRACT:
A cleaning apparatus in the form of a scrubber that is motor driven by a direct current (DC) motor driving a rotatable scrubber unit which includes a scrubber disc with the motor and scrubber disc forming a power head supported from a detachable and adjustable length pole which enables surfaces that are normally out of reach to be easily scrubbed. The scrubber disc incorporates a unique pad structure driven through a unique clutch structure with the power head being supported from the pole and connected with a source of DC electric power through a unique, dependable and longlasting electrical conductor arrangement. Interchangeable scrubber discs are utilized and the scrubber may be powered by a 12 volt DC motor connected to a portable 12 volt battery which may be supported as a backpack or the like, a 12 volt AC/DC transformer, plugged directly into a cigarette lighter on a vehicle or a vehicle battery or to any other source of 12 volt DC electrical power to supply the motor with electrical power to enable the motor to rotate the scrubber disc with adequate torque for scrubbing various surfaces.
