ABSTRACT:
A lightweight pneumatic powered portable scrubbing tool is disclosed having a scrubbing brush member that is rotated by a cylindrically-shaped elongated air powered motor. The brush member has a substantially circular mounting plate and a plurality of bristles affixed to a surface of the plate. At least a portion of the bristles are adjacent the periphery of the plate and are directed at an angle outwardly therefrom. The motor shaft is affixed to the brush member and supports the brush member. The motor housing is pivotably connected to an elongated main support pole, having an air supply hose disposed therewithin and along the length thereof. The air supply hose exits from a peripheral portion of the main support pole and is interconnected with the motor. A quick-disconnect fitting is mounted on an opposite end of the main support pole, i.e., remote from the motor, for interconnection with a fluid source, or a secondary main support pole. An auxiliary support pole is interconnected with the main support pole at a preselected position along the length of the main support pole. The auxiliary support pole is extensible.
