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 motor shaft is affixed to the brush member and supports the brush member. The motor housing is pivotally connected to an elongated main support pole, having an air supply hose disposed therewithin and along the length thereof. The air supply hose exits, through a union, from a peripheral portion of the main support pole and is interconnected with the motor. A fitting is mounted on an opposite end of the main support pole, i.e., remote from the motor, for interconnection with a fluid source through an air hose. An extension support pole fits over the main support pole and can be extended to a preselected position along the length of the main support pole. Rotation of the extension support pole in either direction relative to the main support pole permits locking of the extension pole to the main pole.
