ABSTRACT:
A power brush housing assembly formed by a wheeled chassis with a housing overlying the chassis and fixed thereto bears transversely, an elongated scrubbing brush roller, and a motor for driving the brush roller to scrub the surface traversed by the power scrubber. A triangular shaped vacuum recovery head is hinge mounted to the face of the housing to permit tilting of the head from its normal vertical orientation to an inclined orientation and to effect movement of the mouth of the vacuum recovery head away from the surface being scrubbed to permit the power scrubber to move over minor obstructions.
