A motorized vacuum brush head for use with a vacuum. The brush head has a body with an air passage passing though it. The face of the brush head faces the surface being cleaned. A rotatable brush and the air passage mouth are on the face. The brush is flat and has an axis of rotation substantially perpendicular to the face. The brush rotates parallel to and substantially co-planar with the face. Several arms of bristles extend radially from the brush's axis of rotation. As the brush rotates, the leading edge of the bristles drive debris toward the mouth, where it becomes entrained in the air stream entering the vacuum. The rotation of the brush in the plane of the face allows the bristles to remain in continuous contact with the surface being cleaned, thereby increasing the efficiency with which the brush head, and by extension, the vacuum clean.
