A horizontally oriented brush is provided having bristles offset with respect to a centerline thereof so as to provide improved agitation of the powder into a carpet on rotation of the brush opposite the direction of the offset during a cleaning mode of operation. In a vacuum mode of operating, the brush rotates in the direction of the bristle offset and towards the vacuum chamber of the housing.
