ABSTRACT:
A power head device for use with an external source of vacuum, which device includes an outer housing defining therewithin, in one embodiment, a brush chamber, a vacuum chamber and a dry chemical carpet cleaning powder retaining chamber. The powder retaining chamber is situated adjacent the brush chamber and is further fashioned with a device for selectively dispensing the powder onto a carpet. 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.
