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.

9. A power head unit for a carpet cleaner, said power head unit comprising:
-
a housing; means in said housing for defining a brush chamber and a powder retaining chamber for retaining a quantity of a dry chemical carpet cleaning material therein; a brush rotatably supported in said brush chamber, said brush comprising bristles and a substantially circular brush roll supporting said bristles offset from the centerline of said brush roll; means for rotating said brush in a direction opposite that of the offset of said bristles from the centerline of said brush roll so that said bristles sweep against said carpet with an augmented force for agitating said dry chemical carpet cleaning material onto said carpet to perform a cleaning function; said housing further supporting means for selectively dispensing said dry chemical carpet cleaning material from said powder retaining chamber onto said carpet.
