The powder retaining chamber is fashioned with at least one slot extending adjacent the brush chamber which slot is closed off by a covering device such as a sliding door. The sliding door is fashioned with apertures the size of the at least one slot so that correspondence thereof will permit the dry chemical carpet cleaning material to escape from the slot. A powder dispensing roll is provided internally of the powder retaining chamber to convey the dry chemical carpet cleaning material to the slot. The power head device may be utilized in a vacuum mode of operation as a vacuum cleaner, or in a cleaning mode of operation as a carpet cleaner, in which latter mode provision may be made to separate the source of vacuum from the vacuum chamber so as to permit the dry chemical carpet cleaning powder to be thoroughly mixed in the rug fibers without removal thereof.
