Abstract
A motorized power head for a machine for cleaning upholstery, carpeting or hard floors includes a spray nozzle for distributing a clean spray solution on a selected area enclosed by the power head. A cylindrical rotating brush is driven by a two-speed motor housed in the power head to work the solution into the carpet to clean the selected area. A suction nozzle picks up the spent solution together with loosened dirt and grime. The power head may be used as a close-up applicator with a handle adjacent the power head, or as a stand-up applicator with an extension inserted between the handle and the power head. The brush is easily removed for replacement or for converting the apparatus for different applications.
