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.
Cette invention concerne un accessoire mécanique pour machine à nettoyer les meubles rembourrés, les tapis ou les planchers à revêtement dur. L'accessoire comprend un gicleur de solution nettoyante à l'intérieur de son enveloppe ainsi qu'une brosse rotative cylindrique mue par un moteur à deux vitesses et servant à faire pénétrer la solution nettoyante dans le tapis à nettoyer. Un suceur assure la récupération de la solution nettoyante et l'enlèvement des saletés délogées. L'accessoire mécanique peut servir d'applicateur manuel grâce à une poignée contiguë ou d'applicateur-balai grâce à un tube-rallonge monté sur la poignée. La brosse s'enlève facilement pour fins de remplacement ou pour convertir l'accessoire à d'autres fonctions.
