Abstract
Abstract The present invention relates to a method and apparatus for cleaning upholstery which involves minimal risk of dye bleeding and which is reasonably effective. The invention uses a hand-held applicator and a remote unit. A jet nozzle on the hand-held applicator sprays cleaning solution onto the upholstery. Secured adjacent to the jet nozzle is a brush which imparts mechanical energy to the upholstery and aids in cleaning. Disposed above the brush is a vacuum head that removes the cleaning solution from the upholstery. Air is induced into the vacuum head by a blower secured within the remote unit. The air effectively lifts the cleaning solution from the upholstery and carries the cleaning solution into the vacuum head. Once inside the vacuum head, the combined mixture of air and cleaning solution is directed through a hose into a recovery tank secured within the remote unit where the air and cleaning solution are separated. The blower removes the air from the recovery tank and directs the same back to a dry air manifold secured to the hand-held applicator. As the air moves from the recovery tank to the dry air manifold, the upholstery is heated and dryed. Once inside the dry air manifold the air is directed onto the upholstery through an outlet disposed above and adjacent to the vacuum head for drying the upholstery. Thus an area of upholstery is cleaned and dryed in a single swath of the hand-held applicator.
