  • Patent number: 4279057
    Abstract: Spots and stains are completely removed from wall-to-wall carpeting, upholstery fabric, and the like, by using a generally flat, hollow tool, which is inserted beneath the carpet or fabric without completely removing the latter from the floor or piece of furniture which it covers. The flat tool has a plurality of spaced perforations in its upper wall; and its interior is releasably connected by a tubular extension member to a vacuum supply which creates a localized vacuum immediately beneath the portion of the carpet that is to be cleaned. A liquid cleaning medium or solvent is then applied to the spot or stain which is located above the tool; and after it passes through the carpet or fabric it is drawn into the tool and through the extension member to the vacuum supply.
