ABSTRACT:
A self contained compact carpet soil extractor includes a vacuum tube for singularly supporting a vacuum head, nozzles through which the cleaning solution is dispensed, a pivotally mounted powered brush and motor means for driving the brush; additionally, the source of vacuum, a supply of cleaning solution under pressure and a waste tank are directly or indirectly suspended from the vacuum tube. One variant includes means for supporting a quantity of the cleaning solution upon the vacuum tube and a further variant relies upon external sources to provide vacuum and cleaning solution. Support upon the carpet for the extractor is provided by the mouth of the vacuum head, the brush and a curved spring skid; the force exerted by the brush and the depth to which the brush extends into the carpet nap is primarily a function of the bristle length with respect to the plane defined by the vacuum head mouth and the skid.
