Abstract: A rug and carpet cleaning apparatus of the type in which a housing is shifted along the floor and is connected to a suction chamber while having rotary brush, carpet-shampoo, massager, and like rotary units which are selectively to act upon the carpet depending upon the function or operation to be carried out. According to the invention, at least two such units are provided on opposite sides of the fulcrum or pivot of a rocker or teeter which is controlled, e.g. by a lever and cable arrangement, to selectively bring one or the other unit into action depending upon the tilt imparted to the rocker. Both units can be continuously coupled to the drive motor which can also be mounted on the rocker.

Abstract: A new and improved home-commercial floor covering vacuum cleaning and liquid cleaning apparatus employing a rotating beater disposed within a vacuum-liquid cleaning chamber. The beater vibrates the floor covering by striking the flooring surface to agitate the dirt which is then moved by a vacuum system into a removable collecting chamber. When the dirt laden air enters the liquid collecting chamber of the apparatus, the dirt impinges on the surface of the collecting liquid and is thereby deposited in the liquid while the dirt-free air is again moved through the blower. The blower exit provides a stream of air into the vacuum-liquid cleaning chamber to pick up additional dirt. A quantity of foam-type cleaning solution is available from a container for periodical release into the stream of air exiting the blower to provide foam on the floor surface adjacent the beater. The foam is picked up by the vacuum system adjacent the rotating beaters to remove surface soil and stains.

Abstract: A brush-beater assembly for a vacuum cleaner comprises a hollow cylinder having outwardly extending projections formed in the material thereof, and slots diametrically opposed to the projections for receiving brush assemblies. The projections may be formed pneumatically or hydraulically in the cylinder, during the production thereof. An additional projection is provided in front of the brush assemblies.

Abstract: The invention provides an agitator having a beater bar and brush configuration in which the brush is closely mounted relative to the beater bar so as to receive reinforcement from it during the cleaning operation so as to have a kinetic action.

Abstract: A rapid-rotation beater or soil-loosening roller for wet or dry carpet-cleaning apparatus which has a circular axial profile and a plurality of inclined angular projections defining between them annular grooves having widths of several millimeters. The roller is formed unitarily or at least in part of a shape-retentive (rigid) material and the grooves between projections lie along a cylindrical surface.

Abstract: A vacuum cleaner is provided with a suction nozzle and a cylindrical rotary brush. The brush includes a plurality of generally longitudinally extending rows of uniform bristle tufts. Alternate tufts in alternate rows are spaced at about twice the distance as the remaining more closely spaced tufts and prepare the carpet for sweeping by the latter.PRIOR ART OF INTERESTU.S. Pat.

Abstract: A machine for cleaning a surface is provided. The machine includes a forward drum brush unit designed primarily for sweeping and a rear disc brush unit designed primarily for scrubbing. Squeegees are located behind the disc brushes. Cleaning solution is supplied between the drum brush and the disc brushes and is directed toward the drum brush to achieve a wet sweeping action thereby. The disc brushes are mounted for movement toward and away from the surface to be cleaned and are engagable with the surface under controllable pressure. The drum brush is mounted on a separate frame and is engagable by the disc brush unit so that it can be raised for transportation purposes when the disc brush unit is raised. The squeegees can be raised independently of the brushes.
