Patent number: 4729147Abstract: A portable, self-contained pet grooming and flea removing device which includes a vacuum device for grooming, removing loose hair, dirt, dandruff and the like, which are removed through interchangeable grooming devices such as a comb, brush or the like and through a flexible hose into a disposable vacuum cleaner-type bag. In addition, the vacuum hose may be easily and quickly provided with a fitting in the form of a nozzle and the hose associated with a different fitting in the vacuum device so that a flea annihilator in the form of an electric grid is placed in operation by manipulation of a power switch so that by "peeling back" the animal's hair, location of flea infestation is easily made so that the nozzle can be placed immediately over the flea so that it is moved through the hose by vacuum and passed through the electrically charged grid thereby killing the flea which is then deposited into the disposable vacuum cleaner-type bag.Type: GrantFiled: September 12, 1986Date of Patent: March 8, 1988Inventor: Joseph M. Armbruster

Patent number: 4584736Abstract: An apparatus for cleaning surfaces has a cleaning head which is designed to bear against a surface being cleaned. The cleaning head includes a discharge nozzle which is connected with a source of flowable cleaning material and is arranged to discharge such material against the surface being cleaned. A pair of shields is disposed about the discharge nozzle. The cleaning head further includes a suction nozzle which is connected with a source of suction and serves to remove contaminated cleaning material from the surface being cleaned. A brush is disposed between the discharge nozzle and the suction nozzle and functions to scrub the surface after the cleaning material has been applied thereto. The discharge nozzle, suction nozzle and brush are surrounded by a tubular sleeve which inhibits the escape of contaminated cleaning material so that virtually all such material is recovered via the suction nozzle.Type: GrantFiled: January 25, 1984Date of Patent: April 29, 1986Inventor: Gottfried Gremminger

Patent number: 4476607Abstract: A lightweight portable vacuum cleaner and attachment nozzle are disclosed which may be readily carried by an operator to vacuum both normally accessible and normally inaccessible areas. The vacuum cleaner comprises an elbow-shaped plastic housing which encloses a filter bag and blower motor. The vacuum is carried under the arm of the operator supported from a strap that goes over the operator's shoulder. A deodorant chamber is mounted to the exhaust screen of the housing, so that exhaust from the blower motor can be used to distribute scented odor over the surface that is being cleaned. In addition, footings are mounted adjacent to the exhaust screen so that proper ventilation is assured for the blower motor. A flexible hose with suction tube is frictionally fitted into an aperture in the vacuum cleaner and thereby delivers suction to the area at which they are directed. A specific attachment nozzle is coupled to a 45.degree. coupling which is coupled to the suction tube.Type: GrantFiled: September 30, 1982Date of Patent: October 16, 1984Inventor: David Ross

Patent number: 4333205Abstract: A vacuum cleaning machine using a floor-mounted vacuum hood forming a travelling vacuum chamber with an optimum combination of suction nozzle intake means, jet stream manifold means and a mechanical soil agitator means in the form of a carpet rake, where the rake is interposed between the suction nozzle intake means and a plurality of jet streams. The jet streams are generally directed toward the tips of the teeth of the carpet rake and from there toward the intake opening of the suction nozzle means to increase the effectiveness of the suction nozzle means. A second modification of the invention shows the carpet rake replaced by a power-driven brush, and the jet stream means is a combined carpet rake and source of a plurality of jet streams directed toward the working area of the brush. An optimum design is where the compressed air that divides into a plurality of jet streams is made to pulsate so as to create a hammering action on the soil.Type: GrantFiled: November 14, 1979Date of Patent: June 8, 1982Assignee: Robert E. RobbinsInventors: James C. Woodward, Marion D. Holland
