Publication number: 20030110588Abstract: A carpet extractor includes a solution distributor, such as a spray bar 90, which delivers cleaning solution to a floor surface. A housing 10 selectively receives a recovery tank 22 for collecting dirty cleaning solution from the floor. A first tank 14 for concentrated cleaning fluid and a second tank 15 for clean water supply cleaning fluid and water to a reciprocating pump 420 through first and second fluid lines 412, 410. The pump includes a piston 428, which reciprocates between first and second ends of a cylindrical bore 430. A fluid line 432 interconnects the first and second fluid lines. As the pump reciprocates, a portion of the water is drawn into the interconnecting line during a downward stroke, where it mixes with the entering cleaning solution. As the pump moves on its upward stroke, the mixture is drawn back into the water line and is pushed onward by the pump toward the spray bar with each successive downward stroke.Type: ApplicationFiled: January 31, 2003Publication date: June 19, 2003Applicant: Royal Appliance Mfg. Co.Inventors: Terry L. Zahuranec, Brett Latimer, Robert A. Salo, Mark E. Cipolla, Wallace D. Tiller, Jeffrey M. Kalman, Craig M. Saunders

Patent number: 6536071Abstract: A carpet extractor includes a base assembly 1 including a housing 10 which selectively receives a recovery tank 22 for collecting dirty cleaning fluid. A first supply tank 14 for concentrated cleaning fluid and a second supply tank 15 for clean water are mounted on an inverted Y-shaped handle assembly 12. The handle assembly includes a central member 334 with a hand grip 336 at its upper end and two splayed leg members 338, 342, 340, 344, which define a triangular shaped gap therebetween. The two tanks are removably mounted in the gap. The cleaning fluid tank is supported on a shelf 346, which spans the gap between the leg members. The water tank is pivotally mounted on two projections 374 on the leg members to allow for easy removal and replacement on the handle. The arrangement of tanks in the gap allows for large capacity tanks, a well-balanced handle, ease of removal of the recovery tank without the need for removing either of the two supply tanks, and ease of refill of the supply tanks.Type: GrantFiled: January 12, 2001Date of Patent: March 25, 2003Assignee: Royal Appliance Mfg. Co.Inventors: Terry L. Zahuranec, Brett Latimer, Robert A. Salo, Mark E. Cipolla, Wallace D. Tiller, Jr., Jeffrey M. Kalman, Craig M. Saunders

Patent number: 6533871Abstract: A carpet extractor includes a base assembly 1 including a housing 10 which selectively receives a recovery tank 22 for collecting dirty cleaning fluid. A nozzle assembly 67 is mounted to the base housing and provides a fluid flowpath 182 for dirty cleaning fluid from the floor surface to the recovery tank. The nozzle assembly is pivotable from a first position, in which the fluid flowpath communicates with the recovery tank, to a second position, in which the nozzle assembly is spaced from the recovery tank to allow the recovery tank to be removed from the base housing. A second flowpath 138 is formed on the recovery tank between the tank and a nozzle plate 136. The flowpaths have openings 218, 140, respectively, at their lower ends, which are located either side of two longitudinally spaced brushrolls 60, 62. A flap valve 474 selectively closes both flowpaths during above floor cleaning.Type: GrantFiled: January 12, 2001Date of Patent: March 18, 2003Assignee: Royal Appliance Mfg. Co.Inventors: Terry L. Zahuranec, Brett Latimer, Robert A. Salo, Mark E. Cipolla, Wallace D. Tiller, Jr., Jeffrey M. Kalman, Craig M. Saunders

Publication number: 20030037406Abstract: A vacuum cleaner includes a first housing defining a cyclonic airflow chamber and a second housing defining a main suction opening that is in communication with an inlet of the cyclonic chamber. A suction source has a suction airstream inlet in communication with an outlet of the cyclonic chamber, and establishes a suction airstream that enters said main suction opening, passes through said cyclonic chamber, and passes to an outlet of said suction source. A substantial portion of particulates entrained in the suction airstream are separated therefrom when said suction airstream moves in a cyclonic fashion through the cyclonic chamber.Type: ApplicationFiled: October 15, 2002Publication date: February 27, 2003Applicant: Royal Appliance Mfg.

Publication number: 20020026775Abstract: A bagless canister vacuum cleaner includes a selectively removable dirt cup, and an airstream flows rotationally through the dirt cup between an interior wall of the dirt cup and a filter assembly selectively mounted in the dirt cup so that entrained contaminants are separated from the airstream flowing through the dirt cup and collected by the dirt cup. The filter lies substantially parallel to the support surface on which the vacuum cleaner is supported. A cover member is connected to the main housing, and the cover member is selectively movable to and held in an operative position in covering relation with an open first end of a dirt cup. The main housing defines a base conformed to self-support the main housing on a support surface with the dirt cup arranged with its open first end at a higher elevation than its closed second end. The removable dirt cup includes a handle adapted for being held by a user, and the dirt cup defines or includes a spout to facilitate emptying dirt therefrom.Type: ApplicationFiled: August 31, 2001Publication date: March 7, 2002Applicant: ROYAL APPLIANCE MFG.

Patent number: 6341404Abstract: An upright vacuum cleaner includes an upright housing section and a nozzle base section. A cyclonic airflow dirt and dust separating chamber is defined in the upright housing section. A suction source pulls air and entrained dirt, dust, and other contaminants through a main suction opening formed in the underside of the nozzle base section and into the cyclonic airflow chamber. The cyclonic airflow chamber causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container that defines the chamber. A main filter element filters residual contaminants from the suction airstream between the chamber and the suction source. An exhaust filter housing includes an airstream suction duct in fluid communication with an outlet of the airflow chamber and an inlet of the suction source. An outlet of the suction source is in fluid communication with an exhaust plenum of the exhaust filter housing.Type: GrantFiled: January 13, 2000Date of Patent: January 29, 2002Assignee: Royal Appliance Mfg.
