Patent number: 7363681Abstract: A cleaning apparatus for cleaning a surface in which cleaning solution is dispensed to the surface and substantially simultaneously extracted along with the dirt on the surface in a continuous operation is provided. The cleaning apparatus includes a base portion for movement along the surface and a handle pivotally connected to the base portion. A solution tank for supplying a flow of cleaning solution to the surface is removably mounted to one of the base portion and handle. A recovery tank is removably mounted to the handle. A suction nozzle is secured to the base portion. A suction source is located downstream of the recovery tank in fluid communication with the suction nozzle for generating suction to draw dirt and liquid through the suction nozzle and into the recovery tank. A suction conduit is fluidly connected between the recovery tank and the suction source.Type: GrantFiled: June 25, 2004Date of Patent: April 29, 2008Assignee: Healthy Gain Investments Ltd.Inventors: Michael A.

Patent number: 7362064Abstract: A cleaner for cleaning a surface comprises a floor-engaging portion for moving along the surface. A magnet and a hall effect sensor located in the cleaner handle generates a control signal. The control signal is provided to a control circuit which controls one or more operational features of the cleaner. One such operational features includes at least one pump for mixing and distributing cleaning solution to the surface. In an alternate embodiment, the control circuit controls an electric motor for propelling the cleaner over the surface.Type: GrantFiled: September 15, 2004Date of Patent: April 22, 2008Inventors: Donald A. Coates, Robert W. Bauman, Michael A. Durbin, Evan A. Gordon, Adam C. Sclafani, Aaron P. Tondra, William H. Theiss, Jr., Timothy T. Hertrick, David A. Bradshaw, Edgar A. Maurer, Wilbur J. Kellum

Patent number: 7340797Abstract: The cleaning apparatus includes a base portion for movement along the surface and a handle pivotally connected to the base portion. A recovery tank is removably mounted to the handle and has a front end. A lid covers the recovery tank and has an inlet opening for directing dirt and liquid into the recovery tank and an outlet opening located at the front end of the recovery tank. A suction nozzle is secured to the base portion and fluidly communicates with the inlet opening of the lid. A suction source fluidly communicates with the outlet opening for drawing dirt and liquid from the surface through the suction nozzle and into the recovery tank. A partition device is positioned between the outlet opening and the inlet opening and extends down within the recovery tank a sufficient distance to prevent the liquid from flowing from the inlet opening to the outlet opening.Type: GrantFiled: June 25, 2004Date of Patent: March 11, 2008Assignee: The Hoover CompanyInventors: William H. Theiss, Jr., Jonathan E. Fawcett, Kenneth H. Cooper, Steven W. Kegg, Kenneth L. Symensma

Patent number: 7331082Abstract: A cleaning apparatus for cleaning a surface in which cleaning solution is dispensed to the surface and substantially simultaneously extracted along with the dirt on the surface in a continuous operation is provided. The cleaning apparatus includes a base portion for movement along the surface and a handle pivotally connected to the base portion. A solution tank for supplying a flow of cleaning solution to the surface is removably mounted to a side of the handle. A recovery tank is removably mounted to the opposite side of the handle. A suction nozzle is secured to the base portion. A suction source is in fluid communication with the suction nozzle for generating suction to draw dirt and liquid through the suction nozzle and into the recovery tank.Type: GrantFiled: June 25, 2004Date of Patent: February 19, 2008Assignee: The Hoover CompanyInventors: Timothy T. Hertrick, David J. Boles, Michael A. Durbin, Jonathan E. Fawcett, Gary M. Johns, Charles A. Lang, Richard S. Parr, Ryan S. Steiner, William H. Theiss, Jr., Donald R. Wright, Paul E. Volkmann

Patent number: 7299521Abstract: A floor-scrubbing machine is provided having a main body and a cleaning fluid delivery system. At least one rotatable brush having a brush body and bristles extending from the brush body is included. The brush is carried by the main body whereby the bristles of the brush engage the floor being scrubbed. A fluid distributor is provided to distribute cleaning fluid supplied to the fluid distributor to the brush. The brush defines a recess having a sidewall and at least one opening formed in the sidewall for distributing the cleaning solution radially outward.Type: GrantFiled: November 4, 2002Date of Patent: November 27, 2007Assignee: The Hoover CompanyInventors: William H. Theiss, Jr., Robert W. Bauman, Dale L. Buxton, David B. Rennecker
