US Classification:

318034000, 318254000

Abstract:

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.

Kenneth Symensma - Canton OH, US

International Classification:

A47L011/30

US Classification:

015320000

Abstract:

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.

Abstract:

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. The handle includes a lower portion and an upper portion pivotally connected to the lower portion and pivoted between an upper position for use and a lower position for storage. A solution tank for supplying a flow of cleaning solution to the surface is removably mounted to one of the base portion and the handle. A recovery tank removably mounted to one of the base portion and the handle and is in fluid communication with a suction nozzle secured to said 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, wherein one of the solution tank and the recovery tank is removably mounted to the handle.
