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.

Handle assembly for a cleaning apparatus

An upright vacuum cleaner is provided having a suction nozzle height adjustment arrangement controlled by a rotary mode control member located on the upper housing. The rotary mode control member controls a suction nozzle height adjustment motor and a rotary agitator drive disconnect arrangement. A wheel tensioner located on an idler arm is operatively connected to a cam on the suction nozzle height adjustment motor which tensions and de-tensions the agitator drive belt to control the rotary agitator. The rotary mode control member could have discrete settings for the various floor surfaces to be cleaned including bare floors and carpet of varying pile heights. Alternately, the rotary mode control member could be variable so that an infinite number of suction nozzle height settings can be selected.

A carpet cleaning machine for uniformly spreading a dry carpet cleaning powder onto a surface and working the dry carpet cleaning powder into the surface. The cleaning machine includes base having a hopper integrally formed therein, distribution slots on the bottom of the hopper, a rotary powder agitator inside the hopper, wheels for supporting the base over a floor surface and for rotating the powder agitator, a metering gate for controlling the dispensing of the dry carpet cleaning powder, a trigger located on the cleaner handle for controlling the metering gate, and a plurality of motor driven vertical axis rotary brushes for working the dry carpet cleaning powder into the carpet. The dry carpet cleaning powder is dispensed onto the carpet and allowed to sit for a short period of time to allow the dry carpet cleaning powder to absorb the dirt contained in the carpet. After the dry carpet cleaning powder has dried and absorbed dirt, the dry carpet cleaning powder and dirt are vacuumed from the carpet with an ordinary vacuum.

Dry powder spreader

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.

Recovery tank for a cleaning apparatus

A floor cleaning device having a base assembly for movement along a cleaning surface is provided. The base assembly comprises a brush assembly for engaging the surface of the floor being cleaned removably mounted to a base part. A nozzle assembly is removably mounted to the base part such that the nozzle assembly is positioned adjacent to the brush assembly to prevent the brush assembly from disengaging from the base part.

Brush assembly for a floor cleaning unit

A recovery tank is provided for a floor cleaning unit. The recovery tank includes an inlet opening and a duct fluidly connected to the inlet. The duct extends horizontally within the tank adjacent a side wall the recovery tank for directing air and liquid from the inlet opening in two opposing directions. A lid covers the tank and has an outlet opening for directing air out of the recovery tank. A pair of shields depends downwardly from the lid and extends from the duct to the side wall of the recovery tank. The outlet opening of the lid is located between the shields such that the shields prevent liquid from coming out of the duct and entering the outlet opening of the lid.
