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. A solution tank for supplying a flow of cleaning solution to the surface is removably mounted to the handle. A recovery tank is removably mounted to the handle. A suction nozzle is secured to the base portion and in fluid communication with the recovery tank. 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. A cost effective, easy to operate, and convenient mounting arrangement is provided for mounting the recovery tank to the handle.
