摘要:
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. A suction shut off device is operatively connected to the suction source to shut shutoff suction through at least a portion of the suction conduit upon the handle being pivoted down a predetermined distance to a first position.
