ABSTRACT:
A portable surface cleaning apparatus comprises a fluid dispensing system including at least one fluid supply tank, a dispensing nozzle connected to the fluid supply tank through a fluid supply conduit for applying a cleaning fluid to a surface to be cleaned, a fluid recovery tank for holding recovered fluid, a suction nozzle, a working air conduit extending between the recovery tank and the suction nozzle, a vacuum source in fluid communication with the recovery tank for generating a flow of working air from the suction nozzle through the working air conduit and to the recovery tank to thereby recover fluid from the surface to be cleaned through the suction nozzle and working air conduit and into the recovery tank, and a power drive mechanism for selectively propelling the portable cleaning apparatus over the surface to be cleaned
