ABSTRACT:
A portable surface cleaning apparatus comprises a fluid dispensing system including at least one fluid supply tank, a dispensing nozzle for applying a cleaning fluid to a surface to be cleaned, and a block heater for heating the fluid to be applied to the surface to be cleaned to a temperature less than boiling; a fluid recovery tank for holding recovered fluid; a suction nozzle; a working air conduit extending between the recovery tank and the suction nozzle; and 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 into the recovery tank to thereby recover fluid from the surface to be cleaned.
