Extraction cleaning with heating

A unitary portable surface cleaning apparatus, comprising:

• 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 at a predetermined rate;
• 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 heater exchanger, including an electrical heating element, associated with the fluid supply conduit for heating the cleaning fluid in the fluid supply conduit to be applied to the surface to be cleaned and a heat storage body for storing heat energy from the electrical heating element;
• wherein the electrical heating element is adapted to continuously supply at least about 500 watts of power from an ordinary 120 volt line.
