Surface cleaner including pump cooling

A surface cleaner comprising:

• a housing;
• a suction nozzle coupled to the housing;
• a recovery tank in fluid communication with the suction nozzle, the recovery tank disposed on the housing in a recovery tank operating position;
• a suction source disposed in the housing, the suction source in fluid communication with the suction nozzle and the recovery tank, the suction source configured to draw fluid and debris through the suction nozzle and into the recovery tank when the recovery tank is in the recovery tank operating position;
• a supply tank configured to store a cleaning fluid, the supply tank including a first recess and a second recess, the supply tank disposed on the housing in a supply tank operating position;
• a distributor in fluid communication with the supply tank when the supply tank is in the supply tank operating position, the distributor configured to dispense the cleaning fluid from the supply tank onto a surface being cleaned;
• a pump in fluid communication with the supply tank and the distributor, the pump operable to pump the cleaning fluid in a direction from the supply tank to the distributor;
• and
• a pump housing disposed within the housing, the pump disposed in the pump housing and the pump housing including a cooling air inlet and a cooling air outlet in fluid communication with the suction source, such that air is configured to enter the pump housing through the cooling air inlet, pass over the pump to cool the pump, and then exit the pump housing through the cooling air outlet, and
• wherein the housing further includes a first tank guide projection that is received in the first recess of the supply tank when the supply tank is in the supply tank operating position, the first tank guide projection including a cooling air inlet in fluid communication with the cooling air inlet of the pump housing, and
• wherein the housing further includes a second tank guide projection that is received in the second recess of the supply tank when the supply tank is in the supply tank operating position, the second tank guide projection forms a cooling air flow path between the cooling air inlet of the first tank guide and the cooling air inlet of the pump housing.
