A liquid extraction surface cleaning apparatus has an upwardly opening recovery tank and a top for the tank which contains a suction fan having a suction inlet opening into the tank. A wand connects to a source of cleaning liquid and has a dispensing and pickup head that deposits liquid on the surface to be cleaned in response to actuation of a control valve and picks up dirty fluid. A water and air separator has an arcuate surface transverse of the flow path of the air and spent liquid which gently separates them into separate streams by diverting the cleaning liquid laterally away from the air stream. A shutoff valve for preventing recovered liquid in the tank from entering the suction fan is mounted in the recovery tank rather than to the suction inlet to avoid dripping dirty liquid onto the floor when the cover is removed. A handle is mounted internal the tank and additionally serves to strengthen the tank sidewalls.
