Abstract
A carpet extractor includes a solution distributor, such as a spray bar, which delivers cleaning solution to a floor surface. A housingselectively receives a recovery tankfor collecting dirty cleaning solution from the floor. A first tankfor concentrated cleaning fluid and a second tankfor clean water supply cleaning fluid and water to a reciprocating pumpthrough first and second fluid lines. The pump includes a piston, which reciprocates between first and second ends of a cylindrical bore. A fluid lineinterconnects the first and second fluid lines. As the pump reciprocates, a portion of the water is drawn into the interconnecting line during a downward stroke, where it mixes with the entering cleaning solution. As the pump moves on its upward stroke, the mixture is drawn back into the water line and is pushed onward by the pump toward the spray bar with each successive downward stroke.
