Abstract
A combination cleaning solution recovery tank and air-liquid separator for use in a carpet extractor comprises a tank and a lid engaging the tank. The lid includes a top wall and a bottom wall connected by a circumferential outer wall to form a chamber therebetween. An interior wall extends between the top wall and the bottom wall dividing the chamber into a first plenum and a second plenum. The first plenum has an inlet for receiving liquid-laden working air and an exit in fluid communication with the tank. The second plenum has an inlet in fluid communication with the tank and an exit for discharging working air from the second plenum. A baffle assembly is removably mounted in said tank.
