Abstract
A portable extractor apparatus is shown which includes a wheel mounted base having a solution tank for dispensing and recovering cleaning solution. A cleaning wand is connected to the solution tank and has a head which contacts the surface to the cleaned for dispensing and recovering cleaning solution. A fluid pump circulates cleaning solution in a path between the solution tank and the cleaning head. A vacuum motor provides a vacuum source for the cleaning head for suctioning the surface being cleaned and has an exhaust fan for exhausting excess heat created by the operation of the vacuum motor. A fluid operated heat exchanger is mounted in the vicinity of the vacuum motor. The heat exchanger is plumbed in the circulation path of the cleaning fluid, whereby excess heat generated by the vacuum motor is transferred to the cleaning fluid being applied from the cleaning head onto the surface to be cleaned. The cleaning head can also be integrally mounted on the wheel mounted base.
