Abstract: An extractor includes a fluid recovery system including a suction nozzle, a recovery tank assembly, and a suction source having an inlet fluidly connected to the recovery tank assembly and the suction nozzle through an air conduit and adapted to draw liquid through the suction nozzle and deposit the liquid in the recovery tank assembly. The extractor includes a body provided with the air conduit for movement between a first position wherein suction is unreduced and a second position wherein suction is reduced. The extractor includes a fluid delivery system including a solution supply tank assembly, a fluid distributor, and a conduit for depositing fluid onto a surface. The extractor includes a hydraulic connector operably coupled to the body and adapted to move the body between the first and second positions.

Abstract: A method of cleaning a surface with an extractor having a fluid supply system and a fluid recovery system includes applying a cleaning fluid to a surface, applying suction to the surface to remove the applied cleaning fluid from the surface, and selectively interrupting the suction to the surface for a selected time to increase dwell time of the cleaning fluid on the surface.
