US Patent 8635740 Flow control of an extractor cleaning machine

An extractor cleaning machine includes a base or foot having a distribution nozzle and a suction nozzle. A suction source fluidly communicates with the suction nozzle, and a distributor fluidly communicates with the distribution nozzle. The distributor delivers cleaning fluid to the distribution nozzle and has first and second non-zero operating speeds. A first manually operable actuator associated with the distributor changes the distributor from the first operating speed to the second operating speed. The distributor also includes a third non-zero operating speed, and a second manually operable actuator associated with the distributor changes the distributor from the second operating speed to the third operating speed.
