At least a portion of the supply tank is positioned above and over the recovery tank in a direction normal to a surface to be cleaned when the extractor handle is in an upright storage position. The supply tank is in fluid communication with the distribution nozzle to supply cleaning fluid to the distribution nozzle. The extractor cleaning machine is liftable by the recovery tank handle when the extractor handle is in the upright storage position.
