An improved carpet extractor is provided having powered brushes for scrubbing cleaning solution on a floor surface and a floor nozzle for extracting soiled cleaning solution from the floor surface in a floor cleaning mode. The extractor may be converted from the floor cleaning mode to an above the floor cleaning mode for cleaning upholstery, stairs, spots on carpet, or the like, with an attached hand held wand having a cleaning solution applicator and an upholstery and stair cleaning nozzle. A pair of motors are provided, one for driving the floor scrubbing brushes when in the floor cleaning mode and one for driving a cleaning solution supply pump and providing pressurized cleaning solution to the wand in the above floor cleaning mode. An automatic conversion mechanism is provided for automatically energizing and de-energizing the motors depending upon the operative position of the handle portion of the extractor.
