The herein disclosed invention relates to an improved carpet extractor having powered brushes for scrubbing a floor surface and which may be converted to an above the floor mode for upholstery cleaning or the like. A pair of air driven turbines are disclosed, one for driving the floor scrubbing brushes when in the floor cleaning mode and one for driving a cleaning solution supply pump when in the above floor cleaning mode. A unique linkage mechanism is taught whereby only one turbine or the other is energized depending upon the cleaning mode selected by the operator.

[ We claim:] [17.] A carpet extractor comprising:a cleaning liquid reservoir for providing a supply of cleaning liquid;a cleaning liquid distributor in selective fluid communication with said cleaning liquid reservoir for selectively distributing the cleaning liquid onto a floor surface;a powered brush system having at least one brush for scrubbing the distributed cleaning solution on the floor surface;a motor/fan assembly;a floor nozzle in selective fluid communication with said motor/fan assembly for extracting the distributed and scrubbed cleaning solution from the floor surface;a liquid pump in fluid communication with said cleaning liquid reservoir for providing a source of pressurized cleaning liquid;an above-floor cleaning tool having a cleaning liquid applicator in selective fluid communication with said liquid pump for selectively applying cleaning liquid to an above-floor surface and an above-floor nozzle in selective fluid communication with said motor/fan assembly for extracting the applied cleaning liquid from the above-floor surface; anda conversion mechanism operatively connected to said powered brush system and operatively connected to said liquid pump for selectivelyactivating said powered brush system and de-activating said liquid pump placing said extractor in a floor cleaning mode; andactivating said liquid pump and de-activating said powered brush system placing said extractor in an above-floor cleaning mode, wherein at least one of said powered brush system and said liquid pump is driven by an air powered turbine that is in fluid communication with said motor/fan assembly whereby said motor/fan assembly creates a flow of air through said turbine for driving said turbine.
