Abstract: A novel upright carpet cleaning extractor is disclosed which may be conveniently converted from the floor cleaning mode to the upholstery and/or stair cleaning mode. The overall configuration and operation of the extractor is similar to that of a typical upright vacuum cleaner and may be operated in the forward or reverse direction similar to a typical upright vacuum cleaner. When in the floor cleaning mode, cleaning solution is supplied to a solution distributor by gravity flow. However, when converted to the upholstery cleaning mode an auxiliary, air turbine driven cleaning solution pump is automatically energized for supplying pressurized cleaning solution to an upholstery or stair cleaning nozzle.

Abstract: A self-propelled vacuum cleaner is provided having an upper handle portion and a carriage pivotally mounted to a lower end of the handle portion for pivotal motion relative the handle portion about a horizontally extending carriage axis. A transmission drivingly connected to at least one drive wheel mounted on the carriage, whereby the at least one drive wheel propels the vacuum cleaner over a floor surface. A nozzle body pivotally mounted to the carriage for pivotal motion relative the carriage about a generally horizontally extending nozzle axis, the nozzle body having a downward facing suction opening. The nozzle axis being generally horizontally offset from the carriage axis.

Abstract: A self propelled upright vacuum cleaner is provided that has at least one drive wheel, a transmission for selectively driving the drive wheel in forward and reverse and propelling the cleaner in forward and reverse over a floor. A bag housing pivotally connected to the floor engaging portion. An electric power switch located adjacent to a top of the bag housing. A control link extending from the transmission and up the bag housing, with a top end of the control link being located adjacent to the top of the bag housing. An upper handle assembly having a hand grip reciprocally mounted thereon and a power switch button mounted thereon. The lower end of the upper handle assembly is adapted for connection to the top of the bag housing, such that the upper end of the control link and the hand grip are automatically interconnected when the upper handle assembly is attached to the bag housing.

Abstract: 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.

Abstract: A self-propelled upright vacuum cleaner is provided having a lower portion and an upright handle portion pivotally attached to the floor engaging portion for a pivotal motion between an upright storage position and a pivotal operating position. A drive wheel mounted to the floor engaging portion. A transmission operatively connected to the drive wheel and a motor drivingly connected to the transmission for driving the drive wheel in forward and reverse. A transmission actuator arm pivotally mounted to the floor engaging portion adjacent to the transmission for pivotal motion about a pivot axis located at a central portion of the actuator arm. A manual actuator mounted to the handle portion.

Abstract: The present invention teaches a combined air/liquid separator and recovery tank for use on a hot water carpet extractor. The combined tank and separator are particularly suited for an upright style of carpet extractor and features easy removal for emptying the recovery tank at a site remote from the extractor.

Abstract: A novel upright, hot water carpet cleaning extractor is disclosed. The overall configuration and operation of the extractor is similar to that of a typical upright vacuum cleaner and may be similarly operated in both the forward and reverse direction. The herein taught extractor comprises a base frame including the floor suction nozzle, suction fan, cleaning solution distributor, and a removable combination air/liquid separator and recovery tank. A manipulative push-pull handle is pivotly attached to the base frame having a removable cleaning solution supply tank supported thereon. The herein taught upright extractor is easily stored, self contained, easy to operate and requiring minimal effort by the operator.
