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.

2. A carpet extractor comprising:
-
a) a main body, said main body including cleaning solution distribution means for applying cleaning solution to a floor surface, a suction nozzle, suction means fluidly communicating with said suction nozzle for drawing working air with entrained cleaning solution and other debris into said nozzle, fluid recovery means interposed between said suction nozzle and said suction means for separating and storing said cleaning solution and other debris from said working air, b) conversion means for converting said extractor from the floor cleaning mode to above the floor cleaning mode said conversion means including a combined hand held suction nozzle and cleaning solution distribution means, c) a cleaning solution pump for supplying, under pressure, cleaning solution to said hand held distribution means, an air turbine drivingly connected to said pump, said air turbine fluidly communicating with said suction means whereby ambient air is drawn through said turbine thereby driving said cleaning solution pump, and d) means for selectively opening or closing the air inlet port of said air turbine whereby said air turbine and said solution pump may be energized at will. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 24, 25)

10. A convertible carpet and upholstery cleaner having a floor cleaning mode and a converted upholstery cleaning mode comprising:
-
a) a base frame, said base frame including vacuum producing means, cleaning solution distribution means for applying cleaning solution upon a floor surface being cleaned, and a floor vacuuming nozzle means for removing at least a portion of said cleaning solution from said floor surface; b) a cleaning solution recovery tank removably supported upon said base frame, conduit means between said floor nozzle means and said recovery tank for fluid communication therebetween, conversion means for converting said cleaner from the floor cleaning mode to said upholstery cleaning mode; c) fluid separation means, associated with said recovery tank whereby liquid and debris carried by said working air is separated from said working air and collected in said recovery tank; d) upright handle means pivotally connected to said base frame whereby the base frame may be manually manipulated in a forward and reverse directions, said handle means including a cleaning solution supply tank removably supported thereupon; e) cleaning solution supply means whereby cleaning solution may be selectively conveyed from said supply tank to said floor cleaning solution distribution means; f) auxiliary pump means for alternatively supplying cleaning solution to said upholstery cleaning apparatus; g) conduit means fluidly communicating between said supply tank and the inlet port of said pump means whereby cleaning solution may be withdrawn from said supply tank. - View Dependent Claims (11, 12, 13, 14, 15, 16, 23)

17. In a carpet extractor having means for applying cleaning solution to a floor surface and vacuuming said solution from said floor surface, the improvement comprising:
- means for converting said extractor from the floor cleaning mode to an upholstery cleaning mode;
said conversion means including solution supply pump means for supplying cleaning solution to an associated upholstery cleaning accessory;
said pump means including means for activating said pump means when said extractor is converted to the upholstery cleaning mode. - View Dependent Claims (18, 19, 20, 21)
- means for converting said extractor from the floor cleaning mode to an upholstery cleaning mode;
- 26. In a vacuum cleaner usable as an extractor, wherein said vacuum cleaner includes a vacuum producing source, means for separating and recovering liquid from vacuumed air, nozzle means for vacuuming the surface to be cleaned, a flexible hose fluidly connecting said nozzle means with said liquid recovery means, a cleaning solution supply tank, an applicator for applying cleaning solution to the surface being cleaned, an air turbine, a cleaning solution supply pump, drivingly connected to said air turbine, said air turbine having an intake port and a discharge port said discharge port fluidly communicating with said vacuum source whereby air may be drawn into said intake port and through said air turbine, a cleaning solution supply tube fluidly connecting said cleaning solution supply pump and said cleaning solution applicator, the improvement comprising a housing containing therein at least the said air turbine driven solution supply pump, an opening in said housing having a hinged door whereby said opening may be selectively opened or closed, said air turbine intake port aligned with said opening such that air may enter said intake port through said opening, sealing means between said door and said intake port whereby said door, when in the closed position, prevents the flow of air into said turbine intake port thereby de-energizing said air turbine.
