Abstract:

An elongated tubular handle and support member connectable at its upper end with a vacuum hose and at its lower end with a vacuum head having a perpendicularly extending, elongated suction opening and including a pair of spray nozzles fixed with respect to the vacuum head and adapted to spray, respectively and selectively, either carpet cleaning fluid or carpet dyeing fluid behind the vacuum head, supports along the length thereof an open-topped container for removably receiving a liquid dye container. The tubular handle and support member also has attached thereto a control valve assembly for directing fluid under pressure to either of said spray nozzles, selectively, from a single remote source. The means supplying pressurized fluid to one of the spray nozzles includes a flexible conduit series-connected in which is a venturi member having a venturi orifice communicating through a control valve with the dye container for withdrawing dye into the flow path of the pressurized fluid supply to the dye spraying nozzle.
