1. Carpet cleaning apparatus comprising, in combination:
- a cleaning wand including a vacuum head having a vacuum head front and a vacuum head rear for applying a vacuum to a carpet and defining a vacuum head interior and a vacuum head inlet communicating within said vacuum head interior and an elongated member connected to said vacuum head and leading to a vacuum source, said elongated member defining a passageway in communication with said vacuum head interior for applying a vacuum to said vacuum head interior and transporting material removed from a carpet by said vacuum head;
a first manually graspable handle connected to said elongated member at a first location on said elongated member;
a second manually graspable handle connected to said elongated member at a second location on said elongated member;
a front spray nozzle located adjacent to the vacuum head at the vacuum head front and in front of the vacuum head inlet;
a rear spray nozzle located adjacent to the vacuum head at the vacuum head rear and to the rear of the vacuum head inlet; and
valve means operatively associated with said first and second manually graspable handles for selectively controlling the flow of cleaner fluid to said front and rear spray nozzles from a source of cleaner fluid, said valve means including a first fluid flow control valve operatively associated with said first manually graspable handle for receiving cleaner fluid from the source of cleaner fluid and a second fluid flow control valve operatively associated with said second manually graspable handle for receiving cleaner fluid from the source of cleaner fluid, said first fluid flow control valve controlling the flow of cleaner fluid to said front spray nozzle responsive to manipulation of said first manually graspable handle and said second fluid flow control valve controlling the flow of cleaner fluid to said rear spray nozzle responsive to manipulation of said second manually graspable handle.

Abstract
Carpet cleaning apparatus includes a cleaning wand having a vacuum head and an elongated member forming a passageway for transporting material removed from a carpet by the vacuum head. A cleaning liquid spray nozzle is located at the front of the vacuum head and another cleaning liquid spray nozzle is located at the back of the vacuum head. Two control valves are attached to the elongated member, each controlled by a separate moveable handle, allowing the operator to selectively spray in front or in back of the vacuum head as desired.
