ABSTRACT:
The present invention is a carpet cleaning wand having containers for holding cleaning solution and rinsing solution mounted thereon, a hot water line, a vacuum head and a dispensing nozzle. The hot water line includes a mixing valve for infusing cleaning or rinsing solution into hot water flowing through the hot water line. A control valve is connected between each of the solution containers and the mixing valve and allows an operator to alternately select and mix either cleaning solution or rinsing solution with hot water flowing through the hot water line so that the same may be applied to the carpet or other surface being cleaned.
