Abstract
An embodiment of this invention is an adjustable wand for a carpet cleaning apparatus wherein the upper tube telescopes within a lower tube and allows lengthening of the wand. The lower nozzle is adjustable in that it allows rotation about the wand axis and allows removal of the nozzle. The preferred means for adjustment is a cam lock mechanism that tightens an adjustment clamp around the wand upper tube or nozzle neck.
