Abstract: A carpet cleaning system having a single, hand-held wand and mounted on it, a pre-spray canister, a venturi tee fluidly connected thereto, and valves for directing pressurized hot water into first and/or second flow streams. Downstream of a flow-splitting tee, a single valve regulates the first flow stream; and a pair of valves, sandwiching the venturi tee, regulate the second flow stream. This pair also controls cleaning solution discharging from the pre-spray canister via the venturi tee. Positioned at the operator's fingertips are the single valve's handle and a bar for moving the paired valves' handles simultaneously, thus allowing one to momentarily turn on or off either flow stream or adjust a mix thereof. Importantly, without interrupting any steam cleaning then in progress, one can immediately reapply the cleaning solution to a stain and, as a consequence, substantially upgrade the quality of the finished carpet cleaning job.
