Dispensing within a liquid dispensing and suctioning system is controlled by pinching a flexible tube with a spring-biased actuator. The system includes a slidable extension for pulling the actuator to open the tube to dispense liquid to a surface to be cleaned. The system is assembled with a tubular wand of a wet/dry suctioning system.

A liquid dispensing and suctioning system, comprising: a tubular wand having a suction intake end and an exit end connectable for communicating with a remote suction source; an attachment to said wand for dispensing liquid to a surface to be cleaned and for suctioning liquid from the surface, said attachment comprising: a suction nozzle having an inlet positionable adjacent the surface to be cleaned for intake of liquid and having an outlet fitting attached to said intake end of said wand; a tank supported at said suction nozzle for containing liquid to be dispensed; said tank being closed separate from said suction nozzle; a dispenser for selectively dispensing liquid from said tank to the surface to be cleaned, said dispenser comprising a dispenser inlet communicating with said tank for receiving liquid therefrom, a dispenser outlet for delivery of liquid to the surface, and a dispenser conduit between said dispenser inlet and said dispenser outlet; said dispenser conduit having a flexible portion for being pinched to cut off liquid flow between said dispenser inlet and said dispenser outlet and said flexible portion being openable to permit flow; an actuator movable against and away from said dispenser conduit; means for biasing said actuator toward a position to pinch said dispenser conduit for preventing liquid flow from said tank through said dispenser conduit; and a manually operable extension extending from said actuator up from said dispenser to a position toward said suction intake end of said wand for being graspable by a user for moving said actuator against the bias of said biasing means to an open position to open said flexible conduit to permit dispensing of liquid through said dispenser to the surface to be cleaned.
