Abstract
A surface cleaner configured to distribute a liquid to a surface to be cleaned. The surface cleaner includes a supply tank, a fluid distributor, a suction inlet aperture, a recovery tank and a tool removably connectable to the surface cleaner and configured to direct fluid from the fluid distributor into the suction inlet aperture to rinse the suction inlet aperture.
Claims18
A surface cleaner comprising:
- a supply tank configured to store a fluid;
- a fluid distributor in fluid communication with the supply tank;
- an actuator to selectively dispense the fluid from the supply tank through the fluid distributor;
- a duct having sidewalls forming a suction inlet aperture;
- a suction source in fluid communication with the suction inlet aperture;
- a recovery tank in fluid communication with the suction inlet aperture and the suction source, the recovery tank configured to receive recovered fluid and debris drawn through the suction inlet aperture;
- a tool selectively connectable to the surface cleaner configured to direct the fluid dispensed from the supply tank to the duct for rinsing the duct, the tool having a housing forming a passageway, the passageway having
- a passageway inlet configured to receive a portion of the fluid distributor;
- and
- a passageway outlet;
- wherein the passageway outlet is positionable within the suction inlet aperture when the passageway inlet receives a portion of the fluid distributor;
- and
- wherein the passageway outlet of the tool is spaced from the duct sidewall inside the suction inlet aperture enabling airflow into the suction inlet aperture between the passageway outlet and the duct sidewall sufficient to draw dispensed fluid from the passageway into the duct when the actuator selectively dispenses fluid from the fluid dispenser into the passageway inlet.

A surface cleaner comprising:
- a suction source;
- a suction duct having a suction inlet aperture in fluid communication with the suction source;
- a supply tank configured to store a fluid;
- a fluid distributor disposed adjacent the suction inlet aperture in fluid communication with the supply tank;
- an actuator to selectively dispense the fluid from the supply tank through the fluid distributor;
- a recovery tank in fluid communication with the suction inlet aperture and the suction source, the recovery tank configured to receive recovered fluid and debris drawn through the suction airflow from the suction inlet aperture;
- a tool selectively connectable to the fluid distributor, the tool configured to direct the fluid dispensed from the supply tank to the suction duct to rinse the suction duct, the tool including a housing with
- a fluid inlet configured to receive a portion of the fluid distributor;
- and
- a fluid outlet configured to direct fluid flow from the fluid inlet to the suction inlet aperture, wherein the fluid outlet is positioned adjacent the suction inlet aperture and the tool covers less than 50% of the suction inlet.
