Abstract
An extraction cleaner includes a supply tank, a recovery tank, a pump, a suction source, a base configured to support the suction source and the pump, an external hose, and a hose attachment assembly. The hose attachment assembly has a suction conduit extending from a suction inlet connected to the proximal end of the hose to a suction outlet in fluid communication with the recovery tank. The suction conduit is removable from the base with the hose. The hose attachment assembly also has a fluid coupling which is removable with the suction conduit. The fluid coupling extends from a coupling inlet in fluid communication with the pump to a coupling outlet coupled to a supply tube having one or more portions carried within the suction conduit. The proximal end of the hose is at least partially nested adjacent the base when the suction conduit is coupled to the base.
