Abstract
A surface cleaning apparatus comprises an accessory hose mounted to an upright handle and a recovery tank mounted to a base. An accessory working air path is formed between the accessory hose and the recovery tank when the upright handle is in an upright position and is separated when the handle is tilted from the upright position. The upright handle and the base can include couplings that are in register when the upright handle is in the upright position to form the accessory working air path.
Claims20
A surface cleaning apparatus comprising:
- a housing including a base and an upright handle pivotally mounted to the base for manipulation of the base along a surface to be cleaned and for movement between an upright position and an inclined position;
- a recovery tank mounted to the base;
- a hose having a first end mounted to the handle and a second end adapted for connection to an accessory cleaning tool;
- a first coupling on the handle in fluid communication with the first end of the hose;
- a second coupling on the base in fluid communication with the recovery tank and in registry with the first coupling when the handle is in the upright position and out of registry with the first coupling when the handle is in the inclined position;
- and
- a vacuum source fluidly coupled with the recovery tank and fluidly coupled to the hose when the handle is in the upright position with the first coupling in registry with the second coupling to draw dirt through the hose into the recovery tank.
