Abstract
A surface cleaning apparatus has a base configured to be moved across a surface to be cleaned, a fluid delivery system, and a fluid recovery system with a suction nozzle assembly defining a fluid flow path. A squeegee is provided in the suction nozzle assembly and is mounted within the fluid flow path to slide forwardly and rearwardly within the suction nozzle assembly as the base is moved rearwardly and forwardly, respectively.
Claims31
A surface cleaning apparatus, comprising:
- a housing including an upright handle assembly and a base mounted to the handle assembly and adapted for movement across a surface to be cleaned;
- a fluid delivery system provided on the housing, comprising:
- a fluid supply chamber;
- and
- a fluid dispenser in fluid communication with the fluid supply chamber;
- and
- a fluid recovery system provided on the housing, comprising:
- a suction nozzle assembly provided on the base and adapted to be adjacent the surface to be cleaned as the base moves across the surface to be cleaned,
- and comprising a forward wall and a rearward wall spaced from the forward wall to form a fluid flow path therebetween;
- a recovery chamber;
- a vacuum source in fluid communication with the suction nozzle assembly to draw the fluid from the surface to be cleaned through the fluid flow path and deposit the fluid in the recovery chamber;
- and
- a squeegee provided in the suction nozzle assembly and adapted to contact the surface to be cleaned as the base moves across the surface to be cleaned, wherein the squeegee is mounted within the fluid flow path to slide forwardly and rearwardly within the suction nozzle assembly as the base is moved rearwardly and forwardly, respectively, wherein the squeegee comprises a cylindrical squeegee mounted within the fluid flow path.
