Claims20
A surface cleaning apparatus, comprising:
- a housing including an upright handle assembly;
- 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 comprising a forward wall, a rearward wall spaced from the forward wall to form a fluid flow path therebetween, and a flexible bellows provided at an upper end of the suction nozzle assembly wherein flexible bellows is configured to contract when the suction nozzle assembly moves upward relative to the base and expands as the nozzle assembly moves downward relative to the base;
- a recovery chamber;
- and
- a vacuum source in fluid communication with the suction nozzle assembly to draw fluid from the surface to be cleaned through the fluid flow path and deposit the fluid in the recovery chamber.
