Claims17
An upright surface cleaning apparatus comprising:
- a) a surface cleaning head having a first dirty fluid inlet;
- b) at least one treatment unit comprising a first separation stage and a second separation stage that is downstream from the first separation stage, wherein the first separation stage comprises a liquid separator;
- c) an upright section moveably mounted to the surface cleaning head, the upright section moveable between an upright storage position and a reclined surface cleaning position, the upright section having the second separation stage and an above floor cleaning member comprising a second dirty fluid inlet and a flexible hose;
- d) a liquid deliver system extending from at least one fluid reservoir to at least one applicator nozzle;
- e) a floor cleaning fluid flow path extending from the first dirty fluid inlet to a clean air outlet, the floor cleaning fluid flow path including the first separation stage, the second separation stage and a suction motor;
- and,
- f) an above floor fluid flow path extending from the second dirty fluid inlet to the clean air outlet and including the second separation stage, the suction motor and the above floor cleaning member and excluding the first separation stage,
- wherein the upright surface cleaning apparatus is operable in a floor cleaning mode which utilizes the floor cleaning fluid flow path and an above floor cleaning mode which utilizes the above floor fluid flow path.
