Abstract
An upright surface cleaning apparatus such as an extractor has an upright section moveably mounted to a surface cleaning head. The upright section comprises a first stage liquid separator and a second stage cyclone separator, wherein the cyclone separator is positioned above and downstream from the first stage liquid separator when the upright section is in the storage position.
Claims20
A surface cleaning apparatus comprising:
- a) a surface cleaning head having a front end having a dirty fluid inlet;
- and,
- b) 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 comprising a front side, a rear side, a first stage non-cyclonic liquid separator having a liquid separator fluid inlet downstream from the dirty fluid inlet and a liquid separator fluid outlet, a second stage cyclone separator comprising a cyclone chamber having a cyclone chamber fluid inlet and a cyclone chamber fluid outlet and a suction motor downstream from the second stage cyclone separator, the suction motor having a suction motor inlet end, wherein the cyclone separator is positioned above and downstream from the first stage liquid separator when the upright section is in the storage position, wherein a vertical line intersects the cyclone chamber and the liquid separator fluid inlet.
A surface cleaning apparatus comprising:
