Abstract
A surface cleaning apparatus comprising a surface cleaning head, the surface cleaning head comprising a first liquid separation stage comprising a cyclone having a cyclone axis of rotation, a cyclone first end, an axially spaced apart second end, a cyclone air inlet, a cyclone air outlet and an axially extending sidewall wherein a portion of the sidewall comprises a screen and, when the surface cleaning apparatus is in use to clean a floor, the cyclone axis of rotation extends generally horizontally and, a first liquid collection region that is positioned at a lower elevation than the screen.
Claims20
A surface cleaning apparatus comprising:
- (a) a first liquid separation stage comprising a cyclone having a cyclone axis of rotation, a cyclone first end, an axially spaced apart second end, a cyclone air inlet, a cyclone air outlet and an axially extending sidewall wherein a portion of the sidewall comprises a screen and, when the surface cleaning apparatus is in use to clean a floor, the cyclone axis of rotation extends generally horizontally;
- and,
- (b) a first liquid collection region that is positioned at a lower elevation than the screen.
A surface cleaning apparatus comprising:
- (a) a first liquid separation stage comprising a cyclone having a cyclone axis of rotation, a cyclone first end, an axially spaced apart second end, a cyclone air inlet, a cyclone air outlet, a separated liquid outlet and an axially extending sidewall, wherein when the surface cleaning apparatus is in use to clean a floor, the cyclone axis of rotation extends generally horizontally;
- and,
- (b) a first liquid collection region that is positioned at a lower elevation than the separated liquid outlet
- wherein the first liquid separation stage has an openable separated liquid outlet port that is in communication with the liquid collection region.
A surface cleaning apparatus comprising:
- (a) a first liquid separation stage comprising a cyclone having a cyclone axis of rotation, a cyclone first end, an axially spaced apart second end, a cyclone air inlet, a cyclone air outlet, a separated liquid outlet and an axially extending sidewall, wherein when the surface cleaning apparatus is in use to clean a floor, the cyclone axis of rotation extends generally horizontally;
- and,
- (b) a first liquid collection region that is positioned at a lower elevation than the separated liquid outlet,
- wherein the first liquid separation stage has an openable wall, the cyclone axis of rotation extends through the openable wall when the openable wall is in a closed position and the cyclone and the liquid collection region are opened when the openable wall is in an open position.
