Abstract
A surface cleaning apparatus has a cyclone having a primary air inlet and a secondary air inlet. A primary air flow path extends a the floor dirty air inlet of a surface cleaning head to the primary air inlet of the cyclone. An above floor cleaning assembly comprising an above floor cleaning wand and a flexible hose, the above floor cleaning assembly having an auxiliary dirty air inlet. A secondary air flow path extends from the auxiliary dirty air inlet to the secondary air inlet of the cyclone. When the surface cleaning apparatus is useable in a floor cleaning mode in which air enters the surface cleaning apparatus via the primary dirty air inlet of the surface cleaning head and an above floor cleaning mode in which air enters the surface cleaning apparatus via the auxiliary dirty air inlet.
Claims17
A surface cleaning apparatus comprising:
- (a) an air treatment chamber having a primary air inlet and a secondary air inlet;
- (b) a surface cleaning head having a floor dirty air inlet;
- (c) a primary air flow path from the floor dirty air inlet to the primary air inlet of the air treatment chamber, wherein the primary air inlet is provided at a first location of the air treatment chamber;
- (d) an above floor cleaning assembly comprising an above floor cleaning wand and a flexible hose, the above floor cleaning assembly having an auxiliary dirty air inlet;
- and,
- (e) a secondary air flow path from the auxiliary dirty air inlet to the secondary air inlet of the air treatment chamber, wherein the secondary air inlet is provided at a second location of the air treatment chamber,
- wherein the surface cleaning apparatus is useable in a floor cleaning mode in which air enters the surface cleaning apparatus via the floor dirty air inlet of the surface cleaning head and an above floor cleaning mode in which air enters the surface cleaning apparatus via the auxiliary dirty air inlet, and
- wherein a surface cleaning head valve is provided in the primary air flow path and an above floor cleaning assembly valve is provided in the secondary air flow path, the surface cleaning head valve and the above floor cleaning assembly valve operable together in a single action to alternately connect the floor dirty air inlet and the auxiliary dirty air inlet in air flow communication with the air treatment chamber.
A surface cleaning apparatus comprising:
- (f) an air treatment assembly comprising an air treatment chamber, the air treatment chamber having a primary air inlet and a secondary air inlet;
- (g) a surface cleaning head having a floor dirty air inlet;
- (h) a primary air flow path from the floor dirty air inlet to the primary air inlet of the air treatment chamber, wherein the primary air inlet is provided on an exterior wall of the air treatment chamber;
- (i) an above floor cleaning assembly comprising an above floor cleaning wand and a flexible hose, the above floor cleaning assembly having an auxiliary dirty air inlet;
- and,
- (j) a secondary air flow path from the auxiliary dirty air inlet to the secondary air inlet of the air treatment chamber, wherein the secondary air inlet is also provided on the exterior wall of the air treatment chamber,
- wherein the surface cleaning apparatus is useable in a floor cleaning mode in which air enters the surface cleaning apparatus via the floor dirty air inlet of the surface cleaning head and an above floor cleaning mode in which air enters the surface cleaning apparatus via the auxiliary dirty air inlet, and
- wherein the primary air flow path is openable automatically as the secondary air flow path is closed.
