Configuration of a surface cleaning apparatus
A surface cleaning apparatus has a surface cleaning head having a pivoting connector, an upper end of the pivoting connector providing an air outlet of the surface cleaning head. A support consisting of an upflow duct is pivotally mounted to the surface cleaning head by the pivoting connector. A surface cleaning unit is vertically removably mounted to an upper end of the support. The surface cleaning unit comprises a cyclone unit, a pre-motor filter, a suction motor and flexible hose.
1. A surface cleaning apparatus comprising:
an air flow passage extending from a dirty air inlet to a clean air outlet;
a surface cleaning head having the dirty air inlet, the surface cleaning head having a pivoting connector;
a support pivotally mounted to the surface cleaning head by the pivoting connector;
a surface cleaning unit vertically removably mounted to an upper end of the support, the surface cleaning unit comprising:
(i) a cyclone unit positioned in the air flow passage, the cyclone unit comprising a cyclone chamber having a cyclone air inlet, a cyclone air outlet, a dirt outlet and a dirt collection chamber external to the cyclone chamber;
(ii) a pre-motor filter positioned in the air flow passage downstream from the cyclone air outlet;
(iii) a suction motor positioned in the air flow passage downstream from the pre-motor filter; and,
(iv) a flexible hose
wherein, when the surface cleaning unit is mounted to the support and the support extends vertically, the cyclone unit is mounted to an upper end of a suction motor housing and the surface cleaning unit is in a storage orientation and
wherein the cyclone unit is removably mounted to an upper end of the suction motor housing, and
wherein, when the surface cleaning unit is in the storage orientation, the cyclone unit has an openable upper end and, when the upper end of the cyclone unit is opened, the cyclone chamber and the dirt collection chamber are concurrently opened, and
wherein, when the surface cleaning unit is in the storage orientation mounted, the cyclone air inlet and the cyclone air outlet are provided at a lower end of the cyclone chamber and a dirt outlet is provided at an upper end of the cyclone chamber.
2. The surface cleaning apparatus of claim 1 wherein, in one portable mode, the surface cleaning unit remains in air flow communication with surface cleaning head as the surface cleaning unit is removed from the support.
3. The surface cleaning apparatus of claim 1 wherein, when the surface cleaning unit is mounted to the support and the support extends vertically, the surface cleaning unit overlies the surface cleaning head.
4. The surface cleaning apparatus of claim 3 wherein the dirty air inlet is provided at a front end of the surface cleaning head and, when the surface cleaning unit is mounted to the support and the support extends vertically, a rear side of the portable cleaning unit is mounted to the support and the portable cleaning unit is positioned forward of the support.
5. The surface cleaning apparatus of claim 1 wherein the dirt collection chamber comprises a portion that is positioned radially outwardly of the cyclone chamber.
