3. The surface cleaning apparatus of claim 1 wherein the openable end of the dirt collection chamber is a bottom.
4. The surface cleaning apparatus as claimed in claim 1 wherein the plate is automatically moved to the emptying position when the openable end is opened.
5. The surface cleaning apparatus as claimed in claim 1 wherein the plate is supported by the openable end.
6. The surface cleaning apparatus as claimed in claim 1 wherein the openable end is removable from the cyclone separator.
7. The surface cleaning apparatus as claimed in claim 1 wherein the openable end is pivotally mounted to the cyclone separator.
8. The surface cleaning apparatus as claimed in claim 1 further comprising a cyclonic stage downstream from the cyclone separator and comprising a plurality of cyclones in parallel wherein at least some of the plurality of cyclones is each provided with a divider plate.
9. A surface cleaning apparatus comprising:
(a) a dirt inlet;
(b) a handle;
(c) a cyclone separator comprising a cyclone chamber and a dirt collection chamber, the cyclone separator having a fluid inlet downstream from the dirt air inlet, an openable end and a fluid outlet;
(d) a plate positioned between the cyclone chamber and the dirt collection chamber at an openable end, the plate is moveably mounted between an in use position and an emptying position wherein the plate is in a position to permit dirt in the cyclone chamber and the dirt collection chamber to be removed concurrently; and
(e) a fluid flow motor.
10. The surface cleaning apparatus of claim 9 wherein the plate has a hand grip portion.
11. The surface cleaning apparatus of claim 10 wherein the hand grip portion comprises a shaft extending away from the plate.
12. The surface cleaning apparatus of claim 9 wherein the dirt collection chamber extends under the plate.
13. The surface cleaning apparatus of claim 9 wherein a flow director having a flow directing surface that extends inwardly and downwardly into the cyclone chamber from the outer wall of the cyclone chamber to a position above the plate.
14. The surface cleaning apparatus as claimed in claim 9 wherein the surface cleaning apparatus is selected from the group consisting of a vacuum cleaner, a sweeper and a carpet extractor.
15. The surface cleaning apparatus of claim 9 wherein the plate is moveable subsequent to the openable end being opened.
16. A surface cleaning apparatus comprising:
(a) a dirt inlet;
(b) a handle;
(c) a cyclone separator comprising a cyclone chamber and a dirt collection chamber, the cyclone separator having a fluid inlet downstream from the dirt air inlet, an openable end and a fluid outlet;
(d) a plate positioned between the cyclone chamber and the dirt collection chamber, wherein the plate is pivotally mounted to the outer wall of the cyclone separator; and,
(e) a fluid flow motor.
17. The surface cleaning apparatus as claimed in claim 16 wherein the plate is pivotally mounted to the cyclone chamber.
18. A surface cleaning apparatus comprising:
(a) a dirt inlet;
(b) a handle;
(c) a cyclonic unit comprising a cyclone chamber and a dirt collection chamber and having an openable end;
(d) the cyclone chamber having an outer wall, a fluid inlet downstream from the dirt air inlet and a fluid outlet;
(e) a plate positioned at the openable end and having a cyclone chamber surface and positioned between the cyclone chamber and the dirt collection chamber, the plate being supported by the openable end; the plate is moveably mounted between an in use position and an emptying position wherein, in the emptying position, the plate is in a position to permit dirt in the cyclone chamber and the dirt collection chamber to be removed concurrently and,
(f) a fluid flow motor.
19. The surface cleaning apparatus as claimed in claim 18 wherein the plate is moveable to a emptying position when the openable end is opened.
