8. The vacuum cleaner of claim 7 wherein the at least one vertically extending member has a generally right angle shape.

9. A vacuum cleaner having an air flow path from a dirty air inlet to a clean air outlet the vacuum cleaner comprising:

(a) a cyclone comprising a cyclone chamber having a cyclone axis of rotation, an axial height, a first end, an axially spaced apart second end, a cyclone sidewall extending between first and second axially spaced apart end walls, a cyclone air inlet, a cyclone air outlet and a dirt outlet; and,

(b) a dirt collection chamber exterior to the cyclone chamber and extending along at least a portion of an axial length of the cyclone chamber and in communication with the cyclone chamber via the dirt outlet, the dirt collection chamber comprising a first end, an axially spaced apart second end, a dirt collection chamber sidewall extending between first and second axially spaced apart end walls and at least one porous vertically extending member provided within the dirt collection chamber.

10. The vacuum cleaner of claim 9 wherein the at least one vertically extending member is positioned in the dirt collection chamber at a location that is axially spaced from the dirt outlet.

11. The vacuum cleaner of claim 9 wherein the at least one vertically extending member is provided at an end of the dirt collection chamber.

12. The vacuum cleaner of claim 9 wherein the dirt outlet is provided at a first end of the dirt collection chamber and the at least one vertically extending member is provided at the second end of the cyclone chamber.

13. The vacuum cleaner of claim 12 wherein the at least one vertically extending member is positioned radially inwardly from the dirt collection chamber sidewall.

14. The vacuum cleaner of claim 13 wherein the at least one vertically extending member is generally planar.

15. The vacuum cleaner of claim 9 wherein the at least one vertically extending member is generally planar.

16. The vacuum cleaner of claim 9 wherein the at least one vertically extending member is removably mounted in the dirt collection chamber.

17. The vacuum cleaner of claim 16 wherein the second end of the dirt collection chamber is openable and the at least one vertically extending member is removable from the dirt collection chamber when the second end is opened.

18. The vacuum cleaner of claim 17 wherein the second end wall is moveable between a closed position and an open position and the at least one vertically extending member is mounted to the second end wall.

19. The vacuum cleaner of claim 17 wherein the second end wall is moveable between a closed position and an open position, the second end wall has a first side that is moveably mounted to the dirt collection chamber sidewall and an opposed second side and a first portion of the at least one vertically extending member towards the first side has a first axial height and a second portion of the at least one vertically extending member towards the second side has a second axial height, which is less than the first axial height.

20. A vacuum cleaner having an air flow path from a dirty air inlet to a clean air outlet the vacuum cleaner comprising:

(a) a cyclone comprising a cyclone chamber having a cyclone axis of rotation, an axial height, a first end, an axially spaced apart second end, a cyclone sidewall extending between first and second axially spaced apart end walls, a cyclone air inlet, a cyclone air outlet and a dirt outlet; and,

(b) a dirt collection chamber exterior to the cyclone chamber and in communication with the cyclone chamber via the dirt outlet, the dirt collection chamber comprising a first end, an axially spaced apart openable second end, a dirt collection chamber sidewall extending between first and second axially spaced apart end walls and at least one vertically extending member,
