Abstract

A surface cleaning apparatus comprises a floor cleaning unit and an upright section comprising a handle drivingly connected to the surface cleaning head. The surface cleaning apparatus also comprises a cyclone mounted on the upright section and positioned in the air flow passage. The cyclone is inverted and/or has an external dirt collection chamber.

Claims

1. An upright surface cleaning apparatus comprising:

(a) a floor cleaning unit comprising a surface cleaning head having a dirty air inlet, a cleaning head air outlet and an upright section comprising a handle drivingly connected to the surface cleaning head;

(b) a cyclone unit positioned in the air flow passage, the cyclone unit comprising a cyclone having an air inlet located at a lower end of the cyclone and an air outlet and a dirt outlet provided at an upper end of the cyclone, and a dirt collection chamber exterior to the cyclone and surrounding at least a portion of the cyclone;

(c) a suction motor positioned in the air flow path; and

,

(d) a surface cleaning unit removably mounted to the handle wherein the surface cleaning unit comprises the cyclone unit and the suction motor.

2. The surface cleaning apparatus of claim 1 wherein the cyclone and the dirt collection chamber are concurrently openable.

3. The surface cleaning apparatus of claim 1 wherein the cyclone is positioned interior of the dirt collection chamber.

4. The surface cleaning apparatus of claim 1 further comprising a plate facing the dirt outlet.

5. The surface cleaning apparatus of claim 4 wherein the plate is mounted to an upper end of the cyclone unit.

6. The surface cleaning apparatus of claim 5 wherein the cyclone is an inverted cyclone having an air inlet and an air outlet at a lower end of the cyclone.

7. The surface cleaning apparatus of claim 1 further comprising a vortex finder that is provided on an openable door of the cyclone.

8. The surface cleaning apparatus of claim 1 wherein the handle comprises a portion of the air flow path.

9. An upright surface cleaning apparatus comprising:

(a) a floor cleaning unit comprising a surface cleaning head having a dirty air inlet, a cleaning head air outlet and an upright section comprising a handle drivingly connected to the surface cleaning head;

(b) a cyclone unit mounted on the upright section and positioned in the air flow passage, the cyclone unit comprising a cyclone having an air inlet located at a lower end of the cyclone and an air outlet and a dirt outlet provided at an upper end of the cyclone, and a dirt collection chamber exterior to the cyclone and surrounding at least a portion of the cyclone wherein the cyclone unit is removable in a closed configuration; and

,

(c) a suction motor positioned in the air flow path.

10. The surface cleaning apparatus of claim 9 further comprising a surface cleaning unit removably mounted to the handle wherein the surface cleaning unit comprises the cyclone unit and the suction motor.

11. The surface cleaning apparatus of claim 9 wherein the cyclone and the dirt collection chamber are concurrently openable.

12. The surface cleaning apparatus of claim 9 wherein the cyclone is positioned interior of the dirt collection chamber.

13. The surface cleaning apparatus of claim 9 further comprising a plate facing the dirt outlet.

14. The surface cleaning apparatus of claim 13 wherein the plate is mounted to an upper end of the cyclone unit.

15. The surface cleaning apparatus of claim 14 wherein the cyclone is an inverted cyclone having an air inlet and an air outlet at a lower end of the cyclone.

16. The surface cleaning apparatus of claim 9 further comprising a vortex finder that is provided on an openable door of the cyclone.
