Abstract

An all in the head surface cleaning apparatus can include a surface cleaning head having a brush motor that can be drivingly connected to a moveable brushing member. The brush motor may have a brush motor axis. The surface cleaning head can include a cyclone comprising a cyclone chamber. The cyclone may have a longitudinal cyclone axis. The surface cleaning head can include a suction motor having a first end, a second end. A suction motor axis may extend between the first and second ends. At least a portion of the brush motor may be located between the first and second ends of the suction motor. An upper portion may be moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion comprising a drive handle.

Claims

1. An all in the head surface cleaning apparatus comprising:

(a) a surface cleaning head comprising;

(i) a front end, a rear end, first and second laterally opposed sidewalls and an air flow path extending from a dirty air inlet to a clean air outlet;

(ii) a brush motor drivingly connected to a moveable brushing member, the brush motor having a brush motor axis;

(iii) a cyclone comprising a cyclone chamber, the cyclone having a longitudinal cyclone axis;

(iv) a suction motor having a first end, a second end and a suction motor axis extending between the first and second ends,

wherein at least a portion of the brush motor is located between the first and second ends of the suction motor; and

,

(b) an upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion comprising a drive handle

wherein the cyclone chamber is positioned on one lateral side of the surface cleaning head and the brush motor is positioned on the other lateral side of the surface cleaning head.

2. The apparatus of claim 1 wherein the suction and brush motor axes are generally parallel.

3. The apparatus of claim 2 wherein the suction and brush motor axes are oriented generally transverse to a forward direction of travel.

4. The apparatus of claim 3 wherein the brush motor is positioned forward or rearward of the suction motor.

5. The apparatus of claim 4 wherein a majority of the brush motor is located between the first and second ends of the suction motor.

6. The apparatus of claim 3 wherein the brush motor is positioned forward of the suction motor.

7. The apparatus of claim 6 wherein the brush motor is positioned forward of the cyclone chamber.

8. The apparatus of claim 2 wherein the cyclone axis is generally parallel to the suction motor axis.

9. The apparatus of claim 8 wherein the suction and brush motor axes are oriented generally transverse to a forward direction of travel.

10. The apparatus of claim 1 wherein the cyclone chamber has an air outlet end that is opposed to and faces an air inlet end of the suction motor and the suction motor and cyclone axes are generally parallel.

11. The apparatus of claim 1 wherein the cyclone comprises a dirt collection chamber and the brush motor has an end that is opposed to and faces an end of the dirt collection chamber.

12. The apparatus of claim 11 wherein the dirt collection chamber is positioned forward or rearward of the cyclone chamber.

13. The apparatus of claim 12 wherein the dirt collection chamber is positioned on one lateral side of the surface cleaning head and the brush motor is positioned on the other lateral side of the surface cleaning head.

14. The apparatus of claim 1 wherein the cyclone comprises a dirt collection chamber having inner and outer laterally opposed ends, the brush motor has inner and outer laterally opposed ends, the cyclone and brush motor axes are oriented generally transverse to a forward direction of travel whereby the cyclone axis intersects a projection of the inner and outer laterally opposed ends of the dirt collection chamber, the brush motor axis intersects the inner and outer laterally opposed ends of the brush motor and the inner lateral end of the brush motor is opposed to and faces the inner lateral end of the dirt collection chamber.

15. The apparatus of claim 1 wherein the upper portion comprises a first end coupled to the surface cleaning head and a second end spaced apart from the first end and wherein the drive handle is disposed toward the second end.

16. The apparatus of claim 1 further comprising a mounting hub extending from the rear side of the surface cleaning head, the upper portion being moveably mounted to the mounting hub and being rotatably connected to the mounting hub whereby the upper portion is rotatable about a rotation axis relative to the surface cleaning head.

17. The apparatus of claim 1 wherein the surface cleaning head has a lower end having the dirt air inlet, the suction motor has an upper end and a lower end and the brush motor axis is located between the upper and lower ends of the suction motor.

18. The apparatus of claim 1 wherein the surface cleaning head has a lower end having the dirt air inlet, the cyclone has an upper end and a lower end and the brush motor axis is located between the upper and lower ends of the cyclone.

19. The apparatus of claim 18 wherein the suction motor has an upper end and a lower end and the brush motor axis is located between the upper and lower ends of the suction motor.

20. An all in the head surface cleaning apparatus comprising:

(a) a surface cleaning head comprising;

(i) a front end, a rear end, first and second laterally opposed sidewalls and an air flow path extending from a dirty air inlet to a clean air outlet;

(ii) a brush motor drivingly connected to a moveable brushing member, the brush motor having a brush motor axis;

(iii) a cyclone comprising a cyclone chamber, the cyclone having a longitudinal cyclone axis;

(iv) a suction motor having a first end, a second end and a suction motor axis extending between the first and second ends,

wherein at least a portion of the brush motor is located between the first and second ends of the suction motor; and

,

(b) an upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion comprising a drive handle

wherein the cyclone comprises a dirt collection chamber and the brush motor has an end that is opposed to and faces an end of the dirt collection chamber.
