Abstract

An upright vacuum cleaner has a cleaning head for cleaning a surface and an upper body portion mounted on the cleaning head. The upper portion comprises a longitudinally extending axis, at least one cyclone having an air entry port and a motor positioned above the at least one cyclone and in air flow communication with the at least one cyclone.

Claims

1. An upright vacuum cleaner comprising:

(a) a cleaning head;

(b) an upper body portion pivotally mounted on the cleaning head, the upper body portion comprising a cyclonic cleaning stage; and

,

(c) only a single motor for producing air flow through the vacuum cleaner positioned above the cyclonic cleaning stage when the upper body portion is pivoted to be generally vertical.

2. The vacuum cleaner as claimed in claim 1 further comprising a second cyclonic cleaning stage downstream from the cyclonic cleaning stage.

3. The vacuum cleaner as claimed in claim 1 further comprising a further cleaning member positioned between the cyclonic cleaning stage and the motor.

4. The vacuum cleaner as claimed in claim 2 wherein the further cleaning member comprises an electrostatic cleaning member.

5. The vacuum cleaner as claimed in claim 4 further comprising a second electrostatic cleaning member downstream from the motor.

6. The vacuum cleaner as claimed in claim 3 wherein the cyclonic cleaning stage is the primary dirt separation member.

7. The vacuum cleaner as claimed in claim 1 wherein the cleaning head has a brush.

8. The vacuum cleaner as claimed in claim 1 wherein the cleaning head has a rotating brush.
