Abstract

A handheld vacuum cleaner including a handle by which the vacuum cleaner is supported during normal use and a cyclonic separating unit having a longitudinal axis and a dirt collector at one end of the cyclonic separating unit. The cyclonic separating unit includes an end portion having a closed configuration in which dirt is retained within the dirt collector and an open configuration for the removal of dirt from the dirt collector. The handle has a pistol grip configuration in which the handle is inclined with respect to the cyclonic separating unit to form an angle of not less than 85 degrees and not greater than 140 degrees between the handle and the longitudinal axis of the cyclonic separating unit.

Claims

1. A handheld vacuum cleaner comprising:

a handle by which the vacuum cleaner is supported during normal use;

a cyclonic separating unit having a longitudinal axis and a dirt collector at one end of the cyclonic separating unit, the cyclonic separating unit comprising an end portion having a closed configuration in which dirt is retained within the dirt collector by the end portion and an open configuration for the removal of dirt from the dirt collector, wherein the handle has a pistol grip configuration in which the handle is inclined with respect to the cyclonic separating unit to form an angle of not less than 85 degrees and not greater than 140 degrees between the handle and the longitudinal axis of the cyclonic separating unit.

2. The handheld vacuum cleaner of claim 1, wherein the handle is inclined with respect to the cyclonic separating unit to form an angle of not less than 100 degrees and not greater than 125 degrees between the handle and the longitudinal axis of the cyclonic separating unit.

3. The handheld vacuum cleaner of claim 1, wherein the end portion comprises an end wall of the cyclonic separating unit.

4. The handheld vacuum cleaner of claim 1, wherein the end portion is arranged to pivot between the closed configuration and the open configuration.

5. The handheld vacuum cleaner of claim 1, wherein the cyclonic separating unit comprises a dirty air inlet through the end portion.

6. The handheld vacuum cleaner of claim 1, further comprising a connector and a cleaning tool connectable to the connector, wherein the cleaning tool is configured such that when the end portion is in the closed configuration and the cleaning tool is connected to the connector movement of the end portion from the closed configuration into the open configuration is prevented.

7. The handheld vacuum cleaner of claim 6, wherein the cleaning tool comprises a collar which abuts the end portion in order to hold the end portion in the closed configuration.

8. The handheld vacuum cleaner of claim 1, wherein the dirt collector is disposed forward of the handle.

9. The handheld vacuum cleaner of claim 1, wherein the longitudinal axis of the cyclonic separating unit extends in a plane which is located above the handle.

10. The handheld vacuum cleaner of claim 1, wherein the cyclonic separating unit comprises a cyclonic separation having an axis that defines the longitudinal axis of the cyclonic separating unit.
