Abstract

A handheld cleaning appliance includes a dirty air inlet, a clean air outlet and separating apparatus for separating dirt and dust from an airflow in an airflow path leading from the air inlet to the air outlet. The cyclonic separator is arranged in a generally upright orientation. A base surface of the main body and a base surface of the cyclonic separator together form a base surface of the appliance for supporting the appliance on a surface. By providing a base surface of the appliance which is made up of the base surface of the main body and the base surface of the cyclonic separator, the appliance is provided with a substantial base surface on which the appliance can be stably and reliably supported. This is also achieved without substantially increasing the size of the appliance as a whole.

Claims

1. A handheld cleaning appliance comprising a main body, a dirty air inlet, a clean air outlet and a cyclonic separator for separating dirt and dust from an airflow located in an airflow path leading from the air inlet to the air outlet, the cyclonic separator being arranged in a generally upright orientation, wherein a base surface of the main body and a base surface of the cyclonic separator together form a base surface of the appliance for supporting the appliance on a surface.

2. The handheld cleaning appliance of claim 1, wherein the base surface of the main body is substantially planar and the base surface of the cyclonic separator is also substantially planar.

3. The handheld cleaning appliance of claim 2, wherein the base surface of the main body lies in the plane of the base surface of the cyclonic separator.

4. The handheld cleaning appliance of claim 1, 2 or 3, wherein the base surface of the main body lies adjacent the base surface of the cyclonic separator.

5. The handheld cleaning appliance of claim 1, 2 or 3, wherein the main body includes a motor or a battery.

6. The handheld cleaning appliance of claim 5, wherein the motor battery is arranged above the base surface of the main body.

7. The handheld cleaning appliance of claim 6, wherein the battery is arranged immediately above the base surface of the main body.

8. The handheld cleaning appliance of claim 1, 2 or 3, wherein the base surface of the main body is substantially rectangular in shape.

9. The handheld cleaning appliance of claim 1, 2 or 3, wherein the width of the base surface of the main body is at least one half of the width of the cyclonic separator.
