A vacuum cleaner having a vac motor and a separating assembly for separating out dust particles entrained in an airflow drawn through the separator by the vac motor. The separating assembly is a multi-stage separating assembly comprising a primary separation stage and a secondary, non-cyclonic separation stage which is downstream of the primary separation stage, the non-cyclonic separation stage comprising a flow bend for changing the direction of the airflow thereby to separate out dust particles entrained in the airflow. A primary dust collector is provided for collecting dust particles separated out by the first separation stage, and a secondary dust collector is provided for collecting the dust particles separated out by the flow bend, wherein the primary dust collector at least partly surrounds the secondary dust collector.

Separating apparatus in a vacuum cleaner

A vacuum cleaner having a vac-motor and a dust separator for separating out dust particles entrained in an airflow drawn through the separator by the vac-motor. The separator is a multi-stage separator incorporating a cyclonic primary separation stage, a non-cyclonic secondary separation stage which is downstream of the primary separation stage and a cyclonic tertiary stage which is downstream of the secondary stage. In accordance with the invention, the secondary stage includes a flow bend for changing the direction of the airflow thereby to separate out dust particles entrained in the airflow. The vacuum cleaner also includes a primary dust collector for collecting dust particles separated out by the primary separation stage, a secondary dust collector for collecting the dust particles separated out by the flow bend and a tertiary dust collector for collecting dust separated out by the tertiary separation stage.
