Abstract
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.
