A separator for removing dirt particles from an airflow, the separator comprising a first separation stage having an impeller, and a second separation stage having one or more cyclone bodies arranged in parallel, the first separation stage being upstream of the second separation stage. The impeller generates the airflow through the separator and concentrates the dirt particles within the airflow to produce a clean portion and a dirty portion of airflow, and wherein only the dirty portion of airflow is passed through the second separation stage.
