Abstract

The invention provides a vacuum cleaner (10) having a dirty air inlet (24), a clean air outlet, an airflow path therebetween, and dirt and dust separating apparatus (52) arranged in the airflow path between the dirty air inlet (24) and the clean air outlet, the dirt and dust separating apparatus (52) comprising a centrifugal separator (54) having a cylindrical or tapering chamber (62) with a tangential inlet (32) at a first end and a dirt and dust collection portion at the second end opposite the first end, an inner wall (74) being located inside the second end of the cylindrical chamber (62), wherein the centrifugal separator (54) is located so that the longitudinal axis (18) of the cylindrical chamber (62) is horizontal and a single fin or baffle (78) is provided on the inner wall (74) so as to extend inwards the wall of the cylindrical chamber (62) in a direction which is substantially parallel to that of the tangential inlet (32).
