A cyclonic separation apparatus for a vacuum cleaner, the cyclonic separation apparatus comprising: a cyclone (484) with a hollow cylindrical body (485), a hollow frusro--conical body (486) tapering away from the cylindrical body and a longitudinal central axis (457) through the cylindrical body and the frustro-conical body; a discharge nozzle (487) through the frustro-conical body at a longitudinal end; an air inlet port (488) arranged tangentially through a side of the cylindrical body; and an air outlet port (456) through the cylindrical body at an opposite longitudinal end; a dirt container in communication with the cyclone; and a deflector fin (454) arranged within the cyclone to deflect, in use, air flow from the air inlet port in a helical path around the cyclone and towards the discharge nozzle. A vacuum cleaner comprising a motor coupled to a fan and the cyclonic separation apparatus.
