A cyclonic separator assembly having a first end, a second end, and an inlet for receiving a flow of dirty air. A separation chamber receives dirty air from the inlet and includes an air flow outlet formed within the separation chamber configured such that air is drawn through the outlet in a direction generally towards the first end of the separator assembly. The chamber further includes a dirt outlet defining an opening in a wall of the separation chamber. The assembly further includes a passage defining an air flow path from the air flow outlet towards a separator outlet in a direction generally towards the second end of the separator assembly such that, in use, the separator outlet is adapted to communicate with the suction inlet of the cleaner body so as to draw dirty air into the separator assembly.

A dust cup assembly and a handheld cleaner having the same are provided. The dust cup assembly includes: a cup casing having an opening; a device housing disposed in the cup casing and defining a dust removal chamber together with the cup casing, wherein a part of the device housing has an air exhaust port and the air exhaust port is disposed at the opening and exposed from the opening; and a negative pressure device located within the device housing, and configured to allow dusty air to enter the dust removal chamber for dust and air separation, and airstream separated from the dust removal chamber to enter the device housing and to be exhausted through the air exhaust port.

A cyclonic separator device for removing dust or debris from dirt-laden air, the device having a separating chamber, an inlet, an outlet, and a shroud that is connected to the separating chamber at one end, and provides a plurality of openings for the passage of air to the outlet. The device further includes a dirt collection chamber in communication with the separating chamber. The separating chamber includes an airflow directing formation which is connected to an inner surface of a generally cylindrical portion and which extends inwardly towards a central axis of the generally cylindrical portion. The airflow directing formation provides a surface which follows a substantially helical path that extends away from the inlet as it extends circumferentially around the inner surface of the generally cylindrical portion.

A cyclone separator useable in a surface cleaning apparatus comprises a cyclone chamber and a dirt collection chamber exterior to, and surrounding at least a portion of the cyclone chamber. The dirt collection chamber is in communication with the cyclone chamber via a dirt outlet. An air flow passage extending to the cyclone air inlet travels generally axially through the dirt collection chamber.
