ABSTRACT:
A cyclonic separating apparatus includes a cyclonic separator for separating dirt and dust from an airflow, an inlet to the cyclonic separator and a shroud comprising a wall having a multiplicity of through-holes forming an outlet from the cyclonic separator. The apparatus also includes a plurality of separate passageways provided immediately downstream of the through-holes. By providing this arrangement, the separate passageways can be located around other parts of the cyclonic separating apparatus inwardly of the shroud, allowing for better packaging of the components of the cyclonic separating apparatus. The shroud may be reduced in size because some of the space previously required for a single, large passageway can be used for other components of the cyclonic separating apparatus such a collector or a cyclone. The reduction in size of the shroud in turn allows for the cyclonic separating apparatus to be more compact.
