A twin cyclone arrangement has a secondary cyclone 140, or cyclone array (40,fig3), such as to separate finer dust, housed generally concentrically within the main body 20, 80 of a primary cyclone 20,80. Dust from both primary and secondary cyclones falls into a common dust collection container 80, which can be removed in a single go from engagement with both cyclones. The housing of the second cyclone within the first may also make for a more compact overall unit. The arrangement may also feature a flexible skirt 90 which may retain any particularly large sucked up items in an outer portion 86 of the dust collection chamber 80. |
