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 application_number US 25981408 A description a cylinder vacuum cleaner 10 incorporating cyclonic separating apparatus according to the invention is shown in fig1 and 2 the vacuum cleaner 10 has a main body 12 housing a motor and fan unit not shown and to which a pair of wheels 14 is attached the wheels 14 allow the main body 12 of the vacuum cleaner 10 to be maneuvered across a floor surface a dirty air inlet 16 is formed on the main body 12 a hose and wand assembly not shown can be connected to the dirty air inlet 16 in order to enable a user to clean a floor surface cyclonic separating apparatus 100 according to the invention is releasably attached to the main body 12 the interior of the cyclonic separating apparatus 100 is in communication with the dirty air inlet 16 through which a dirt laden airflow enters the cyclonic.
