A vortex finder plate for use in a cyclonic separating apparatus, such as that used in a vacuum cleaner, comprises a support structure 46 and a plurality of vortex finder support flaps 48 extending from the support structure 46, each vortex finder support flap 48 includes a vortex finder 8, wherein in that at least one vortex finder support flap 48 is connected to the support structure 46 by a hinge 50. In use the vortex finder 8 sits in the top of a cyclone of a multi-cyclone arrangement and acts as a discharge pipe. The hinge 8 is preferably an area of reduced thickness such as a score line and each flap 48 may pivot independently. An air duct (54, fig 5a) may extend through the centre of the support structure 46.
