Cyclonic separating apparatus

A cyclonic separating apparatus comprising a first cyclonic separating unit and, downstream from the first cyclonic separating unit, a second cyclonic separating unit comprising a plurality of cyclones arranged fluidly in parallel about a first axis and a dust collector arranged to receive dust from each of the plurality of cyclones, each of the plurality of cyclones in the second cyclonic separation unit comprising a fluid inlet and a fluid outlet, the plurality of cyclones being divided into at least a first set of cyclones and a second set of cyclones, the fluid inlets of the first set of cyclones being arranged in a first group and the fluid inlets of the second set of cyclones being arranged in a second group that is spaced along the first axis from the first group such that the fluid inlets of the second group are non-overlapping with the fluid inlets of the first group in a direction that is parallel to the first axis, wherein each outlet of the plurality of cyclones in the second cyclonic separation unit is provided by a common vortex finder plate that comprises a first portion that includes vortex finders for the first set of cyclones and a second portion that includes vortex finders for the second set of cyclones, and wherein the second portion is spaced apart from the first portion in the direction that is parallel to the first axis.
