<p>A surface treating appliance such as a vacuum cleaner comprises a first cyclonic separating unit (20, fig 3) and, downstream from the first cyclonic separating unit (20, fig 3), a second cyclonic separating unit (22, fig 3) comprising a plurality of cyclones 50 arranged fluidly in parallel about a first axis (Y, fig 3) and a dust collector (24, fig 3) arranged to receive dust from each of the plurality of cyclones 50. Each of the plurality of cyclones 50 in the second cyclonic separation unit (24, fig 3) comprise a fluid inlet and a fluid outlet, the plurality of cyclones 50 being divided into at least a first set of cyclones 70 and a second set of cyclones 72, the fluid inlets of the first set of cyclones 70 being arranged in a first group and the fluid inlets of the second set of cyclones 72 being arranged in a second group spaced along said axis (Y, fig 3) from the first group 70. Each outlet of the plurality of cyclones in the second cyclonic separation unit is provided by a common plate-like vortex finder member 62. The vortex finder 62 member is also claimed.</p> |
