<p>Cyclonic separating apparatus 1 for a cleaning appliance such as a vacuum cleaner has a longitudinal axis 16, an upstream cyclonic separator 2 and a downstream cyclone assembly 8. The downstream cyclone assembly 8 comprises a plurality of cyclones 9a, 9b arranged in parallel with one another. The downstream cyclones 9a, 9b are arranged in a first set (14, fig 1) in which each cyclone has a longitudinal axis 10a inclined at a first angleαto the longitudinal axis 16 of the cyclonic separating apparatus 1 and a second set (15, fit 1), in which each cyclone has a longitudinal axis 10b inclined at a second angleβto the longitudinal axis 16 of the cyclonic separating apparatus 1. The second angleβis greater than the first angleα. The invention allows the downstream cyclone assembly 8 to be compactly packaged.</p> |
