Dirt and Dust Cyclonic Separating Apparatus

Abstract

A cyclonic separating apparatus includes a first cyclonic separating unit including at least one first cyclone, a second cyclonic separating unit located downstream of the first cyclonic separating unit and including at least one second clone, and a third cyclonic separating unit located downstream of the second cyclonic separating unit and including at least one third cyclone. The separation efficiency of the second cyclonic separating unit is substantially the same as the separation efficiency of either the first cyclonic separating unit or the third separating unit, providing an apparatus which achieves a higher separation efficiency than known separation apparatus.
