Patent Images
1. A vacuum cleaner comprising:
- (a) a dirty air inlet in fluid communication with a source of suction, the source of suction producing an air stream through the vacuum cleaner;
(b) a dirt filter positioned downstream from the dirty air inlet, the dirt filter comprising at least first and second cyclone separation stages;
(c) the first cyclone separation stage comprising an upright cyclone having a first end, a second end positioned below the first end, a dirty air inlet positioned adjacent the first end, a cyclonic flow region and a cyclonic flow region exit; and
, (d) the second cyclonic separation stage positioned downstream from the first cyclone separation stage and comprising a plurality of inverted cyclones, each inverted cyclone having a first wider end, a second narrower end positioned above the first wider end, a dirty air inlet positioned adjacent the first wider end, a cyclonic flow region and a cyclonic flow region exit.

Abstract
A cyclone separator having an improved efficiency to remove a broader spectrum of contained particles is disclosed. The cyclone separator is provided with a member positioned to interact with at least the inner portion of a fluid circulating within the cyclone cavity to impart changes in the acceleration of the fluid as it rotates within the cyclone cavity.
