2 Tier Radial™ cyclones
15 cyclones each generate powerful g-forces to fling dust into the bin. The post-motor filter is 1.5m of ePTFE porous membrane sandwiched between layers of PE/PET, folded 158 times to fit in a compact space. It’s optimised to provide filtration with minimal pressure consumption, for more suction. So it captures microscopic dirt particles as small as 0.3 microns – almost 100 times smaller than the width of a human hair.
