The Dual Cyclone™ system was a significant breakthrough in vacuum technology since the invention of the vacuum cleaner in 1901.
The traditional bag was replaced by two cyclone chambers which use centrifugal force to separate dust and dirt from the air. Larger particles are separated in the outer cyclone, while smaller particles are separated in the inner cyclone.
