Cyclonic cleaners do not use filtration bags. Instead, the dust is separated in a detachable cylindrical collection vessel or bin. Air and dust are sucked at high speed into the collection vessel at a direction tangential to the vessel wall, creating a fast-spinning vortex.
The dust particles and other debris move to the outside of the vessel by centrifugal force, where they fall due to gravity. Statewide carry a range of genuine and generic spare parts and consumables for Electrolux, Volta and Dyson cyclonic units to keep your vacuum maintaining its best suction.
