Classic floor vacuum cleaners use an air pump to create a partial vacuum to suck up dust, dirt and air. Bag vacuum cleaners filter the dust and dirt particles out of the air. Various attachments provide optimal cleaning for different surfaces such as hard floors, carpeting and upholstery.
Bagless vacuum cleaners (e.g. Dyson, Electrolux or Samsung) create centrifugal force in the air flow, which separates dust and particles from the air. Cyclones remove particles up to a size of 0.5 microns. In contrast to bag vacuum cleaners, their bagless counterparts have no suction loss. Furthermore, there are no additional costs as no bags are needed.
