Canisters Vacuums

Canister (or cylinder or tank) designs have the motor and bag in a separate canister unit (usually mounted on wheels) connected to the vacuum head by a flexible hose. Although upright units have been tested as more effective (mainly because of the beaters), the lighter, more maneuverable heads of canister models are popular. Some upmarket canister models have power heads, which contain the same sort of mechanical beaters as in upright units, although such beaters are driven by a separate electric motor or air driven turbine. The turbine uses the suction power to spin the brushroll via a drive belt, but it requires the highest suction power to work effectively.
