A canister vacuum consists of a wheeled body that is attached to a vacuum wand and power head via a flexible plastic hose. The canister portion of the vacuum contains the main motor, filter, and any dust bags; depending on the model, the power head may also contain a smaller motor. Canister vacuums usually feel lighter to use, as a user only needs to move the wand and power head during cleaning. Additionally, the wheels on the canister body make it easy to drag the vacuum around a room.
