Maneuverability is at the top of the list for canister proponents, who like the ease of vacuuming under coffee tables and other low-profile furniture which is a difficult or impossible task with a traditional upright model. Canisters are generally compact and lightweight, making them ideal for carrying up and down stairs. Because the bulk of the cleaner's weight is in the canister itself, using a canister vacuum is not a difficult chore. A relatively lightweight head at the end of the hose and wand is extremely easy to push across bare floors as well as deep-pile carpet, and because only the head travels, canisters can go where no upright can go.
