Canister vacuum cleaners consist of a lightweight cleaning wand for vacuuming floors or surfaces and a canister that houses the motor and dust collection system. The cleaning wand provides access underneath furniture. These canister vacuum cleaners also accept different attachments, such as a rolling brush head for vacuuming carpets or an extended nozzle for cleaning drapes, stairs, and hard-to-reach areas. The canister has wheels or handles for repositioning it during vacuuming. It uses bags or has an onboard chamber for collecting dirt and allergens.
