The dirt is gathered by either a dustbag or a rigid cartridge, which may be emptied and reused.
Vacuum cleaners are used in homes as well as in industry, and exist in a variety of sizes and models.
Manufacturers and specific models include: Upright vacuum cleaners are an "all-in-one" unit, with the motor, dust collector, and cleaning head are all attached.
Models include: Canister vacuum cleaners separate their motor and dust collection system.
Handheld vacuum cleaners typically do not have a bag, rather most have a cup or cylinder for dust collection.
