If you're thinking of buying an upright or cylinder/canister vacuum cleaner, consider these points:

• TYPE: canister (lie parallel to the floor) are better for cleaning stairs and cars, or upright (may have powered cleaning head)
• SIZE: disposable bags or bagless (Dyson style). Bag models hold more and have replaceable filters
• POWER: some models use the motor power (eg. 1800w motor), some say suction power (eg. 320w suction)
• FEATURES: dist/hair filters, HEPA filter,power head, weight, warranty
• CLEANING: consider ease of cleaning blockages, removable filters
