What are some good self-propelled vacuums?

Self-propelled vacuum cleaners that receive high ratings from consumers include the Dyson DC65 Animal Upright Vacuum, the Shark Rocket HV301 Stick Vacuum and the Hoover WindTunnel UH70400 Upright Vacuum. These models and many other self-propelled vacuums may be available for purchase at retailers such as Sears, Walmart and Amazon.com.

The iRobot Roomba also receives good ratings from consumers on many websites. After its battery charges, it can run completely on its own, without requiring a person to push it, for about two hours. It has padded bumpers to prevent damage to furniture and walls, in case it bumps into them.
