Sure, a Roomba will methodically and accurately clean your floors, but wouldn't it be more fun to let chaos reign by throwing the controls of your robotic vacuum over to a hamster?

That is to say, whichever way the hamster runs, the Roomba goes. I'm sure it's quite liberating for the hamster, but I wouldn't count on your floors getting too clean. [Networkworld via Gadget Review]
