iRobot Roomba 694 Robot Vacuum ($159, originally $275)

You're looking at the No. 1 bestseller among all of Amazon's robot vacuums, praised for how well it sucks up pet hair, dust, and dirt. It works on both carpet and hardwood floors, and its "Dirt Detect Technology" locates dirtier areas of your home and gives them a more thorough clean. You don't have to worry about it slamming into furniture or tumbling down the stairs because it has advanced sensors that prevent that. Plus, it works for 90 minutes before docking and recharging on its own.
