Let's face it, vacuuming sucks. That's why a group of M.I.T. brainiacs created Roomba, a robot that vacuums your house for you. Running on rechargeable batteries, Roomba roams your house entirely on its own, swooping up dust bunnies and stray Cheerios and zipping under beds and couches where mere humans can't reach. Its sensors keep it from bumping into walls and furniture or falling off staircases. When it finishes a room, Roomba beeps proudly and turns itself off.
