So you’ve heard of the Roomba, right? The device that sweeps your living room for you? Well, if you’ve ever wondered when someone would invent one for the lawn, your prayers have been answered, via the aptly-named Auto Mower from Husqvarna, which runs on its own and can be set to operate at a specific time. Auto Mower works in the rain, climbs inclines, and turns around when it bumps into something. It’s even quiet enough to run at night! Just bury a “boundary wire” around your lawn, so Auto Mower will know not to slay your prize-winning petunias. The device runs on a rechargeable battery, and comes with a dock. And don’t worry: no one can steal your new best friend, as a 4-digit pin number is required to even pick it up. Auto Mower is available (at only a few stores) for $2000. Sounds high, until you compare it to lawnmower fuel costs, hiring someone to mow it for you, or just having some extra free time.
