Does a Robotic Lawn Mower Really Cut It?

Give the job to a robot. Robotic mowers resemble a Roomba, except they target grass instead of dust bunnies--traveling around your yard to keep your pasture in check with their spinning blades. Unlike their gas-guzzling, human-steered counterparts, these battery-powered bots are quiet enough to work at night (making about as much noise as a window-unit air conditioner). And because they run automatically on a schedule you set, you can deploy them with abandon. In fact, a robotic mower performs most effectively when used a few times a week, trimming a small amount each time.
