Robot mowers are fairly new lawn care technology. They operate in much the same way as a robot vacuum or mop does: moving in randomized patterns, avoiding obstacles with sensors, staying within boundaries set up by guidewires, and allowing scheduling and monitoring via Bluetooth companion apps. But instead of cleaning up spilled popcorn and pet hair, they cut your grass. Robot mowers are perfect for smaller suburban lawns because they have very small cutting decks, often just 8 or 9 inches wide. The included reels of guidewire also are often just big enough to mark off the edge of a quarter acre to half acre lot or the same size area of much larger lawns. The appeal of a robot lawn mower is that they are fully autonomous. Once you set up a schedule, you don’t have to worry about being home to mow your lawn; the unit will leave the base station and start cutting the grass all on its own once it is time to start.
Another big selling point is that since they’re battery-powered, they have zero emissions, which makes them a much more environmentally friendly solution to caring for your lawn. And not having a gas engine means very little maintenance other than charging batteries and cleaning out dried grass and dirt. To help you find the right fit for your lawn, I gathered up five of the best robot mowers available to buy. I broke down their features and analyzed their maximum cutting areas to curate a list of robot mowers that will suit a variety of different needs.
