Robot Lawnmowers Are Getting Better at Knowing Where They Are, The Verge Finds

The Verge tested five robot lawnmowers from Segway, Mammotion, Husqvarna, Roborock, and Dreame on a three-quarter-acre South Carolina property, published August 13, 2026. Four of five use satellite positioning plus sensors like lidar — laser-based distance scanning — to stay on track when trees or buildings block the sky. Dreame alone skips satellites and relies only on lidar.
