The Dreame Roboticmower A1, a new robot lawnmower, can tackle yards as large as half an acre, which is good news for us Americans with big yards.

These electric autonomous grass-cutting devices have struggled to take off in the US due to range issues, complexity, and high costs.

While Dreame’s bot may cost as much as $2,000 (pricing isn't finalized) it uses lidar mapping so there’s no need for clunky beacons or fiddly guide wire.
