Is there a robot vacuum with LiDAR under 3 inches?
Not among the 19 robots we checked. The lowest with a LiDAR tower are the Dreame X60 Ultra at 79.5 mm (3.13 in) and the Roborock Saros 10R at 79.8 mm (3.14 in), both only with the sensor lowered. The eufy C10 is under 3 inches and uses a point laser, but it has no spinning LiDAR. Models we have not checked may exist.
