Independent rankings
Robot vacuums ordered by height, lowest first, from the makers' own dimensions: every machine we list that is 90 mm tall or less, with the height printed on each row.
Ordered by the published height, lowest first, with the weighted score deciding between equal figures; machines taller than 90 mm or without published dimensions are not on the list. For a robot with a retracting LiDAR the figure is the height with the turret down, which is how it drives under furniture. Measure the lowest edge of the sofa or the bed frame, not the legs, and leave a few millimetres: a robot that fits exactly wedges on the first uneven board.
