— models with reduced body height, designed for cleaning under low furniture: legged sofas, platform beds, and cabinets with a 7–8 cm clearance. Thanks to their flat profile, they go where standard 9–10 cm units hit the edge, but they usually compromise on dustbin volume and battery capacity, and often do without a LiDAR tower, relying on cameras/sensors for navigation. Compared with regular robots, these models collect dust from dead zones better, but are more sensitive to high thresholds and dense carpets.
