Much like a bat, the Trilobite sends out harmless ultrasonic signals to spot objects and avoid them. It begins by edging along the walls to map the size of the room, while simultaneously cleaning the edges. Then it efficiently cleans the whole room. Thanks to the suction technology inside, it not only picks up dust balls and stray cornflakes, but fine dust particles as well. A sophisticated suspension prevents the machine from getting stuck, and a special sensor stops it from ever falling down the stairs.
