Cleaning dark floors (7000, 3000 and 2000 Series) Your robot is equipped with anti-drop sensors to detect stairs and other floor-level differences so it can avoid them. Dark floors may be mistakenly identified as stairs so your robot will not drive onto them.
To help your robot recognise the dark floor, make sure that the room is well lit by turning on the lights.
