Edge and wall sensors
Dust on Bob’s wall and edge sensors can reduce his performance. Bob's wall
sensors are located along his bumper, and his edge sensors are located on his
underside. Regularly cleaning these sensors ensures that Bob keeps working at
his best.
To do so:
Wipe the wall and edge sensors using a soft cloth slightly dampened with cold
water or alcohol.
