Bob uses infrared light to detect stairs or edges in your home. Because dark carpeting tends to absorb infrared light, it can sometimes seem like an edge to Bob.
If Bob continually displays error 03 on his screen while he is working on dark carpeting, you may need to blindfold him.
Flip Bob over and you will see 4 clear sensors near his bumper.
Use the blindfold stickers that came in Bob’s box to blindfold him. Peel off the backs of each blindfold sticker and place one onto each of Bob's 4 sensors.
Make sure each sensor is fully covered. Remember, while Bob is blindfolded, he will not be able to detect stairs or edges!
