Bob’s Challenges
Bob is designed to maneuver around furniture of most shapes and sizes, but certain
congurations may confuse him temporarily. Bob may sometimes nd it dicult
to clean under chairs with narrow legs, or furniture that is too low for his bumper
sensors to detect. Irregularly-shaped furniture, such as chairs with circular bottoms,
may also confuse him for a moment — but don’t worry, Bob usually nds his way
around with time.
Blindfold stickers
Bob uses infrared light to detect edges and stairs; because dark-colored carpet
absorbs most light, it may seem like an edge to Bob’s sensors. If Bob continually
displays TROUBLE NR 04 on his screen while working on dark-colored carpet,
simply cover the four ground detection sensors on his underbelly with the blindfold
stickers that came in his box. Just remember that when Bob is “blindfolded” he will
not be able to detect edges or stairs!
Main brush
Bob’s main brush, which is designed to reach deep into carpet, may also have trou-
ble turning on rugs with long bers or fringes. You may remove Bob’s main brush
and allow him to vacuum without it when this happens.
Mop
Bob’s mop, which is attached to his bottom, is designed to sit at against the oor
and leave behind a clean trail. Because of this, Bob may have a tough time climbing
over elevated surfaces while mopping. Make sure to remove Bob’s mop when he is
not cleaning smooth surfaces such as tile or hardwood.
