Unique Furniture
Bob is designed to maneuver around furniture of most shapes and sizes, but
certain configurations may confuse him temporarily. Bob may sometimes find
it difficult to clean under chairs with narrow legs, or furniture that is too low for
his bumper sensors to detect. Specialty furniture, such as desk chairs with
wheels or stools with circular bases, may also confuse him for a moment — but
don’t worry, Bob usually finds his way around with time.
Edge Sensors
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 displays
TROUBLE NR. 04 while working on dark-colored carpet, you may need to tempo-
rarily deactivate his edge sensors. To do so, simply hold down the UV button on
Bob’s cover until the 5 bars at the top of his screen flash 7 times and then remain
lit ( see page 61 ). Just remember that while Bob’s sensors are deactivated, he will
not be able to detect edges or stairs!
Main Brush
Bob’s main brush is not designed to clean shag carpet or rugs with long fibers or
fringes. You may remove Bob’s main brush and allow him to vacuum without it,
but he will not clean as effectively.
