Blindfold Stickers
Dark-colored carpeting and certain
oor patterns may seem like edges to
Bob’s ground detection sensors. If you
notice that Bob stops with TROUBLE
NR 04 on your carpet, you may need
to “blindfold” Bob by covering his
ground detection sensors. Bob’s
ground detection sensors are located
on his underbelly, near his bumper.
While blindfolded, Bob will be unable to
detect stairs or sharp edges.
Dirt sensors
For a more ecient clean, Bob is equipped with dirt detection sensors. If Bob reach-
es a particularly dirty spot while cleaning, his dirt detection sensors will activate, the
word DIRTY will appear on his screen, and Bob will increase his cleaning intensity.
