Sensors
Cleaning Bob’s sensors
Dirt and dust on the bottom and side sensors can reduce bObsweep’s performance.
Regular cleaning of the sensors ensures that Bob keeps working at his best. Use
a soft cloth or a cotton swab slightly moistened with cold water or alcohol to wipe
bObsweep’s surface, around and underneath his belly, especially on the bumper
and floor detection sensors on Bob’s bottom.
Blindfold Stickers
Dark colored carpets or certain patterns
can seem like an edge to Bob’s infrared
sensors. If you notice that Bob stops with
Error 4 (Trouble Nr 4 for Bob PetHair) on
your carpet, you can try ‘blindfolding’
Bob by covering the 4 floor detection
sensors underneath him as shown in the
picture below (circled). The floor detec-
tion sensors are on the front and sides of
Bob’s bottom when you turn him around.
Just make sure Bob is not getting any-
where near stairs or sharp edges when
blindfolded or he can fall.
