Trouble Number 04: Edge Sensors
Bob’s four, oval-shaped edge sensors are located on his underside, near his
bumper.
What to do:
Wipe the sensors using a clean cloth, or dust them using compressed air.
If Bob displays Trouble Number 04 while working on dark-colored carpet
or patterned flooring, you may need to deactivate his edge sensors (see
page 76).
