Dirt sensors
For a more efficient clean, Bob is equipped with dirt sensors. If Bob reaches a particularly
dirty spot while cleaning, his dirt sensors will activate, the word DIRT will appear on his
screen, and Bob will focus his attention on the spot. Bob's dirt sensors are located on
the back wall of his interior, where the dustbin attaches. To clean the sensors, wipe them
with a soft cloth.
