Dirt Detect Mode
Roomba features the ability to clean more intensly in dirty areas. When Roomba finds a
particularly dirty area you will see the blue Dirt Detect light come on and Roomba will
change its cleaning pattern.
Roomba uses two sensors to recognize the dirtiest areas.To ensure optimal performance,
you may want to periodically wipe the sensors with a dry cloth. Roomba will sense heavy
debris like pepper, sand, and rice. Roomba will not sense pet hair or dust, but will pick
them up.
