The robot vacuum may not run on certain dark or black surfaces.

Because the Infrared ray of anti-fall sensors may be absorbed by certain dark or black colored surface and recognize such area as an edge or a stair. When robot encounters this surface, robot may run away from this surface. No adjustment can be done to correct this behavior.

Reminder: Please keep the anti-fall sensors clean and do not block the anti-fall sensors, as this may create an unsafe operating condition.
