Roomba’s night job track #2
Light trail left by iRobot Roomba during its first 30 minutes of cleaning.
The wall on the right is illuminated by a LED on Roomba’s base, a place where the robot parks to charge its battery after finishing.
As there was almost no furniture in the room, Roomba did quite a nice job cleaning everything but tiny areas in corners that are simply unreachable to it.
Lighting is going from a window in an opposite wall. Basically, it’s just city glowing, no street lamps or any other light sources are nearby.
