My Roomba 560 seemed shy as it was backed into a corner with a dead battery every time I came home. So, as I had done many times before, I cleaned all the LED sensors under the bumper and fitted a new battery. No change. I eventually found this site about the nine beep dance of death. Ah, more dust in the sensors, I thought. Testing showed the faulty right bumper switch. Taking it apart I was pleasantly surprised by the use of optical rather than mechanical switches. Still, dust could still be a problem.
