Hi so sorry to hear about that, I am a robot engineer and have building and working with them for years, I have several roombas, how long have you had yours?
also what model is it?
I've had it for several years and it's a 551
thanks, XXXXX XXXXX happens the robot will need to be serviced by the factory unfortunately
irobot.com will fix this for you
they need to reset some parameters
I wish there was a quick fix for this I really do but thiey need to check it out and have specilized tools to do this
