Ever since I installed them (which was a problem as the brushes didn't match - I had to drill out the center to get the screw in) I've had a TON of "dirt detection". " Events that cause my iRobot to spin in circles. Then the run time is reduced to 15 minutes. Real brushes are a bit longer than the real ones and I think this causes the machine to become confused. Trust me - I hate buying OEM stuff but I don't see any other alternative.
