Any ideas?
Sorry to hear that you are having problems with your Roomba. The robot does not turn on at all? Does the Roomba do anything once you press the clean button? Does it try to start or provide you with an error code or series of beeps? This can certainly help us determine the issue with your robot.
If it is completely dead and will not turn on with a battery that works in another robot, we suggest to verify the contacts for the battery inside the robot. Have you tried charging the robot by plugging the charger directly into the side of the robot without using the home base? Have you tried with the charger of the other robot in case the charger is defective?
If it still does not charge from the side with the charger and battery that are proven to work in another Roomba, it is possible that there is an issue with the robots motherboard.
