I called and the iRobot center troubleshot over phone. They said docking station. Now 62 dollars later still not charging. Checked new battery and dock with volt meter only 5.4 volts Has new battery also. Still dealing with it. Probably going to replace with something else. Not used that much and sat for a long time. I will try another company product maybe have better results.
