robot keeps stopping charging in dock.

robot keeps stopping charging kn dock. As soon as the robot comes back into its dock it charges 1 or 2% but then it shuts down. I then have to manually connect to the robot by pressing power. I myself have the idea that it does not have a good connection to the connectors of the dock

Hello,
Is the indicator light of the base station on normally? You can try to clean the charging contacts of the charging base and the robot.
