  1. Hi there,
    I tried every possible option to troubleshoot my Eufy Robovac 35c /T2117 and wasn’t able to resolve the following problem:
    – solid red start/stop button light is on while it is parked in the charging station

    My troubleshoot option I checked:
    – power light (white) is on at docking station
    – switched power off and on (including some minutes rest)
    – cleaned any brushes and rollers
    – checked if all wheels are turning
    – cleaned charging connectors on docking station and robovac
    – opened battery section, disconnected battery and inserted it again
    – changed to another power point in the wall to charge robovac

    Am I missing an option or will I have to purchase a new battery?

    Regards
    Mandy
