My robot has a problem with the charging station, Error 20. The manual says E20 means I am using the incorrect base station. It is definitely the correct one as I only have one and it has worked perfectly until now. I have cleaned the contact points with rubbing alcohol. What's wrong?

    It is possible that the wall adapter unit is no longer working correctly. It should provide 22V (in case you have the possibility to check it yourself with a multimeter- but not everybody has one at home). There is also the less likely possibility that the internal electronics in the robot have developed a fault, but it is most likely the charger adapter. Contact your nearest service office about a replacement.
