Does the Kobold VR200/ VR300 vacuum cleaner robot drive automatically to the base station for charging when the battery is empty or do I have to tell the Alexa?

When the battery of the Kobold robot is empty, the Kobold robot returns to the base station to recharge itself.

As soon as the battery is recharged, the Kobold robot resumes the cleaning process.

This function is not changed by the connection to Alexa.
