Myster - my robot vacuum cleaner moves during the night from it's charging base - how?

[Soffit]

This will sound strange but it often moves to another room altogether so several meters off the base and around a complicated route. I've never caught it in the act. It often moves towards the front door. The charging base is typically switched off as I only charge it when I want to do a long clean. The funny thing is that it does not do this at all during the day. I don't think my neighbour has one with the same remote control as I hear her loud, traditional vacuum cleaner and she is not very tidy anyway. Does anyone else have any experience of this?

Its because it's looking for the base. The reason it's only doing it in the night is because the battery has discharged through the night to a certain level and hes said, oh better top up and trots off to look for the charger

Came to say the same thing as saw how one escaped a Travelodge in the news earlier!
They're rebelling, I'm scared

Can't you turn the actual vacuum off? Mine has a switch underneath.

@Sunbird24

Wouldn’t survive very long outside though - nature abhors a vacuum…

This is one of the best things I've read on MN is forever. Kudos.

Why do I feel sad that it's searching for the charging point and can't find it? Poor thing ☹️
