My robot vac will only operate when connected to the Internet so it's only allowed to communicate when actually in use. As soon as it returns to the charger Internet access is automatically blocked.
Unfortunately the manufacturer has deliberately made this as inconvenient as possible. If communication is blocked for more than a few hours the vacuum loses all maps and will no longer even load saved maps from the Tuya app. To use it the vac must be powered down and the app killed. Only then can a saved map be restored.
It's too bad it's so useful.
