This doesn’t work

If I “remove” it, I work again.
This only have it with all other items from the vacuum. If I add an other switch for e.g. the lights, I don’t have any issues.

Your sitemap looks normal. What are the [] in the labels for? I didn’t these before. Maybe these cause the errors.

Does adding another item (not miio) work?

[ ] in labels are ordinary enough, this is the state presentation formatter, describing how you would like the Item represented in text.
[ ] is valid for “no thanks, suppress text” which is ordinary enough when used with a Switch type widget.

I’d be looking at what character set the editor is using, sitemaps need to be UTF-8
