How to get current room name & (already) cleaned rooms?

[TheDelta]

I couldn't find any specific information, but I would like to use the attributes cleaned_rooms and vacuum_room_name.
They are always null for my Roborock S7 (used_api: xiaomi) and so far I can only successfully use vacuum_room.

My room numbers attribute looks like this:

room_numbers: 
'16': null
'17': null
'18': null
'19': null
'20': null
'21': null
'22': null
'23': null

(I assume instead of null the actual room name should be listed there?)

Is this not supported (yet) or am I missing something?

Not every attribute is supported by every vacuum as maps for some models contain more data than other ones.

Thanks for the quick response. ❤️
Then I'll have to find some workaround for it to rely only on the vacuum_room number.
