So far I could only see matter support officially announced for the S8 MaxV Ultra.
But when the matter 1.2 standard was announced I read in one of the articles that the S8 Pro Ultra would get it. I have not seen an announcement on that at all.
I would have thought that this would have been a much bigger deal at CES but all the reviews have just mentioned this in passing. I have been holding out until matter support came out and used my cheaper robot vac till about a month ago when it stopped working. I am sweeping daily now and I can't seem to keep my house as clean.
The only one's I have seen with matter support so far is:
-Roborock S8 MaxV Ultra
-Switchbot S10
But more might have been announced in CES that I didn't see.
Switchbot S10 has no matter support yet, just a promise for the future. Also, it apparently won't work directly but need to go through their seperate Hub2
