I also have this question – to provide more context, @Tecnoman is asking about Matter 1.4, which adds the ability to select rooms to clean (I can't post links, so search "What the vacuum robots in iOS 18 reveal about Matter" by Frank-Oliver Grün). The RV30 Max and RV30 Max Plus already support Matter 1.3, which is apparently the same as Matter 1.2 and only has basic start/stop and cleaning modes (vacuum or mop).
