I used Valetudo on my early Roborock model and it worked great for many years. Unfortunately, the battery gave out and it's somehow DRMed, so even though everything else works fine, the vacuum refuses to work because it doesn't like the new battery.

It's the worst kind of e-waste, it's only waste because someone decided I should buy a whole new vacuum when the battery dies, but Valetudo is otherwise good. Just never try to look for support at all.
