Yeah I almost installed it, ripped apart my vacuum, just to realize there are many different roborock S7 versions with different SoCs, and my variant wasn't supported. Also roborock doesn't even support scheduled cleaning without cloud :(
Yeah, I have a Roborock S7 MaxV I bought about two years ago and was hoping I could put open source firmware on it but after some searching I learned that Roborock makes a lot of similar but different flavors within a generation like S7 and they can be quite different. Unfortunately, it appears my MaxV flavor of the S7 isn't rootable.
