You can almost hear the lament of dealing with entitled people in the statement. These are words that originated from having to deal with people who assume that they get free stuff for nothing in return

While this is crystal clear, what isn't clear is what actual robots are officially supported..

For example, the buying recommendations mentions Roborock S8/S8+, but the supported robots page doesn't mention it.

¯\_(ツ)_/¯

It's very clear:

"Please note that this list is exhaustive. These are the supported robots."

https://valetudo.cloud/pages/general/supported-robots.html

The supported robots are the ones on that list, nothing more. The firmware might work on more of them though.

I think in that case they might want to make it clear they are recommending unsupported model.
