As the title suggests, I’m in the market for a vacuum that doesn’t phone home, not even for initial setup (if possible). This is my first time stepping into home automation so I’m not familiar with the various FOSS projects in the space. I’m comfortable with modding/rooting the vacuum so throw your suggestions, I’ll research them.

I can also recommend Roborock brand in general because the hardware seems decent and it runs well enough with no internet/smart app required. I’ve not installed Valetudo on mine because the S4 requires some hardware changes that I’m not comfortable making. Other Roborock models are much easier to install.
Good luck!
