I picked up a Roborock E4 a few years back, both because it was relatively cheap and a couple thorough reviews indicated it was one of the better devices out there. I initially spent a couple hours trying (and failing) to connect it to the Android app, only to discover (out of frustration) that pressing the start button on the unit would clean just fine! I was absolutely relieved that it wouldn't be uploading anything anywhere, the only "downside" was that I couldn't indicate which areas/rooms to ignore, although I'm not sure that would have mattered much since I constantly move things around. I have no idea if any other models run without smartphone/tablet setup but if so, that would potentially eliminate any privacy issues ;) Maybe it's time to create a public spreadsheet with a list of models that run without a smartphone, and potentially any downsides to doing so...
