I’ve got a Eufy RoboVac 30 and until reading this post it didn’t even occur to me to see of there’s an app. Turns out there is, but we’ve never used it and never connected it to our wifi. We just hit the button to turn it on and it works just fine. It came with a remote that we can use to set a schedule but as far as I know it has no way to call home.
This is exactly what I do. It lends itself to something like ‘prefix_specific-info_version’ which is both sortable and easy to read.
