Not sure about iPhone, but on Android, the permission to let apps pair things in surroundings using BT/WiFi is included in the location permission. You can't pair anything with an app unless you turn the location on. Main feature of the Roomba app is to pair a vacuuming robot using phone's wifi and a special wifi network between phone and vacuum. So while it's not a perfect solution to block you from going further, you can't really be that paranoid about them asking for that access. And ofc, I'm sure your location flew to the iRobot servers along with your other details that could've been scraped from starting the app on your phone. edit: added paragraphs for readability.
