Your home layout and size speaks about how much is your income, which usually is a superset of what you could spend in online purchases. Also, should they stick a camera or a very advanced lidar in front of the Roomba, they could build a database of what items their customers have -and don't have- (read: could be pushed to purchase through targeted advertising) in their homes. I expect some more room for Roomba competitors here; certainly I wouldn't want a Amazon branded one even for free.
