Cheaper alternative spares are often available for nearly all the iRobot range on Ali Express.

There is a slight difference in parts to the iRoomba ones e.g. the paper filters are visually a little different, or the rubber rollers have a slight change to the dimple designs. They still perform the same imho.

As for the app, just use something like PiHole or another DNS service to block IoT devices, or specific IP ranges or domains. Your hoover will still function just as well.

Far too much built in obsolesence and social media shills serving upgrade culture these days.

Buy. Use. Service til it dies.
