I have an different model, but:

Control of the device requires an iOS/android app and communication takes place via the internet.

My model has a camera in order to map its surroundings.

The app makes a map of the space, separated in rooms, and thus possible to request or schedule the cleanup of a specific room or zone. I often start the cleaning process while not at home.

Because the morons making the product think you need to use it while away from home, which is also conveniently allowing them to send data to their servers all the time. I personally never do, so a bluetooth connection would be sufficient, but they don't give you a choice.
