I have this robot and I think the app makes it possible. The only thing you need is WLAN to set it up. You can set up a fixed schedule and it works regardless of where the smartphone with the app is located. If the robot gets stuck, it can also be sent to the station by pressing a button on the device. Please note, however, that the robot is relatively maintenance-intensive. It has to be emptied and hair removed from the brush practically every time it cleans. I am therefore considering buying a slightly more expensive model with a tank and possibly self-cleaning.

As Chrigur8 has already said, the thing works perfectly without an app. You can even start the vacuuming process manually. It worked for us for years without an app.

Many thanks for the detailed information.
Best regards
