Question about iRobot Roomba i7

Hello M.landolt
Thank you for your question. As already answered correctly, the Roomba i7 cleans even without a wifi connection. This is what the three buttons on the robot itself are for. CLEAN to start the cleaning, a HOME button so that it returns to the station and also a button for spot cleaning at a desired location on 1 m2. We hope we have been able to help you, otherwise feel free to contact us again.
Best regards,
Your iRobot Team

you can run it just like that without wifi and app. but you can't make any settings etv.
