Troubleshooting Guide: Can’t Connect Your Roomba to the App?
If you are unable to connect your Roomba to the app, try restarting both the Roomba and your phone/tablet, checking if your Wi-Fi network is stable, ensuring that you have downloaded the latest version of the app, and resetting the Roomba to its factory settings. If none of these solutions work, contact Roomba’s customer service for further assistance.
