- PossibleApp or firmware out of dateOutdated app or robot firmware can cause connectivity handshake failures.
- PossibleRouter or app server issueA router reboot loop or a temporary outage on the manufacturer's server can block connection.
- Less commonRobot's Wi-Fi module failureAfter years of use, the internal Wi-Fi chip can fail, permanently disconnecting the robot from apps.
What to do
- Confirm your phone and the robot are connected to the same Wi-Fi network, ideally the 2.4GHz band.
- Restart the robot vacuum by powering it fully off and back on.
- Restart your router if other smart devices are also having issues.
- Update the app to the latest version from your phone's app store.
- Check for a firmware update for the robot within the app's settings.
- Remove and re-add the robot vacuum in the app if reconnecting alone doesn't work.
- If it still won't connect after a full re-pair attempt, contact the manufacturer's support for further diagnosis.
