Symptoms

  • App shows robot as offline
  • Commands sent from the app don't reach the robot
  • App won't finish setup or pairing
  • Robot works with physical buttons but not the app

Likely causes

  • CommonRobot disconnected from Wi-FiRouter changes, password updates, or signal issues can drop the robot's connection.
  • CommonPhone on a different network than the robotMost robot vacuums need the 2.4GHz Wi-Fi band, and phones sometimes default to 5GHz.
  • 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

  1. Confirm your phone and the robot are connected to the same Wi-Fi network, ideally the 2.4GHz band.
  2. Restart the robot vacuum by powering it fully off and back on.
  3. Restart your router if other smart devices are also having issues.
  4. Update the app to the latest version from your phone's app store.
  5. Check for a firmware update for the robot within the app's settings.
  6. Remove and re-add the robot vacuum in the app if reconnecting alone doesn't work.
  7. If it still won't connect after a full re-pair attempt, contact the manufacturer's support for further diagnosis.
