Many errors disappear after a restart. Turn the robot off completely, wait 10–15 seconds, and restart it.

If the error remains, a reset often helps. Caution: This deletes all maps and settings. Depending on the model, press and hold the appropriate button for 10–15 seconds, then set up the robot again.

Errors can also be caused by software issues. Update the app and the robot’s firmware to fix known bugs.

If the error message continues to appear, there may be a hardware problem. In this case, a more involved repair may be necessary. Contact customer support or the retailer.
