Answer:
1. The error may be caused by obstructed sky view in the current work area, which can weaken GPS signal strength and cause the RTK positioning system to malfunction.
2. If the signal light in RTK reference station show frequent abnormalities (e.g. orange or red) throughout the day, consider relocating and reinstalling it in a better-sited location—ideally with clear, unobstructed sky view.
3. If you’ve recently replaced the RTK reference station, manually scan the QR code located on the bottom of the new RTK reference station using the app. This step ensures it’s properly bound and paired with your robot.
4. If the issue continues after trying all the steps above, please contact our Roborock Customer Service Team for further assistance.
⚠️ Note: If you’ve relocated or replaced the charging station or base station, you’ll need to restart the mapping process for the robot to relearn its boundaries and positioning reference.
