If your RoboVac stops with one beep error and a flashing red indicator, please let us know whether the vacuum is running in an empty environment without obstacles, or whether the vacuum is stuck somewhere. Please send us a video for us to better assist you.

If your RoboVac stops with one beep error and a solid red indicator, please try the following:

1. Clean the wheels out, and tap/shake the wheels to make sure they are flexible and can spring back. You can compare one with the other.

2. Check the bottom of the vacuum to confirm it's an "R" or "L" on the problem side. For some models, there isn't printing on the bottom, so you can check the problem wheel is nearer/further to the main power switch.

3. If cleaning from the outside did not help, you can try disassembling the problem wheel to check whether there is anything getting stuck under the wheel or whether a wire is broken.

Kind reminder: please push the cable into the machine when you install the wheel back, otherwise, the motor may wear down any extra slack.

If the troubleshooting does not help, please contact us for further assistance.
