Step 1: Confirm the voltage requirements in the United States and Japan

Step 2: Confirm the voltage requirements in European countries

Step 3: Check the robot and the Uniclean™ Station

If your S1 Pro's Uniclean™ Station triggers an "EB02" error, it indicates that there may be a mismatch between the base station's voltage and the wall outlet's voltage.

Please follow the troubleshooting steps below to solve the issue.

Step 1: Confirm the voltage requirements in the United States and Japan

1. Please note that the standard voltage in the United States and Japan is 110V. However, certain high-voltage home appliances, such as electric ovens and dryers, may need to be connected to 240V outlets.

2. Please check whether the specific outlet that the Uniclean™ Station is connected to supplies voltage in the range of 100V to 140V. If the wall outlet does not supply voltage in the range of 110V to 140V, please try another wall outlet and check if the error persists.

3. Upload logs for us to conduct further analysis. Please launch the eufy Clean app > Settings > tap the "S1 Pro" icon > Activity Log Upload > Copy Device Information.

Step 2: Confirm the voltage requirements in European countries

1. Please note that the standard voltage in European countries is 220V.

2. Check whether the Uniclean™ Station you are using is designed for the US market with the 110V requirement, instead of the 220V requirement for European countries.

3. Please check whether the specific outlet that the Uniclean™ Station is connected to supplies the required 220V.

Step 3: Check the robot and the Uniclean™ Station

If you have already confirmed that the voltage supplied by the wall outlet that the Uniclean™ Station is connected to matches the base station’s voltage requirements, but the error persists, please provide the Serial Number (SN) of the robot and the Uniclean™ Station to us to conduct further analysis.
