Hello, please follow these steps for troubleshooting:
Make sure the brush cover is clean and securely locked on all sides. Check if there are foreign objects inside the roller compartment. Remove hair and debris tangled around the compartment and roller.
After clearing all obstructions, power off and restart the robot. Let the robot rinse the mop on the base station, then test the mopping function again to check if the error persists.
If the problem remains, please prepare your device SN code, invoice and purchase documents. There may be a hardware fault. Contact our after-sales team via email:
