If there are water marks after mopping the floor with the Xiaomi Robot Vacuum H50 Pro, please refer to the following steps to troubleshoot:
1. If the water output level for mopping is set too high in the Xiaomi Home App, it can leave residual water marks after mopping. You can adjust the water output level within the Xiaomi Home App.
2. If the mop pad is not cleaned for an extended period, its water absorption will decrease. Please clean or replace the mop pad regularly.
3. The flooring material also influences the effectiveness of mopping. Floors with smoother surfaces are more prone to water marks. You can select an appropriate mopping mode based on the floor material to minimize the issue of water marks.
4. It is recommended to empty the dirty water tank on the omni station immediately after mopping.
5. If this phenomenon becomes increasingly severe, please contact the local official after-sales service center for further assistance.
