If the floor is dirtier after mopping with the Xiaomi Robot Vacuum X20+, please refer to the following suggestions:
1. If the mop pads are already dirty before starting, or if the Auto mop cleaning frequency is set too low, the robot vacuum spread dirt instead of removing it. You need to clean the mop pads before use and increase the mop pad cleaning frequency;
2. The robot vacuum uses stale or contaminated water in the clean water tank can cause the mop to deposit dirty water on the floor. You need to use fresh, clean water and clean the water tanks regularly;
3. Water output might be set too high or too low. Excess water leads streaks and dirt residue, and too little water leads to ineffective cleaning, just smearing dirt;
4. If the floor is too dirty or has too much dust before cleaning, it is recommended to clean the dust off first before using the mopping function.
