Why are there watermarks after mopping with the Xiaomi Robot Vacuum 5 Pro?

When using the Xiaomi Robot Vacuum 5 Pro for mopping, it is normal to notice some watermarks left on the floor. These marks appear as the moisture gradually evaporates and are not a sign of malfunction. The extent to which these watermarks are visible is influenced mainly by the type of flooring and the surrounding lighting conditions.
For your reference, more detailed guidance on how to reduce watermarks is provided below:
  1. Regular cleaning helps maintain floor hygiene and prevents watermarks from becoming noticeable.
  2. A fresh and clean mop pad ensures better water absorption and reduces streaks or marks.
  3. With continuous cleaning, the overall cleanliness of the floor improves, and watermarks become less visible over time.
