What to do if there are unusual squealing and high-frequency noises that occur when cleaning the mop pad on the Xiaomi Robot Vacuum 5 Pro?

If you notice unusual squealing or high-frequency noises while the Xiaomi Robot Vacuum 5 Pro is cleaning the mop pad, there is no need for concern. These sounds are not signs of malfunction but are instead related to the cleaning mechanism itself. After the mop pad is washed, it rotates and retracts, and during this process, minor scratches can occur on the washboard, producing occasional short-term abnormal noises. Additionally, the high-frequency noise mainly originates from the friction of the gears in the dual swing arm system.
To address this issue and reduce the noise, you can take the following steps:
  1. Enable the hot water wash function, which effectively eliminates the squealing sound.
  2. Replace the washboard if the noise persists, as a new one will reduce friction and improve performance.
