Wipe any remaining water inside the omni station with a dry cloth, then reinstall the washboard.8. Q: What to do if the water overflow sensor electrodes of the Xiaomi Robot Vacuum X20 Max's omni station turn yellow?A: The water overflow sensor electrodes on the omni station are used to detect the water level in the washboard. When the water level rises and is in contact with the electrodes, it begins to drain the dirty water, preventing overflow. Since the electrodes are in contact with dirty water for extended periods, yellowing is normal and does not affect regular use. You can wipe them with a damp cloth before use.9. Q: What to do if the Xiaomi Robot Vacuum X20 Max has recharging issues?A: Recharging issues can manifest in several ways, such as the device not being able to find the omni station, failing to climb onto the omni station, misalignment during docking, or not charging. If the recharging process is functioning correctly, the device’s indicator will turn on and blink in white when it docks properly.If you notice any abnormalities, you can troubleshoot with the following steps:1. Check the power supply to the omni station. Ensure both ends of the power cable are securely plugged in, and the omni station's indicator is steady in white;2. Wipe the charging contacts on both the omni station and the robot vacuum. Dirt or wear can cause recharging issues;3. Check if the omni station's location on the map matches the actual setup. If there's any misalignment, consider repositioning the omni station;4. For first-time use, install the washboard base extender correctly with smooth seams. Otherwise, the robot vacuum can not be able to climb onto the omni station. Wipe any water from the floor and the washboard base extender to prevent slipping which can cause recharging problems;5. If the robot’s movement is abnormal, resulting in recharging issues, clear any hair or debris from the caster wheel and main wheels.Note:1. When using the device for the first time, ensure that it starts its mapping process from the omni station and automatically returns to the station upon completion;2. Avoid placing obstacles too close to the omni station. Ensure that there are no obstacles within 5cm on either side and 1.5m in front of the omni station;3. If the robot vacuum does not start its cleaning cycle from the omni station, it can not find the omni station during the cleaning process. It is recommended to start the cleaning task from the omni station;4. If the robot vacuum is moved during the cleaning process, it can fail to reorient itself when the task resumes, leading to a new task being initiated;5. Ensure the omni station and the floor in front of it are dry to prevent the robot vacuum from slipping during recharging.10. Q: What to do if the Xiaomi Robot Vacuum X20 Max reports a high water level in the washboard?A: 1. Remove the washboard, thoroughly rinse it, and wipe it dry with a clean cloth;2. Check the bottom of the washboard for any blockages and wipe the inside of the omni station with a dry cloth;3. Reinsert the washboard into the omni station;4.

Q: Why does the omni station make unusual noises when using the Xiaomi Robot Vacuum X20 Max?A: 1. The water pump for cleaning the mop can produce a sound as it draws water into the washboard;2. The mop motor assembly causes the washboard to rotate, creating friction and noise;3. The dirty water pump creates a noise. Because it vacuums dirty water from the washboard into the dirty water tank;4. The dust collection fan makes a sound as it creates negative pressure to pull dust into the disposable bag;5. During the drying process, the fan blowing warm air can produce a slight noise.14. Q: Why does the Xiaomi Robot Vacuum X20 Max report a lack of water?A: When the water level in the clean water tank drops to approximately 500ml or lower, the system will report a lack of water. This is to alert you to add water in advance to avoid running out of water, which can affect subsequent cleaning tasks.15. Q: Why are there air bubbles in the water tank of the Xiaomi Robot Vacuum X20 Max?A: During production, a tight protective film is applied to the water tank to prevent scratches on its surface, which can result in a few air bubbles. This is not a defect in appearance. You can choose to remove the protective film or use it as is.16. Q: Why does the Xiaomi Robot Vacuum X20 Max's omni station wobble slightly?A: It is recommended to place the station against a wall on a hard, flat surface. A slight wobble when manually pushed is normal and does not affect the product's normal operation.17. Q: Why are there scratches inside the cover of the Xiaomi Robot Vacuum X20 Max's omni station?A: After opening the station cover, you can notice square-like scratches or glue overflow issues. These are marks from the gating area, which is a normal part of the manufacturing process. We are continuously working on improvements.18. Q: Why does the Xiaomi Robot Vacuum X20 Max make a noise after washing the mop?A: After the mop is washed, it rotates as it retracts, which can cause brief scraping noises with the washboard. This is not a performance issue, and we are continuously working on improvements.
