Why is there noise from the Xiaomi Smart Pet Fountain during operation?

Question

Accepted Answer

The small noise from the Xiaomi Smart Pet Fountain during operation can be normal, but louder or unusual sounds are often related to water level, trapped air, placement, or parts that need cleaning.
To reduce the noise from the Xiaomi Smart Pet Fountain during operation, please refer to the following methods:
1. Make sure the water level is above the minimum line, because low water can cause the pump to draw in air and create a louder gurgling sound.
2. Reinstall the water tank and top cover firmly, because an unsecured installation can lead to vibration or rattling during water circulation.
3. Place the fountain on a stable and flat surface, because an uneven desk can amplify vibration noise through the body and base.
4. Check whether the filter is installed correctly and whether it is clogged, because restricted water flow can increase pump load and cause abnormal sound.
5. Clean the water tank and internal parts regularly, because hair, debris, or scale can enter the water path and create a grinding or buzzing noise.
6. If the noise happens right after refilling, let the fountain run for a short time to release trapped air, then observe whether the sound becomes stable.
7. If it persists, please contact the after-sales service for further assistance.
