The fan wheel on some Xiaomi Smart Air Purifier wobbles during operation

The fan wheel in the Xiaomi Air Purifiers is a crucial component responsible for drawing air into the air purifier and distributing it through the filtration system.
While the air purifier is running, you can observe the device at different speed settings. If there is no abnormal shaking or noise affecting the overall performance, then it is a normal occurrence. Due to manufacturing tolerances in the motor and fan, there will be slight wobbling when the fan operates at low speeds, which is a normal phenomenon and will not cause any other malfunctions. You can use it with confidence.
