Hello,
Thank you very much for your feedback. We truly understand your concern.
This sound is not coming from a fan, as there is no fan inside the product. What you are hearing is the wheel motor. During charging, the wheel motor operates to apply an electronic brake, which locks the wheels and prevents the machine from rolling backward or leaving the charging dock. This behavior is normal, so please rest assured.
At the same time, we are aware that this sound may affect the user experience. The issue has already been reported to our internal software team, who are currently evaluating and working on possible optimizations to reduce the noise.
Thank you for your understanding and patience. |
