Hello,
Regarding the abnormal noise you reported, our technical team has conducted an initial analysis and provided the following feedback:
The sound does not quite seem to be coming from the robot itself. This is because the working components of the robot — such as the roller brush, side brush, LiDAR motor, etc. — operate at relatively high speeds. If it were a fault-related noise or friction caused by a trapped foreign object, the frequency of the noise would typically not be that low.
However, if you have confirmed that the noise only occurs when the robot is powered on and operating, we recommend, to be on the safe side, that you send the robot back to our after-sales service center for inspection and repair.
We apologize for the inconvenience caused. Thank you for your understanding and support!
If you still remember the email address you used for the purchase, you can contact our after-sales support at Email:
