Hello, I’m very happy overall with my x40 ultra.
Although, most of the time the side brush does not work, I have made sure all the settings are correct, reset the robot, deleted and reinstalled the app, cleared the cache, all these things many times. But most of the time the side brush does not work! I have tried to upload videos but this forum will not let me. “Undefined” error appears.
Please, dreame support get in contact with me.
I'm sorry for the bad experience. The side brush is not working due to the fact that it may need to be repaired, so you will need customer service to help you out. In the app, select Me > Help & feedback > Contact us, and you will be able to contact customer service.
Thank you for your feedback! Currently, a single video upload cannot exceed 50MB. I have shared your request for larger video uploads with the development team. Please feel free to share any additional suggestions about the forum or the product.
