Mostly great but a couple of annoying things

It works mostly great. I am very impressed. There are some things that I cannot understand.

1. Some edges of furniture are cleaned up to the border, some not. Why?

2. Sometimes it seems lost and wanders around before finding the threshold between rooms.

3. There is one threshold that it can pass through, but keeps forgetting how, so sometimes it works at once, sometimes after 5 tries, sometimes after 10, and sometimes it just doesn't make it. Why does it not just learn the correct way and location and repeats it everytime instead? It is quite annoying.

Other than that very happy with how it cleans and avoids obstacles.

Dear DQ906832,

hello，Regarding the corners that were mentioned as not being cleaned: Our machine uses the world's first bionic mechanical arm with a strategy of edge cleaning by extending the mop outwards to clean corners. You can adjust it to the extreme cleaning mode in the app.
Please clear the floor of excess debris or cables and observe under what circumstances the robot gets lost.
Concerning the threshold that requires multiple attempts to cross: To improve efficiency in overcoming obstacles, we will first attempt to directly cross low thresholds when identified. If it cannot be crossed after several attempts, it will switch to using the mechanical feet to cross, and this threshold will subsequently always be crossed using the mechanical feet. Multiple attempts to overcome the obstacle will only occur once.

Thank you for your recognition of the X50 Ultra Complete.
