Question about Dreame X50 Ultra Complete

Hi, Unfortunately I often read that the rollout was too early and the robot performs very strange actions, obstacle detection doesn't work or that the app is very bad. In general, the opinions on the net are clearly peppered with the fact that the robot is very bad. If you ignore the clear Marketing poses. As this is the only robot so far that can overcome the many thresholds (up to 5cm) in my home, I would like to buy it. However, I don't want to spend so much money on a machine that has so many faults. For the money, the machine has to do what it promises. Unfortunately, I can't see any mention from the manufacturer that they have recognised the problems or that they want to do something about them. Do you have any information with a guarantee for a comprehensive firmware update? Otherwise I'm waiting for the competition... There isn't much competition at the moment when it comes to climbing robots.
