I bought it as an alternative to xiaomi, and compared it with it: - ecovacs clearly better. Plus boost mode on carpets - I thought that xiaomi had bad software, but it turned out that ecovacs had it much worse - Xiaomi's lidar is better. He is less likely to hit obvious obstacles. Most of the problems of this vacuum cleaner are clearly software. But like most Chinese devices, there are no ates and are unlikely to be.
