In The End, My Neighbors And I Chose 360 S6 Pro Robot Vacuum Cleaner.
Advantages:1. It's very smart, and the noise is within my range.2. The battery life is long. My house is small, and after the whole house is swept, there is still 85% of the electricity.3. The effluent is uniform.4. Getting rid of difficulties is easy, but it is not easy to get stuck. It can be competitive even in a more complex environment.Disadvantages:There is a harsh friction sound when cleaning tiles, but it is only there that the sound occurs. I suspect it may be caused by the uneven floor of my house.Overall, 360S6 Pro is definitely worth getting. My neighbor bought an ECOVACS Robot Vacuum Cleaner and later replaced it with an S6 Pro.That's what I really feel.
