The quality is at the highest level, be sure to try it.
Before that, I used the s5max robot vacuum cleaner, it was stupid when moving from the first floor to the second. This robot does not have this problem. And so they look like two twin brothers. S6maxv is smarter due to the camera.
Got pros:
Less noisy than the old roborok, cleans better, wiping with a wet cloth is clearly better. Smarter himself, less likely to get stuck.
Cons:
Still stuck, and the trash container is small though. The side brush became clogged more often.
