Overall I’m fairly happy with it, in many points an improvement over my older S7 Max. Unfortunately, the mopping which was one of the reasons going for this model is not what I hoped for. The two rotating mops do have some advantages over the older models with one mop. However, the big disadvantage is that it leaves small stripes exactly in the middle of both rotating mops. This would be fine if the middle part would be covered in the next lane by the center piece of one mop. Unfortunately, it seems that the robot has exactly a stride such that the right side in one lane will be exactly the left mop in the next lane, like this the part between both mops will never be properly cleaned and leave stripes. This could be simply fixed by allowing advanced configurations such as stride in the app, but unfortunately the user has no control over this :(
