Z60 poor mopping on edge

Hello

I have a z60. Mopping to the edge is poor. Its stays at least 10cm away from edges. I have made sure collision detection avoidance is off. Please suggest what else i can do.

Thanks

Hello, this robot is equipped with edge sensors and AI recognition system. When cleaning alongside walls, the machine will maintain a certain distance from walls due to sensor measurement deviation and different reflection effects of various floor materials, which is normal.
If you are unsatisfied with the edge cleaning performance, please follow the two optimization tips below:
1.Enter the APP settings and set the frequency of "Bionic Edge Cleaning" and "Bionic Edge Mopping" to the highest level.
2.Turn off "Low Collision Mode" in settings for better edge cleaning effect during vacuuming and mopping.

I have the same issue with my V50, edge cleaning on certain edges is at least 10cm away, how can this be improved (I have to go round my room with a vacuum to clean the edges of an open plan kitchen with no obstacles in it) ! The settings you mention for the Z60 are not available to me for the v50
