not mopping close near wall and legs

As you can see from the attached picture, the robot does not clean within 1cm of the table legs and sometimes even the wall, leaving a fairly large space, around 5cm. How can this be solved?
PS. I have reset it, i rescan the floors,i have the last firmware 4.3.9_3454.

Hello,

Regarding this issue, please wipe the edge sensor on the right side of the robot with a soft, dry cloth. Ensure the edge sensor is not obstructed by any obstacles/objects.

Then turn off the anti-collision mode and see if the situation improves.

Go to the three dots in the upper right corner – Floor Cleaning Settings – Collision-avoidance mode

Also, please set the mop's outward spread frequency to "High Frequency".

If the device still cannot clean along the edges, please contact our after-sales department for further assistance.
