Vacuum missing one spot in kitchen

My L40 Ultra cleans the kitchen well however it always misses one stretch of area by the cabinets. If it extended the mop I think it would be fine but it doesn't. The vacuum is short enough to fit under the cabinet but it stays about 4 inches away. I'm guessing it's the lidar telling it that it's too close or that the upper part of the cabinet is the "wall".  

I have the same issues

Try with collision avoidance mode off

I tried with collision avoidance turned off, and I did the same thing. What I discovered was that the device doesn't fit under the cabinet overhang so it's getting as close as I can in other areas such as under the dishwasher. It performs a maneuver where it rotates about 45° to swing the mop pad into the area under the overhang. It just can't do it in the area where I took a photo.

Hi,
If the height under the cabinet is similar to the height of the radar, to avoid scratching the radar or the radar might recognize this area as a straight wall, causing the device to fail to enter the cleaning mode or deploy the mop.
