Issue meaning
What this issue means
The robot leaves some areas or corners uncleaned even though they appear reachable.
Start here
First checks
Allow the robot to continue cleaning so the map can update. Tidy small surrounding objects and complex chair or table-leg arrangements that may be interpreted as walls or obstacles, then run the area again.
Inspection
Area to inspect
Map accuracy, local obstacle layout and tight furniture-leg arrangements around the missed area.

What to do next
Treat this first as a mapping and environmental behavior issue. A missed corner alone does not justify replacing navigation sensors or drive components.
