Phantom areas can arise from reflections or a distorted mapping session. Check whether the apparent room aligns with glass, a mirror or an open door.

Start with these checks

Compare the map with the physical boundary and note reflective surfaces.
Correct obvious environmental causes and restore a known good map if available.
Remap only when the manufacturer's process and the current map condition justify it.

What this looks like at home

A narrow duplicate corridor behind a full-height mirror should not become a cleaning zone.

Give the robot a consistent starting point

Check	What matters
Starting point	Use the model’s recommended localisation procedure.
Selected map	Confirm the correct floor and room selection.
Physical route	Check doors, furniture and the return to the dock.

A mistake to avoid

Do not delete a useful map before checking whether a backup or restore option exists.

Buy a part only after identifying the cause

Check the exact model and part reference before buying. If cleaning resolves the problem, a replacement may be unnecessary.

What the result tells you

Check whether the phantom room affects actual cleaning before making large map changes. A visual oddity that never changes the route can be less urgent than a false area that repeatedly attracts the robot.
