How to Fix Narwal Map Rooms Merging After Remap
- insufficient boundary contrast
- doorway transition ambiguity
- map save conflict after quick edits
Problem Description
After remapping your home with the Narwal robot, rooms that were separate before now merge into one large zone. This happens when the robot cannot clearly detect walls or doorways between rooms during the mapping run. Edit room boundaries one at a time in the Narwal app — split merged zones using the room divider tool and verify after each change.
Why This Happens in Real Homes
Why this happens in real homes usually comes down to environment and timing, not instant hardware failure. After remap, separate rooms merge into one zone unexpectedly. The pattern people actually report is Two rooms become one, zone cleaning inaccurate, and boundaries disappear after save
The most common real-world triggers are insufficient boundary contrast, doorway transition ambiguity, and map save conflict after quick edits. The fix is most reliable when the sequence is followed exactly: Recreate boundaries step-by-step, then Improve transition clarity, then Validate zone cleaning targets. After the repair, run multiple command and automation checks so the issue does not reappear later in the day.
Symptoms
- Two rooms become one
- zone cleaning inaccurate
- boundaries disappear after save
Recognize these? Here's what usually causes it.
Common Causes
- insufficient boundary contrast
- doorway transition ambiguity
- map save conflict after quick edits
Most fixes happen in the first 3 steps.
Do not batch-edit many room boundaries before confirming each save outcome.
Tools & Requirements
Step-by-Step Solution
Clear the Map and Start a New Mapping Run
In the Narwal app, go to your robot's map settings and delete the current map. Send the robot on a new mapping run by starting a full clean of the entire home. Before the run, open all interior doors and close exterior doors. The robot maps as it cleans, so it needs unobstructed access to every room during this run.
Make sure Clear Room Boundaries
The Narwal robot detects room boundaries by identifying walls, doorways, and narrow passages. If a doorway is too wide or there is no clear boundary between two rooms (open floor plan), the robot may merge them into one zone. Temporarily place a physical barrier (a box, a piece of furniture) at the boundary point during the mapping run to help the robot detect the division.
Edit Room Boundaries One at a Time
After the mapping run completes, open the map editor in the Narwal app. Use the room divider tool to split merged zones. Draw a divider line across the boundary between the two rooms. Save and verify the split worked before making the next edit. Making multiple boundary changes at once can cause conflicts that re-merge the rooms.
Name and Lock Each Room
After splitting rooms correctly, name each room (Kitchen, Living Room, Bedroom, etc.) in the Narwal app. Locking room assignments prevents the robot from re-merging them during subsequent cleaning runs. Check the map after the next 2-3 cleaning runs to confirm the boundaries hold.
Avoid Remapping Unless Necessary
Each remap creates a new map from scratch, which risks the same merging problem. Instead of remapping, use the map editor to make incremental changes to the existing map. Only remap if you have significantly changed your floor layout (moved furniture, added walls, changed door positions). Minor changes should be handled through editing.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Stable room segmentation should be validated with zone-clean tests after remap.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
