If your Roomba is cleaning rooms that no longer exist, it may be using an old Smart Map.
This guide explains how to delete an old map on iRobot Roomba and keep your mapping setup accurate in the iRobot Home app.
What an old Roomba map actually is
iRobot Roomba models with Smart Mapping store floor plans after a successful cleaning run.
These maps are used for room names, Clean Zones, Keep Out Zones, and targeted cleaning schedules.
Over time, a map can become outdated after moving furniture, changing the layout, relocating the robot’s base, or using the same Roomba in a new home.
An old map is not always a problem, but it can create issues such as incomplete room boundaries, missing areas, duplicate maps, or cleaning routes that no longer match your floor plan.
In many cases, the fix is to delete the outdated map and let the robot create a fresh one.
Before you delete a map
Deleting a map removes saved room labels, zones, and custom cleaning preferences tied to that map.
If you still want those settings, take a screenshot of the layout or note the room names before you remove it.
- Make sure the Roomba is connected to Wi-Fi.
- Confirm you are signed into the correct iRobot account.
- Check whether the robot uses Smart Mapping, because not all models support saved maps.
- Update the iRobot Home app before troubleshooting.
If the robot is simply losing its map occasionally, the issue may be related to lighting, low battery, a sensor obstruction, or a Wi-Fi/account sync problem rather than a map that needs deleting.
How to delete an old map on iRobot Roomba
The exact menu labels can vary by app version and Roomba model, but the process is similar across most iRobot Home app installations.
- Open the iRobot Home app.
- Select your Roomba from the device list.
- Go to Map, Smart Map, or Maps.
- Open the map you want to remove.
- Tap the settings icon, overflow menu, or three-dot menu.
- Choose Delete Map, Remove Map, or Reset Map.
- Confirm the deletion when prompted.
Some app versions store multiple maps under a map manager screen.
In that case, you may need to open the specific home or floor map first, then remove it from the map list.
If you only see options to edit room names or zones, look for a separate map management or history area.
What if you do not see a delete option?
If the delete command is missing, one of these situations is usually the reason:
- Your Roomba model does not support editable Smart Maps.
- The app is not fully synced with the robot.
- You are viewing a live cleaning map instead of a saved Smart Map.
- The map is linked to an active home profile or multiple-floor setup.
Try force-closing the app, reconnecting the robot, and checking for updates.
You can also verify whether the map exists in the robot’s settings rather than the main cleaning screen.
In some cases, iRobot support recommends removing and re-adding the robot to refresh stored map data.
How to reset a map versus delete it
Deleting and resetting are related but not identical.
A delete action removes the saved map from the app.
A reset action may erase the current map and force the robot to build a new one during the next mapping run.
Use delete when the map is clearly outdated or tied to the wrong layout.
Use reset when the robot is still in the right home but the floor plan is inaccurate, incomplete, or corrupted.
If your app offers both, read the prompt carefully so you do not lose a map you meant to keep.
How to create a new accurate map after deletion
Once the old map is removed, the Roomba needs a clean mapping session to learn the space again.
The best results usually come from starting with a prepared home.
- Pick up loose cords, rugs, and small obstacles.
- Open interior doors if you want those rooms included.
- Place the Clean Base or Home Base in a stable location.
- Charge the robot fully before mapping.
- Run a dedicated mapping job if your model supports it.
After the new map is created, open the app and check the room boundaries.
Edit room names, set Keep Out Zones, and save any No Mop Zones if your device supports both vacuuming and mopping.
How to manage multiple maps in iRobot Home
Many newer Roomba models can store more than one map, which is useful for multi-story homes.
If you are trying to delete an old map on iRobot Roomba, make sure you are removing the correct floor plan and not the active map for another level.
Look for labels such as Home, Floor, or Map Name.
If you moved to a new house, it may be easier to clear all saved maps and start fresh rather than editing the old layout beyond recognition.
For homes with several floors, keep clear names so you can identify each map quickly.
Troubleshooting common map problems
If deleting the old map does not solve your issue, the problem may be somewhere else in the mapping workflow.
Roomba keeps making duplicate maps
This usually happens when the robot is moved between floors without the app recognizing the transition, or when the base station location changes too often.
Keep the base in one place and ensure the robot completes a full mapping pass.
The map disappears after cleaning
Check battery health, wheel movement, and sensor cleanliness.
A weak charge or blocked sensors can interrupt mapping and cause the robot to behave as if it lost the saved layout.
The map looks distorted
Large furniture changes, mirrored surfaces, low light, and closed doors can all alter how the robot reads the environment.
Rebuild the map after significant home changes for the most reliable result.
When a full robot reset may help
If the app refuses to delete a map, the robot does not sync correctly, or settings keep reappearing, a broader reset may be worth considering.
This can involve removing the robot from the iRobot Home app, signing out and back in, or performing a factory reset according to the model’s manual.
Use this option carefully, because it can erase more than the map.
Saved schedules, Wi-Fi credentials, and preferences may also need to be reconfigured afterward.
For most users, deleting the old map directly is the better first step.
Best practices for keeping Roomba maps accurate
Good map maintenance reduces the need to delete and rebuild maps frequently. iRobot’s Smart Mapping system works best when the robot can clean in a consistent environment.
- Keep the charging base in the same place.
- Avoid moving the robot manually between floors unless the model is designed for it.
- Re-map after major furniture changes.
- Keep wheels, brushes, and sensors clean.
- Update firmware and app software regularly.
When the map matches the real layout, room-based cleaning, zone cleaning, and custom schedules become much more reliable.
That is especially important for households that use the Roomba as part of a routine smart home setup.
Why deleting an old map can improve cleaning performance
An outdated map can cause the robot to waste time navigating incorrect boundaries, miss room sections, or fail to honor custom zones.
Deleting the old layout gives the Roomba a chance to learn the current floor plan from scratch, which often improves navigation accuracy and cleaning consistency.
If your robot has been acting as if your home changed shape overnight, the simplest fix may be to remove the stale map and rebuild it cleanly.
