If your robot vacuum still follows the old layout after you move furniture, first run a mission that lets it explore the whole home. If that does not correct the saved map, use your app’s map-editing or restore option if your model supports one; otherwise, remap. The exact fix varies by brand and model—some iRobot i3, i4, and i5 models require deleting and recreating the map to make modifications.
Start with the least disruptive fix
- Check the robot and dock position. If either has moved, put it where the saved map expects it before troubleshooting, if practical. Some models use the dock as a localization reference. iRobot advises remapping after a dock move or major home-layout change; Roborock’s initial mapping guidance says to start from the dock and leave it in place while mapping. These are model-specific instructions, not universal rules. See iRobot’s ClearView LiDAR guidance and Roborock’s map-creation guidance.
- Give the robot a chance to explore. In the app, start a mapping run or a clean-everywhere mission, if your model offers one. Open the doors to areas that should be included and clear access to newly available space. A targeted room or zone clean may not search the rest of the home. iRobot specifically recommends a mapping run or clean-everywhere mission after furniture rearrangement or renovation. Its guide says that directed cleaning does not actively search for new space: Guide to Imprint Smart Maps.
- Check for map editing or restoration. If the map is close to correct, look in the app for its map-editing tools. Some models also let you restore an earlier saved map. Menu names and availability depend on the robot and app version.
- Remap if the saved map is still wrong. Use the manufacturer’s reset or delete-map option, then follow the model’s initial mapping instructions. Deleting a map can remove saved room or map information, so confirm what the app says will be erased before proceeding.
Choose the right fix for your robot
| Robot or map system | What the manufacturer guidance supports | Practical implication |
|---|---|---|
| iRobot Imprint Smart Maps | After rearranging furniture or renovation, iRobot recommends a mapping run or clean-everywhere mission. For i3, i4, and i5, its guidance says maps do not update during cleaning; delete the Smart Map and create a new one to make modifications. Source. | Do not expect ordinary cleaning to revise the map on those models. Follow the delete-and-remap process if the layout itself needs to change. |
| Supported iRobot Smart Maps | iRobot describes restoring a previous Clean Map report from History using “Update Smart Map.” It says restoration cannot be undone, although a different report can be applied afterward. A failed mission may prevent recovery; the guidance suggests trying another mapping run, then deleting and recreating the map if necessary. Source. | Consider restoration when a prior report reflects the layout you want. Check the app’s warning before confirming. |
| iRobot ClearView LiDAR models | The cited iRobot guide says these models can respond more readily to moved obstacles and detect new space; it also advises deleting and remapping after major layout changes or a dock move for the models covered. Source. | Whether a small change updates automatically, or a major change requires remapping, depends on the exact model. Check its matching instructions. |
| Roborock | The cited guidance covers initial map creation: enable Map Saving, start at the dock, open doors to rooms to include, and let the robot return successfully to the unmoved dock. It is not a complete post-furniture-change troubleshooting procedure. Source. | Use those setup conditions if you need to create a fresh map, and follow the app’s instructions for your model. |
| Dreame | Dreame documents map editing and restoration; its troubleshooting guidance also describes resetting mapping so the robot remaps during its next cleaning cycle. Map editing and map troubleshooting. | Try an available edit or restore option first; if the map is still skewed or overlapping, follow the model-specific reset instructions. |
When to restore, edit, or start over
Use editing for a small correction
If the map mostly matches the current home and the app provides map-editing controls, use those controls rather than deleting everything. The available edits vary by model; do not assume every app can redraw walls or recognize moved furniture manually.

Restore when an earlier map is better
Restoration can help when the app has a previous map or cleaning report that represents the layout you want. On supported iRobot Smart Maps, the documented route is History, select a Clean Map report, then “Update Smart Map.” iRobot warns that this cannot be undone. Availability and labels may differ across models and app versions.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsRemap after a material layout change or failed recovery
If rooms have changed substantially, the dock moved, or editing and restoration leave the map inaccurate, a fresh map is the clearest reset. A second dock is not a remedy for a furniture-induced map error; iRobot mentions one for people who regularly clean multiple separate spaces, not to repair a changed room layout.

Set up a clean remapping run
For a fresh map, use the setup instructions for the exact vacuum rather than assuming all brands map the same way. Roborock’s initial-map guidance is one documented example: enable Map Saving, begin with the robot at the dock, open doors to the rooms to include, keep the dock in place, and let the robot finish by returning to it. Other brands may use different procedures.
For button-by-button instructions, identify the robot’s exact model and app version. Manufacturer guidance and menu labels can vary between models and change over time.
