How do I update a robot vacuum’s room map after rearranging furniture?

First check the exact model, because the right choice depends on its map features. For the Roomba models covered by iRobot’s Smart Maps guide, iRobot recommends a mapping run or a Clean Everywhere mission after furniture rearrangement. For those models, i3/i4/i5 maps need to be deleted and created again; other Smart Map-capable models may let you adjust room dividers, labels, and zones in the app. Options vary by model. [S1]

So don’t delete a map just because a chair moved. Check your model’s instructions first. If your model supports the relevant map edits, use those for a small boundary or labeling correction. If it requires a rebuild, follow its instructions for remapping.

Find the model name or number on the vacuum, its product paperwork, or the manufacturer’s app, then look up that model’s official mapping instructions. Match the model precisely rather than relying on a general app tutorial: features and map controls can differ between models. The cited iRobot guide describes a group of Roomba models, but it does not establish the update steps for every Roomba or any other brand. [S1]

Before changing anything, note whether the app offers map editing and whether the manufacturer says your model needs a new mapping run after a layout change. If the instructions are unclear, ask the manufacturer’s support team which procedure applies to your model and app version. Avoid guessing at button names or menu paths.

Use the manufacturer’s instructions for the specific edit you need. In the iRobot guide, supported Smart Map models can edit room dividers, labels, and zones, but the guide excerpt does not provide the screen-by-screen steps or say that these edits automatically account for every furniture change. [S1]

A practical approach is to identify the mismatch before opening the app: for example, “the divider between the living area and dining area is in the wrong place,” or “this room label needs changing.” Make only the relevant supported adjustment, then check the displayed map against the new layout. If the map still does not reflect the changed space, consult your model’s instructions about a mapping run or broader rebuild. Don’t assume that renaming a room updates its boundaries.

Use this model-first plan:

1. Record the vacuum’s exact model and the rooms or boundaries affected.
2. Open the manufacturer’s official instructions for that model and check whether it supports map editing or requires a new map.
3. If the instructions call for a mapping run, follow them. For the Roomba models covered by iRobot’s guide, a mapping run or Clean Everywhere mission is recommended after furniture rearrangement. [S1]
4. For covered i3/i4/i5 models, follow the instructions to delete the map and run a new mapping mission; for other supported models, use only the map edits their instructions describe. [S1]
5. Review the resulting map and note any mismatch to report to manufacturer support.

Copyable note: “Model: [model]. Layout changed: [rooms/furniture moved]. Map issue: [specific mismatch]. Instructions checked: [page or manual title]. Question: Should I edit [divider/label/zone] or run a new map?” This keeps the support question focused without assuming a particular app layout.
