Side-by-side check
| Question | Option A | Option B |
|---|---|---|
| Model name | Roomba Combo j7+ | Roomba j7+ |
| Kit 4812261 | Manufacturer-listed | Explicitly excluded |
| Buying check | Retain “Combo” in the search | Choose a kit listed for standard j7+ |
Why the extra word changes the answer
iRobot explicitly includes Roomba Combo j7+ on kit 4812261 and excludes standard Roomba j7+. The two names look close in a short search result, so copy the complete product name from the robot or app before opening a listing. Do not carry the Combo fit claim to standard j7+ or to another Combo model that the source excludes. If the name is uncertain, use iRobot support to identify the exact robot before buying consumables.
A comparison helps narrow the question. It never replaces the manufacturer model list and the label on your machine.
