Quick answer
Same checks official stores and repair shops expect — without guessing aftermarket fit. The safest next step is to match the full robot code and OEM SKU on the linked manufacturer source before ordering.
Step-by-step check
- Copy the model printed on the robot or in the app, not the nickname on the box.
- Match the part type and official item number when one exists (example: 4639161).
- Read Does not fit rows. Combo j7+ is excluded from the e/i/j filter pack.
- Buy from the brand shop after the verdict, or a retailer link only if the label is Fits or Probably fits.
Stop when one identifier disagrees
If the model code, dock name, SKU or barcode differs from the sourced page, do not assume the listing is a newer equivalent. Treat it as Not confirmed and check the manufacturer page.
Start with an exact identity
Write down the complete robot model from the underside label or manufacturer app and the printed identifier on the replacement part. Series names, colors and marketplace keywords are useful for discovery but cannot prove a model-part relationship. Keep the source region with the record because a local bundle or suffix can change what is supplied.
Read the verdict and evidence together
A Fits result applies only to the exact pair shown on the page. Probably fits includes a written caveat, Does not fit requires an official exclusion, and Not confirmed means no exact relationship has been established. Open the cited manufacturer URL and read its current compatible-model list before ordering.
Stop conditions during installation
Do not force a latch, trim a filter frame, alter a connector or run the robot with a cover that will not close normally. Recheck the model and part identifiers if anything binds. Batteries, charging docks and sealed electrical assemblies should follow the manufacturer manual or service route rather than improvised fitting.

- Open the dated source instead of relying on a search-result or marketplace title.
- If the local SKU differs, keep the relationship Not confirmed and submit the official regional page.
