The exact model code is usually on the machine label, not the marketing name on the box.
Where to look
Unplug the vacuum. Check the underside, back, dustbin area, or handheld body for a rating label. For a robot, check the underside and the app’s device information. Do not remove a battery solely to read a label unless the manufacturer instructions allow it.
What to copy
Write down the entire model code, including letters and suffixes. A serial number identifies one unit, while the model code identifies a product variant. Keep them separate.
Use the code
Search the full code here, then open the manufacturer source beside any fit result. If only a series name appears, use the maker’s support page to identify the exact variant.
A real fit-check example
A Shark IX140 search can lead to filter 616FJ140, but an IX code with a different suffix should be checked against the source list in its own right. Likewise, Dyson's V8 parts flow separates machines by star versus pinch pre-filter; the marketing name V8 is not enough to settle a battery or filter purchase. These are good reasons to copy every character from the rating label before opening a shopping result.
Common question
What if the label is unreadable?
Check the manual, registration account, or maker's support flow. Photograph the entire label for your own reference, but avoid posting a serial number publicly. If you still cannot identify the exact variant, pause the part purchase.
Next step
Use the model and part search with the complete code. A missing result means our catalog has not established a fit.
