A similar name
isn’t proof of a fit.
We make the evidence visible, so you can make a better choice.
Four compatibility labels
Verified fit requires an explicit source covering the exact part and robot or dock. That may be a manufacturer listing, a manual, or documented physical testing. We do not claim to have tested a part ourselves unless a test is documented.
Seller claimed means a seller states that the part fits. It has not been independently established. Not verified means the evidence is incomplete or conflicting. Does not fit requires explicit negative evidence; absence from an incomplete model list is not enough.
Originality is a separate question
Genuine, aftermarket and unknown describe the part’s origin. A genuine part can still be wrong for your robot. An aftermarket part can be compatible, but that needs its own evidence. A seller’s “original” title alone is not proof.
Check the model, market and dock
S8, S8+, S8 Pro Ultra and S8 MaxV Ultra are separate models. A new generation or a different dock can change the required part. We show market and dock restrictions beside the relationship. Select your market and dock before treating a conditional match as confirmed.
Kits need every component to fit
A kit contains a published list of parts and quantities. Full compatibility requires sufficient evidence for the kit and each component. One uncertain component prevents a fully verified result.
Prices and seller offers
Only admitted, current offers for the exact variant appear. We compare identical packages within the same origin and currency group. An unknown shipping charge is not shown as free. Availability, shipping and the selected seller variant should be checked before ordering.
When evidence changes
A temporary source outage does not automatically erase a previously established relationship. It can be marked for another review. Conflicting evidence remains visible and prevents a confident recommendation for that relationship.
Electrical parts
Battery offers need an additional safety review. Match the exact voltage, connector and supported model, and follow the manufacturer’s servicing instructions.
