The Max kit supplies a unibody filter rather than the non-Max filter-and-foam combination.
What is actually verified
The records below describe the manufacturer-listed original items, including exclusions. They are not tests of unnamed third-party products. An aftermarket listing has to be checked separately against the exact model code 11S Max and the original identifier.
FitsOfficial manufacturer listing
eufy Max/G official kit filter
Original category schematic, not a product photograph or dimensional fit diagram. Match the exact item in the linked manufacturer listing.
Fits. The manufacturer explicitly lists 11S Max. Fit applies to the official kit or the component supplied in it. Non-Max models are explicitly excluded.

What to require from an aftermarket listing
Robot identity
eufy RoboVac 11S Max · 11S Max
Complete model and all suffixes, not only the brand.
Part identity
Exact published identifier or clearly labeled bundle component above.
Actual item identity and a written reference to the original; a borrowed photo is insufficient.
Scope and exclusions
The original Max/G kit expressly excludes non-Max 11S.
Written confirmation of the same generation and caveats; omitted exclusions remain unverified.
Performance
No VacPartFit physical test claimed.
Independent test evidence for filtration, pickup, noise or durability claims.
Returns
Check the current manufacturer store terms.
Check seller returns before opening or fitting the replacement.
When the cheaper pack is difficult to compare
Ask whether the item is the correct unibody assembly. A similar robot height does not verify a filter frame.
A replacement filter has to seal against the correct dust-bin housing. Match the frame outline, tabs and sealing edge as well as the printed identifier. A listing that mentions the robot brand without the complete model is not enough. A foam-and-paper filter assembly and a unibody filter can belong to different generations even when both are sold under the same family nickname.
Check the manufacturer's cleaning instructions before adding water. Washable describes a specific filter, not every filter sold for that brand. A damp filter can restrict airflow and trigger a warning that resembles a failed part. Let a washable item dry for the period stated in its manual; replace torn media or a damaged seal instead of forcing it back into the bin.
Decision before buying
Use the original record as the identity reference. If the seller cannot substantiate a conflicting model or part number, leave that aftermarket relationship unverified and seek a documented match. A manufacturer fit label does not establish seller authenticity or comparative product performance.
Search results · No separate OEM number published. Match the exact model, kit contents and region; a search result does not confirm fit. Check compatible models before ordering.
