How this part page is researched

Each model above has its own verdict, note, region scope and manufacturer URL. A Fits label means the manufacturer lists the relationship; it does not claim a VacPartFit physical test. Unknown is never converted into a compatibility recommendation.

Ordering checklist

1. Copy the robot model from its nameplate or app.
2. Match SKU S8 Max filter on the manufacturer page.
3. Read exclusions for Combo, Plus, Max, Ultra and regional variants.
4. For batteries or electrical parts, follow the manufacturer safety instructions.

Physical checks for this filter

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.

Filter grade, HEPA wording and claimed particle capture are separate questions from physical fit. This catalog does not test filtration efficiency or confirm a seller's laboratory claims. Compare those claims with the documentation for the exact replacement product. A compatible frame alone does not establish that an aftermarket filter performs like the original.

Dimensions and generation changes

Exact dimensions are not recorded in the evidence dataset. The schematic is not to scale; check the original listing or ask the manufacturer before buying on measurements.

Use the grouped model verdicts to see the recorded generation boundaries. A missing sibling model stays unverified. A kit component without its own published item number is identified by the official bundle contents, not a made-up SKU.

Questions before checkout

Is this a barcode lookup?

A manufacturer SKU and a retail GTIN are different identifiers. Only separately sourced barcodes are accepted; a number printed in an Amazon title is not a verified barcode record.

Who verified these relationships?

The source and relationship review dates are available in each linked model-and-part section. Editorial responsibility rests with Feroz Sheikh. The catalog does not claim hands-on tests unless a page separately documents one.
