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.

Physical checks for this mop pad

Match the mopping system before comparing cloths. Flat sliding pads, rotating discs and roller mops attach differently; a vacuum-only body cannot gain a mop function by adding a cloth. Keep the exact Combo, Hybrid, Ultra or Omni suffix from the robot label. Check the plate or mount named on the manufacturer source as well as the robot family.

Follow the model manual for removing, cleaning and drying a reusable pad. Disposable pads should not be treated as washable replacements. A pad that is installed incorrectly or heavily soiled can change water distribution and floor contact without proving that the robot's pump has failed. Avoid adding cleaning fluid unless the manufacturer explicitly permits that product for the robot and station.

For an aftermarket pack, check dimensions and attachment details against published specifications; when no dimensions are documented here, use the manufacturer's listing rather than an estimated drawing. Texture and thickness claims are not verified performance results. VacPartFit records fit evidence and exclusions, not floor-safety or stain-removal testing.

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.
