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 4639309 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 main brush

Match the complete roller assembly, including both end caps, bearing seats and the drive connection. A similar roller length or rubber color does not prove that it will seat in the cleaning head. Single rollers, bristle-and-beater pairs and dual rubber rollers use different decks. Check the manufacturer's supported-model list before transferring a roller between generations.

Remove hair and thread from the user-serviceable brush ends before deciding that the roller needs replacing. Follow the exact robot manual for opening the brush cover and refitting its latches. A brush obstruction error is a symptom: it can come from trapped debris, an incorrectly seated cover or a damaged assembly. It is not automatic proof that a new brush will fix the robot.

For an aftermarket listing, inspect the supplied components rather than only its photograph. Some packs include a roller without the end caps or bearing pieces shown in the original assembly. Ask for the written model list and return policy. This page records manufacturer fit evidence; it does not report comparative cleaning, noise, durability or carpet tests.

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.
