Compare every recorded main brush relationship for this exact robot in one place. 1 Fits. The decision applies to the named original item and the written caveat; it does not approve a generic lookalike.
Original category schematic, not a product photograph or dimensional fit diagram. Match the exact item in the linked manufacturer listing.
Fits. The official Narwal AU product page is titled "Narwal Zero-tangling Floating Roller Brush for Narwal Flow/ Narwal Flow 2" and names Flow. No separate manufacturer item number is shown on the page.
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.

Questions about Narwal Flow
Does a listed original part verify an aftermarket pack?
No. Match that pack separately. The original identifier, source market and any model suffix must agree, and seller-only wording remains unverified.
Why can the page show an excluded or unverified item?
Those records explain a known mismatch or an evidence gap. They help prevent an incorrect purchase; neither state has a shopping button.
