Roomba i3 parts list: match the OEM number
Use this list to identify a replacement, then open its evidence record for the source, region and any exclusions. These are cataloged items, not a complete repair manual or a claim of local stock.
i315020; iRobot UK publishes Roomba i3 as item i315840. Those item numbers identify regional robot listings, while the accessory rows below use US manufacturer listings for the i Series. Check the number on the robot label or in the app and use the matching regional source before ordering; do not treat i3 as a worldwide hardware identifier.
