Roomba i8 Parts & Replacement Parts
CompatRef tracks Roomba i8 compatibility by exact model and component, including filters. A manufacturer series-level statement covers iRobot i8 compatibility with High-Efficiency Filter, 3-pack for Roomba e, i & j Series (SKU 4639161). Compatibility with Edge-Sweeping Brush Module (for e/j series, and i-series before July 15, 2024) (SKU 4759005) depends on whether your unit was purchased before 2024-07-15. iRobot's own listing states this side brush module fits i-series robots only if purchased before July 15, 2024. Check your unit's purchase date, not just the model name. Evidence scope: conditional. Compatibility with Unidentified i-series side-brush replacement is not confirmed; see its evidence below.
Compatibility varies by part. Being in the same series does not mean every part is shared — check each part below individually.

Battery information from iRobot
iRobot's battery compatibility chart names Roomba i8 in the compatibility entry for battery SKU 4706313. The chart words that entry as a series list ("Roomba j6/j6+, j7/j7+, i4, & i8 Series Robots") and does not specify a regional market or purchase/manufacture-date conditions. This note does not state a battery capacity. It is a reference to the support chart, not a current purchase recommendation or a guarantee for every regional or hardware variant. Replacement instructions are not covered here.
