Roomba i3 Error 2 — Clean the extractors
Symptom: Robot stops, beeps twice / says to remove and clean the extractors. The Dual Multi-Surface rubber extractors may be stalled or struggling to turn. Likely root causes: Hair/string wound at the extractor ends or under the yellow bearing caps (still happens even on tangle-free rollers); Debris or a foreign object (sock, cord) jammed in the extractor bay; Worn or torn rubber treads, or a missing or damaged bearing cap; Extractor frame not latched after cleaning Next steps if owner-level checks fail: Extractors still stall after cleaning — replace the extractor set (~$25–$45); Extractor motor hums but rollers don't turn — gearbox/motor service; contact iRobot Customer Care 1-877-855-8593
