Roomba 800 Error 2 reports extractors that cannot rotate. Open the frame and clear both rollers and end caps correctly. Treat the displayed pattern as a diagnostic clue, not as proof that a module must be replaced. Keep the robot on a level, well-lit surface and change one condition at a time so the result remains meaningful. What the alert means: Hair, fibres or packed debris are preventing one or both dual extractors from rotating under load. What to distinguish first: Check the roller grooves, square and hexagonal ends and end caps; a clean centre can still hide a jam at the ends. 1. Confirm the exact symptom — Hair, fibres or packed debris are preventing one or both dual extractors from rotating under load. 2. Prepare safely — Power the robot off, remove it from the dock and place it upside down on a protected table. 3. Apply the official check — Open the extractor frame, remove both rollers, clear hair from their grooves and end caps, then reinstall in the marked positions. 4. Interpret one retest — Turn both extractors by hand before closing. If Error 2 returns immediately, stop rather than forcing the drive. The official iRobot procedure identifies this exact symptom and supports the checks above. Remove loose hair with a dry tool only; never wet the contacts, wheel wells or motor modules. Stop if a wheel, extractor or actuator remains locked after cleaning, or if the same error returns after one reboot.

Next step
Repair, replace a part, or arrange a diagnosis?
Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.
Resolve it without buying anything
Complete the 4 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.
Replace only the confirmed part
If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.
This guide does not identify a replacement part. Do not order a generic component from the symptom alone.
Arrange a diagnosis before replacing the appliance
Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
