Robot vacuum says “Error 2: Open Roomba’s brush cage and clean brushes” and stops shortly after starting.

Safety first: Power off the robot and remove it from the Home Base before servicing. Flip it over on a towel to avoid scratching.

Steps to resolve:

• Remove the brush cage: Press the yellow or green tabs on the brush guard/cage and lift it off.
• Remove brushes: Lift out both main brushes (rubber extractors or bristle/rubber combo depending on model).
• Clean brushes thoroughly: Use the included cleaning tool or scissors to cut and pull hair, string, and carpet fibers from the brush surfaces and ends.
• Clean brush bearings and caps: Remove the yellow/green end caps and bearings from each brush. Clear hair wrapped around the shafts and inside the caps. Ensure they spin freely.
• Inspect brush motor cavity: Look into the brush compartment for debris, small toys, or impacted dust. Vacuum or gently brush out the cavity.
• Reassemble correctly: Reinstall the brushes in their correct positions (matching shapes/colors), reinstall end caps, and snap the brush cage closed until it clicks.
• Reset and test: Press CLEAN to start a test run. Listen for smooth brush operation without grinding or squealing.

When to replace parts: If Error 2 returns quickly after a full cleaning, the main brush motor module or brush bearings may be worn or damaged and should be replaced.
