Cordless SEBO vacuum makes loud rattling or grinding noises from the brush head.

Safety first: Remove the battery before opening the brush head.

• Open brush head: Release the bottom plate or access panel and remove the brush roller.
• Remove debris: Look for small objects (coins, stones, toys) inside the housing and around the roller. Remove all foreign items.
• Check bearings: Spin the brush roller by hand. If you feel grinding or hear scraping, replace the brush roller assembly.
• Inspect gears (if gear-driven): If accessible, inspect the plastic gears for missing teeth or heavy wear. Replace the gear module or entire head if damaged.
• Reassemble securely: Ensure the roller is seated correctly in its slots and the bottom plate is fully latched. A loose roller can rattle and damage the housing.
