Vacuum vibrates excessively when the brush head is on the floor.

Safety first: Remove the battery pack and detach the floor nozzle.

• 1. Remove brush roll: Take out the brush roll and clean all hair and fibers from the entire length, including end caps.
• 2. Check straightness: Roll the brush on a flat surface. If it wobbles, the shaft is bent and the brush roll should be replaced.
• 3. Inspect brush strips: Ensure all bristle strips are intact and evenly worn. Replace the brush roll if any strip is missing or severely worn.
• 4. Clean nozzle cavity: Remove any packed dust or objects from one side of the nozzle that could cause imbalance.
