Excessive vibration in the handle when the brushroll is running.

Safety first: Remove the battery and detach the nozzle.

• Step 1 – Clean brushroll thoroughly: Remove all hair and fibers from the brushroll, especially from one side that may be heavier.
• Step 2 – Check for straightness: Roll the brushroll on a flat surface. If it wobbles, it is bent and should be replaced.
• Step 3 – Inspect bristles: Ensure bristles are evenly worn. Missing sections can cause imbalance; replace the brushroll if needed.
• Step 4 – Tighten nozzle components: Confirm that the nozzle base plate and screws are secure.
