Cordless vacuum produces excessive vibration and rattling when using the motorised floor head, but runs smoothly without it.

Safety first: Remove the battery and detach the floor head.

• 1. Remove and inspect brushroll: Take out the brushroll and roll it on a flat surface. If it wobbles, it is bent and should be replaced.
• 2. Clean cavity: Remove any stones, hard debris, or buildup inside the nozzle housing that could cause imbalance.
• 3. Check bearings: Spin the brushroll ends by hand. If rough or noisy, replace the brushroll or bearing caps.
• 4. Tighten screws: Inspect the underside of the floor head and tighten any loose screws holding the housing together.
• 5. Replace head if needed: If vibration persists, replace the complete motorised floor nozzle.
