Excessive vibration or bouncing of the cleaner during operation.

Safety first: Unplug and remove tanks before turning the unit over.

• Clean brush bar: Remove all debris and hair from the brush bar.
• Check straightness: Roll the brush bar on a flat surface; if it wobbles, it is bent and should be replaced.
• Inspect bristles: If bristles are worn more on one side, replace the brush bar assembly.
• Tighten fixings: Ensure all screws securing the brush housing and base are tight.
