Vacuum vibrates excessively or feels unstable in the hand during use.

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

Steps to try:

• Clean brush bar thoroughly: Remove all hair and fibres from the brush bar so that weight is evenly distributed.
• Check straightness: Roll the brush bar on a flat surface. If it wobbles, it may be bent and should be replaced.
• Inspect floor head: Remove any debris stuck in the housing that could cause imbalance.
• Assess motor vibration: If vibration persists with the floor head removed, the main motor fan may be damaged, requiring replacement of the main body.
