Vacuum vibrates excessively in the hand or through the wand during use.

Safety: Remove the battery before working on rotating parts.

• Clean brush bar: Remove the brush bar and clear all hair and debris, especially from one side that may be heavier.
• Inspect roller shape: Check soft rollers for flat spots or deformation; replace if misshapen.
• Test without head: Run the vacuum without the cleaner head. If vibration disappears, the head is at fault; if not, the motor may be imbalanced.
• Replace faulty part: Replace the vibrating cleaner head or, if the motor itself vibrates, have the motor assembly replaced by a technician.
