Vacuum vibrates excessively in the hand during operation.

Safety first: Remove the battery before inspection.

• Check accessories: Ensure the extension pipe and nozzle are fully seated and locked. Remove them and run the main body alone to see if vibration persists.
• Isolate the source: If vibration disappears without the nozzle, the issue is in the nozzle or pipe. Inspect the brush bar for missing bristles or damage.
• Inspect extension pipe: Roll the pipe on a flat surface. If it wobbles, it may be bent and should be replaced.
• If vibration is in main body: Debris may be stuck on the motor fan or the fan may be damaged. Continued use can worsen damage; have the motor housing assembly inspected and replaced if necessary.
