How to Fix / Troubleshooting

Safety first: Remove the battery pack before manipulating the power button area.

  • 1. Inspect button movement: Press the button repeatedly with the vacuum off. It should move smoothly and return fully.
  • 2. Check for debris: Blow away dust around the button. Do not use liquids.
  • 3. Temporary workaround: If the vacuum starts only when pressed at a certain angle, avoid excessive force to prevent further damage.
  • 4. Permanent fix: The handle housing must be opened to replace the button or switch on the PCB. This should be done by a technician to avoid damaging the control electronics.
