Possible Causes
Loose battery contacts in handle, Broken wire in pivot joint between handle and motor unit, Cracked solder joints on PCB, Worn connector between tube and nozzle
How to Fix / Troubleshooting
Safety first: Remove the battery before manipulating joints or connectors.
- Check battery fit: Insert the battery and ensure it clicks firmly. Wiggle it gently; if power cuts in and out, the contacts or latch may be worn.
- Test movement: With the vacuum running (battery installed), gently move the handle and wand through their full range while listening for power loss. Then remove the battery before further work.
- Inspect connectors: Check all plug-in joints (handle-to-body, body-to-tube, tube-to-nozzle) for looseness or visible damage.
- Secure or replace: If a particular joint causes cutouts, the connector or internal wiring in that section likely needs replacement. Often the entire tube or handle assembly is replaced.
- Avoid strain: Until repaired, avoid twisting or bending the vacuum sharply, as this can worsen the break.
