Possible Causes

Worn motor bearings, Damaged motor fan, Cracked cyclone or bin causing whistling air leak, Loose seals around motor housing

How to Fix / Troubleshooting

Safety first: Remove the battery before inspecting internal parts. Do not run the motor with covers removed.

Steps to try:

  • Check for air leaks: Run the vacuum briefly and listen around the bin and joints for whistling. Reseat the bin and ensure all latches are fully engaged.
  • Inspect bin and cyclone: Look for cracks or gaps in the plastic that could cause high‑pitched noise.
  • Assess motor noise: If the screech comes from the motor area and persists regardless of attachments, the motor bearings are likely worn.
  • Replace assembly: Motor bearing replacement is not typically user‑serviceable on Gtech cordless vacuums. Replace the main body/motor assembly.
