How to Fix / Troubleshooting
Safety first: Turn OFF the vacuum, remove the battery pack, and allow the motor to cool before inspection.
- Step 1 – Isolate the source: Run the vacuum briefly without the floorhead (wand only) and then as a handheld without the wand. If the noise persists in all configurations, it is likely from the main motor.
- Step 2 – Check for loose parts: Inspect the bin and cyclone for loose plastic pieces or foreign objects that could be contacting the fan.
- Step 3 – Internal inspection (advanced): If comfortable, open the motor housing to inspect the fan area for debris. Remove any foreign objects carefully.
- Step 4 – Motor replacement: Persistent screeching usually indicates failing bearings. Replace the main suction motor assembly.
Warning: Do not continue using the vacuum with a screeching motor; it can seize and overheat, posing a fire risk.
