How to Fix / Troubleshooting
Safety first: Turn OFF the vacuum and remove the battery. Do not run the motor if it smells burnt or is excessively noisy.
- Step 1 – Isolate noise source: Remove the floor nozzle and tube, then run the handheld unit only. If the noise remains, it is likely the main motor.
- Step 2 – Check for foreign objects: Inspect the air inlet near the motor for debris that may have reached the fan. Remove any visible objects.
- Step 3 – Short test: Run the motor briefly. If the noise is metallic, grinding, or accompanied by burning smell, stop using the vacuum.
- Step 4 – Replace motor: The main suction motor assembly with bearings and fan should be replaced as a unit. This is typically a professional repair.
