How to Fix / Troubleshooting
Safety first: Immediately turn off the vacuum, remove the battery, and allow the unit to cool. Do not continue using it until the cause is identified.
- 1. Inspect brush roll: Remove the motorized nozzle and check for hair or debris tightly wrapped around the brush. Clear all obstructions and ensure the brush spins freely.
- 2. Check for melted plastic or belt smell: Look for discoloration or melted areas around the brush ends and belt (if visible). Replace the brush roll assembly if damaged.
- 3. Clean filters and vents: Ensure all filters are clean and vents are unobstructed to prevent motor overheating.
- 4. Test briefly: After cooling and cleaning, run the vacuum for 30–60 seconds and monitor for smell. Stop immediately if the odor returns.
- 5. Persistent burning smell: Indicates internal motor damage or electrical arcing. Discontinue use and have the motor and PCB inspected and replaced by a technician.
