Possible Causes
Worn carbon brushes in motor, Contaminated commutator, Overloaded motor due to blockages, Internal motor insulation breakdown
How to Fix / Troubleshooting
Safety first: Turn off the vacuum immediately, remove the battery, and do not continue using it.
Assessment:
- Check for blockages and clean filters to ensure the motor is not overloaded.
- If the smell persists even with clear airflow, the motor brushes or commutator are likely worn.
- On most Russell Hobbs cordless vacuums, the motor is supplied as a sealed unit; brush replacement is not user-serviceable.
- Arrange for motor replacement or consider replacing the main body assembly.
Warning: Continued use with heavy arcing can cause fire or complete motor failure.
