Burning smell (rubber or electrical) while using the carpet cleaner.

Safety: Turn off and unplug the unit immediately if you smell burning.

• 1. Check brush for jams: Remove the nozzle and inspect the brush roll for hair and debris. Clear thoroughly.
• 2. Inspect belt: Remove the brush drive belt. If it is melted, stretched, or has a burnt smell, replace it.
• 3. Look for scorch marks: Inspect the belt area and motor housing for signs of overheating or melted plastic. Persistent overheating may indicate a failing brush motor or suction motor.
• 4. Electrical smell: If the smell is sharp and electrical, do not reuse the machine until inspected. Check for burnt wiring or a scorched main control board. Replace damaged components.
• 5. Test carefully: After repairs, run the unit briefly and monitor for any recurring smell.
