Strong burning smell during operation, sometimes accompanied by smoke from the nozzle area.

Safety first: Turn off and unplug immediately if you smell burning or see smoke.

• Remove bottom cover: Access the brush roll and belt area.
• Clear obstructions: Remove any trapped fabric, cords, or debris from the brush and housing.
• Inspect belt: Check for melted, glazed, or stretched belt. Replace if damaged.
• Check brush bearings: Ensure the brush spins freely. Replace the brush roll if bearings are seized.
• Test after repair: Reassemble and run briefly. If smell persists, discontinue use and inspect the motor for overheating.
