Unit emits a burning smell during operation, sometimes accompanied by reduced performance.

Safety first: Switch off, unplug immediately, and allow the unit to cool. Do not continue to run it with a burning smell.

• 1. Check for blockages: Inspect hose, nozzle, and filters for clogs that could overwork the motor.
• 2. Inspect brush and belt: Remove the brush cover and check the belt for glazing, cracks, or burning. Replace the belt if damaged. Ensure the brush spins freely.
• 3. Smell source: With the cover off (and unit unplugged), smell near the motor and belt area to identify the source. A rubber smell suggests belt; an electrical smell suggests motor.
• 4. Motor evaluation: If the smell is electrical and persistent, the suction motor may be failing and should be replaced by a technician.
