Vacuum produces a burning smell or hot plastic odour during use

Safety first: Immediately switch OFF the vacuum, remove the battery or disconnect from charger, and allow it to cool. Do not continue using it until the cause is found.

• Step 1 – Inspect brush roll: Remove the motorised nozzle and open the brush housing. Clear all hair and debris from the brush roll and end caps. Check for melted plastic or burn marks.
• Step 2 – Check brush motor area: Smell near the nozzle. If the odour is strongest there, the brush motor may be overheating. Replace the nozzle if there are signs of melting or burning.
• Step 3 – Check main unit: If the smell comes from the handheld unit, the main motor may be overheating due to blocked filters or internal damage. Clean filters and vents thoroughly.
• Step 4 – Test briefly: After cleaning and cooling, run the vacuum for a short period while monitoring for smell. If the burning odour returns quickly, stop use.
• Step 5 – Professional service: Persistent burning smell indicates a failing motor or electrical fault. Arrange inspection and motor/nozzle replacement through an AEG service center.
