Cordless vacuum emits a burning smell during or after use.

Safety first: Immediately turn OFF the vacuum, remove the battery, and allow the unit to cool. Do not continue using it until the cause is found.

• Inspect brush head: Remove the head and check for hair or debris tightly wrapped around the brush roll. Clear thoroughly.
• Check belt (if present): If you smell burnt rubber, inspect the belt for melting or glazing. Replace if damaged.
• Clean filters and airways: Ensure all filters are clean and the air path is unobstructed to prevent motor overheating.
• Smell motor area: After cooling, smell near the motor housing. A persistent burnt electrical odor suggests internal motor damage.
• Do not ignore: Continued use with a burning smell can lead to failure or fire risk. If the smell returns after cleaning, have the motor or brush head professionally inspected and replaced if necessary.
