If your vacuum cleaner smells burning, it’s a sign that something mechanical has failed. This can be dangerous, so it is important not to ignore it. In this article we will explain exactly what you should do if you smell burning when using your vacuum cleaner.
If you don’t feel confident performing these steps yourself, you should seek the help of a professional, book your vacuum cleaner for a service, or contact the manufacturer of your vacuum cleaner for advice.
The first and most important step is to turn off the vacuum cleaner and unplug it from the outlet. This prevents further damage to the machine and eliminates the risk of electrical fire.
2. Check for blockages
A common cause of a burning smell is airflow obstruction. Therefore, inspect the vacuum hose, brush roll, and filter for blockages such as dust, hair, or debris. Use a flashlight if necessary to look at all accessible areas. Clogs can cause the engine to overheat as it struggles to draw in air, causing a burning smell.
3. Inspect the belt
A burning smell may occur if your vacuum cleaner’s belt is worn, misaligned, or broken. That can cause it to rub against other components or slip while the engine is still running. Access the vacuum’s brush roll and examine the belt for signs of wear, stretching, or melting. If it appears damaged, replace it.
4. Examine the engine.
If there is no obstruction and the belt is intact, the problem could be with the motor itself. A motor can overheat due to dust buildup, electrical problems, or simply because it is reaching the end of its useful life. In which case, stop using the vacuum until it is checked by a professional.
5. Ask for help
If you are unsure of the source of the odor or if the vacuum continues to emit a burning smell after performing basic checks, it is best to contact a technician for repair.
6. Buy a new vacuum cleaner
If none of that works and your vacuum cleaner is older, it might be time to invest in a new model. Our guides on the best vacuum cleaners or the best cordless vacuum cleaners specifically can help.
