If your vacuum cleaner smells like fire, this is a sign that something has gone mechanically wrong. This can be dangerous, so it’s important not to simply ignore it. In this article we explain exactly what to do if you smell a burning smell while using your vacuum cleaner.
If you are unsure of performing these steps yourself, seek the help of a professional, book your vacuum cleaner for maintenance or contact your vacuum cleaner manufacturer for advice.
Mechanical problems are just one thing that can cause a vacuum cleaner to smell. If the odor does not smell like burning, it may be a problem that can be resolved with a good cleaning. Our article explores why your vacuum cleaner stinks and what you can do about it has a lot of specific advice.
The first and most important step is to turn off the vacuum cleaner and unplug it from the wall socket. 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 obstructed airflow. So inspect the vacuum cleaner’s hose, brush roll and filter for blockages such as dust, hair or dirt. If necessary, use a flashlight to look in all accessible areas. Clogs can cause the engine to overheat as it struggles to draw in air, leading to a burning smell.
3. Inspect the belt
A burning smell can 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 cleaner’s brush roll and examine the belt for signs of wear, stretching, or melting. If it looks damaged, replace it.
4. Examine the engine
If there is no blockage and the belt is intact, the problem may be with the engine itself. An engine can overheat due to dust build-up, electrical problems, or simply because it is reaching the end of its lifespan. In this case, stop using the vacuum cleaner until you have it serviced by a professional.
5. Call for help
If you are unsure where the odor is coming from, 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 all that doesn’t work and your vacuum cleaner is on the older side, it might be time to invest in a new model. Our guides to the best vacuum cleaners or the best cordless vacuum cleaners can help specifically.
