Part 1. Why Does My Vacuum Smell Burnt & How to Fix?

Still thinking, why does my vacuum smell burnt? Then, there is no need to think more as the following is a list of some reasons and how you can fix them.

1. The Electric Motor Is Damaged

The first and foremost reason for “why my vacuum smells burnt” could be the motor failure. Motor failure is a prevalent reason for burning smells, and this is a very serious fault that should be addressed immediately.

To be entirely sure about it is recommended to first check the other accessories like belts, filters, or wands to rule out the causes. The only fix for this issue is getting a professional’s help. Or you can take it to the local vacuum store for motor replacement.

2. The Belt Is Severely Damaged

The second most common reason for the burning smell is the drive belt. If you feel that the vacuum smells like burnt rubber, then there is a high chance that the drive belt is damaged. Sometimes, it also snaps or is significantly damaged beyond repair.

The belts are primarily found in vacuums with rotatory brushes, as their job is to turn the rotatory bar present in the head. The damage can cause overheating of the belt, which gives out an awful smell. No worries, you can replace the belt as these are repairable with the new belt, and you are good to go.

3. The Filters Are Blocked/Clogged

The motor is fine, and the belt looks good, but still, you can't stop wondering, why does my vacuum smell burnt? Well, there is one other thing that you can check. That is the filter screens. The vacuum needs steady airflow to keep It from overheating. But if the filters are clogged with grime and dust blocking the airflow, they can overheat and smell burnt.

However, this can be fixed by cleaning the filters regularly. For that, Check the vacuum manually to determine if the filters are washable. If yes, clean them with cold water and let them dry for at least 24 hours. However, if they are not washable, you may need to replace the filters.

4. Something Is Wrong with The Socket/ Cord

Sometimes, it is not the internal parts, but the problem is external. If you are sure everything is fine but still can’t figure out the burning smell. Then you should check the socket in which you have plugged the vacuum. There could be an issue of heavy or light circuits.

Moreover, you also need to check the cord of the vacuum. If it's too hot, then it means it is melting from the inside. Immediately switch off the vacuum.

For socket issues, you can try plugging in a different socket; otherwise, you might need the help of an electrician.

Part 2. Why Does My Vacuum Smell Bad? Other Reasons

While the above reasons might be the most common ones, there are some other factors that you should consider when you are on the hunt to find out why does my vacuum smells bad.

Vacuum is New

Well, if you have a completely brand-new vacuum, it is common to have a bit of smell. But it should go away after some use. Besides, this smell shouldn't be bad or feel like something is burning. However, if it feels awful, you need to check your vacuum.

There Is Blockage in the Brush

If the rotatory brush is blocked with hairs, furs, and threads, this can be a reason for the awful smell. When it is not cleaned, the friction of the hair causes overheating, which in turn emits a burning smell.

After every use, clean the brush thoroughly for better performance.
