If you are on this page, then you are probably in need of some assistance regarding your burning vacuum belt. Your vacuum belt is the one that drives your carpet cleaning machine and sweeps dirt into the bin. There is a reason why vacuums have belts. They help power motor-driven functions that result in the vacuuming process. So if your vacuum belt keeps burning, then, it’s time to seek help. And this article is your key to solving this issue. Keep reading to know more!


The short answer is yes. Vacuum cleaners can be prone to burnt vacuum belts, especially if you are using one that is not the right size for your home. This is because the belts have to work so hard to keep the machine running smoothly, and this can drive them past their breaking point.

But there are the latest models that have automatic shut-off functions that will turn off the machine if they’re overheating and could potentially cause a fire or damage. However, even with this safety feature in place, it’s still important to check the condition of your vacuum belt regularly so you can catch any issues before they become serious problems.


A burning smell coming from your vacuum is never good. In most cases, it means that there’s a belt or brush roll motor that isn’t working properly. Luckily, there are many reasons behind this and each one can be fixed easily with some troubleshooting.

? Broken drive belt

The drive belt is a small, rubber belt that connects your vacuum cleaner’s motor to the brush roll and agitator. If it is worn or broken, your vacuum will not be able to pull dirt away from your carpet and into its bag or filters. In some cases, if you turn on the vacuum without first checking for damage to this belt, it may burn out in use.

If you cannot find the drive belt yourself, check your owner’s manual for help locating it (some vacuums have multiple belts).

If you find that your drive belt has been damaged or is worn beyond repair (or if you are unsure whether it needs replacing), you can easily replace it yourself with a generic replacement part available at most hardware stores or home improvement centers.

? Tight belt

The first thing to check if your vacuum belt is burning is whether it’s too tight. This can happen when the belts get stretched out and worn down over time, and it can also happen in new bags if you haven’t loosened the tension enough on them. If the belt has become so tight that it can’t spin freely, this will cause friction, which will heat up and burn through all of your other parts, including, potentially, your motor!

? Clogged brush roll

When the brush roll stops spinning, it can be for a number of reasons. One of these is that something may have been trapped in the brush roll itself. To check for this, remove the vacuum’s bottom plate and look at the area where the belt connects to the motor shaft. You should see some empty slots in this area. If you find anything stuck in those spaces (like hair or debris), use tweezers to remove it so your belt will spin freely again!

? Clogged air path

If your vacuum cleaner is experiencing a burning smell, it could be due to a clogged air path. If you’ve ever had your dryer or washing machine break down, then you’ll know what I’m talking about. You may not know what’s wrong with it until you open up the machine and find that there’s an entire load of laundry jammed in the middle of everything else.

The same can happen with vacuum cleaners if the hose has become clogged with pet hair or other debris from around your home. This will restrict airflow through the vacuum and might even cause overheating if it gets bad enough because there isn’t enough fresh air being sucked into the bagless dirt cup or dust bin (depending on how new your model is).

? Overheating vacuum

If the belt is burning, there’s a good chance that your vacuum is overheating. As mentioned, your first step should be to check for clogs in your vacuum bag and hose. If these are fine, the brush roll may be at fault. Remove the brush roll and check it for wear or damage. If it looks worn out or damaged, you’ll need to replace it before putting the machine back together.

If none of these things help fix your problem, then consider checking your air path. If something has become lodged in there (like a sock), this can prevent proper airflow through the machine and cause overheating (which leads to belt burning).


Vacuum belts are a pretty simple piece of equipment, but they can break down unexpectedly. If your vacuum belt is burning, don’t worry! You’ll be able to replace it in no time at all! Here’s what you need to do:

? Turn off the vacuum

First and foremost, turn off the vacuum and unplug it. This is a good thing to do when you get started on any work, whether it’s taking apart your vacuum or replacing the belt. It’s always best to be safe when working with electrical devices!

? Check for obstructions

The next thing to do when you notice a burning smell coming from the vacuum is to check for obstructions. If there are clogs and debris in the vacuum, it will overheat and cause the belt to burn. The first thing that you should do is remove any attachments that are on your vacuum so that they don’t damage anything else.

Next, check inside your vacuum for any large pieces of dirt or other objects that may be preventing airflow through the machine. If there are any large pieces stuck in there, use a bulb syringe (a medical tool used to suck up water) or something similar to remove them from within your machine. After checking for obstructions, it’s time to check out what else might be going wrong with your vacuum cleaner!

? Remove the brush roll

Once you have removed the bottom plate, you will notice a series of bristles attached to a cylinder. This is known as the brush roll.

The brush roll is what causes debris to move while vacuuming and can become clogged with hair or fibers from carpeting. To remove the brush roll from your vacuum, use a screwdriver to pry off its cover. Be careful not to damage any wires or other parts inside it! Once you have done so, look for any clogs or obstructions that may be causing the burning smell. Use tweezers or anything else that works best for you when removing these obstructions and then replace everything in reverse order (with caution).

? Remove debris from the beater bar

If the belt is burning, you will need to remove debris from the beater bar. Use a vacuum brush or attachment to clean the beater bar. A toothbrush can also be used if necessary, but be sure not to scratch it! If you have access to compressed air, use that as well!

? Replace the vacuum belt

To do this, first, turn off and unplug your vacuum cleaner. Then, lift up on the front of the cover until it lifts off of its hinges. You should see some screws holding it in place, so remove them with a screwdriver if needed; then set aside that part of your vacuum cleaner for now so we can get at those belts!

Find where each belt goes on your machine. They’ll all be stretched around some pulleys or gears. Then pull out the old ones (you may want to use pliers). Put in new ones by threading them into place (again, check online for instructions specific to your model) and reattach everything back together again. Now comes perhaps one of our favorite parts: turning on our new-and-improved vacuums!


Vacuum belts stretch and wear out. The belt can cause the vacuum motor to overload, which happens when the brush roller doesn’t turn freely on the motor shaft or burns. If you have a burned belt, it’s time to change it!

1. Make sure to change your vacuum belt every 6 months.

The most important thing you can do to keep your vacuum belt from being burnt is to make sure it gets replaced every 6 months. If you don’t, the belt will wear out and cause the vacuum motor to overload. This will cause the belt to slip on the motor shaft or burn.

2. Check for obstructions in the brush roller.

Check for obstructions or tangles of hair in the brush roller. If you find any, remove them. If you can’t remove them, replace the brush roller. If you can’t find a brush roller, replace the vacuum belt.

3. Check that furniture is not blocking your path of cleaning.

Vacuum cleaner belts are subject to wear and tear. With regular use, they can get worn out over time.

If your vacuum belt is not in good condition, it may burn when you use it for cleaning purposes. This can be very dangerous since the burning of a vacuum belt may lead to serious damage to your house and its occupants.

To prevent this from happening, always make sure that furniture is not blocking your path of cleaning. If there is any obstruction that prevents you from moving freely while vacuuming, then remove it at once so as not to damage your vacuum belt or even worse cause an explosion within your home!

4. Be aware to not be using an extension cord when vacuuming.

The most important thing to keep in mind is that you should not be using an extension cord when vacuuming. You should always use a short cord to plug your vacuum into the wall. Also, make sure that it has a grounded plug and the correct gauge wire for the length of the extension cord you’re using. Lastly, make sure that it is long enough so that it can reach the outlet where you want to plug it in.

5. Do not subject your vacuum cleaner to excessive heat, such as leaving it in direct sunlight.

Do not subject your vacuum cleaner to excessive heat, such as leaving it in direct sunlight. Vacuum cleaners are not meant to be left in direct sunlight and can overheat and catch fire if left in direct sunlight for an extended period of time. In addition, it is important that you store your vacuum cleaners out of reach of children so that they do not get hurt by the moving parts or fall victim to any injuries from falling on top of them.


A burned-up belt is not an uncommon problem in vacuum cleaners. If you are lucky, the burning smell will be accompanied by the smell of melting plastic and rubber. If you notice either of these, stop using your cleaner right away. You can try replacing parts or getting professional help to repair it. With straightforward maintenance, though, you shouldn’t need a professional or a new vacuum.
