Vacuums are a great way to keep your home tidy, but even with all the advances in modern technology, a few common vacuum issues can still arise from time to time.
My expert vacuum team researched the most common vacuum issues and how to avoid them.
But that's not all...
As experts in our field, we discuss the following in this article:
Let's have a closer look at what some of these problems are and how you can go about tackling them…
While you may be cleaning, an odd smell isn’t always part of the package.
After extensive use, it’s only natural for your vacuum cleaner to start experiencing use-related difficulties.
While a weird smell isn’t exactly a difficulty, it can indicate a problem.
There’s a good chance that the dirt fan is dirty if your vacuum cleaner has been giving off an odd smell while running.
First, to replace this part, unplug the machine and remove any attachments where applicable, like brushes or extension tubes.
Then locate the screws that hold on the bottom cover to open up access to the motor.
Locate the dirt fan inside (it’ll be visible in front of you) and gently pull it out of its position.
If cleaning up leaves more of a mess behind than anything else, you have a problem.
Here’s why.
If you notice debris collecting around one side of your vacuum bag rather than evenly distributed inside it, then this may be why debris seems stuck in certain areas when vacuuming various floor surfaces.
Detach from front to back (while still keeping upright) and ensure there are no tears or holes on either end before reattaching back together again with ease.
A vacuum that can’t suck up dirt and debris is pretty useless.
Here’s how to ensure that you’ve got the right amount of suction:
Most of the time, a vacuum's inability to pick up dirt is caused by a few simple problems that are easy to fix.
A clogged air filter or blockage might be to blame for a loss of suction; most people don't think of a full vacuum bag as a cause of insufficient suction power, but it’s one of the main reasons for this.
As a result, be sure to check for any obstructions in any of these areas: the floor head, neck, hose, brush, and blower wheel.
Alternatively
The dust cup must fit snugly to provide an effective suction force.
If it's loose or broken, the machine won't be able to create enough suction force.
My team advises that you remove any attachments such as brushes or extension tubes, then check for blockages by looking inside a hose with a flashlight; you should be able to see if there are any clogs from this vantage point.
If not, try running water through it while unplugged (be careful not to get too wet).
Additionally
Check that there are no tears or holes on either end of the bag before reattaching it again with ease.
Detach from front to back (while still keeping it upright) to clean out debris trapped inside before putting it back together again.
Vacuums aren’t exactly the world’s quietest appliances, but every so often they may let out a cry for help.
Here’s how to silence the noise:
Your vacuum might occasionally start making louder and more excessive noises.
There are a number of potential causes for this issue, including clogs, leaks, and inadequate insulation.
If there’s a blockage, the vacuum may have to exert unnecessary force to get enough suction power.
Don't forget
If the vacuum brush makes a noise, there’s likely a clog or a damaged brush roller.
Most vacuum noises are caused by problems with the belts; when the belts aren't fastened properly, they make a very strange and loud sound as soon as the suction starts.
If your vacuum cleaner makes a high-pitched noise or smells like burning rubber, then it’s likely that the belt is broken, which will require you to replace this part for the machine to function properly.
We’ve all been there…
Vacuuming up a storm when suddenly things get heated - literally.
Here’s what to do:
A vacuum cleaner frequently overheats, especially after continuously vacuuming for extended periods.
However, the cleaner occasionally overheats to the point where hot air and smoke are released, usually indicating a malfunction in the electrical system, particularly the motor.
If your vacuum cleaner has been making a high-pitched noise or smells like burning rubber, then it’s likely the motor is malfunctioning.
If it smells like something’s burning when you clean and it’s not that scented candle, then there’s a problem.
Here’s the potential issue:
Another frequent problem experienced by vacuum cleaner users is the burning smell, which usually means a damaged motor belt is to blame.
The rubber belt burning because of elasticity loss may also cause the burning odor.
Overall, the belt must most likely be replaced because it’s worn out.
The first step in troubleshooting the issue is to unplug the vacuum and inspect it for any obvious signs of damage or overheating, such as a melted or frayed cord or a hot motor.
It's important to check the dustbin or bag and empty it or replace it if it's overfilled.
If the burning smell persists, it's best to take the vacuum to a professional for inspection and repair, as it could be a more serious issue with the motor or other components.
Easily one of the biggest issues you could face: a dead vacuum.
Let’s fix this.
If your vacuum won’t switch on, check to see that it’s properly plugged into the switchboard.
The electronic control board (PCB) may have burned out if the appliance is properly plugged in, and if that’s the case, the PCB has to be changed.1
It's possible that the drive motor is broken or that the thermal fuse isn't working right, meaning that the overheated motor has burned out and stopped power from getting to the motor.
Check that the on/off switch is in position to turn your vacuum cleaner off and on.
You should double-check that the batteries are charged and securely attached to the robot cleaner, and if they’re not, recharge the device.
If the vacuum won't switch on even after you've double-checked the power supply and ensured it's connected properly, it might mean the vacuum needs new components or a complete replacement.
You might try unplugging the vacuum cleaner from the circuit board and manually twisting the motor shaft to look for any obstructions.
This part of the vacuum is responsible for cleaning things up.
Here’s what to do if it isn’t:
It makes sense that your vacuum head would become slightly clogged after hours of collecting hair and lint from your floor.
If the floor head has a brush roller, you can usually remove it for cleaning.
Cutting any knotted hair or threads with scissors, a thread ripper, or a small knife will remove them and clear out the cleaning head.
Check that they aren’t bent, broken, or otherwise damaged, which can cause a vacuum cleaner’s brush rollers to wear unevenly over time (which will interfere with how well your machine picks up dirt).
If your vacuum cleaner isn't overheating but is smelly, it may be the belt.
Here’s how you can check:
When trapped solid dirt particles like lint, string, or hair are involved, a vacuum belt may frequently break.
In general, problems with the brush roll assembly, especially with the bearings, can affect the vacuum cleaner belt directly.
Any kind of obstruction in these areas puts the belt under too much stress, which can lead to damage and, if not fixed, a broken vacuum.
The brush is responsible for lifting dirt and making it easier to suck up.
Without it, you’re more than likely wasting your time.
Let’s take a better look at this:
Most of the time, the brush won't spin because of problems with the vacuum’s belts; the cleaning brush won't spin if any of these belts are too stretched, damaged, or out of alignment.
A blocked brush roll may also be the source of this kind of issue.
In this situation, the brush roll needs to be removed and thoroughly cleaned before being replaced.
Keep in mind
Pay close attention to the brush roll assembly and bearings to ensure no outside objects are stuck in them.
Replace the assembly if any cracks or other damage are present.
The beater bar may need to be replaced if it becomes too worn out with regular use.
To replace this part, first unplug the machine and remove any attachments where applicable, like brushes or extension tubes.
Then locate the screws that hold on the bottom cover to open up access to the motor; you’ll find the belt right in front of you when looking at these devices.
Remove any debris caught underneath it before replacing the old piece with a new one.
If the motor seems to be totally dead, this needs further investigation.
Here’s what you can do:
If your vacuum seems to have died, there might be an issue with the main power connector.
Check the primary fuse on the plug to make sure your vacuum is getting power before looking at the appliance itself.
Additional possibilities are that the appliance's electronic control board (PCB) has burned out or that a thermal fuse has blown.
If your vacuum cleaner isn’t turning on, there are a few troubleshooting steps you can take.
The first step is to ensure that it's properly plugged in and that the outlet is working. If it's still not turning on, check the vacuum's power switch and make sure it's in the "on" position.
Inspect the cord for any visible damage or fraying, as a damaged cord can cause the vacuum to stop working.
If none of these steps work, it's best to take the vacuum to a professional for inspection and repair, as there could be a more serious issue with the motor or other components.
It can’t always be smooth sailing when it comes to cleaning, but there are things you can do to try and ensure that it’s a possibility.
Here’s how:
A vacuum that is hard to push is usually the result of dirt buildup on the bottom plate.
In more serious cases, an incorrectly aligned drive belt may be the cause of this, and replacement may be necessary.
The belt will be visible directly in front of you when looking at these devices, so just carefully pull it away from its pulley wheel after removing any debris caught underneath it.
Also
Ensure the handle doesn’t have dust built up along its base where it connects to the cleaner.
If it does, this will likely cause your vacuum to not slide as easily along floors and carpets while vacuuming, which can be a problem for any user.
So you’ve been vacuuming up a storm, and suddenly the hose isn’t sucking up the debris.
What do you do?
This is normal, given that most people prefer to use their vacuums to remove large pieces of trash and debris from their floors.
This is more of a hassle than anything else, and sometimes clearing it out calls for inventiveness.
A blockage in a hose or pipe can cause loss of suction and make a strange sound like growling, whining, or humming when running due to air pressure imbalances inside the appliance.
If there are any attachments with removable parts, such as extension tubes or brushes, they should be checked for blockages or tangles.
A pair of pliers can be used to remove the obstruction, but my research shows that many people have found it more convenient to use a metal hanger as a snake to push through the obstruction.
If moving around the room requires strategic cord placement, it may be time to take a look under the hood.
Here’s why:
Since the vacuum won't turn off until the cord is pulled in a specific way, this issue is easy to spot.
It's crucial to quickly unplug and turn off your vacuum if this happens to you, since it poses a fire risk.
As always, the best course of action is to have a professional fix it, but if you have some basic electrical understanding and can see the broken part of the cord, you might be able to DIY it.
Check the cord for any signs of damage like cuts, tears, or burns that may have occurred while vacuuming, and wrap it in a figure-eight shape to make sure there are no tugs on the wire causing an electrocution hazard.
If you notice corrosion where the plug enters the machine, then this is likely your problem.
You’ll need to replace this part because it’ll lead to electric shocks when using your vacuum cleaner, which can be very dangerous.
If your vacuum is giving up on cleaning before you do, you need to investigate the issue.
Let’s look at why this happens:
This happens because the vacuum is overheating; it typically has a safety feature that keeps it from getting too hot, so once it reaches a particular temperature, it’ll immediately turn off.
When the user decides to clean up the rest of the building debris, the tiny particles may get into the motor compartment and cause it to overheat.
If this doesn’t seem like the reason for your vacuum issue, you might consider switching your vacuum's suction setting because your carpet can obstruct the intake valve.
The first step is to check the power cord and ensure that it's not loose or damaged.
If the cord looks fine, inspect the filters and clean or replace them as needed, as clogged filters can cause the vacuum to overheat and shut off.
Lastly, make sure that the dustbin or bag isn’t overfilled, as this can also cause the vacuum to turn off.
If all else fails…
If the problem persists, it's best to take the vacuum to a professional for inspection and repair.
When your vacuum starts channeling its inner snail and leaving a trail, you’ll want to determine the issue.
Let’s get started:
This could be a hint that the roller brush needs to be washed because it’s dirty or that there are clumps of dirt in the bag or container.
The vacuum has a harder time consistently picking up dirt off the floor because the roller brush gathers hair and other fibers, which ultimately end up winding around the brush.
This may also have to do with your belt, which can impede the rotation of your roller brush.
The roller brush may need replacing if it becomes worn over time with use or starts making strange noises when being used for cleaning carpets.
This piece should slide right out once you’ve removed any other parts, such as hoses and extensions.
If your vacuum keeps losing power or, worse, overheating, I may have found the culprit.

To keep your vacuum running efficiently, you should clean its filters frequently.
Refer to your handbook for the initial clean if you haven't done it previously, and then set a reminder to wash the filters once a month or so.
It’s important to note
Before you place them back in the vacuum cleaner, let them dry completely.
HEPA filters2 are the only exception to this rule because they often can’t be washed, but always consult your manual for proper guidance.
Remove the filter and inspect it for any visible signs of dirt or debris.
If it's dirty, clean the filter according to the manufacturer's instructions or replace it if it's not washable.
Make sure to clean the dustbin or replace the bag, as a clogged filter can cause the vacuum to overheat and reduce suction power.
Avoiding common vacuum faults can be achieved by following my 5 easy tips.
My knowledgeable vacuum team has tried and tested the best methods for maintaining your vacuum so that I can present you with these handy top tips.
Let’s look at these tips:
It's a good idea to empty or clean vacuum bags often, and some sealed bags should be thrown away and not used again.
The vacuum motor may frequently overheat if these bags are reused while the machine is in use, and, similarly, vacuum filters that have been clogged with dust need to be replaced.
This guarantees your machine's optimal cleaning capabilities.
The machine belts often become overstretched as a result of the strain they endure, and if put under too much stress, they could break.
To ensure your cleaner performs at its best, it should be frequently replaced.
Flat drive belts should be changed twice annually, although cogged belts are usually only changed when they’re damaged.
Inadequate brush roll maintenance is frequently to blame for the majority of vacuum cleaner problems.
Obstructive objects like hair, fabric, or threads often get caught in the brush roll, and because of this, they can't turn as freely and end up causing more friction when in use.
These obstructions frequently lead to increased pressure on the belt, so it’s important to make sure that the brush roll system and bearings aren’t blocked in any way.
Any external object that becomes stuck inside the vacuum cleaner's internal hose or exterior hose might negatively impact how well the equipment works.
This puts the drive motor under more stress and may result in issues like overheating.
Overstretching the vacuum flex while using it is a common problem.
This is especially important if your vacuum cleaner has a flex cord that automatically winds back up on itself.
You should trust ByPurify because I dedicate my time, effort, and resources to researching vacuums and their common issues.
I put together a complete guide to the most common vacuum problems and how to fix them, so you don't have to spend hours looking for simple solutions to your frustrating vacuum problems.
Everything you need is right here, neatly compiled in one article.
A burning smell is likely caused by the motor overheating and should be looked at immediately for your safety.
If you can’t find any other machine issues, it may require an electrician to replace this part as soon as possible.
Your vacuum cleaner suddenly stopped working because it likely lacked power.
Ensure that there’s power in the outlet you’re using and that there are no blockages in your vacuum hose or filters.
You would know your vacuum motor is burned out by the strong, burning odor coming from your vacuum.
You know your vacuum belt is bad when it’s not picking up debris as it always has and your vacuum is getting unusually noisy.
Yes, a vacuum can work without a belt, but it won’t work well.
The suction function will still work on your vacuum; however, even though it works on bare floors without a belt, it might not work on carpeting at all.
When your vacuum brush stops spinning, you should remove it, put the brush roll on its head, and spin it to check it; it should spin easily.
If it doesn’t spin several times with a single flick, you’ll need to change the brush roll.
Additionally, check that the belt is aligned and working.
You can take a broken vacuum to a recycling center, scrap yard, or electronic store, or sell it for parts.
Your vacuum motor is sparking because the motor might be old and worn out.
Beware of this and call a repairman if necessary.
Excessive sparking at the brushes could be caused by worn brushes that reduce spring pressure, commutator segments that are too rough, or carbon dust between the commutator segments.
You can tell a vacuum is broken by the sounds it makes, and it might also give off a burning smell.
Yes, it’s worth repairing a vacuum.
When it comes to vacuums, there are different levels of quality and value.
If the device was expensive to purchase, repairs are probably worthwhile, but I advise that you not spend more than half of the original cost of your vacuum on any repairs.
I think you’ll agree with me when I say that it’s REALLY hard to choose the best ABC with all the choices available.
After hundreds of hours of testing & reviewing, I have strong opinions about what makes the best ABC.
I highlight the pros, cons & features of the ABC.
Poor suction power, excessive noise, burning odor, the vacuum not turning on, and overheating are the most frequent issues with vacuums.
Cleaning or changing a few elements of the unit can solve these problems, and if the issue seems bigger than what you might be able to handle, I suggest always consulting a specialist or repairman.
