Why my vacuum cleaner sounds so loud is not only yours but the most nagging query of the homeowners who like to keep their nest squeaky clean without having to deal with high pitched noise of the vacuum.
A glitch-free, silent and powerful vacuum cleaner is super-fun, and relaxing while cleaning home with a noisy and interrupting one is the ultimate mood spoiler, you will agree with it hands-down.
Wondering what makes your reliable home cleaning appliance sounds loud and frustrating to work with?
Well, there can be many reasons like airflow blockage or wrong height adjustment, here we are listing some possible causes below behind your squealing vacuum cleaner.
The Filters Are Clogged
If you want your vacuum to work efficiently without any noise, keep the filters clean.
The filters of a vacuum tend to be clogged with dirt and debris that directly affects the suction. When the suction doesn’t work properly, it struggles to suck the mess in.
This can be one prime cause behind your vacuum making a loud noise.
Some vacuum cleaners have two filters – one behind the vacuum bag and a HEPA filter at the back that releases hot and clean air. Check both the filters.
Refer to your user manual to locate the filters in your vacuum cleaner, detach it from your vacuum and clean it under the tap water (if it is washable).
If your filters are not washable, you will need to replace them with new ones.
To bring your vacuum cleaner back to its normal cleaning mode, clean the filters every week or replace them every 3 months or as your user manual suggests.
Your vacuum needs some upkeeping from time to time to function silently and efficiently.
Something Is Stuck In The Hose
Another reason your vacuum is screaming is because something might be stuck in the hose like debris, your toddler’s or pet’s toy pieces.
As the vacuum sucks the dirt with powerful suction through the hose, any obstruction or blockage in the way will make the vacuum cleaner squeal for applying extra effort to do the job.
To fix this, you must remove the cause of blockage by disassembling your vacuum cleaner carefully.
Detach the hose from the vacuum and use a long wooden stick, knitting needles, or metal hanger to clear the blockage and bring your vacuum back to its normal silent mode.
The Vacuum Bag Is Full
You must also check the vacuum bag. If it’s full it needs to be emptied or replaced.
When your vacuum bag is full, the sucked-in dirt starts blocking the nozzle and the hose and makes that annoying high-pitched noise.
To get rid of this whining, empty the vacuum bag and do the needful to clear the path of the suction flow down the hose to the bag.
A full vacuum bag is another major reason behind your squealing vacuum.
So, keep an eye on the vacuum bag indicator and empty/replace the bag if it indicates that the bag is full.
This will not only keep your vacuum in good working condition but will also eliminate any foul smell coming from your vacuum when you clean.
Fan Blades Are Unbalanced Or Broken
If your vacuum sounds like a jet engine it might be the fan blades are unbalanced because it has accumulated dirt over time during the process of regular cleaning.
If that’s the case, clean the fan with an old toothbrush to shrug off the dirt, and then wipe the blades with a soft microfiber cloth.
Let the blades dry completely before you assemble the whole setup back. This should fix your problem.
Another reason could be that the fan blades are broken.
If you have vacuumed the heavily soiled area of your home recently then the fan blades might have caught small pieces of debris and bent or broken your fan blades.
Check your blades to see if it’s bent or broken around the edges. If it is you will need to replace the fan to ensure your vacuum cleaner performs smoothly without any annoying noise.
Yet another reason your vacuum could be making high-pitched grinding noise is because some debris is stuck between the fan blades and the motor.
Rotate the fan with your hand to see if it’s swift and smooth. If you hear a grinding noise, disassemble the fan to deep clean it.
The Brush Bearing Is Broken
Another cause of your loud vacuum cleaner can be a broken brush bearing for sucking in hard objects.
When you clean up hard objects with a vacuum cleaner, which are not actually meant for vacuum cleaning, they are likely to cause damage to the brush bearing over time making the appliance vibrate and squeal.
Besides this, the brush roller often gets clogged with strings of hair and debris causing airflow obstruction in the nozzle, leading to high-pitched noise.
If that’s the case, call the professional who will help you fix the broken brush bearing and get rid of annoying whining.
The Surface Of The Floor Matters
Have you noticed your vacuum is making different noises while cleaning on different floors?
This is because of the imperfect height adjustment and settings you are ignoring while vacuuming the floors.
If you are vacuum cleaning flat or bare surfaces on a high setting, it will generate a high-pitched noise, and the cleaning will not be satisfactory.
To clean flat surfaces, choose low settings, for carpeted surfaces switch to medium settings, and select high settings for high pile carpet surfaces to ensure your vacuum doesn’t struggle to perform making annoying noise.
Keep changing the head settings or brush level to suit your purpose while vacuum cleaning different floors.
Frequently Asked Questions
Why is my vacuum cleaner making high-pitched noise?
There can be any of the several reasons we mentioned above behind your loud vacuum cleaner.
Your vacuum cleaner is making a high-pitched noise because of the airflow obstruction that happens due to clogged filters, hose, or fan. The vacuum also makes a loud noise if the brush bearing is broken, fan blades are bent around the edges, or debris is stuck between the fan and the motor.
If you vacuum clean your home quite often, clean the appliance weekly, and replace the filters timely (every 3 months) to ensure your vacuum delivers silent and efficient performance.
Also, while cleaning different floors, keep in mind the settings and height adjustment which can otherwise lead to an annoying cleaning experience.
What should be the ideal noise level of a vacuum cleaner?
Normal conversation happens at 60 dB and we whisper softly at 30 dB.
It’s normal for a vacuum cleaner to release some sound in action but should never be loud or whining.
A loud vacuum is a clear indication of malfunctioning and needs an urgent fix to get back to normal mode.
For a normal functioning vacuum cleaner, the sound level should be between 61 – 70 dB, whereas a problematic vacuum releases 70 – 75 dB of annoying sound raising an alarm for an immediate check-up and necessary replacements.
Exposing yourself to a noise level above 70 dB for a long time can cause hearing loss.
So, if your vacuum cleaner is yelling take it to a repair shop to fix the possible reasons and get the vacuum back to its normal humming.
It’s okay for a vacuum cleaner to seek your attention with loud high-pitched noise to call for immediate cleaning and replacement so you can maintain a healthy home environment.
When a vacuum cleaner gets extremely dirty with debris in the hose and clogged filters, it does more harm to your home by releasing the foul smell, dirt, and germs indoors and of course the noise.
So, keep the vacuum cleaner clean and replace the filters as needed to prevent it from making a loud noise.
