Why Does My Vacuum Make Loud Noise And How To Fix This?

Generally, Vacuum cleaners make noise when its loaded with dirt. They can also become loud if any component, such as a fan or its blade, is loosely attached or damaged. You can check and clean the filter if it is loaded with dirt to eliminate any extra noises.

Is the loud noise your vacuum cleaner makes upsetting you?

It is unusual for a normal and fine vacuum cleaner to make unreasonably loud and irritating noise. Your vacuum mechanical house helper may be having a problem.

Also, check the vacuum hose and clear it of any clogging if present at all.

In this post, I will discuss a few factors that may contribute to the increased noise level of your vacuum cleaner.

Why is My Vacuum Making a High Pitched Noise?

Why is My Vacuum Making a High Pitched Noise

The vacuum cleaners makes some noise, which we all know, but what’s the reason if the noise has become louder? This can happen for a variety of reasons.

You can identify the actual cause of the noise in your vacuum cleaner by observing the kind of sound produced. 

For example, when there’s a blockage in the hosepipe, the vacuum makes a hissing sound, and when something is stuck in the motor, the machine starts rumbling.

First, let’s talk about the motor, as it is a major factor in the machine’s noise production. The motor in your cleaner may have run out of lubrication or been experiencing some technical issue, which would explain why it produces the high-frequency noise. 

However, this issue seldom affects new devices and mostly affects those that are rather old.

If the vacuum cleaner makes a rumbling noise, something is probably stuck somewhere in the vacuum.

In such circumstances, fixing the issue becomes really easy as you have to focus on the scratchy voice and remove the stuck object from where the noise is coming. 

Reasons Why a Vacuum Can Become Really Loud

A certain amount of noise will always be produced by a vacuum cleaner. You cannot escape that. However, something may be wrong if you discover that your vacuum cleaner is much noisier than usual. 

The following are some typical explanations for why your vacuum cleaner could be noisier than it used to be:

Dirty Filters

Your vacuum cleaner may become significantly louder if the filter is meshed with dirt or clogged. Checking and updating your filter will allow you to determine if this is the issue. If you have not yet changed the filter in your vacuum, the issue is likely the same. 

You can fix the noise easily since replacement filters are inexpensive to purchase, and you can fit them into the unit or you can clean the filters.

Vacuum Hose is Clogged

Your vacuum cleaner may be making a loud noise because of the clogged vacuum hose that connects the main unit to the suction brush. Large objects like stones and coins occasionally clog the pipe by being sucked into the pipe.

The airflow becomes obstructed as a result. In such situations, the engine must work harder to move the air through the apparatus. When brushed with the clogged object, the air generates a grating noise.

To fix this problem, separate the vacuum tube from both ends and find something sharp enough to run through the hose’s entire length. 

Clean it with a metal wire or a narrow plastic handle; this way, you can lower the noise generated by a clogged vacuum cleaner.

Broken Brush Bearing on Vacuum

A motor runs vacuums, and an electric motor’s bearings may deteriorate unevenly and scrape against the bearing rings and one another if there isn’t enough lubricant on them. This friction between the bearings might create a grinding noise.

In severe circumstances, faulty bearings may heat up to the point where the plastic housing melts. The thermal cut-off frequently misses this heat until it is too late to stop serious harm.

Because of how dangerous this type of grinding is, you should not use it until the issue has been fixed.

Vacuum Has Broken Fan

The vacuum fan is to blame if you have one of the vacuums with its fan on the outside. The fan near the engine frequently becomes loose in these vacuums due to consistent use.

The loose fan vibrates along with the motion of its blade, becoming responsible for generating the unnecessary loud noise.

Check to see if the fan is loosened or if any blades are damaged. Replace the fan with a new one if the blades are broken, or securely screw it to the motor’s rear if it is loosened to fix the noise.

How To Get Your Vacuum Cleaner Quieter Again?

Looking for tips on how to make your vacuum quieter again? Here they are:

  • Creating suction requires the engine to operate harder and louder, especially if the filters are dirty. Therefore, cleaning your filters is beneficial for lowering the vacuum noise.
  • Typically, vacuum cleaners include one or two filters; one is located close to the debris bag, and thus, the other one may be a HEPA filter. You can’t clean HEPA filters, so replace them if they are dirty.

Like clogged filters, a little object stuck within the vacuum will reduce the suction power and increase noise. So, look inside your vacuum for any small particles stuck within it and use a pointed object or a needle to remove them.

How To Fix a Loud Noise in a Vacuum Cleaner Motor?

How To Fix a Loud Noise in a Vacuum Cleaner Motor

Here are the steps to fix the loud noise in a vacuum cleaner motor:

Step 1:

You must first determine where the sound is coming from. You can do this by paying close attention to the vacuum cleaner’s noises to determine where the noise is coming.

Step 2:

Once you’ve roughly pinpointed the noise’s source, disconnect the cable cord from the power source to start addressing the issue.

Step 3:

A common reason the vacuum cleaner is noisier is its dust bag or dirt cups becoming full.

Check whether your issue is resolved by emptying and cleaning the dust bag or cup. If it is, then well and good; otherwise, you proceed to the next.

Step 4:

Dirty Filters frequently contribute to higher noise since the vacuum attempts to suction air containing more dust and debris.

The engine is consequently forced to work much harder than usual, which results in a louder noise. Your vacuum will run more quietly if you clean your filters regularly.

Step 5:

Any vacuum component, such as the hose, filter, attachments, dirt canister, or dust container, may become clogged with dirt or other particles and generate loud noises.

Eliminate any particles or object that is blocking the air channel. The noise can also be because of jammed bearings.

A stuck brush can be treated with some lubrication or repair.

Step 6:

An often-overlooked reason is the vacuum cleaner fan. It might have a damaged blade or be loosely attached to the unit, creating a loud noise.

Other broken components, such as the vacuum cleaner’s hose or canister cracks or holes, can also make a whistling noise, so keep looking for any damaged parts and fix them to prevent any noise.

Step 7:

Other factors that might cause a vacuum to abruptly get louder include trapped things such as tiny toys, coins, and hair, both pet and human.

Resolving the issue in these cases is easier as the cause is apparent. Simply remove the stuck item from the vacuum.

Step 8:

It is preferable to take your vacuum cleaner to a professional for repair or to get a new one if the noise comes from the motor. If the appliance is still under the company warranty, you can contact support to claim the warranty. 


Even though the design of modern vacuums has evolved tremendously, and while cleaners are now less loud than initially, they still need to generate a significant amount of noise to function effectively as air suction and hoovers are involved.

However, there are a few easy things you can do to maintain your vacuum cleaner functioning at its while preventing it from generating more noise than it needs to. These include cleaning the vacuum regularly, checking that the vacuum hose is not clogged, filters are clean, and any accessories are not broken or loosely attached.

Frequently Asked Questions

What is the cause of the crackling noise when using a new vacuum cleaner?

The crackling noise you hear when using a new vacuum cleaner is likely caused by dirt or dust particles stuck in the filter or hose. This can create a rattling sound as the vacuum suction attempts to move these particles.

Additionally, this could be caused by an unsecured piece of plastic or metal coming loose and hitting other vacuum components.

To fix this, check the vacuum’s filter, hose and other parts for any debris or loose pieces. You may need to remove and clean these parts if they are clogged with debris. Regularly clean and replace your vacuum filters according to manufacturer instructions, as this can help reduce noise and improve the efficiency of your machine.

Why is my vacuum cleaner making a weird noise?

When the vacuum cleaner is turned on for the first time, the motor turns gently to safeguard it. As the motor settles down in its place, a louder noise is produced. This can’t be regarded as a defect or malfunction with the product in question.

However, if the loudness is out of proportion or the vacuum cleaner makes specific noises, there might be other reasons, such as a dirty filter and a clogged vacuum hose. Kindly clean the filter after use to avoid such problems with your appliance.

Why is my vacuum making an air noise?

The filters linked to the vacuum build up filth through repeated usage and exposure to dust and debris. The layer of dust blocks the airway via the vacuum tube. The machine must work hard and make noise to move the air throughout the system. This might be a possible explanation for your vacuum making an air noise.

What does a vacuum leak sound like?

You will typically hear hissing noises coming from the motor when there’s a leak in your vacuum cleaner. This could also be described as whimpering or snivelling sounds. A more severe vacuum leak makes a suction-like noise like a big whirlpool in a small bottle.
