In modern life, housewives strive not only for cleanliness, but also for comfort. This aspect is also important when choosing household appliances. A device such as a vacuum cleaner should not only be powerful and functional, but also be as silent as possible.
What to do if the vacuum cleaner whistles loudly?
If your vacuum cleaner makes a whistling noise, it usually means it isn't drawing enough air. This problem is usually caused by a full dust bin or dust bag. Check them first and replace them if necessary. If this is not the reason, then some component of the device may be clogged.

First of all, we clean the filters
Most often, the device is noisy due to the fact that air does not get to the motor, and therefore it is operated in overload mode. The reason for this phenomenon is trivial: the owners have not cleaned the filters for a long time and do not empty the contents of the bag in which the sucked debris is collected in a timely manner. By removing the clogged filters and emptying the garbage bag, you can easily solve the problem.

There are three types of filters used in household vacuum cleaners:
1. Primary – collecting debris and large dust particles that accumulate in a bag made of paper or fabric;

2. Nera – for collecting microparticles up to 0.3 microns in size, preventing them from getting on the device’s engine and extending its service life. They are:
- disposable, made of paper. Some people reuse them, cleaning them with a jet of compressed air. This method restores the filter by 80%. For an ideal result, it is better to replace it;
- reusable, made of polymer materials. They are washed and dried. But this does not protect them from harmful bacteria and germs.

3. Aquafilter or water filter. The principle of operation is simple: dust particles are wetted, become heavier and settle inside the dust collector. The filter consists of a container for collecting large debris, dust particles and nerf. They clean it in this way: the container is washed, and the oil is washed and dried, or vacuumed and put in place.

4. Cyclone filter, which consists of a container and a filter. The dust is exposed to an air flow that picks up the smallest particles and sends them into a special transparent plastic dust collector. It must be cleaned after each use of the vacuum cleaner. Having freed the container from debris, the filter is washed, shaken out, knocked out or blown out.
Industrial and some expensive household models of vacuum cleaners have an automatic filter cleaning function. But even in them, due to active use, nera can become clogged. We already know how to clean them. From time to time the filter needs to be replaced with a new one.

We recommend! It is advisable to do this not in the apartment, but outside, so that dust with microbes does not again make the room dirty and harm your health.
Sometimes the vacuum cleaner not only runs loudly, but its suction power decreases. After cleaning the filter elements and replacing them, everything returns to normal.
Important! It is not unnecessary to check the suction hose and brush. Filled with scraps of paper, cellophane, and large objects, they can also cause the vacuum cleaner to hum.
How to clear the blockage?
The vacuum cleaner is very loud, even buzzing annoyingly, but you don’t know what to do? You can clean the filters yourself or repair the engine.
Advice! Before making repairs, unplug the equipment.
Cleaning filters
The equipment may make noise because, due to clogged filters, air masses do not reach the motor. The problem can be fixed as follows:
- primary fabric or paper elements are completely replaced;
- disposable HEPA filters are cleaned with a jet of compressed air or replaced;
- reusable polymer HEPA filters are washed and left until completely dry;
- aquafilters are cleaned by washing the container, HEPA and drying;
- The cyclonic filtration elements are cleaned after each cleaning by emptying the container, shaking out, knocking out or flushing with HEPA.
Expensive models have automatic filter cleaning, but after the expiration of time, the part must also be replaced.
Advice! It is better to carry out cleaning outside or on the balcony so that dust and germs do not enter the room again.
How to change the filter?
If cleaning the filter elements does not help, you need to do the following:
- Wipe the dust container with a damp cloth and remove debris;
- Thoroughly clean the ribs and niches on the body - dust also accumulates there;
- Check the fasteners, since debris and dust reduce the quality of fixation of the dust collector, which leads to wear of the bearings;
- Blow out the place where the motor is attached, removing the dust collector.
Advice! Tilt the body in different directions, adjusting the suction power - this will remove dust particles from the engine compartment.
Navigation problems
Failures in the navigation system of the robot vacuum cleaner may be indicated by cyclical circular drives, constant collision with obstacles, or returning to the base immediately after launch. From the list of possible malfunctions, you should first of all exclude clogging of orientation sensors, which may vary depending on the design of the robot:
- IR obstacle detection sensors (usually hidden under tinted bumper glass);
- ultrasonic and edge sensors - in small windows on the bumper and on the side;
- fall sensors - along the perimeter of the bottom;
- laser rangefinder - a “puck” with slots on the robot cover;
- overview video camera - in the recess on the front panel.
Each of the detected sensors must be blown out and wiped with a dry cloth. You should also check the functionality of the wheels - a clogged rotary roller often causes the vacuum cleaner to move backwards and then turn off.
Another common problem involves a black pattern on the carpet or floor that the robot perceives as an insurmountable obstacle, or black furniture that the robot constantly crashes into at full speed. Such navigation features are explained by the shortcomings of orientation sensors: IR fall sensors perceive black stripes on the floor as gaps that need to be avoided, and IR obstacle detection sensors, on the contrary, perceive black furniture as free space. You can avoid such incidents by initially choosing a robotic assistant with an advanced navigation system based on lidar, echolocator or video camera.
Let's look at user reviews
Vacuum cleaner users, mostly our lovely housewives, are trying to figure out the cause of the hum and ask a lot of questions. Here are just two popular questions of the same type: “Tell me, why does the vacuum cleaner hum loudly?” and “My Samsung vacuum cleaner is noisy, what should I do?”
Photo 9. A reliable Samsung vacuum cleaner needs constant filter cleaning
It turns out that modern Samsung models have special built-in sensors that regulate motor overheating. If the vacuum cleaner turns off during a long period of operation, it needs to rest until the engine cools down. If this rule is ignored, during further operation, it may fail. In addition, the Samsung 1600 w model is equipped with a large number of filters that need to be cleaned periodically.
Also read our article about Samsung vacuum cleaners equipped with an Anti Tangle turbine.
After reading reviews on forums about a vacuum cleaner that began to hum loudly, users draw conclusions for themselves. Now they try to fill the dust bag only halfway, for fear of ruining the engine. Now their vacuum cleaner works silently.

Most popular damage
If you do not clean the dust collectors in a timely manner, do not change the filters, or use the device without an aquafilter to collect moisture, you will find a malfunction.
The filter is clogged
Damage occurs as a result of infrequent cleaning of the dust bag or filters. Has your household vacuum cleaner suddenly become very loud? The problem is explained by operation in overload mode, which intensifies the sound. Check the hose to see if large debris, dust bunnies, hair or animal fur may have gotten into it.
The bag is overflowing
Dust collectors have a certain filling limit - up to 80%. Disposable bags should be changed after each cleaning, and fabric bags should be washed thoroughly. To avoid clogging, before work, check the quality of fastening of parts, attachments and dust collectors.
Failure of one or more components
Excessively loud noise can be caused by damage to the motor, impeller, brushes, motor, bearings and commutators. When everything is in order with the filters and bags, but there is a hum, contact the service center. Self-disassembly and repair will lead to a complete stop of the device.
Engine defect or malfunction
If there is a manufacturing defect in new equipment, the buzzing appears from the very beginning. According to the Consumer Protection Act, you can replace your vacuum cleaner within 14 days. If the breakdown occurs later, you have the right to free repairs at the manufacturer’s service center.
Repairing the device engine

And now the filter has been cleaned, one of the reasons has been eliminated. We plug in the vacuum cleaner, but it still hums like an airplane, the noise level of the device is off the charts. Even an inexperienced technician will say that the problem lies in bearing wear.
If the filtration system is heavily contaminated, dust entering the engine compartment adheres to moving parts. When working “dry”, the unit begins to hum or whistle. If this is discovered in time and you begin to solve the problem, you can only get away with grease (it dries out quickly) or replacing the bearings.
Photo 8. General view of the engine of a modern vacuum cleaner
Well, if this doesn’t help, you should pay attention to the motor windings or its other elements. After unscrewing the cover with a screwdriver, you need to pull out the motor and shake the shaft with your fingers. If play is observed, everything becomes clear: the bearings, due to untimely cleaning of the filters, have become unusable.
Usually the front one fails first, on which the impeller (plastic or aluminum) depends. We disassemble the vacuum cleaner motor, remove the impeller, wash it in hot water with powder to remove adhering cement dust, dry it and put everything back together. Moreover, be extremely careful, since the impeller is crushed or even bursts from any pressure.
If this part is broken, replacing it is a mission impossible. The services do not change them; the motor comes from the manufacturer already with an impeller. A new motor will cost $30-40, and you need to look for the original - in the catalog.
We recommend! Although the Chinese equivalent motors are cheaper, it is better not to buy it. Do not forget the truth that the miser pays twice.
And if the equipment is old, purchased a long time ago, there is no point in repairing it. It makes sense to buy a new vacuum cleaner.
Typical Causes of Loud Noise
Does your vacuum cleaner vibrate and hum suspiciously loudly when running? There are several reasons for this problem:
- accumulation of large debris in the hose;
- compressor malfunctions;
- engine failure;
- clogging of the filtration system;
- malfunctions of electronic components;
- damage to bearings and commutators;
- brush abrasion;
- impeller imbalance.
Important! Sometimes, when there is excessive noise, the body of the device heats up, vibrates, and it periodically turns off.
The main causes of breakdowns and recommendations for safe operation of the vacuum cleaner
The main causes of breakdowns are incorrect or careless operation of the device and insufficient care. In order for the vacuum cleaner to last longer, it is important to perform simple preventive actions:
- Monitor the cleanliness of the filter elements - collect dirt, wash if necessary and change on time. Using a vacuum cleaner with damaged filters will sooner or later lead to engine failure;
- lubricate and promptly replace bearings with new ones;
- do not drop or hit to avoid mechanical damage - chips, cracks;
- store correctly. A suspended or unsuccessfully twisted corrugated hose will sooner or later break, high humidity in the room or too low temperatures contribute to the failure of electrical contacts, etc.;
- read and follow the operating instructions.
It is important to protect not only the vacuum cleaner, but also yourself: under no circumstances use a device with a damaged housing or power cord insulation - this could result in electric shock.
Why did the vacuum cleaner begin to hum loudly when working?
Modern requirements for household appliances set fairly stringent requirements for the permissible noise level. That is why, if the noise level of a working vacuum cleaner has become significantly higher, this should be a signal that it requires additional attention.
The main source of noise from a running vacuum cleaner is the engine. An increase in the volume of a running engine indicates that it is operating at increased power.
Long-term operation in this mode leads to overheating of the engine, as evidenced by an increase in the temperature of the air leaving the vacuum cleaner.
This can cause engine failure and subsequent costly repairs.
The vacuum cleaner is making a loud noise: what can you do?
If the vacuum cleaner starts making a loud noise, what can you do to avoid calling a technician? To begin, simply disconnect the hose from the vacuum cleaner. If the engine stops making noise, then a blockage has formed either in the hose or in the brush/nozzle.
You can clean the hose yourself by using a cable that plumbers use when cleaning sewers. In addition, it is necessary to clean the brush, on the bristles of which fur, hair, dust and other debris accumulate.
All this leads to the fact that the air is poorly absorbed, the thrust weakens, and it is necessary to increase the engine power.
Important:
Before carrying out work, be sure to turn off the power to the vacuum cleaner by unplugging it from the network.
If the vacuum cleaner continues to make noise, the filters need to be cleaned and replaced. In this case, it is necessary to clean the vacuum cleaner body from dust:
- The chamber in which the dust collector is located must be wiped with a damp cloth and the debris accumulated there must be removed.
- Clean all the cracks, ribs, and niches on the vacuum cleaner body where dust may accumulate.
- Inspect the place where the dust collector is attached - it should be clean; dust and sand particles will prevent the dust bag from being tightly attached. Through leaks, dust will enter the motor, causing increased wear of the bearings.
- Blow out the engine compartment by disconnecting the dust collector. In this case, the housing must be tilted in different directions, changing the suction power - this will allow you to get rid of debris and dust trapped in the engine compartment.
If after this the engine continues to make noise and does not suck up dust well, you must contact a service center.
Before using the vacuum cleaner, check that all parts are in place, the filters fit tightly and there are no gaps through which dust can enter the engine compartment. In addition, loosely installed parts due to vibration will cause additional noise and may fail over time.
