The vacuum cleaner began to suck poorly: the reasons why it hums, heats up and does not pull up dirt

Regular cleaning of the house with a vacuum cleaner allows you to create a special atmosphere of cleanliness and comfort, and reduce the concentration of dust in the apartment, which can lead to the development of allergic reactions. If problems are detected in the operation of useful equipment that efficiently removes dust particles and dirt from the surface of carpets and furniture, it is necessary to promptly identify the cause of the malfunction and begin troubleshooting. However, not every person has information about why the vacuum cleaner has stopped suction, so before starting repairs, you should definitely read the instructions included with the household appliance.

The main reasons for the reduction in debris suction power

In order to identify the cause of the breakdown and begin repairs as quickly as possible, it is necessary to carefully inspect the device to determine the factors that negatively affected the operation of the device. The following problems usually lead to a decrease in the air intake power, which is the reason that the vacuum cleaner does not suck up dust:

engine breakdown;
spare parts requiring replacement;
the presence of a large amount of small debris in the dust collector;
damage to the hose or brush;
dirty or clogged filter;
large debris getting inside the hose.

If a malfunction associated with poor dust absorption is caused by contamination or wear of components, the problem can be eliminated using accessible methods without resorting to the services of specialists.

Note. If the engine is damaged, repairing the device at home is very difficult. Carrying out high-quality repairs requires disassembling the housing, removing the motor, as well as the necessary knowledge and experience. In a situation where the malfunction cannot be eliminated, the device must be replaced.

Why does the vacuum cleaner get hot - Cleanliness Club

For any person, cleaning the house is an integral part of his life.
When cleaning any surfaces, it has become more than natural for us to use special tools and assistants. These include the most ordinary vacuum cleaner, which has already become an integral attribute of any housewife, since we simply cannot imagine cleaning carpets and other surfaces without it. But, like any equipment in our home, the vacuum cleaner also does not last forever. Over time, you may notice the first signals that the normal operation of the equipment is disrupted for some reason. One of the factors that can indicate a violation in everyday operation is an increase in the temperature of the blown air and the unit itself. If you start to notice that the vacuum cleaner is getting very hot, you should not hesitate, this is not a cold that will go away on its own. Most often, the first signals of failure only warn us about an impending breakdown and the need for capital expenditures to purchase a new unit. To avoid such troubles, you will need basic knowledge of technology and a little patience.

The first step is troubleshooting

If you feel that the vacuum cleaner is starting to overheat or, worse, is turning itself off, first of all, stop panicking and calm down. In such situations, you should take a sober and balanced approach to solving the problem. Remember right away - if you doubt whether you can cope with the task, it is better to contact qualified specialists or call customer service. Otherwise, you can simply ruin the device, which costs a lot of money.

So, you should always start with an accurate determination of the cause of the breakdown. Otherwise, it will turn out that the repair was not what was needed - and the cause was not eliminated, and time was wasted.

If the vacuum cleaner gets hot, the reason most often lies in the following factors:

Perhaps one of the filters in the vacuum cleaner, if any, is clogged
There is an obstruction inside the hose or inlet;
Engine breakdown, disruption of normal operation;
The garbage container or bag is filled to its maximum capacity.

Let's look at each of these cases separately.

Many vacuum cleaners are equipped with a wide variety of filters. The purpose of these filters is identical - they clean the air from dust, debris fractions and various contaminants. HEPA filters are especially common these days. Each such filter consists of small holes that allow you to trap debris particles larger than the holes themselves. Of course, when a certain amount of debris accumulates in the filter cells, the air flow drawn in by the vacuum cleaner will pass with greater difficulty due to obstacles that arise in its path.

It is precisely such obstacles that cause overheating of the electric motor in the unit. Firstly, the engine cannot create normal thrust, and secondly, much less air is supplied to it, which should, among other things, cool it, creating normal heat exchange with the environment. In this case, the vacuum cleaner has poor suction and heats up; to eliminate this type of malfunction, it is necessary to clean the filters or replace them, for vacuum cleaner models in which periodic replacement of filters is technologically provided.

It should also be noted that some vacuum cleaners have not one, but several filters. In addition to the inlet filter, they can be located in front of the engine to prevent dust and debris from entering the engine itself, or at the outlet to prevent debris from flowing back into the airspace of the room. Quite often this reason manifests itself in cases when a Samsung vacuum cleaner gets hot; models from this manufacturer are equipped with a large number of filters that users forget to clean on time.

We have all at least once encountered a situation where, while cleaning a room, the nozzle of a flexible hose became clogged with various objects - a plastic bag, a curtain, and the like. Approximately the same situation occurs when any object is sucked in that can create a kind of plug inside the flexible hose or at the inlet. Due to such a plug, the air flow can no longer pass normally, and accordingly the engine has to operate in an abnormal mode, which causes overheating, which is accompanied by the characteristic sound of the unit.

This is very noticeable, since in the case of significant overlap, the difference in the operation of the unit is noticeable. If such a situation was not identified immediately, then after a certain period of time, when heating of the air flow is detected, the flexible hose should be disconnected from the attachment point. If an object or debris does not clog the inlet, air will immediately begin to be sucked in normally. To fix the problem, sometimes it is enough to simply blow out the hose; in some situations, you will need any long and elastic object to remove the clog.

Please note that an object can damage the hose, so you should be very, very careful when choosing a cleaner.

There are situations when the vacuum cleaner engine heats up due to faults in the engine itself. There may be several reasons for this - this is the wear of individual components and parts of the engine, and interturn short circuits, which subsequently lead to serious breakdowns. The engine itself is a very expensive element, so disassembly and repair must be approached very carefully.

You should not break or try to pull anything out with force; as a rule, all models have fastening points that allow you to disassemble the device without causing the slightest damage to it. Pay attention immediately to the brushes; the graphite on them can easily wear out, which is why the pressing force weakens and the sliding contact has a much higher contact resistance. The result is heating of the engine due to the additional load, especially during engine start-up.

This problem can be resolved by simply replacing the graphite brushes. This situation is most common if the LG vacuum cleaner gets hot.

If the insulation of the windings is broken and an interturn short circuit occurs, during the engine start-up and operation, a circular fire can be seen in the frame holes in the commutator. Only a qualified specialist using special equipment can fix such a problem. If you decide to disassemble the engine yourself, be careful and extremely careful, since in most cases the housing of electric motors is made of light aluminum alloy.

Some users may wonder why the vacuum cleaner heats up during cleaning and the suction power decreases. The reason may be simply filling the garbage bag with waste to such an extent that the vacuum cleaner can no longer draw in air normally, and the engine does not receive the necessary cooling. It is important to remember that not all debris fills the bag equally; fine and heavy dust will quickly create a dense layer, creating a significant obstacle to the air flow.

Carrying out equipment diagnostics and troubleshooting

To find the reason why the vacuum cleaner does not pull, you need to disconnect the equipment from the electrical network and conduct a visual inspection of the device. It is imperative to check the correct settings in selecting the power mode on the control panel of the vacuum cleaner. If the drop in power is not associated with a change in settings, you should carefully disconnect all components to inspect them for damage and contamination. After diagnosing the product, further actions should be aimed at repairing the breakdown. Troubleshooting methods must be selected depending on the type of problem.

Emptying a Full Bin

A container filled with debris is a common cause of reduced dirt absorption and poor cleaning quality. Why the vacuum cleaner does not suck up dust well, what to do:

Empty the reusable bag from any accumulated dust.
If necessary, wash it in warm soapy water.
Rinse thoroughly and dry completely.
Install in its original place.

Paper waste containers intended for one-time use must be replaced with new products after they are filled with dust. After cleaning or replacing the dust bag, you should test the operation of the equipment. If cleaning the container does not bring the desired result, you need to carefully inspect the filters of the unit.

Checking filters

Worn or clogged filters often lead to decreased traction. And if the vacuum cleaner stops suction, what should you do in such a situation? To eliminate the malfunction that is causing the drop in suction power, the exhaust filter must be rinsed with warm water, removing dirt from the cells using a soft-bristled brush. If the part has never been replaced, it will need to be replaced. The fine filter should also be removed from the device, rinsed with clean water, dried well, and installed back.

Inspection of the nozzle and hose

If everything is in order with the dust bag and filters, you need to check that the corrugated pipe is connected correctly to the unit body, and also inspect it for damage. If cracks are found on the hose or the brush is damaged, worn components should be replaced with new spare parts. Poor dust absorption may be due to a clogged suction hose or nozzle. In such a situation, the spare parts must be cleaned of debris, and then checked for air permeability.

Ways to solve problems

Having considered why vacuum cleaners have poor suction and heat, it is worth familiarizing yourself with the solution to these problems.

Everything related to the electric motor cannot be repaired on your own. This requires specialist intervention. Vacuum cleaner manufacturers are trying to improve product quality by installing high-quality components and parts. And if they fail, then more often than not they have served their time. Therefore, there is no point in repairing them. In workshops they are simply replaced with new ones.

A burnt-out motor winding can be replaced, but this still reduces the quality of the motor. Therefore, experts recommend changing it or purchasing a new vacuum cleaner. The winding burns out for four reasons:

the bearings sagged, which caused the rotating rotor to sag, so it began to touch the stator winding, abrading it and removing the insulation;
overheating of the winding, which causes the insulating layer to burn out;
the collector becomes clogged;
Water got on the winding.

Problems with liquids often arise. If the vacuum cleaner is not washable and does not have an aqua filter, then it cannot collect spilled liquids. Especially if there is a paper bag installed inside the vacuum cleaner. With any protection, even a small volume of water will penetrate inside the motor and reduce its service life.

Troubleshooting the board is possible, but only in a workshop. Here you have to look for an element that has burned out or stopped functioning due to the end of its service life. It is usually changed. It is rare that the entire plateau has to be removed. But this also happens.

If the voltage in the house is low, then the solution is simple - install a step-up transformer.

Why the vacuum cleaner does not suck, but works: reasons

When the power of the device decreases, you should touch the body of the vacuum cleaner. If it is too hot, the engine is running under load. If overheating of equipment is detected, it must be turned off and not used until the cause of the problem is determined. To determine a malfunction that contributes to the strong heating of the unit and a decrease in suction power, you need to perform simple steps:

check the functionality of the equipment after disconnecting the hose. If the housing stops heating, the cause of the malfunction is in the pipe or brush;
inspect the inlet located on the body for the absence of large debris and other foreign objects;
test the functionality of the device after removing the dust container;
If the switched-on equipment continues to heat up, it is recommended to clean the filters from dirt or install new components.

Clean filters from dirt

In a situation where all components have been checked, but the equipment continues to heat up, the problem is a motor malfunction. To repair the vacuum cleaner motor, you will need to completely disassemble the housing and replace damaged parts.

We recommend:

Note! If the integrity of the winding on the coil is damaged, the problem can only be eliminated by purchasing a new household appliance or motor.

Checking the bag

The first thing you should do is check how full the bag is. If debris fills more than 2/3 of the container, the draft may become weaker or even disappear when you vacuum. The paper bag must be replaced with a new one, because... it's disposable. If the container is fabric, you can thoroughly shake it out and put it back into the guides, but it is better to rinse it in clean water and dry it.

As a rule, in modern models of equipment, the degree of contamination of the garbage bag is displayed on the body. The light indicator in the form of a light bulb will light up green if the container is still empty and red if it is time to replace it.

If you have done cleaning, and the vacuum cleaner still does not suck well, look at the power regulator; perhaps it was accidentally set to minimum, as a result of which the device does not draw air.

Why does a working device hum and vibrate a lot?

If during cleaning the vacuum cleaner begins to hum loudly and heat up, you should check the hose for blockages. Accumulated debris in the hose negatively affects the traction force and contributes to the appearance of loud sounds, hum, and strong vibrations that are uncharacteristic of the normal operation of the vacuum cleaner. You can clean the hose of foreign components stuck inside that are preventing the normal passage of air flow using a wire or a long thin object.

If you cannot get rid of the hum, you need to inspect the filters and dust collector. If these elements become dirty, you need to replace worn parts and empty the container of debris. Increased noise from the unit may be due to impeller imbalance, damage to bearings and other important components. If you suspect this malfunction, it is not recommended to carry out repair work yourself. Eliminating such breakdowns requires special equipment and skills.

To start

Before you pick up a screwdriver and take your vacuum cleaner apart, troubleshoot three common problems:

empty the clogged dust bin;
check clogged filters;
cracks in the hose or telescopic tube.

Check if the dust bin is clogged

If the bag is more than two-thirds full of debris, the suction power weakens, creating the feeling that it “doesn’t pull.”

The paper dust collector must be replaced with a new one, and the fabric one must be shaken out, rinsed in water and dried.

Make sure the hose, tube or brush is not clogged

If everything is fine with the bag and there is still no traction, check other components - brushes, telescopic tube and hose. The hose may be damaged - cracks, holes, clogged or not fully inserted into the housing.

Both small particles and large objects get stuck in the brushes, hose and tube: strings, napkins, handkerchiefs, rags, and so on.

Because of them, the garbage does not pass through well, the vacuum cleaner hums loudly, howls, buzzes and makes other inappropriate loud sounds, and it smells of burning or something else burnt. Usually, after removing the blockage, traction is completely restored.

Also check the components for wear: in some cases, suction is hampered by jammed motor bearings or even improperly seated brushes.

Looking for cracks in a corrugated hose

A hose with cracks creates air leaks and prevents the creation of vacuum to draw in debris.

We recommend replacing such a hose entirely, but there is also a temporary solution - inserting an adapter sleeve inside.

To do this, cut the pipe, insert a piece of plastic tube inside, clamp its joints with clamps and seal the cut with tape.

Cleaning the filters

A big mistake is to inspect the dust collector, but not check the cleaning filters: after each cleaning, the elements become heavily filled with dust.

One of the filters is located in front of the fan. For cyclone vacuum cleaners, as a rule, this is a foam rubber plate inside a plastic collapsible body. At the back of the case there is a mesh with small cells. The plate must be knocked out well and washed together with the filter in water.

The second, rear fine filter is installed on the exhaust of the vacuum cleaner. Most often it is a separate box with a large number of cells. The cells should be cleaned with a soft brush and rinsed under running water.

If your vacuum cleaner is equipped with a water aquafilter, do not forget to clean it after each cleaning: disassemble it, wash each element and dry it thoroughly. This must be done even if there are no problems with the vacuum cleaner, so that bacteria and fungi do not multiply in dirty water.

We remember whether the equipment has overheated

If the vacuum cleaner gets too hot, the electronics can automatically turn off the electric motor. It is enough to wait 20-30 minutes for performance to be restored.

Equipment can overheat not only due to long hours of operation - there are other reasons:

got hot because the network cable was damaged;
the armature collector is clogged;
bearings and brushes are worn out;
The electronic unit or start button has failed.

The most serious problem with a vacuum cleaner is motor failure. To identify it, you will have to disassemble the device.

Ways to prevent problems from occurring

To reduce the risk of malfunctions that reduce the suction power of the device, you must follow these simple recommendations:

prevent engine overheating;
regularly clean the garbage container from dirt accumulated during cleaning;
do not use the device to collect construction waste during indoor renovation work;
promptly replace and clean filters;
move the device during cleaning using a special handle;
do not bend the hose during operation and storage of equipment to prevent cracks or tears from appearing in the corrugated product;
do not clean parts with aggressive cleaning agents;
Do not vacuum if the plug or cord is damaged;
If you notice smoke or an unpleasant burning smell emanating from a working device, you must promptly seek professional help.

By following these simple tips, you can significantly extend the life of the unit, which is an indispensable and faithful assistant in maintaining cleanliness in the apartment.

What to do

The reduction in power mainly depends on the same reasons. To avoid problems, you should adhere to several nuances when operating the vacuum cleaner:

avoid hose kinks during operation;
do not vacuum construction waste;
clean or change filters every six months;
clean the dust container in a timely manner;
If the case overheats, without certain knowledge, do not repair it yourself, but contact a service center.

If you follow these simple truths, you can use a vacuum cleaner to clean your room for a long time.

If the vacuum cleaner has reduced its suction power, this is not a reason to take it to a service center. Many problems can be solved using accessible methods; the main thing is to follow the instructions.

General structure of the vacuum cleaner

Regardless of the design and operating features, vacuum cleaners consist of the following components:

collection device (nozzle);
channels and hoses through which garbage enters the dust collector;
electric motor;
dust collector (bag).

Modern vacuum cleaners are supplemented with an aqua filter, which also reduces suction power.

The housing, in addition to the motor, hides a vacuum compressor, filters and control units. Some models are complemented by an alarm system and other devices.

Mechanical damage to the gadget

The source of why the vacuum cleaner does not suck well can also be external and internal minor damage. It could be:

crack in a hose or pipe;
a large dent on the body, as a result of which the “insides” of the vacuum cleaner were damaged;
brush breakage.

The easiest way out of such situations is to replace the broken part of the device with a new one. It won't take much time and will allow you to use it right away. Or the unit should be taken to a service center to diagnose the breakdown and fix it.

What to do to stop noise from appearing

In order to prevent the occurrence of strong noise in heating equipment, it is necessary to take into account the main points when designing:

Modern equipment for regulating flow speed is quite powerful. Even a small wet unit with a low noise level can sufficiently provide comfort in a building with a small area. Correct installation, which was carried out according to the manufacturer's instructions, can greatly improve the performance of the pump.

During installation, it is important to remember that the power unit of models with a “wet” rotor can only be installed horizontally. If you choose a different installation method, there may be problems

To prevent extrusion and damage to small parts inside the pump, it is advisable to attach a filtration device with a deep cleaning function in the area in front of the pump. If the parameters may change, or there is no exact data on the dimensions of the room, the best choice would be models with possible changes in operating modes. The liquid entering the pump should not exceed a temperature of 65 degrees

Therefore, the pump must be installed on the return part of the pipeline.

Washing washable and reusable filters

Some filters are “reusable” and their manufacturers allow the filter to be washed under running warm water for cleaning purposes. Read the instructions for your vacuum cleaner carefully. There may be additional information on washing the filter there. You should not wash paper filters, as they may become wet and lose their filtering properties.

If washing the filter does not bring satisfactory results, then most likely the filter is worn out and needs to be replaced.

High-quality HEPA filters can not only visually keep the room clean and protect the internal parts of the vacuum cleaner from wear, but also clean the air from the smallest particles, microbes, and microorganisms. The service life of filters, according to the recommendations of vacuum cleaner manufacturers, is usually 6 months and may be reduced depending on operating conditions.

Any questions ask me, I will help!

If your vacuum cleaner has poor suction and the reason is hidden in the rod or pipe, then while cleaning you will hear a characteristic loud hum. If there is something you don’t understand, write to me!

Search for reasons

Diagnostics always helps to determine the cause of poor dust absorption. The procedure can be performed by anyone who knows how to use a screwdriver. However, it may not come to disassembling the vacuum cleaner if the breakdown does not affect the electrical part of the unit.

Often, a superficial diagnosis allows us to identify the following causes of poor absorption:

During cleaning, a large object was pulled in and got stuck inside the hose or telescopic handle;
the dust collector has not been cleaned for a long time and is completely clogged with debris;
the filter on the exhaust of the vacuum cleaner is clogged;
The corrugated hose, working nozzle or telescopic handle is damaged.

If these causes are not identified during diagnosis, the problem lies inside the vacuum cleaner. The weakening of the suction force occurs due to a decrease in the power of the electric motor. The reason may be brush wear, contamination of the armature commutator, loose bearings, or the formation of thick dust deposits on the fan impeller. A loss of power sometimes occurs when an electronic unit fails. As a result, the control wheel cannot change the engine speed or it begins to “float”.

To carry out superficial diagnostics, all components are disconnected from the vacuum cleaner. The inspection begins with the working nozzle, then moves on to the telescopic handle and corrugated hose. The components must be free of cracks, holes and other defects. It is important to check the inside for any stuck objects.

The dust collector and filter on the exhaust of the vacuum cleaner are further checked. These two components greatly influence the suction power. The disposable filter is replaced with a new one, and the reusable fabric bag is washed well.

Cyclone vacuum cleaners have an additional foam filter between the motor and the garbage container. The plate becomes heavily clogged with dust and needs to be washed. There is another filter on the exhaust. If it is clogged with dust, the exhaust air becomes obstructed and returns to the fan, reducing the suction power.

Reliable vacuum cleaners from Miele

Miele products have an impeccable reputation all over the world. If you dream of a vacuum cleaner that can easily clean the entire house, will look beautiful and will appeal to all family members, feel free to choose a model from the Miele catalog. She has the most incredible helpers for maintaining cleanliness:

universal three-in-one transforming models;
traditional vacuum cleaners with a dust container up to 4.5 liters;
equipment with a vertical body and a control panel on the handle;
robots.

Each model is unique in its own way. Some boast ultra-light weight, others boast high suction power, and others boast a variety of interchangeable attachments for caring for different types of surfaces. But the main thing is that all models undergo strict quality control and serve for many years!

Should you buy a new vacuum cleaner bag?

The second most popular reason for loss of power lies in the overfilling of the dust collector of the vacuum cleaner. If your model of vacuum cleaner uses dust bags, and you are sure that you have not changed the bag for a long time, then it is worth replacing the bag. This should only be done when the device is disconnected from the network.

The bag can also become clogged over a short period of time, for example, if pets live in the room being cleaned. Remember that the bag not only collects dust, but also in its pores, the material from which it is made, retains its small fractions, participating in a complex air filtration system. It is impossible to clear dust from pores by shaking or washing.

Faulty components

If the filters and dust bag are in good working order, but the vacuum cleaner still cannot cope with its basic functions, you need to check the hose and brushes. They may be mechanically damaged or poorly connected at the mounting points. The hose is cleaned using soft wire along the entire length of the hose. Usually, a loud noise when the vacuum cleaner is running indicates a problem in the hose. Debris can accumulate on the brushes, so it is necessary to periodically clean them so that the roller rotates easily. If necessary, you can lubricate bearings that may have jammed during operation. If the roller is very worn, it should be replaced.

We also recommend reading the article on how to clean a vacuum cleaner with your own hands.

Full dust bin

An overfilled dust container is a common reason why a vacuum cleaner pulls very poorly. And it’s the easiest way to deal with it.

If the vacuum cleaner has a plastic container, it is recommended to empty it and wipe it first with a damp and then a dry cloth.
A bag-type cleaning gadget like the Rowenta RO5227EA is even easier to clean: you just need to replace the disposable tank with a new one. But, if reusable microfiber or fabric bags are used, they need to be shaken out and washed.

The dust container should be cleaned as it becomes dirty. In this case, the question of why the vacuum cleaner sucks so poorly will not arise.

Search for reasons

Often, a superficial diagnosis allows us to identify the following causes of poor absorption:

During cleaning, a large object was pulled in and got stuck inside the hose or telescopic handle;
the dust collector has not been cleaned for a long time and is completely clogged with debris;
the filter on the exhaust of the vacuum cleaner is clogged;
The corrugated hose, working nozzle or telescopic handle is damaged.

Cleaning the filters

Moving further in troubleshooting, you need to check the cleanliness of the fine filter (installed in front of the motor) and the HEPA exhaust filter, which is attached to the back of the case behind a plastic grill. As for the first filter, it must either be completely replaced or washed with water and dried, which depends on the versatility of the material. The HEPA filter, as a rule, needs to be replaced every 50 hours of operation of the equipment so that the vacuum cleaner’s traction does not disappear at the most inopportune moment. Have you checked it, replaced it, but the vacuum cleaner, as before, does not collect and suck up debris well? We look at the following elements of the suction system.

How to understand what is causing the vacuum cleaner to heat up?

The most common causes are: dirty filters, full dust containers, broken components, malfunctioning engine. How to understand what exactly affects the unit?

It is better to adhere to a certain sequence and use the method of eliminating inappropriate items:

For a vacuum cleaner that stops heating if you disconnect the hose and start it, the reason may be in the nozzle or in the pipe itself.
Next, check the unit inlet for any additional obstructions. If everything is in order, move on to the next point.
Depending on the model of the vacuum cleaner, carefully remove the container where all the small debris and dust fall: a bag, a container. Let's start the device and see how it works.
Another reason why the vacuum cleaner overheats and turns off may be filters. Just clean them carefully.
The last point is engine failure. In this case, the vacuum cleaner may overheat, causing it to turn off on its own.

In most cases, you can make the repair yourself. This does not require deep knowledge. However, there are situations in which only a qualified specialist can cope with the task.

Engine malfunction

A breakdown of this type is critical and the most dangerous for a vacuum cleaner. It is not difficult to diagnose - the device gets very hot even immediately after switching on and with minimal load. In addition, during operation, the vacuum cleaner itself periodically turns off.

To eliminate the problem, which is expressed in engine failure, it is best to contact qualified service workers for repairing household appliances. If you have skills in working with household appliances, you can remove the housing and “ring” the motor circuit with a multimeter. The most common problem is a failed fuse. In this case, it must be replaced with exactly the same one.

If there is a break in the coil winding, you will have to buy a new motor, which is not economically profitable - it is better to buy a new vacuum cleaner right away.

Some vacuum cleaners have a safety valve.

, which serves to capture air when the hose is clogged in order to protect the engine from overheating.

The valve can become jammed by a small object caught in it and it will leak air. For this reason, suction power may also drop.

. It is worth inspecting it and if a stuck object is detected, remove it from the valve.

Another problem with new vacuum cleaner models is the low-density paper mesh in the cartridge filter. It gets clogged within a year and is impossible to clean. This may also be the cause of poor absorption

. To solve the problem, you just need to throw it away, leaving only the foam rubber.

If you want to avoid problems, take proper care of your equipment and use it for its intended purpose.

Checking the dust container and filters

Most modern models have a special indicator on the body that notifies you when the dust collector is full. If your equipment does not provide it, then do not forget to periodically check the bag/container yourself. Please note that some vacuum cleaners begin to suck up dust poorly even when the bag is 70% full, and sometimes in such situations the traction completely disappears.

As for filters, there are two of them in the vacuum cleaner:

Fine cleaning. Located in front of the engine (usually on the rear panel). It needs to be cleaned regularly, for which you need to remove the part and rinse it under running water (read the instructions carefully before cleaning the filter). If this does not help, then you should purchase a new part.
Exhaust filter. Does not require cleaning, but needs to be replaced every 50 hours of operation of the device. If you do not change the exhaust filter for a long time, it will become clogged and the quality of traction will deteriorate significantly.

The vacuum cleaner heats up and turns off. What is the reason?

Even if you have a lot of free time, turning off the vacuum cleaner while cleaning is very annoying. This can be confirmed by all owners who have at least once had to finish cleaning with a broom and dustpan. If you notice that the body of the vacuum cleaner gets very hot, after which the device turns off and refuses to work until it cools down completely, it is important to correctly determine the reason why this is happening. To make it easier to understand, you first need to understand the principle of operation of vacuum cleaners.
