Often when cleaning, the vacuum cleaner begins to suck air poorly and loses its ability to collect debris. The problem can usually be easily fixed by cleaning the filter. But if the lack of traction is due to a serious breakdown, the device will have to be disassembled. We'll tell you what to do if the vacuum cleaner doesn't suck well in this article.

So, let's go!
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.
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.
Problems requiring repair
Without basic knowledge of electrical engineering, diagnosing the cause of an engine malfunction is quite difficult. It must be removed from the housing, disassembled and all circuit elements tested with a multimeter.
The motor winding burns out
If the engine is fully operational, it may spark slightly due to dust getting on the brushes (and smells burnt). But strong sparking is already suspicious.
One of the reasons for sparking may be a short circuit in the armature winding: then it is necessary to rewind or replace the rotor. The stator winding is checked by measuring the resistance - if it is different in several parts, the winding is rewound or changed.
Graphite brushes are worn out
The brushes no longer fit closely to the commutator contacts for two reasons: wear and low-quality materials. Poor contact negatively affects the starting and further operation of the engine.
The fact that the brush has become unusable can be determined by examining it. Most often, replacing the carbon brushes will help. If you cannot remove it, change the springs and brush holder.
Thermal fuse problems
If a fuse fails, it must be replaced.
Inspecting the vacuum cleaner and finding the cause of the malfunction
The vacuum cleaner has started to have poor suction, what should I do? There are just a few of the most likely causes for this problem. These include:
- dust bag overfilling;
- filter contamination;
- breakdown of components;
- engine failure.
All these factors can be easily corrected on your own. For the same reasons, there may be a problem with the suction of not only a dry cleaning device, but also a washing vacuum cleaner. Before work, you must disconnect the unit from the power supply. Next, you need to inspect the vacuum cleaner itself. A primitive problem of poor suction is setting a weak mode. This situation happens quite often. It arises from the inattention of the person using the vacuum cleaner. Having immediately set the necessary parameters, many housewives do not think any more about setting them up. Meanwhile, the lever is quite easy to switch if you accidentally hit it when moving it from place to place or even while cleaning. If this is not the case, you should proceed to further steps to repair the mechanism.
The next step is to disassemble the vacuum cleaner into components. The hose with the brush is disconnected and the lid of the device is opened. Next, diagnostic actions proceed according to the following scheme: inspection of the dust bag, filters, parts of the vacuum cleaner and its engine. The end of the event will be successful if a malfunction is found.
Question answer
What are the main reasons for a vacuum cleaner to overheat?
- clogging or damage to components,
- dust bin overflowing with garbage,
- engine malfunction,
- dirty filters.
Malfunctions should be checked in the following order:
- disconnect the hose - if without it the device heats up less, a blockage or kink does not allow air to flow, or the problem is in the telescopic tube;
- inspect the inlet of the vacuum cleaner for foreign objects;
- check how the device works without a dust collector;
- examine the condition of the filters;
- check the engine.
Why did the vacuum cleaner become loud?
Engine breakdown, failure of one or another component, bag filled with garbage (dust penetrates into the engine compartment).
If the engine is seriously damaged, it is better to purchase a new vacuum cleaner: replacing the motor is not economically feasible.
Which vacuum cleaner is better: bagged or with a container?
Advantages of bagged vacuum cleaners
Experts say that a bag – if, of course, it is made in compliance with certain technologies – is a more hygienic dust collector than a container
. The fact is that a bag made of multilayer material is not only a dust storage, but also part of a filtration system.

What to do if the vacuum cleaner does not suck up dust well
First you need to find the cause, then eliminate it. It happened that the suction power dropped during operation, for no apparent reason. Surely, either the child turned the power control on the body, or they themselves made an awkward movement. The suction power drops instantly only in the event of an accident with the motor, a pipe rupture, or a lack of power. In other cases, it decreases gradually.
Vacuum cleaners come in different types. Horizontal ones are easier to treat - all their canopies are located within reach. What to do if the power of the robot vacuum cleaner is lost? First of all, you should empty the contents of the dust container and inspect the nozzles. Often the free movement of the central brush is lost; it jams due to windings in the fastening points. If the roller is standing, it does not throw dirt into the vacuum gap, it blocks it, reducing the already low suction power. Why your vacuum cleaner won't pick up debris may depend on the condition of the side propellers and the broken latex tape that directs dust into the opening.
If the robot vacuum cleaner works but does not suck up dust, for another reason, it is determined by the master after examining the electronic programming system and the condition of all components. The machine may not be powerful enough to clean carpet. The smaller the residual charge, the smaller the suction capacity. If the vacuum cleaner works, but does not suck up dust, and runs to recharge a few minutes after starting, the reason is a dead battery. This happens a few months after the start of using the gadget.
What to do if your upright vacuum cleaner loses suction power? Please note that this is a cyclone vacuum cleaner. A filter is installed above the dust collector to prevent dust from entering the engine compartment. The cyclone of such models is very small. Dust settling is not as effective. It simply does not have time to compact and rises upward with the air. And there is a filter, which instantly became overgrown with sticky dust, preventing air from passing through.
The theory that the filter in a cyclone does not clog does not work in a small space. If a cordless vacuum cleaner has lost suction power and the dust bin is almost empty, what should you do? That's right, disassemble the cyclone assembly, pour out the dust, and shake the foam until the pores are free. This can happen several times during one cleaning. In addition, there is a battery here again, and it provides less energy the more discharged it is. From experience, at the end of the charging cycle, the power of the vacuum cleaner dropped noticeably, even with a new battery.
A vertical vacuum cleaner, battery-powered or mains-powered, does not suck up dust well over time, what should I do? Check the brush roller, it may become thick from curled hair and fur and block the vacuum hole. You need to remove the roller, use a utility knife or scissors, clean the rod, and release the bristles. What to do if this does not help, the vacuum cleaner does not suck up dust? Check the condition of the transition elbow from the brush to the pipe and the cleanliness of the air channel before entering the cyclone. Gradually, the air duct becomes overgrown with sticky electrified dust, and its cross-section decreases. Already little energy is wasted irrationally.
Every time the vacuum cleaner starts to suck poorly, the user asks the question, what to do? Look for the reason. Often it lies on the surface. It’s worth changing the nozzle, adjusting the power, and a lot changes. While working, you should listen to the sound of the instrument. So, the changed nature of the noise can give a clue. that something massive got into the pipe, which is why the suction power dropped, and the body of the vacuum cleaner began to heat up suspiciously. Of course, you urgently need to stop work and check where the object is stuck, remove it with a stick or wire.
What should you do if sparks fly out of the vacuum cleaner during operation, smoke comes out, and there is a smell of melting plastic? Stop, remove the canopies, clean the body from adhering dust and contact the service center.
In any case, if the vacuum cleaner does not suck up dust well, there are objective reasons for the decrease in the power of the device. The faster they are installed, the less expensive it will be to repair the instrument. What to do? Read the instructions and follow the advice of experts.
Engine damage
The most serious reason for loss of power and reduced traction of a vacuum cleaner is problems with the engine. Unfortunately, they are quite common on inexpensive devices. Manufacturers initially set aside a short motor life in order to stimulate constant demand for their products, since the cost of the motor is comparable to the cost of a new device.
But there are different problems with an electric motor. For example, it is quite possible to fix a breakdown associated with a broken wire contact or a blown fuse yourself. But more serious repairs are best left to specialists.
In any case, reliable and trouble-free operation of household electrical appliances depends on timely care for them. The procedure and frequency of performing specific equipment maintenance activities is always specified in the operating manual. Ignoring the manufacturer's recommendations is fraught with problems at the most inopportune moment.
