Vacuum cleaner bad suction or not pulling air. what to do
If during cleaning you notice that the vacuum cleaner poorly sucks the air or does not pull the garbage at all, you should immediately try to find the cause of the malfunction. Sometimes it is trivial. contamination of the filter, and sometimes the lack of traction is caused by a more serious failure. Next we will tell the readers of the site Sam Electric, why can disappear suction and what to do to repair the technique with your own hands!

The basic construction of a vacuum cleaner
Whatever the design and operation of your vacuum cleaner, it is made up of the following components:
Modern vacuum cleaners are supplemented with an aquafilter, which also reduces the suction power.
The body, in addition to the motor, hides the vacuum compressor, filters and control units. Some models are equipped with alarms and other devices.
The vacuum cleaner is heating and the suction power has dropped. what’s the reason??
Why the vacuum cleaner heats up or why it doesn’t pull the trash when cleaning?? Devices often break down due to improper use. Repair of equipment is sometimes not a small amount of money. Buying new is even more expensive. To prevent breakdowns, you need to follow the recommendations for care. And if there are already malfunctions, we can find out the causes and try to solve the problem ourselves.
The most common causes are: dirty filters, filled dust canisters, broken components, malfunctioning motor. How to understand what exactly affects the unit?
It is better to adhere to a certain sequence and use a method of eliminating unsuitable items:
- In a vacuum cleaner that stops heating if you disconnect the hose and run it, the cause may be in the nozzle or in the tube itself.
- Next, check the inlet of the machine for 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 fine debris and dust falls: bag, container. Start the machine and see how it works.
- Another reason why the vacuum cleaner overheats and shuts down may be the filters. Cleaning them gently is sufficient.
- The last point is motor malfunction. In this case, the vacuum cleaner may overheat, which can cause it to turn off on its own.
In most cases you can do the repair yourself. It does not require deep knowledge. However, there are situations in which only a qualified technician can cope.
What causes the drop in suction power?
The roots of the problem of why the vacuum cleaner does not pull, the same as in its heating. Occurs with units designed not only for dry cleaning, but also for wet cleaning. Poor air flow is the first signal of malfunction.
If the vacuum cleaner is not sucking up the dust, what to do?? With the help of diagnostics, it is necessary to understand the cause of the malfunction:
- Unplugging the machine is a must.
- Then do an inspection.
- Check the mode. You may have accidentally snagged the lever or the set parameters are off.
- If this is not the reason, then we need to disassemble the device. Let’s take a Samsung vacuum cleaner, for example, which does not suck up dust. Disconnect its components: brush, tube. We remove the housing and examine the insides: dust canister, filters, motor, other parts.
If the cause of the problem is found and it is related to the above items, you can begin to fix it.
Let’s start with the dust bag
Why the vacuum cleaner does not suck the dust?? Often the answer to this question we see when we remove the dust bag from the device. Older models do not have a special indicator that shows the degree of filling. So from time to time it is necessary to check yourself. The intake force can be reduced or even eliminated if the dust canister is 70% full or more. Therefore, it is worth replacing it.
When cleaning, pay attention to the material from which the dustbag is made. If paper, it must be thrown out and replaced with a new one. If it is a cloth vacuum cleaner, shake it well and wash it without using soap. Once dry, it can be put back in place. These bags are reusable, but it is necessary to respect the order of cleaning: if you do not wash the bag, the remaining dust can get into the machine.
If the draft was caused by not filling the dust canister, it is worth considering the following reason.
Next, let’s pay attention to the filters
When the vacuum cleaner draws poorly, check the filters. In any device there are only two of them: fine cleaning and exhaust. If the latter has never been changed, you need to put in a new one. Replacement is recommended every 50 hours of intensive use. The first filter should be changed periodically, cleaned regularly. You need to take it out, wash it with warm water, dry it and put it back. The filter of the device is located in front of the motor, more often on the back panel.
Check the brush, hose and other components
The appliance suction power can drop because its components, such as the hose or nozzle, are damaged. Let’s deal with the intake tube first. Inspect the place of connection with the body. It may not be inserted all the way or it may be loose. If it is blocked, clean it with a wire. It can make a noise when it works. Next we check the hose for damage. Whether the tube is the cause can be checked by disconnecting it and putting your hand to the outlet of the structure. Good intake force means that the hose is broken.
See how comfortable the nozzle is. It is often the cause of poor suction. In the other case we carry out a number of actions: brushes are cleaned of hair, threads. other debris; check the permeability inside and the brush roll. It should spin freely. If everything is OK, check the bearings. They can get stuck and obstruct the passage of air.
Low traction after the work is done indicates a malfunction in the motor.
If the cause is not corrected, then the motor or the motor will have to be repaired
Remove the protective housing to get at the heart of the machine. The fuse most often blows. You can check it with a multimeter, probing parts of the circuit. If it blows, install a new one with the same characteristics. A broken contact may be another reason. You can easily fix it with a blowtorch. To replace the motor brushes, you need to be very careful. Since a wrong connection can cause the opposite effect: the vacuum cleaner will blow out all the dust.
A serious cause is a broken winding on one of the coils. In this case we need to decide what is better: an expensive motor or a new device.
Motor failure is a problem that is more difficult to fix on your own. Lack of confidence indicates that it is better to contact qualified professionals.
The vacuum cleaner is heating and the suction power has dropped. what is the reason??
Why a vacuum cleaner heats up or why it doesn’t pull debris when cleaning? Devices often break due to improper use. Repair of equipment is sometimes costly. Buying a new one is even more expensive. To prevent breakdowns, you need to follow the recommendations for care. And if malfunctions have already appeared, we clarify the reasons and try to solve the problem ourselves.
How to figure out what’s causing the vacuum cleaner to heat up?
The most common causes are: dirty filters, full dust canisters, broken components, malfunctioning motor. How to understand what exactly affects the unit?
It is better to adhere to a certain sequence and use the method of elimination of unsuitable items:
- The vacuum cleaner, which will stop heating if you disconnect the hose and run it, the cause may be in the nozzle or in the tube itself.
- Next, check the inlet of the unit for additional obstructions. If everything is okay, go to the next point.
- Depending on the model of the vacuum cleaner, carefully remove the container where all the fine debris and dust falls: bag, container. Start the machine and watch it run.
- Another reason why the vacuum cleaner overheats and shuts down may be the filters. It is enough to clean them gently.
- The last item is a motor malfunction. In this case, the vacuum cleaner may overheat, which turns off by itself.
In most cases it is possible to make the repair yourself. This does not require deep knowledge. However, there are situations in which only a qualified technician can cope.
What is the reason for the drop in suction power?
The roots of the problem why the vacuum cleaner does not pull is the same as when it is heated. Occurs with units designed not only for dry cleaning but also for wet cleaning. A poor airflow is the first sign of malfunction.
So, if the vacuum cleaner does not suck dust, what to do? With the help of diagnostics, you need to understand the cause of the malfunction:
- The prerequisite is, unplug the appliance from the mains.
- Then we make an inspection.
- Check the mode. You might have accidentally snagged the lever or the settings are off.
- If this is not the cause, you need to disassemble the device. Let’s take the Samsung vacuum cleaner for example, not suctioning dust. Disconnect its components: brush, tube. Remove the housing and inspect the insides: dust canister, filters, motor, other parts.
If the cause of the failure is found and refers to the above items, you can begin to fix it.
Let’s start with the dust canister
Why is the vacuum cleaner not sucking up dust?? We often see the answer to this question when we remove the dust bag from the appliance. Older models do not have a special indicator that would show the degree of filling. So from time to time you need to check for yourself. Absorption power may decrease or even disappear when the dust canister is 70% full or more. It is therefore a good idea to change it.
When cleaning, pay attention to the material from which the garbage bag is made. If it is paper-based, it should be thrown out and replaced with a new one. If it is a cloth vacuum cleaner, give it a good shake and wash it without using any soapy detergents. When it is dry you can put it back. Such bags are reusable, however, it is necessary to follow the order of cleaning: if you do not wash the bag, the remaining dust can get into the unit.
If the draught decrease was caused by the dust collector not being full, it is worth considering the following reason.
Let’s look at the filters next
When the vacuum cleaner doesn’t pull well, check the filters. In any device there are only two: fine cleaning and exhaust. If the latter has never been changed, a new one must be installed. It is recommended to change it every 50 hours of intensive use. The first filter must be periodically replaced, cleaned regularly. To do this you need to take it out, rinse it with warm water, dry it and put it back in. The filter of the device is located in front of the motor, more often on the back panel.
Checking the brush, hose and other attachments
The suction power of the appliance may drop due to damage to accessories: the hose or nozzle. Let’s deal first with the suction pipe. We look at the joint with the body. It may not be inserted all the way in or may not fit perfectly. If there are clogs, clean with a wire. They can contribute to noise during operation. Next, check the hose for damage. Whether the pipe is the cause can be checked by disconnecting it and putting your hand to the outlet of the structure. Good suction power means the hose is broken.
Why Ticks Are So Hard To Kill
The sequence of steps to take when a vacuum cleaner overheats
If you find that the cleaner is overheating while running, perform the following simple sequence of actions:
- Unplug the flexible hose and turn on the cleaner if the noise changes and the heat is gone. the flexible hose or attachment is the cause. If the cleaner is still warm, there is something else going on.
- Carefully examine the inlet opening for obstacles in the path of the suction air, if the hole is not clogged, go to the dust collector if the presence of otoe.
- Remove the dust collector from the place of attachment and turn on the vacuum cleaner, if the air flow has normalized, and the motor has stopped heating. the cause was in the dust collector.
- Otherwise, the filters in the vacuum cleaner should be cleaned. This and the filter motor protection and filter cleaning air flow at the outlet of the vacuum cleaner.
- If all manipulations do not give a positive result, we get to the motor itself and determine the presence of faults.
The most complicated case is when the vacuum cleaner heats up and shuts down. It indicates the activation of a thermal relay that protects the machine from overheating. The situation has therefore reached a critical point and needs to be addressed and repaired as quickly as possible.
What to do if the vacuum cleaner began to hum heavily and stopped sucking
When a vacuum cleaner is humming but not pulling and the problem occurs for the first time, it can usually be repaired with your own hands. It is enough to clean the unit or make an elementary repair.
Clean or replace filters
If it is making a weird noise because the filters are clogged, clean or replace them. The algorithm depends on the design features of the device:
- Aquafilter. To clean, remove the container of dirty water and pour it down the drain. After that the filter is washed under the faucet with dish detergent, rinsed, wiped dry with a paper towel or cloth and placed back into the vacuum cleaner. It is also helpful to clean the inside of the water box compartment with a damp sponge. The water filter of the vacuum cleaner is accessible under the main cover of the device
- Cyclone filter. This element is usually made in the form of a cup or a small decanter, on the walls of which the compressed dust settles. By pressing a special button, the filter is removed from the unit as a whole, after which it remains to remove the lid and shake out the contents. After cleaning, it is also recommended that the cyclone be washed and dried for a couple of hours at room temperature before re-installation. The cyclone filter should be disassembled into its components for cleaning
- HEPA filter. The fine filtration elements are usually located in two places, behind the dustbin and at the back of the unit under the rear grill. When the vacuum cleaner is humming and not sucking properly, use the buttons or levers provided to open the housing and remove both HEPA filters. The reusable plastic elements are rinsed in warm water, dried and refitted, and the paper elements are simply replaced. If it is not possible to replace the HEPA filter, it can be gently blown dry with a hair dryer
Important! If your vacuum cleaner has disposable filters, change them more often. Even after dry cleaning, paper HEPA filters will not restore 100% performance.
Cleaning the hose, dustbin, and brush
When your vacuum cleaner is making a lot of noises and leaving behind a lot of debris, it is important to thoroughly clean the entire unit. The first thing to do is to free the dust canister from contaminants. Do it this way:
- open the special cover on the front panel of the unit;
- press the latch or peg holding the bag in place;
- Remove the product from the unit.
If the bag is disposable paper, it must be discarded immediately and replaced with a new one. Synthetic dust bags made of thick cloths are shaken out gently, being careful not to scatter dust on the floor, and then blown with a current of air on a balcony or in the entryway. Some bags can even be washed, the corresponding indication should be present in the instructions for the unit.
Empty vacuum cleaner bag without waiting for it to become full
Vacuum cleaner hose also needs maintenance. It is disconnected from the main structure, and then cleaned with a plumbing rope used for clogged drains. The hose can then be rinsed from the inside with running water and left in a warm room for several hours to dry completely.
If the robot vacuum cleaner began to hum strongly, or the manual model works worse, it makes sense to clean the brush. Threads, hair, hair and other debris gradually accumulate on its fluff. The suction power decreases, which increases the load on the motor and causes the vacuum cleaner to hum.
Especially the turbo brush of a vacuum cleaner gets clogged quickly when cleaning
- Use sharp scissors to carefully remove all hair and thread build-up;
- If you have floor/mop modes, pull out the bristles and also clean the debris;
- Immerse the brush in a basin of soapy water for 15 minutes;
- rinse the part thoroughly with a stiff sponge and rinse.
Wait until the brush is completely dry before putting it back on the vacuum cleaner.
Repair the motor
If cleaning the dustbin, hose and filters did not help, and still the vacuum cleaner’s motor hums, you can try to repair the motor. To do this:
- Using a screwdriver, remove the back cover of the unit;
- remove the motor;
- Remove the front part of the hood;
- unscrew impeller and wash it in hot water with soap and water;
- Pull out the armature and remove the bearings;
- In the case of mechanical damage, replace them with new similar ones;
- If there are no defects, wipe off old grease residue from the parts and apply a new coat of lithol or cyatime.
After that the bearings and the dried impeller carefully put in place without excessive pressure and assemble the motor part back.
When removing the vacuum cleaner motor, you need to remember or write down how the wires and fasteners were located
Attention! If the vacuum cleaner is humming even after cleaning the motor, replace the motor. The model must be found exactly the same, it is worth bearing in mind that the purchase can be expensive.
How to avoid problems
A few elementary rules must be observed when operating the vacuum cleaner. Namely:
- to service the dustbin in time, preferably after each cleaning;
- Clean the HEPA filter(s) regularly and not use it any longer than normal;
- Do not vacuum up excessively large debris or sharp objects;
- Do not use a liquid-collecting unit if it is intended for dry cleaning only;
- During a long cleaning period, turn off the vacuum cleaner from time to time and do not use it longer than allowed by the manual without interruption.
Conventional units are designed to pick up house dust or small debris. They cannot be used to collect construction dirt such as concrete or gypsum crumbs. It is also not recommended that you use the unit to suck up scattered flour. Fine substances in large volumes clog the filters almost instantly. In the best case, the vacuum cleaner after them hums, and in the worst case. it seriously breaks down and requires service repair.
If the vacuum cleaner is not sucking up dust
The causes of poor retraction of debris and dust can be the same as in the case of overheating. To identify the problem you should perform the following steps step by step:
- First of all, be sure to disconnect the machine from the network;
- Next is a general inspection of the unit;
- It is worth making sure that the chosen mode is correct. it is possible that the parameters are simply wrong;
- If all this does not help, you should disassemble the unit: you should disconnect the pipe and brushes, then remove the housing and inspect the insides (dust bag or container, filters, motor).
If a malfunction is discovered, go to the trouble-shooting effort.
Bag is overfilled
A common cause of poor vacuum cleaner draught may be an overfilled dust/dust bag: some older models do not have a level indicator, so check regularly to see how full the dust/dust bag is. When the dust canister is filled to 70% full the suction power may drop significantly or disappear altogether.
In the process of emptying it is necessary to examine the material of which the bag is made:
- The paper bags are disposable, so must only be replaced with a new one;
- Fabric bags can be washed in plain water and then returned to their place after they have dried.
If everything is okay with the dust collector, and the draft still does not appear, then you can proceed to the next step.
The filter is clogged
If the vacuum cleaner doesn’t suck, it could be because of the filters. Any model contains 2 filters, one used for fine filtration and the other for exhaust. If the exhaust filter has never been replaced, you should replace it now. it must be done every 50 operating hours. The fine filter should be cleaned regularly or changed: warm water can be used to wash it and then it should be dried well. The filters are usually located near the back of the unit.
Dirt in the hose or brush
A drop in suction power sometimes occurs due to a damaged hose or nozzle. The first thing to do is to carefully inspect the suction tube and look at its connection to the body. the tube may not be fully clamped or it may be loose. If there are clogs in the pipe, you need to clean them with a wire. Next, you need to check the hose for damage: to do this, you can disconnect it from the machine and put your hand to the inlet. If the draught is good, then the cause is in the hose.
Also check the attachment. sometimes it is the reason of bad work of the device. Clean the brushes from threads, hair and other debris, and check for permeability inside. Bearings should also be checked for proper operation, because the strength of the air flow depends on them.
Remove enclosure cover to gain access to the main part of the cleaner. Usually the fuse blows and the unit stops working. check it with a multimeter. If the fuse is faulty, pick up a similar one according to the parameters and install it in place. If the contact is broken, this could also be the cause of the fault. use a soldering iron to solder the damaged contact back in place. If there is a suspicion of malfunction of the motor brushes, you should work with extreme care. improper connection can cause the machine to start working the other way and just blow dust. If there is a winding breakage on the coil you must prepare to replace the unit or buy a new vacuum cleaner.
Each model has its weak points. At LG models during prolonged use begin to fail graphite brushes, and Samsung units sometimes fail in the insulation of the windings, which eventually leads to intercircuit.
Important! The faulty motor is almost impossible to repair by one’s own efforts, and its restoration will require the assistance of competent professionals.
The main causes of vacuum cleaner overheating
Often the heating of the body occurs due to debris filling the dust bag, broken components, as well as problems in the work of the motor. It remains to find out what caused the unsatisfactory work of the vacuum cleaner.
It is best to use the recommended troubleshooting sequence to identify the faulty assembly:
- If the case gets warm, you can disconnect the hose and try to run it again. if the engine case stops getting warm, it means that the cause is in the hose or the tube itself.
- Check the vacuum cleaner’s inlet next. foreign objects can get in there. After making sure that there are no obstacles, you can proceed to further actions.
- It is necessary to carefully remove the container for collecting garbage. it can be a container or a bag. After removing the vacuum cleaner, you can start it up and observe how it operates.
- Overheating can be caused by the filters. to do this, it is worth carefully cleaning them.
- If the above points are passed and the vacuum cleaner continues to perform poorly, motor failure remains, which can eventually lead to overheating and automatic shutdown.
Important! Often you can make repairs by yourself and without special knowledge, but sometimes you have to go to the experts.
Why the vacuum cleaner shuts off during operation: causes of rapid heating
Insufficient power supply for the machine to operate at full capacity
Reasons for loss of suction power are the same as for heating. There are expensive models and budget models. Poor oxygen intake. the first signal that there are malfunctions. A complete diagnosis will allow you to find out the true cause of the unit’s malfunction. Be sure to unplug the unit before doing this, then inspect and check the modes.
If that’s not the reason why the vacuum cleaner heats up and stops working well, then you need to disassemble the device. Take the old dust canister and detach the brush and tube from it. Then remove the housing and inspect the insides, such as the dust canister, filter, motor, and other parts.
Note! If the malfunction is not detected, you can begin to fix it.
Checking brushes, hose, and other components
Failure of brushes, hose and other components as one of the causes of a drop in suction power
Sometimes the reason for the lack of suction and why the vacuum cleaner overheats and shuts down is due to the convenience of the nozzle and its passability.
Please note! Often when the brush is clogged with threads, hair or hair and this prevents the debris from entering the unit. If that’s OK, it’s the bearings. If they are also good, then the cause is in the motor and motor system.
Why the Samsung vacuum cleaner began to collect dust and debris poorly, if the dust bag is in normal working order and clean? It is possible that the problem is a clogged filter. Checking the filters can shed light on the unit’s suction problems. There are two filters that need to be checked:
- The fine filter is located on the front of the motor and is usually mounted at the back of the housing. If it is clogged, the filter can simply be rinsed under running water and then dried. If the vacuum cleaner continues to malfunction, the filter must be replaced.
- The HEPA exhaust filter must be replaced after fifty hours of use, following the vacuum cleaner’s operating rules. This ensures that there are no problems with this type of filtration. So if you haven’t changed the filter type on your vacuum cleaner for a long time, you need to replace it.
What to do if the vacuum cleaner does not suck well?? How to fix it? | A drop in suction power causes the unit to leave debris, poor suction on carpets, quickly heats up and starts to go out, and soon may shut off altogether. Ask me, I am in touch!
Recovering the vacuum cleaner. 4 causes of poor suction
If the bag and filters are clean and the vacuum cleaner is working but not sucking up dust, it may be a problem with the hose or brush. This can be checked by disconnecting the hose. Then turn on the vacuum cleaner and put your hand to the inlet opening. If it feels like the draft has increased, then these parts need to be cleaned.
To do this, take them apart. The hose nozzle is viewed in the light, if there is debris stuck inside, it is removed with a match or a thin stick. Rinse the tubes under running water and dry. But more often the vacuum stops sucking because the brushes are clogged. This part comes in close contact with dust and debris, so it needs to be cleaned regularly.
The brushes get clogged with hair, threads, dust settles on them. It prevents the passage of air. Debris must be cleaned out, brush washed and dried. Sometimes it also happens that the rotating roller is jammed and blocks the opening in the brush. So it needs to be inspected regularly. And after each cleaning, remove the debris from it.
Additional Information! Nozzles on the hose in cheap vacuum cleaners are often clogged, they break bearings, which leads to reduced traction.
Vacuum cleaner automatics
Modern vacuum cleaners make automatics that protect the machine from damage. It can be triggered:
- for overheating
- for low pressure in the cavity directly behind the filter. Vacuum is created, which means that the pump is trying to pump, but the air is no longer passing through the filter.
- to excessive motor current consumption.
In all of these cases, the vacuum cleaner will stop. And on advanced models, a red warning light will illuminate.
And it’s very good. This means that the automation has protected your vacuum cleaner from malfunctioning.
First of all, do not be lazy and free from dust all the internal “closures”. whatever they may be. whether it’s a bag of dust, or internal cavities of various shapes.
So we have to clean it and wash some (or all) of it with water. Then everything is thoroughly dried. Then the vacuum cleaner is assembled and runs like a beast. like new.
The life of the filters, according to the recommendations of vacuum cleaner manufacturers, is usually 6 months, and can be reduced depending on the conditions of use. If there’s anything you don’t understand, feel free to email me!
Ways to fix the problem
Diagnostics only helps to find the cause of the malfunction of the vacuum cleaner. The next step is to fix the problem.
Overfilling the dust bag is the most common problem with poor suction. For any vacuum cleaner, do not fill the bag or the tank more than 80% full. With an increase in clogging the draught weakens or disappears completely.
High priced models have light indicators to indicate when the dust canister is full. A green light on the light bulb signals normal operation. When the light is red, the dust canister is full and needs to be cleaned. Cheap vacuum cleaners do not have this feature. It is necessary to check the dustbin after every cleaning.
The problem with a dirty dust canister is simple to solve. In a cyclone it is sufficient to simply throw the garbage out of the bin. The disposable paper bag only needs to be thrown away, and a new one put in its place. The dust canister must not be used a second time. After use and thorough shaking of the bag’s paper walls loosen. A re-installed disposable dust canister will be torn by a strong current of air, and the dust will be drawn inside the fan.
Reusable cloth dustbags are always just shaken out by the hostess. Cleaning method is good, but not effective. Large amounts of dust remain between the fibers of the cloth, blocking the free passage of air. Cloth bags are rinsed in clean water after several uses.
Dust collector may not be the culprit if the power regulator is screwed on tightly. Sometimes turning the wheel solves the problem of poor suction.
Fine dust filters
Contaminated dust canisters get noticed more often than fine filters, and in vain. One is in front of the fan. Cyclones usually have a foam padding inside a removable plastic bowl. The foam pad gets clogged with dust after each cleaning. The plate is carefully knocked out and rinsed in water. In addition, the plastic filter housing has a fine mesh grid on the back. It must always be washed.
A second fine filter is located on the exhaust side of the vacuum cleaner. It is usually made as a separate box with many cells. A filter prevents dust particles from flying out of the vacuum cleaner into the room. Clean clogged cells with a soft brush or rinse with clean water. Such procedures will succeed a couple of times. Replace the filter after 50 hours of use.
Vacuum cleaning attachments include bellows, telescopic handle, and wand attachments. During cleaning, an accidentally retracted large object jams in bends or transitions. The hose and telescopic handle can be cleaned with a long, burr-free stick or a soft, insulated wire. The air channel of the spray nozzle is usually curved. It is easier to clean it with something easy to bend: a wire, wire rope, flexible PVC rod.
Check the wheels on the brush after cleaning. They often have hair wrapped around them. If the roller is equipped with bearings, lubricate them.
Additionally check the connections of all components. Loose locks, cracks and other defects create air infiltration. A burst hose must be replaced at once. Fix the gap temporarily with the adapter sleeve. Cut the hose, put a piece of plastic tube inside, clamp the joints with clamps and wrap with tape.
If the reason for the weak traction is the electric part of the vacuum cleaner, the motor begins to work improperly. Extraneous noise, strong heating of the body, the speed decreases or “floats.
- Defective mains cable;
- Worn brushes, bearings;
- Contamination of the armature collector;
- Failure of start button or electronic unit.
The cause is difficult to find without a basic knowledge of electrical engineering. Electric motor must be completely removed, disassembled and tested with a multimeter. It is possible to change the brushes, bearings or the fuse on the electronic unit by yourself. Winding short circuit cannot be repaired. You will have to call for service or buy a new motor.
Causes of poor vacuum cleaner suction are many, and they all have a negative effect on the motor. At the first signs of a decrease in performance to slow down with the repair should not be delayed.
Worn out graphite brushes or blown fuse
If you have checked everything, but the vacuum cleaner is still not sucking and working poorly, you need to proceed to the examination of the motor. A common cause of breakdowns is the wear and tear of the graphite brushes. Their function is to transmit current to the motor. ), but they can only be changed by someone with a certain skill.
In addition to the condition of the brushes, check the operation of the fuse and replace it if necessary. If you have experience you can make a “check” of the motor circuit yourself with a multimeter and replace the fuse. Many fuses are equipped with a fusible link made of plastic, which fails when the appliance heats up regularly.
If you have no skills in handling the technique, give the electric appliance in the hands of a specialist service center.
The motor is probably the cause when the cleaner has a bad pull and begins to “warm up” heavily. Usually, it “warms up” gradually, but in this case it happens immediately after its connection to the socket. If it has a fuse, it will stop on its own if it overheats.
The worst case scenario is a motor stator breakage. If the fuse can be changed, nothing can be done if the stator ruptures. The coil winding cannot be repaired, so it is better to buy a new vacuum cleaner right away.
When the vacuum cleaner malfunctions, many problems can be fixed yourself, but if the motor is out of order. it is better to contact a professional technician.
