Bosch vacuum cleaners do-it-yourself repair

In detail: do-it-yourself Bosch vacuum cleaners repair from a real master for the site my.housecope.com.

Repair of vacuum cleaners, as well as other household appliances, is a common practice, since all appliances tend to break down. The most common cause of failure is the wear of parts and the destruction of mechanisms. However, a broken vacuum cleaner does not always mean that you need to buy a new one, since it is quite possible to repair such equipment with your own hands.

Vacuum cleaner is considered to be the most popular item of household appliances. Most housewives today can no longer imagine their lives without a vacuum cleaner, as it saves time and helps keep the house clean and tidy.

In most cases, the reason that the vacuum cleaner is out of order is the engine. Such a breakdown occurs with almost all makes and models of the device, regardless of the manufacturer. According to the characteristic features and features of the device, you can diagnose the problem and try to repair the vacuum cleaner with your own hands.

The first sign of engine malfunction is a hum and the appearance of a dust cloud during operation of the device.
Insufficient suction power or its complete absence indicates that the hose has failed. Another sign that the tightness of the hose is broken is the quiet operation of the device. In addition to the breakdown in the corrugation, the receiving brush can be damaged.
A low suction rate and a drop in operating speed may be due to bearing failure. Proof of the failure of these particular components is the periodic restoration of normal operation.
Excessive hum during proper operation indicates that the engine is out of order. In most cases, malfunctions in the motor directly affect the strength of the air suction power.

No matter what the cause of the malfunction, you need to know how to disassemble the vacuum cleaner in order to repair it yourself.

Repairing a vacuum cleaner with a wet cleaning function will be a little more difficult, since you will also have to work with a water pump. The main task of the pump is to supply water to the dust collector, for this reason the pump is installed at its inlet. When repairing a washing vacuum cleaner, attention must also be paid to disconnecting the pump.

When repairing a vacuum cleaner from the following companies: Hoover, Vitek, Samsung, Rowenta, it is recommended to check that the power cord is working properly. You can check the integrity of the cord with a multimeter. The reason for the failure of the cable most often lies in the active use of a vacuum cleaner, in which the cable is frayed, twisted and broken. If such a breakdown is confirmed, simply shorten the cable to the desired length or replace it.

Vacuum cleaners of the Dyson, Miele brand have a distinctive feature, which manifests itself in the frequent failure of the filter. A sign of dirty filters is low suction power.

It is very important to periodically clean and rinse not only the dust container, but also the filter. Timely care of the filtering system of the vacuum cleaner is the key to its long and high-quality work, which primarily depends on the health of the engine.

Today I got my hands on a wonderful example of German engineers - a Bosch vacuum cleaner. This mechanism did not last long without problems. But he got on my table, which means there are chances for a second life.
Using this vacuum cleaner as an example, I will tell you how to cure its “sore” (thank God, not fatal), which Bosch vacuum cleaners often suffer from

With the lid closed, check with your hand if there is a draft. There is no traction, which means we are moving on to extracting extra filters that can affect traction. After removing the internal filter in the debris compartment, we look into the hole where the engine is located. And here it is, our problem: the impeller of the engine is clogged with debris. Most likely, this happens due to an oversight of the owners. The bag was not inserted tightly, the filter was not cleaned or changed for a long time, etc.So, patient, let's proceed immediately to the autopsy.First, let's remove the top cover. If this is not done, she will interfere with us. Carefully pry the cover fasteners with a flat screwdriver. Image - Bosch vacuum cleaners do-it-yourself repair

Now we are looking for screws to open the case. Two of them are hidden under the sealing gum of the cover we removed. One is under the power button (it also needs to be removed, with the same flat screwdriver, pressing the fasteners on the side). Now, with a Torx15 nozzle, we unscrew the self-tapping screws we found.

Armed with something flat, we open the upper and lower half of the case. Inside, we are greeted by multi-colored wires and a new cover, under which the patient's heart, the engine, is already waiting for us.

But first we need to pull out the speed controller (a small scarf on colored wires). To remove it, push the speed control shaft up and to the left. Now getting the regulator itself out of the grooves is not difficult.
We unscrew the only self-tapping screw that separates us from the target and easily separate the cover of the motor box up, not forgetting to pry it off in front with a screwdriver.

Our matryoshka has opened! Inside, on the "cabbage leaves" of sound insulation, our motor is hidden. And to the right of it is the control unit. It is on him through the network cable, and then electrons run through the cable layer in order to rotate the ill-fated impeller.

Something I digress from the motor. We remove the power terminal and remove the motor. A pile of hair and dust - that's what appears before our clear eyes. All this "wealth" is stuck in the holes of the impeller, the task of which is to draw in air during rotation.

The second vacuum cleaner, borrowed from good neighbors, will help us deal with this problem. “We clean, we clean the chimney sweep ...”, well, you understand. Chimney sweep, i.e. engine is clean. Now we need to clean other nooks and crannies. I'm talking about the case itself and sound insulation, which not only makes our vacuum cleaner quieter and more expensive, but also collects dirt no worse than a real janitor. Everything is clean, so it's time to "sew up" the patient, i.e. gather. Don't forget the tools inside.
The assembly process of the vacuum cleaner is carried out in the reverse order to the disassembly process.

And so he sang and hummed, drawing in air, speaking in his own language, “Thank you, Friend!”

Regardless of the type of vacuum cleaner, the engine is called the heart. Television programs love to depict the creation of a vacuum, in our opinion what has been said is an inept manipulation of words. The motor draws in air with a blade, the filter protects the moving parts from dust. Each bearing is provided with an insert for this purpose. The engine is deprived of protection from vacuum ... Do-it-yourself vacuum cleaner repair is advisable when the heart of the device is functioning properly, there is a need to replace, modify the brushes, lubricate the bearings. It's lovely that the devices are similar from the inside, like two peas in a pod. The mechanical part, the device of the dust collection tank, filters, brushes, hoses, housings differ. Accessories are an essential part of the device. The device of the vacuum cleaner, the fundamental idea remains the same!The heart of the vacuum cleaner is rightly called the motor, traditionally a collector. Briefly consider the design of an indispensable product, create a clear idea. In an asynchronous motor, a rotating field is created by the correct distribution of phases by the windings, the winding collector commutates in series. There are unpopular exceptions. The direction of movement is determined by the switching direction:

The current flows, the fields work for attraction.

Current flows, fields repel.

As for the question why the rotor rotates in this direction, which is not opposite when the windings are connected unidirectionally, the answer is revealed by the mutual arrangement of the brushes and stator coils, the structure of the collector. The number of coils wound on the armature is equal to the number of contact pads of the shaft. The brushes feed only one winding at a time. Then the shaft scrolls some angular distance, the next coil is powered. One revolution passes, the cycle begins again.Imagine a stator pole (so far only one - not two) at the bottom. Suppose, at the initial moment of time, the brushes are set in such a way that the armature pole is fed to the left of the construction axis. Then, due to repulsion, the shaft begins to describe the hour hand. The axis passes the angular distance, the current begins to flow around the next winding, which has managed to take the place of the previous one. This happens as long as there is current. And there is no difference, constant or variable. The collector motor will work driven by the direction of the field. The rotation speed is not determined by the frequency - the design of the mechanical part, the magnitude of the voltage.Now if the fields are attracted, the rotation will start counter-clockwise. By the time the stator and rotor poles are opposite each other, the power will be transferred to the next coil, which will begin to create the desired force. The cycle is circular. Now coils. Collector motors are equipped with a pair of stator windings for direct current, because the alternating current encounters too much resistance from the inductances. This is why some commutator motors are made with separate stator terminals. Allows you to use one instead of two windings. It is clear that the load capacity drops significantly. But losses are reduced.In a vacuum cleaner on the motor stator, we notice two diametrically opposite windings that help each other. Mutually beneficial coexistence is ensured by the right direction of inclusion (wrote above). Reversible motors have a special power relay that switches the poles in the proper order. For comparison, in an asynchronous motor, such a relay distributes the voltage phases in a different way. It turns out a reverse. The collector motor does not require a starting winding and a capacitor (one phase), which are trying to imitate a second winding. Simply put, the efficiency of three-phase asynchronous motors is higher. The brainchild of Nikola Tesla and Dolivo-Dobrovolsky are used by industrial equipment, in the 90s they were replaced by collectors from household appliances (vacuum cleaners were traditionally supplied with graphite brushes before perestroika).Two brushes are used to transfer current to the armature. The difference is leveled, where is plus, where is minus, the direction is provided by correct switching.Is it possible, by changing the order of connecting the brushes, to make the motor rotate in the opposite direction. The field polarity is reversed. This technique is used to obtain a reverse with a constant voltage. When performing self-repair of vacuum cleaners, remember the correct position of the contacts.A tangential fan is hidden behind the coarse and fine air filters. The air enters in the center, is ejected to the periphery, moving forward, enters the room through a HEPA filter that traps particles with a size of a micron (micrometers). The blade is covered with a lid, the part is made in the form of curved aluminum partitions between two metal planes. There are closed channels. The motor is encased in a plastic casing (traditionally white) in which the outlet flow path is cut.It is interesting! Due to the presence of a tangential fan, the efficiency of the vacuum cleaner barely reaches 20-30%. With a power consumption of 1600 watts, the suction will be 350 watts.Brushes are mounted in mines, it is useful for beginners to know: this is a typical pencil graphite (carbon, coal). You can, if necessary, sharpen parts, adjust as needed so that they become in place.If the area of contact with the collector is small, it's not scary, the brushes will gradually run in. The tips are slightly worn in a semicircle inward. Each brush is pressed by a spring through which current passes, the measure will ensure a long service life for products. Carbon will work until it is worn to the ground. However, the copper collector must be clean. Wipe with your favorite product if necessary, remove the oxide film to a copper sheen.The shaft is attached to the stator with two bearings. Different sizes to make it easier to disassemble the vacuum cleaner motor. The front bearing is large, the rear is small. The shaft is carefully knocked out of the stator by suitable means (pneumatic puller), moderate heating helps. The bearings are equipped with anthers. Although the vacuum cleaner creates a vacuum, dirt also penetrates there. The anthers are carefully removed with a screwdriver, if necessary, lubricate the parts. Suitable: HADO composition, Litol - 24, EP - 2. The lubricant is put inside, the anther is put in place.Do-it-yourself vacuum cleaner repair begins by removing the case. Each case has its own methods. Filters are removed to block access to the engine. The electrical installation is disconnected (the vacuum cleaner is unplugged), the plastic motor housing is unscrewed from the frame. The motor should be removed from the casing, after which the fan is removed. The nut has a left-hand thread, turn carefully. Following the fan is a collector-cover, under which the electrical part is hidden. The further course of operations is clear from the previously read up to the extraction of the rotor.If necessary, the bearings are trimmed with a threaded puller or a hydraulic press. Auxiliary devices are used. Small balls with a diameter passing inside the bearings. It is recommended to flatten on one side so that they do not roll. Reverse installation is carried out in a similar way. If you hold the anchor by the bearing in your hand, the rotation should be fast, silent, confident. When lubricating, the outer anther is removed, take the trouble to put new spare parts on the same side.

Regardless of the manufacturers and types of vacuum cleaner, the main difference lies in the quality, power and design.

The most important thing in a vacuum cleaner is an electric motor that creates a vacuum and, as a result, sucks dust and various particles through special filters through which only air passes.
In different types of such devices, these filters are different, and flasks and just bags and cyclonic vacuum cleaners.

But it is the engine and, occasionally, the electronic power (speed) control circuit that requires the most attention in this whole device.

Do-it-yourself engine repair is not difficult to carry out if the breakdown is simple and the engine is still running but the engine is heavy (when turned off) or the engine starts to rumble or hum strongly, sometimes the vacuum cleaner gets very hot in a short period of time.

The heart of the vacuum cleaner, as we have already figured out, is the engine and, as a rule, the collector.
What is such an engine?
The engine is housed in a housing where the fan impeller blades are hidden. It is of a tangential type, where air is drawn in in the center and exits through the periphery and through the rear filter is already out.
The brushes in the engine are placed in special mines made of brass, as a rule, this is ordinary carbon in the form of graphite. Over time, the brushes are rubbed against the collector roller, their middle is ground off and they become slightly semicircular, due to which the contact area with the collector areas increases. The brushes in their mines are pressed by springs, creating the necessary pressure of graphite, in the process of robots, to the collector. The brush will work until that time until it is worn out and the spring cannot properly contact the graphite to the commutator.
It is necessary to monitor the cleanliness of the collector shaft itself, clean it from carbon deposits if necessary, and remove the oxide layer to a copper sheen.

The shaft is attached to the stator on two bearings of different sizes, as a rule, this is done in order to make it easier to disassemble it. The front is usually large, and the rear is smaller.

The shaft is carefully knocked out of the stator using any suitable tool. Then we look at the course of the bearings, because of the dusty robots they become clogged despite the presence of anthers. If necessary, the anthers are carefully removed with a thin screwdriver or an awl, washed with a WD-pattern, after which the balls must be lubricated, for example, with Litol-24 or EP-2 type grease, after which the anther is put in place and snaps into its grooves in the bearing itself.

To start some kind of repair or maintenance of the vacuum cleaner, you need to remove the case. Each model has its own methods.
First of all, all filters that make it difficult to access the motor are removed, the case screws are unscrewed, including hidden ones (under the buttons, for example). Having unscrewed all the screws, you need to carefully try to disassemble the case, if this fails, take a closer look at where else there may be latches or additional screws, if you do not pay attention to this, you can break the case.

Then the entire electrical installation is disconnected, as a rule, the connections are made on the connectors.
The plastic housing of the motor is unscrewed from the frame, after which the motor is removed from its plastic housing.
In some models, it is simpler and the motor itself is fixed in the vacuum cleaner body in special rubber grooves-seals or is screwed tightly to the general body of the vacuum cleaner.

To disassemble the engine and remove the fan impeller First of all, we will remove the front part of the casing (above the impeller). We take a thin metal object, you can use a screwdriver and carefully bend it from the side of the casing so that the screwdriver goes a little into the middle, then with a gentle movement we push out the upper part of the casing, as a result of which the entire impeller becomes available to us.

The nut on the impeller usually has a left-hand thread (but there are exceptions) We try to unscrew it while holding the impeller with your hand, if it scrolls and you cannot unscrew the nut in this way, there is one great way
So..we take a good stranded wire with a cross section of more than 1.5 mm in dense rubber insulation (to prevent slipping). We push such a wiring and wrap the collector shaft 2-3 times, turn to turn and stretch in different directions, thereby fixing the shaft motionless.

It is most convenient to do this together, one person fixes the collector using the ends of the wire stretched to the sides, and the second unscrews the nut on the fan disk.
The method is very convenient and safe for fixing the anchor. In the same way, when reassembling, tighten the nut.

After removing the fan impeller, unscrew the housing screws, by this time the brushes should already be removed.

Then we carefully pull out the anchor, if necessary, twisting the upper part a little.

If necessary, the bearings are removed using an available tool or special threaded pullers. In especially severe cases, sometimes the bearing “sticks” tightly with the bushing, a special hydraulic press is used to remove the bearings.

bearings
brushes
fuse
network wire
no contact in the switch
motor windings, breakage or burnout of the winding (stator or rotor)
capacitor failure
failure of the electronic circuit of the power regulator

Loss of power and suction.
The most common cause is either clogged filters or bearing failure.
The filters must be cleaned and the operation checked again, also the operation (draft) of the vacuum cleaner without filters should be checked, as it happens that the usual cleaning of the filter does not help and it already needs to be replaced.
If the traction without filters does not give the same working traction, you will have to disassemble the vacuum cleaner, the impeller on it should easily turn with your finger without much effort. Additionally, we remove and inspect the brushes and clean the collector from soot, using sandpaper or a piece of ordinary cloth.

In some cases, the tightness of the hose is broken, this can be both a violation of the integrity of the hose itself and the connecting pipes at the ends of the hose, the hose simply slips out of them a little.

The vacuum cleaner does not turn on.
If everything is fine with the voltage at the outlet, we disassemble the vacuum cleaner and first of all inspect the fuse and power cord, especially at the very end of the cord on the winding drum at the soldering points.
If there is a tester, we call for a contact.
The power button could break, or the contact is simply broken in it, it sometimes gets clogged, again with the help of a tester we make sure that the button is working.
If all the elements were rung by the tester and the voltage comes to the motor brushes without any problems, and the brushes themselves are not erased, then most likely you will have an expensive engine repair or simply replacing it, since in most cases it is more expedient to install a new motor than to repair a tired old one by rewinding.

If the vacuum cleaner worked for a long time and does not turn on then it is quite possible that the protective thermal relay on the engine itself has worked as a result of overheating - in this case, there is nothing to repair, it will be enough to leave the vacuum cleaner to cool the engine.

Vacuum cleaner motor speed not adjustable.
The most common cause of such a malfunction is a breakdown of the triac, in which the voltage through it is not regulated, but freely passes through it without any control. Possible failure of this element and possibly loss of contact on one of the legs of this element on the board.
By slightly pressing down on the speed control knob, you can make sure that the regulator itself is in good condition or that the contact may be broken in it and the regulator slider will not contact its site.

Vacuum cleaner emits odor and hot air.
First of all, you need to make sure that the suction inlet is not clogged, inspect the hose, check the retraction force at the inlet and whether the sound of the engine changes when the inlet is plugged with the palm of your hand. In the case of satisfactory operation on the part of the suction system, we can assume a malfunction of the engine, and most likely the brushes.

The vacuum cleaner hums and rumbles - the reason for this action is the engine, and in particular its bearings. Most likely they need additional lubrication or, if there is a large shaft around their axis, they need to be replaced with new ones.

The cord does not tighten when pressing the button or constantly tightens during operation - violation of the winding drum, the spring may have burst, weakened or vice versa is too tight.
We inspect the pressure roller of the button and, if necessary, by removing the drum, we wind or unwind the wire on the drum - changing the tension of the drum itself to the one we need.

As a rule, it is not complicated and in most models it is quite standard.

There is an opinion that vacuum cleaners for dry cleaning break less often. We immediately hasten to reassure the owners of Bosch washing vacuum cleaners: in the case of this brand, this pattern is not traced. Perhaps lesser-known manufacturers save on development and parts for their washing vacuum cleaners (in connection with which there are more frequent cases of calls to the SC), but Bosch does not do this.

Repair of vacuum cleaners Bosch, Siemens in the service center depends on the degree of damage and can be simple, medium or complex. The type of repair, its feasibility, as well as the cost of further work are identified during the diagnostic process.

Simple repair: includes repairing (or replacing) the housing, rewinding (or replacing) the cord, replacing hoses and nozzles, and clearing blockages in the water supply system.

Average: this category includes the repair of controls, the electronic control unit, the restoration of the functions of the cord winding mechanism.

Difficult: this category includes the replacement of the engine or its components.

The main types of breakdowns of vacuum cleaners

Overheat. Even the highest quality household vacuum cleaner is designed to clean dust and debris only in small areas (in apartments, private houses, office premises), and therefore cannot work longer than 30-40 minutes a day. As a rule, it is the excessive cleanliness and scrupulousness of the hostess (or owner) that leads to overheating of this household device. Maintenance in such cases is reduced to replacing the motor winding or replacing the entire motor.

Blockage. The power of modern vacuum cleaners can exceed 2000 W, while the rotation speed of its turbine varies in the range of 18,000 - 22,000 revolutions. Just imagine what kind of load falls on the elements of this household device. Even in the case of suction of ordinary house dust, blockages are not uncommon. What to say about construction debris or cement dust.

Moisture ingress into the motor. The turbine of the vacuum cleaner is made of metal, and therefore oxidation or rust resulting from moisture ingress can quickly disable a household appliance. In addition, moisture that gets inside the turbine can lead to the accumulation of dust on its blades, thereby worsening the operation of the device. To delay the repair of the vacuum cleaner in the service center for as long as possible, try to avoid getting moisture into it.

Tips for care and use

The main parts of the design are the engine and the rotor. Usually, high power of electric motors is achieved by increasing the frequency of its revolutions. As a rule, the mass of such motors increases in proportion to the power, but this is unacceptable for household vacuum cleaners, and therefore their electric motors are made lighter by a significant increase in the current density in the stator and rotor windings.This approach leads to an increase in the heat dissipated by the engine, and therefore it is extremely important to provide it with proper cooling.
When cleaning, try avoid neighborhood vacuum cleaner with battery radiator, gas stove and any other devices that emit heat. In addition, it is important monitor the level filling the bag and the degree of contamination of the filter, since the engine is cooled by the intake air flow and excess dust can interfere with this process.

DIY repair

In some cases (for example, when bearings are worn and jammed), repairs can be made on their own. To do this, you need to get to the engine of the device, gradually removing all its plastic elements, and replace the worn part (in some cases, wear of graphite brushes may occur). If any elements of the body refuse to be removed, do not try to use force. All plastic panels should be easy to dismantle. If this does not happen, then you are violating the disassembly order. If you can’t find the source of the breakdown and fix it yourself, contact a specialized Bosch / Siemens service center

Good afternoon. I have a problem, my vacuum cleaner broke down and now I don’t know how to clean the apartment. Please tell me how to properly disassemble a bosch vacuum cleaner, because I have never done this before

Good day. I can help you with this problem. The bosch vacuum cleaner is very simple and quick to disassemble because it is the simplest type of vacuum cleaner. It has a special button for removing the cover. Then you need to unscrew the screws to completely disassemble the vacuum cleaner

... to disassemble such a vacuum cleaner, you need to take a shurik or ...

... models of vacuum cleaners, both for construction work and for the home KARCHER ...

Easier than simple, remove the cover with the help of a button, pull out a bag of garbage and with a screwdriver you already unscrew the screws, not the screws. It is divided into two parts, remove the top and voila, all the details are in plain sight.

My GL-30 also broke, I unscrewed the screws, but it does not open at the bottom,

It looks like the upper part is attached to the latch. I'm afraid to pull hard, it might break

I didn’t see the diagrams about disassembling the Bosch Max vacuum cleaner, I advise you to try to disassemble it yourself, you only need to unscrew a few bolts and remove the cover.

Maybe it will come in handy for someone: when disassembling the body of a Bosch BSGL3 series vacuum cleaner, after unscrewing three screws, you need to knock off the two lower twisters with wheels, and under one there is a specific latch, and under the other there is a hole, in the depth of which there is also a light latch. After that, the upper part of the housing is freely removed.

To disassemble the Bosch Ergomaxx, you need to unscrew four self-tapping screws. From the back, where the handle is, pick off the rubber bump stop, under it on both sides of the latches, press on them and remove the casing. Everything else is no problem.

I want to get into a renovation school, or at least a designer of a children's room, how much will it all cost?

It depends on what kind of job you got.If you are a builder, then this is one type of overalls, if you are an electrician, then another, and if you are a health worker or a kitchen worker, then the third, radically different. If, nevertheless, your type of activity is associated with a working specialty, then something like this suit may suit you: This is for winter. He is universal.

On average, a vacuum cleaner can last from 8 to 12 years (except for Samsung vacuum cleaners with a cyclone filter). This period will always depend on its quality, maintenance and frequency of use. If problems arise with this household appliance, a quality repair can extend its service life. Bosch vacuum cleaners are durable and reliable, but there comes a time when they also need to be repaired.

After all, it is known that the motor requires new brushes, and due to improper use, the hose or nozzle can get cracked. But, this is not all breakdowns. And the point here is not only to repair the device, but to provide for replacement original spare parts that are produced at the native factory.

Among the problems of Bosch vacuum cleaners, which are included in the cleaning equipment group (and these are even small vacuum cleaners for the home), the most basic are:

extraneous noise during operation;
extraneous smells of burning during the operation of the device;
no response to activation. Here quite often lies a large-scale problem and a preliminary inspection of components and assemblies is needed.

If the Bosch vacuum cleaner suddenly began to suck up dust poorly (a common problem with Electrolux cordless vacuum cleaners), the first thing to do is to check the power regulator, which can be in the minimum position. Then you need to check the dust collector, which may be full. Often dust collectors can be damaged and it is better to replace them with new ones.

The brush, nozzle and hose can also become clogged due to especially large objects getting stuck in them. A universal turbo brush can be bought for 400 rubles, but you can buy an original Bosch brush for 2500 rubles. The hose costs about the same (for Samsung vacuum cleaners with an aqua filter, a little more).

The tightness of the suction system is very important. If cracks are found, they can be treated independently using sealants, otherwise replace the damaged parts with new ones. Often the hose cracks, and in this case, of course, you also have to buy a new one.

When there is an extraneous smell, and hot air comes out of the Bosch vacuum cleaner, again you will have to check the hose and dust collectors. Clogged dust collectors (a common problem with Electrolux vacuum cleaners), hoses and brushes often cause the engine to overheat and fail. You also have to change or clean Hepa filters from time to time, on which the durability of the motor depends.

After all, it is these filters that protect the vacuum cleaner motor from dust. Replacing the filter with a new one is quite simple and does not require a qualified specialist.

Original Hepa filters can be bought in company stores. They have a high degree of filtration. The Hepa filter is made of fibrous materials, so even the smallest dust particles get stuck in it without getting into the motor. High-quality original Hepa filters on the market can be bought at a price of 300 to 800 rubles (for Zelmer washing vacuum cleaners for 1000 - 1200).

If the vacuum cleaner does not start, the problem may be hidden in the damage to the cord. Often you only need to change the motor brushes that have worn out. Each brush has its own working resource and wears out over time, ceasing to supply current to the motor coil.

And if you understand a little about technology, you can replace these parts yourself.It is only necessary to choose original spare parts, then the brushes will work for a long time. Bosch vacuum cleaner brushes are inexpensive, the kit costs about 50 rubles.

Sometimes you have to repair or completely change the engine (this is especially true for upright vacuum cleaners). For Bosch vacuum cleaners, it will cost about 1000 - 4000 rubles. To ensure the engine has a long life, you need to monitor the condition of the hepa filter, which protects the engine from dust and other debris.

In addition, it is often necessary to lubricate or replace the bearings of the vacuum cleaner, flush the nozzles, replace the elements of the electrical circuit, motor control modules, switches, and plugs. And again you have to buy original spare parts for these purposes.

Bosch upright vacuum cleaners have a longer service life. But in order for the engine to work for a long time and reliably, it is necessary to periodically clean the filters, dust collectors, hose, or carry out a complete preventive cleaning of the elements. Also, nozzles and a turbo brush (especially for Makita vacuum cleaners) need cleaning.

It is best to buy all the necessary spare parts, including seemingly the most elementary ones, such as nozzles, a dust collector, a hose, a brush, only in a specialized Bosch store.

The fact is that the duration of the operation of vacuum cleaners will depend on their quality. But still non-original options are allowed. If it is necessary to change the motor completely, or its individual elements, it is preferable to buy only original spare parts.

It is worth remembering that most of the maintenance work, as well as the repair of Bosch vacuum cleaners, can be done by yourself (except for the repair of iClebo Arte vacuum cleaner robots). Cleaning or changing filters, dust collectors, nozzles, repairing or installing a new hose will not be difficult for any ordinary user. The old brush is easily replaced with a new one.

But the motor brushes and the motor itself require a more qualified approach, but there should not be any difficulties here either. Often there is a need to carry out more complex repairs, which require qualified specialists (relevant for Karcher washing vacuum cleaners).
