All breakdowns associated with a vacuum cleaner most often relate to the operation of the engine. Regardless of the model, the motor has a blade and helps to draw in air. The filter protects the moving parts from dust, but the engine simply has no protection against vacuum. When a vacuum cleaner breaks down, many people think about fixing it on their own. This is advisable in situations where the engine is working properly, but there are problems with brushes and bearings.The motors inside the vacuum cleaner are similar to each other. Vacuum cleaners differ only in mechanical parts, devices for collecting dust, filters, hoses and housing, and the design of the brushes.
To repair, you need to disassemble
Possible problems in the operation of the vacuum cleaner, which you can fix yourself, are described in detail below in this article. But the repair begins with the fact that the vacuum cleaner should be disassembled. Initially, the case is removed: depending on the models, the methods will differ, but they are clear and simple. When the case is open, it is necessary to remove the filters that will block access to the engine.
The vacuum cleaner must be unplugged from the socket! Disconnect the electrical installation and unscrew the motor from the frame. The motor is then removed from the casing, then the fan is removed. The nut usually has a left-hand thread. The collector-cover will be located behind the fan, and under it is the electrical part.
Possible typical breakdowns:
- Brushes and bearings;
Sometimes a vacuum cleaner has two motors. The second is located directly on the brush, due to which the villi move. Moving air does the same job in turbo models. When cleaning the brushes, which have an additional motor, do not press hard, because the weight of the device itself is already decent.
Important! The washing vacuum cleaner, in addition to all the components described above, also has a pump that supplies water to the hose. Very often, such vacuum cleaners, due to their high cost, have a self-diagnosis system, which suggests that there is a problem. You can read about the possibility of their self-elimination in the instructions for the household appliance.
When the vacuum cleaner does not work when turned on
In such a situation, the malfunction is related to the availability of electrical power. The outlet, plug, or power cord may be defective. In rare cases, this situation indicates engine failure. To understand what caused the malfunction, it is necessary to check all the elements of the circuit: inspect them well. Wire damage can most often be seen near a plug or at the entrance to a vacuum cleaner.
If the engine is out of order, then it will be quite difficult to repair the device with your own hands. Often, even in service centers, they cannot help solve problems, and if they offer a possible repair, then it’s worth working like buying a new vacuum cleaner.
Not every housewife will be able to disassemble the vacuum cleaner even using the detailed instructions written in this article. But the husband or father, the eldest son will be able to cope with the task. Having disassembled the case and component parts of the device, you can judge how serious the problem is and whether it is possible to fix it yourself or you will have to contact a service center.
Please help me with advice: how to disassemble a Bosch BSG 72225 vacuum cleaner? Two obvious screws were found, but there are two more secret ones - how to find them? You need to get to the winding mechanism of the power cord, it is jammed - and it is at the very bottom.

On average, a vacuum cleaner can last from 8 to 12 years (with the exception of Samsung vacuum cleaners with a cyclone filter). This period will always depend on its quality, service and frequency of use. If problems arise with this household appliance, high-quality repairs can extend its service life. Bosch vacuum cleaners are durable and reliable, but the time comes and 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 original spare parts for replacement, which are produced at the home plant.
Among the problems of Bosch vacuum cleaners, which are included in the group of cleaning equipment (and these are even small vacuum cleaners for the home), the most basic are:
extraneous noise during operation;
foreign smells of burning during the operation of the device;
lack of reaction to inclusion. There is quite often a large-scale problem here and a preliminary inspection of components and assemblies is needed.
If a Bosch vacuum cleaner suddenly began to suck up dust poorly (a common problem with Electrolux cordless vacuum cleaners), the first thing to do is check the power regulator, which may be in the minimum position. Then you need to check the dust collector, which may be overfilled. Dust bags can often get damaged and it is better to replace them with new ones.
The brush, nozzle and hose can also become clogged if large objects are caught in them. A universal turbo brush can be purchased for 400 rubles, but you can purchase an original Bosch brush for 2500 rubles. The hose costs about the same (slightly more expensive for Samsung vacuum cleaners with an aquafilter).
The tightness of the suction system is very important. If cracks are found, you can treat them yourself with sealants, otherwise replace the damaged parts with new ones. The hose often cracks, and in this case, of course, you also have to buy a new one.
When there is a foreign smell, and hot air comes from 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 motor 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 technician.
Original Hepa filters can be bought in company stores. They have a high filtration rate. 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 damaged cord. Often you only need to replace the engine brushes that are worn out. Each brush has its own working life and wears out over time, ceasing to supply current to the motor coil.
And if you know a little about the technique, you can replace these parts yourself. You only need 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 carry out repairs or completely change the engine (this is especially true for vertical vacuum cleaners). For Bosch vacuum cleaners, it will cost about 1,000 - 4,000 rubles. To provide the engine with a long service life, you need to monitor the condition of the hepa filter, which protects the engine from dust and other debris.
In addition, lubrication or replacement of vacuum cleaner bearings, flushing of nozzles, replacement of electrical circuit elements, motor control modules, switches, plugs are often required. And again you will 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, periodically it is necessary to clean filters, dust collectors, a hose, or to carry out a complete preventive cleaning of the elements. Also, nozzles and a turbo brush need cleaning (especially for Makita vacuum cleaners).
It is best to buy all the necessary spare parts, including such seemingly most elementary ones as nozzles, dust collector, hose, brush, only in a specialized Bosch store.
The fact is that the duration of the vacuum cleaners will depend on their quality. But non-original options are still 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 can be easily replaced with a new one.
But the engine brushes and the engine itself require a more qualified approach, but there should be no difficulties here either. Often there is a need to carry out more complex repairs that require qualified specialists (relevant for Karcher washing vacuum cleaners).
In electric vacuum cleaners and electric polishers are used collector motors requiring special care during operation. When inspecting the vacuum cleaner, it is necessary to pay attention to the condition and degree of sparking of the carbon brushes, the condition of the collector plates, the sealing of the body, the serviceability of the locks, the hose and the dust filter, the tightness of the connections of the hose and extension pipes with the vacuum cleaner body.
Collector arcing (switching class) should be equal to two (slight sparking under most of the brush). The condition of the collector and brushes is characterized by the presence of blackening marks on the collector, which can be easily removed by wiping the surface with alcohol or special synthetic detergent, as well as carbon deposits on the brushes.
For troubleshooting in many cases, minor or medium repairs are sufficient. Minor repairs are characterized by the elimination of simple defects, tightening of loose fasteners, and adjustment of easily accessible assembly units. Medium repair is associated with the replacement of failed assembly units, their adjustment. In other cases, overhaul is performed: complete disassembly of the unit, testing and adjustment.
Vacuum cleaners and floor polishers refurbished at the customer's home are checked visually. Inspect the housing, air intake unit, electric motor, drive belt, connecting cord and soldering points. Then the repaired device is connected to the mains and its operation is checked.
Typical malfunctions vacuum cleaners and ways to eliminate them are given in table. 4.6, and similar information about floor polishers - in table. 4.7.
A large number of electrical appliances are used in any living space. You can easily repair vacuum cleaners with your own hands, just having a standard set of tools with you.
Regardless of the model or design of vacuum cleaners, most often any problems with this technique are associated with engine malfunctions. If the device is humming, dusty or makes intermittent sounds during operation, this is the engine junk. At the same time, if the vacuum cleaner does not suck in debris or the pressure is insufficient for normal operation, then most likely this is a hose malfunction.
Troubleshooting :
When the speed and suction power drop, the most common cause is bearing failure. In this case, you can also observe a periodic restoration of the functionality of the device, that is, a temporary drop in its efficiency does not affect continuous operation;
If the vacuum cleaner hums, but at the same time it normally sucks up debris and dust, then the cause is a malfunction of the engine. Basically, all failures associated with weakening of power relate to the motor device;
If there are no loud sounds during operation, but the vacuum cleaner does not suck in the usual amount of debris, then the hose is not tight. We draw your attention to the fact that the problem may lie both in the violation of the integrity of the corrugation, and in the breakdown of the receiving brush.
You can disassemble a standard Electrolux, Philips, Thomas or any other vacuum cleaner for repair using the following instructions:
At the same time, maintenance of washing vacuum cleaners (Karcher - Karcher, Zelmer - Zelmer, Bork - Bork and others) is significantly complicated by the presence of a water pump. It supplies water to the dust collector and is installed on its course, therefore, in addition to the steps described above, you will also need to unscrew it.

Before disassembling models of vacuum cleaners Hoover, Vitek, Samsung, Rowenta (Roventa) and others for parts in order to get to the engine and repair it, you need to check the power cable. Due to the fact that the cord is constantly in an active state (it is pulled from room to room, is under constant tension), it quickly wears out. To check its performance, you can use the most common multimeter. After finding the place of fiber fracture, replace the faulty section or cut the cable to the required length.
If the pressure in a Dyson or Miele vacuum cleaner starts to drop noticeably during operation, the first thing to do is to check the filters. They get dirty after each use of this cleaning technique, but not every housewife cleans them as often and as thoroughly as dust collectors. Once every few months, you need not only to knock out, but also to wash from the villi. Otherwise, with each use, the vacuum cleaner will suck in less debris, and over time, quite serious engine repairs will be required due to deterioration in performance.
The operation of a standard "dry" vacuum cleaner is a tandem of two motors. One is the motor and the other is the motor that makes the brushes of the first motor work. It should be noted that in addition to the motor inside the vacuum cleaner, these same brushes and bearings can also wear out. In some models of vacuum cleaners (for example, Siemens - Siemens, Vax, Vao, Dyson), you can repair them yourself, in most others it is better to immediately take them to a service center.
After proper disassembly, replacing any broken internal part with a working one is easy. The main thing is to take into account the brand and size of the previous one. In particular, always pay attention to the material and size of old bearings.

Vacuum problems?
Vacuum cleaners bosch are distinguished by their reliability and durability, but even they need periodic maintenance. Parts may wear out and need to be replaced. To ensure the high quality of the appliance and prevent damage, the vacuum cleaner bosch should be completed only with "native" spare parts. They are manufactured in the same factory and equipment as your instrument.
How to disassemble a vacuum cleaner bosch ?
Main components
Bosch upright vacuums use a motor and fan to suck up dust from a surface. These are the most important structural components. Maintenance, repair or replacement is not difficult. The most important thing is to correctly diagnose the problem.
What can fail
A modern vacuum cleaner is a rather complex household appliance, consisting of many components that can fail. Most often this is the on / off button of the device, drive belt, fan or motor.
Fan service
The fan in the bosch upright vacuum cleaner is located under the motor. It is he who draws in all the dust. In most cases, the fan does not need to be replaced, only periodic maintenance. First, you need to remove the engine cover and disconnect the engine from the vacuum chamber. The fan will be located at the bottom of the engine. Next, clean the fan blades and the base with a damp cloth, and also check if they are damaged by hard objects caught in the vacuum cleaner.
Then unscrew the fan from the motor and wipe it on the back.
Make sure that the shaft on which the blades are mounted is lubricated and there are no problems with rotation.
Engine service
Bosch upright vacuum cleaners are distinguished by their durability. However, some will last longer than others. Much depends on the quality of the engine. If the motor of the vacuum cleaner suddenly stops working, then it is necessary to check the power cable of the fan, as well as the on / off switch. It is necessary to periodically clean the dust container, as filling it up leads to overheating of the engine, which interferes with its normal operation.
Official bosch dealers do not recommend making repairs on your own and advise you to contact the official service centers of the company. There, professionals will quickly and correctly diagnose and replace the damaged part.

If you nevertheless decided to start repairing the vacuum cleaner yourself, then you will find “native” bosch spare parts in our branded online store.
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 - awaits us. 
But first we need to pull out the speed controller (a small scarf on colored wires). To remove it, push the speed regulator shaft up and to the left. Now it will not be difficult to get the regulator itself out of the grooves.
