DIY vacuum cleaner nozzle repair

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

Before talking about the repair of a vacuum cleaner turbo brush, you should first understand what it is about. The turbocharged suction system is one of the popular technologies. It assumes the presence of an additional brush. This system is ideal for picking up dust and dirt from carpets.

But no matter how good the vacuum cleaner is and no matter what modern technologies are at the heart of its work, sooner or later it breaks down. And often this happens due to the fact that a complex structure with many moving parts and assemblies is clogged with dust or simply wears out. But do not rush to carry the equipment to the service, perhaps the cause of the malfunction can be eliminated on your own and, in particular, you can repair the vacuum cleaner brush yourself.

The main signs explicitly or indirectly indicating the need to repair the turbo brush of the vacuum cleaner are:

extraneous sounds appeared in the area of the brush;
the suction power is lost;
the brush of the vacuum cleaner does not rotate.

The first step is to determine the cause of the malfunction. If it really lies in a turbocharged brush, then we stock up on the necessary tools.

To repair a vacuum cleaner brush, we need:

crosshead screwdriver
Flat screwdriver
Paint brush
Straight arms

First, unscrew the screws. There are 4 of them in total. In the picture they are marked in red.

Then you need to gently snap off the latches. There are 6. Be careful. The latches are easy to break. They are marked in green in the picture.

Next, carefully remove the lower part and examine the patient

As you can see from the photo, the brush has several faults:

the rotating brush is clogged;
the brush drive belt is loose;
the turbine is jammed.

After inspection, everything must be disassembled and thoroughly cleaned. We disassemble the node in the following sequence:

Let's start with the turbine. The cause of the "wedge" is the drying out of the grease from the brass bushings. To eliminate the malfunction, it is necessary to lubricate the cage and the bearing itself with any thick grease (for example, lithol).

With the turbine sorted out. Now we find out the reasons for the weakening of the brush drive belt.

The reason was that the belt came off the driven gear. Gently rotate the belt counterclockwise and put it back on.

Putting everything together in reverse order. The repair of the turbo cleaner of the vacuum cleaner is completed!

It is almost impossible to do without a vacuum cleaner in everyday life with today's time pressure. Multifunctional equipment allows you to clean your home with high quality, ensuring the cleaning of surfaces and air. There is no need to talk about the useful qualities of washing models. But what if suddenly the equipment is out of order?

Before taking the vacuum cleaner to the workshop, it is worth investigating the breakdown. In some cases, it is possible to repair a vacuum cleaner with your own hands at home.

The availability of self-repair is due to a simple device vacuum cleaner... Experts distinguish three types of structures:

• with air-water mist filter;

• with a stationary dust collector (cyclone).

Any model has the following constituent elements:

• unit for collecting dust (bag, container);

• garbage transportation system (hoses, nozzles);

• main body, in which the unit, dust collector, filtration system is mounted.

Regardless of the type, vacuum cleaners are equipped with hoses, adapters, nozzles, which can also break during operation.

To find out the cause of the breakdown and eliminate it, you will need to disassemble the vacuum cleaner. When performing work, the following rules should be observed:

• first disconnect the cord from the mains;

• disconnect the dust transportation unit (hoses);

• remove and clean the dust collectors, inspect the filters;

• fold back the cover that opens access to the dust collector;

• unscrew the screws securing the cover with access to the unit;

• the fan is detected first, it must be removed (the screw heads do not need to be unscrewed, they sit on the thread, the nuts on the studs must be disconnected);

• remove the motor power connector from the socket.

Successive actions open access to the drum of the network cable.

What breakdowns of a vacuum cleaner happen more often, how to fix them

Before disassembling the case, it is worth checking all the filters in the vacuum cleaner. It is their clogging that leads to a decrease in the power of equipment, automatic shutdown or even burnout.

It is easy to clean the foam rubber filter pads, just rinse them under running water and dry them naturally. If a lot of dust accumulates on the paper filter, it is recommended to replace it.

It is very difficult to purchase HEPA filters for some vacuum cleaners due to the renewal of the assortment with new models. You should not despair, the cleaning device is easy to make with your own hands. The basis is taken:

• the body of the old filter (in the form of a frame);

• air filter insert for any SUV (the most affordable for UAZ).

First you need to remove the paper accordion from the frame, which you need to thoroughly wash, dry and treat the surfaces with an alcohol-based solution (for the purpose of degreasing).

Further, the salon insert is cut out according to the parameters of the frame and fixed on it with the help of glue, having previously applied it along the contour. An unused filter (from which the trim was made) should be packed in a plastic bag so that it does not suck in dust during storage. You can replace the liner again later.

In addition to filters, affect the work vacuum cleaner the hose may be clogged. Often there is a cork of hairs or wool and a lot of dust. The dirt should be removed carefully so as not to damage the walls of the accordion.

If the hose is clean and the suction draft of dust is poor, it is worth inspecting the surface of the hose for a crack. To eliminate this problem, you can use any available means: scotch tape (better foil-coated, it is more elastic), a patch of thin rubber, a silicone pad, etc.

If a break occurs in front of the docking station, then it is enough to cut off a piece of the damaged hose and connect a slightly shortened version to the crimp. It is also easy to restore the integrity of the transport part in case of a break in the middle using a heat-shrinkable tube. It is cut to the required length and put on the hose, bringing it to the point of rupture. After heat exposure, which is created by an ordinary household hairdryer, the tube fits snugly against the damaged area.

After properly disassembling the insides of the case, you can reach the power cord drum. Often, the cable is simply disconnected from the node, which cuts off the mains power supply. If a broken wire is detected, a new connection should be made. All twists or joints must be insulated with a special tape.

You can start repairing the engine only if you have experience with electrical equipment. For high-quality performance of work, it is necessary, in addition to knowledge, to have special measuring instruments.

Eliminating small problems can help reduce household spending. But there are times when it is more expedient to seek qualified help. It will cost less in the long run.

So, a trip to the workshop is required if the following signs of serious breakdown are noted:

• when the engine is turned on, a third-party noise, hum, vibration is heard;

• overheating during short-term operation of the vacuum cleaner;

• smell of burnt wires;

• automatic shutdown of equipment;

• with pops, sparks and other third-party sounds.

If a suspicious sign is found, turn off the vacuum cleaner immediately by unplugging the power cord.

Regardless of the type of vacuum cleaner, the heart is called the engine. Television programs like to depict the creation of a vacuum, which, in our opinion, is an inept manipulation of words. The motor draws in air by the blade, the filter keeps the moving parts from dust. Each bearing is provided with an insert for this purpose. The engine is devoid of protection from vacuum ... Do-it-yourself repair of a vacuum cleaner is advisable when the heart of the device is functioning properly, there is a need to replace, modify the brushes, lubricate the bearings. It is charming that the devices are similar from the inside, like two drops of water. The mechanical part, the device for collecting dust, filters, brushes, hoses, housings vary. Accessories are an essential part of the appliance. The device of the vacuum cleaner, the basic idea remains the same!

The heart of the vacuum cleaner is rightly called a motor, traditionally a collector motor. Let's take a quick look at the design of an irreplaceable product and create a clear idea. In an asynchronous motor, a rotating field is created by the correct distribution of the phases by the windings, the winding collector commutes in series. There are unpopular exceptions. The direction of movement is determined by the direction of engagement:

The current flows, the fields work for attraction.
The current flows, the fields are repelled.

As for the question why the rotor turns exactly in this direction, not opposite when connecting the windings unidirectionally, the answer is revealed by the mutual arrangement of the brushes and stator coils, the structure of the collector. The number of coils is wound on the armature, equal to the number of contact pads of the shaft. The brushes feed a single winding at a time. Then the shaft rotates a certain angular distance, the next coil is energized. One revolution passes, the cycle begins anew.

Imagine the stator pole (so far only one - not two), located at the bottom. Suppose, at the initial moment of time, the brushes are set so that the armature pole is fed to the left of the building 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 managed to take the place of the previous one. This happens as long as the current exists. And there is no difference, constant or variable. The collector motor will run driven by the direction of the field. The speed of rotation is not determined by the frequency - by the design of the mechanical part, by the magnitude of the voltage.

Now if the fields are attracted, the rotation will start counterclockwise. By the time the stator and rotor poles become opposite each other, the power will be transferred to the next coil, which will begin to create the required force. The cycle is circular. Now the coils. Brush motors are equipped with a pair of stator windings for direct current because the alternating current encounters too much resistance from the inductors. This is why some brushed motors are designed with separate stator leads. It will allow you to use one instead of two windings. It is clear that the load capacity drops significantly. But losses are decreasing.

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 correct direction of inclusion (wrote above). Reversing motors have a special power relay that switches the poles in proper order. For comparison, in an induction motor, a similar 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 try to imitate the second winding. Simply put, the efficiency of three-phase asynchronous motors is higher. The brainchilds of Nikola Tesla and Dolivo-Dobrovolsky are used by industrial equipment, in the 90s they were replaced by collector equipment from household appliances (vacuum cleaners were traditionally supplied with graphite brushes before the restructuring).

Two brushes are used to transfer current to the armature. The difference is leveled, where the plus, where the minus, the direction is provided by the correct commutation.

Is it possible, by changing the order of connecting the brushes, to make the motor rotate in the opposite direction. The polarity of the field is reversed. This technique is used to obtain a constant voltage reverse. When doing self-repair of vacuum cleaners, remember the correct position of the contacts.

A tangential fan is hidden behind the filters for coarse and fine air purification. Air enters in the center, is discharged to the periphery, moving forward, enters the room through a HEPA filter that traps particles of a few microns (micrometers) in size. The blade is covered with a cover, the part is made in the form of curved aluminum partitions between two metal planes. Closed channels are obtained. The engine is enclosed by 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 W, the suction will be 350 W.

Brushes are fixed in mines, it is useful for beginners to know: this is a typical pencil graphite (carbon, coal). You can, if necessary, sharpen the parts, adjust as needed, so that they become in place. If the area of contact with the collector is small, it is not scary, gradually the brushes will wear in. The tips are slightly grinded in a semicircle inward. Each brush is pressed by a spring through which the current passes, the measure will provide a long service life to the products. The carbon will work until it wears down to the ground. However, the copper collector must be kept clean. Wipe with your favorite product if necessary, remove the oxide film to a coppery shine.

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 and the rear bearing 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 gets in there too. The anthers are carefully removed with a screwdriver if necessary to lubricate the parts. Suitable: composition HADO, Litol - 24, EP - 2. The grease is put inside, the boot is put in place.

Do-it-yourself vacuum cleaner repair begins by removing the case. In each case, the methods are different. Filters blocking access to the engine are removed. The electrical installation is disconnected (the vacuum cleaner is unplugged), the plastic motor housing is unscrewed from the base. Remove the motor from the casing, after which the fan is removed. The nut has a left-hand thread, twist carefully. The fan is followed by a collector-cover, under which the electrical part is hidden. The further course of operations is clear from what was previously read up to the removal of the rotor.

If necessary, the bearings are racked off with a threaded remover or a hydraulic press. Aids are being used. Small balls with a diameter extending into the bearings. It is recommended to flatten on one side so as not to roll. Reverse mounting is done in a similar way. If you hold the armature by the bearing in your hand, the rotation should be fast, quiet, confident. When lubricating, the outer boot is removed, take the trouble to put new spare parts on the same side.

Other vacuum cleaners have two motors.The second is located on the brush, where it makes the villi move. Cyclonic models use a turbo, moving air does the work. Constructive refinement simplifies the manufacture of the hose, eliminates one big problem when the wire breaks in the thickness of the rubber. Of course, modern means will allow you to accurately determine the location of the incident, it is better to avoid breakage altogether. The idea of the designers, who placed the motor inside the brush, is easy to understand: there is no need to press when cleaning, the weight is decent. Do you like it, decide for yourself. In the opinion of the editors, the brush should be light to make it easier to operate.

Repair of washing vacuum cleaners does not differ from that described above. However, the units contain a pump that supplies water to the hose. We will return to the question in the reviews later. As for the inlet path, the configuration does not differ from the usual one, excluding the presence of a water filter. Most look like dull boxes filled with water. In some vacuum cleaners with an aquafilter, thin streams of water hit the junction of the hose and the body. Primary dust collection is in operation. However, it is difficult to notice the malfunction. It's another matter if the vacuum cleaner is equipped with a self-diagnosis option, which will tell you the location of the breakdown.

The repair of robotic vacuum cleaners is closely related to the field of electronics. There are nothing service mechanisms at all. However, you will find the engine in a reduced size. Most of the functions are implemented in microcircuits, the memory accommodates various programs. Repairing Electrolux vacuum cleaners will seem like child's play compared to the task of adjusting the work of Rumba or Scuba by the American company iRobot (a developer of US army and police automation). A significant disadvantage of robots is the impossibility of cleaning uneven surfaces. Electronic servants lack the ability to create a vacuum ... use a rotating brush to sweep away dust.

Today it is hardly possible to find a family in whose house there is no vacuum cleaner. This irreplaceable assistant has become almost the main household appliance, and the choice of its technical characteristics and quality must be approached with knowledge. But, no matter how regrettable, no matter what famous manufacturer this device may be, all the promoted brands have a weakness for tearing parts. Unfortunately, the flexibility of hoses, even with the toughest materials, is not unlimited. And noticing a gap in the places where it bends, the question arises: is it possible to repair the vacuum cleaner hose with your own hands? Let's see how this can be done.

Depending on the location and nature of the damage, there are several ways to repair the vacuum cleaner tube so as not to spend extra money on the unplanned purchase of expensive household appliances.

If the damage to the hose is in the middle, then you can repair it using a regular bicycle tube. To do this, proceed as follows:

Assess the extent of the damage and cut the tube to the length you want, after checking the rest of the part for integrity.

Important! The chamber must be intact and not let in air. Otherwise, there will be a loss of power.

Using a camera, connect the two ends of the hose by pulling it from the top.

Important! If you find it difficult to stretch the camera, you can use soap - lubricate the ends of the corrugated tube with it. This will help to eliminate the breakage without much effort.

After successfully connecting the hose, unscrew the ends of the chamber, wipe the entire corrugation dry.
Glue these places with Moment glue, wrap the camera back.

Important! For greater reliability, the glued places can be wrapped on top with adhesive tape or electrical tape.

Important! In order for household appliances to serve for a long time, they need care and regular cleaning. A vacuum cleaner is no exception. Read in detail on our website about how to clean the vacuum cleaner so that this procedure does not cause you any difficulties.

Depending on which fitting the hose broke off:

Cut the piece at the torn area.
Clean the fitting from dirt and remains of a torn hose.
Connect the fitting to the corrugated tube.
Since the corrugated tube has stiffening ribs for convenient and efficient use of vacuum cleaners, you need to screw the hose into the fitting or base of the device body with glue or using electrical tape.

If you have a problem with an element that breaks off at both ends, then in order to repair the vacuum cleaner hose with your own hands, you need to disassemble the mechanism:

Use a screwdriver to pry out the remaining pieces of the plastic sleeve into which the damaged part was previously inserted.
Bond the part with sealant or epoxy.
Leave alone until completely dry.

Sometimes it happens that due to the poor quality of materials, in some places the hose begins to siphon - small cracks or breaks appear in it. These problem areas can be corrected with a medical plaster or PVC insulation.

In order to repair the hose from the vacuum cleaner with these means:

Apply an adhesive patch with PVC insulation carefully wrapped over the tears. Try to wind it as tightly as possible, with a small margin on both sides, because the corrugated tube can allow air to pass through.
In places where cracks have formed, carefully saw through the rigid base and wind the hose on top of each other. Then wrap electrical tape or scotch tape on top for tightness.

Important! If not only the hose is broken, you need to understand the causes of the malfunction. You can do this yourself if you, with our help, figure out how to disassemble the vacuum cleaner.

The second end of the shaft is used to drive the brush roller through the belt. The bristles on the roller picks up dust from the surface to be cleaned and directs it inward following the intake air. The distance between the brush roller and the floor is adjustable, which allows cleaning various surfaces. Contaminated air passes through the fan and then enters the dust bag. It is made of breathable paper. It does not allow dust to pass through, but allows air to pass through. The efficiency of the system is high, but it has one drawback. All particles come into contact with the fan, which often leads to fan breakdown and combustion of the electric motor when it gets jammed when stones and metal objects get inside the fan.

Cylinder vacuum cleaners have a different device.

In them, the dust bag is located in front of the fan. The sucked-in air enters the bag and particles are retained in it, and the cleaned air enters the fan, passes through the electric motor housing, thereby cooling it well and then is thrown out into the outlets on the device housing. A flexible hose is attached to the air intake opening, which is supplied with a wide variety of nozzles. In case of damage to the dust-collecting bag in a vacuum cleaner of this design, an additional filter is provided, which is installed between the dust-collecting bag and the fan.

Combined vacuum cleaners were created by designers with the expectation of avoiding the disadvantages of the two types of vacuum cleaners. In these vacuum cleaners, air and dust are drawn into the brush roller compartment and further into the dust bag.

All modern vacuum cleaners are constantly being improved and equipped with various functions. Let's consider them in order.

The adjustment allows you to decrease and increase the performance of the vacuum cleaner. This is ensured by smooth regulation of the voltage on the fan motor using a small circuit on the seven-story.

When carpet or furniture is cleaned, the dust control system turns on an indicator when the dust in the air drops below a threshold.

Automatic cord rewind

The power cord of a modern vacuum cleaner is quite long, so they are equipped with a spring-loaded drum, which, when you press the cord rewind button, pulls the cord into the body of the device.

These vacuum cleaners are powered by a battery that powers the vacuum cleaner's fan motor.

This concludes the review of functions and proceeds directly to the repair of vacuum cleaners.

Poor absorption

1. Incorrect power setting ... In this case, check the position of the power control. It can stand in reduced power mode.

2. Dust bag is full ... Empty dust bag. Also remove and check the engine dust filter. If it is clogged, knock it out or wash it with soap and water and dry on a flat surface. Replace with a new one if necessary.

3. Clogged hose... Remove the hose and visually check for foreign objects accidentally caught in it during cleaning.

4. Air leaking from a semi-hermetic system ... Check the quality of the connection of the suction hose to the body of the vacuum cleaner, as well as the hose for integrity (it must not have cracks). Remove the cover and panel and check if the gaskets and seals are intact. Replace those that are torn or out of shape.

Good suction, but poor collection of debris (in upright vacuums).

1. Incorrect roller position ... Check if the height of the brush roller is set correctly to the surface to be cleaned.

2. Brush wear ... Check the length of the bristles on the roller. If the wear exceeds the norm, then replace the brush roller with a new one.

Brush roller does not rotate.

1. Torn belt ... Disassemble the vacuum cleaner and replace the belt with a new one that matches your model.

2. Seized roller bearings ... Remove the brush roller and remove the end caps. At each end, check for thread or hair on the bearings.

The smell of burnt rubber.

Belt slippage ... Check the belt tension. If it is loose, replace it with a new one. Check the bearings for ease of rotation of the brush roller. If it does not rotate smoothly, check the bearings and replace or lubricate if necessary.

The vacuum cleaner does not turn on.

1. The plug is not included in the socket ... Check if the plug is well inserted into the outlet. When working with the cord fully extended, this is often the case. Also, make sure the power outlet is energized.

2. No power supply ... Check the power board, you can often find a knocked-out circuit breaker or blown fuses there.

3. Defective plug or fuse ... Check that the plug is connected correctly, as well as the built-in fuse, if any.

4. Open in the power cord ... It is necessary to check the power cord, for this it is necessary to disassemble the vacuum cleaner, find the place of the electrical connection of the end of the power cord and ring its veins for an open. Replace if necessary.

5. Motor overheating protection tripped ... Some models of vacuum cleaners have built-in protection against overheating of the drive. It is called a thermal fuse. The operation of this protection can be caused by clogging of the dust bag, filters, due to clogging in the air ducts. Let the vacuum cleaner cool down for half an hour, then plug it back in and check its operation. If it does not work, then the reason lies elsewhere.

6. Faulty switch ... Remove the cover from the vacuum cleaner along with the switch and carefully disconnect the wires from it. Check the switch with a tester. To each contact of the switch, attach the probe of the device in the resistance measurement mode and turn the switch on and off. If the tester does not show anything, this indicates that the switch is faulty.

7. Defective motor ... Carefully disassemble the vacuum cleaner, find and remove the electric motor with a fan. If you have not read the article on checking the motor windings, then I advise you to read it. Check the condition of the brushes on the motor. If they are badly worn, replace them with new ones. Perhaps there may be a break in the windings of the electric motor.

To check the presence of an electrical circuit in the electric motor circuit, attach the tester probes to each brush in the resistance measurement mode. If the device shows infinity, then perhaps the brushes do not adhere well to the armature collector and it is necessary to replace them with new ones. If there is a resistance tester reading of several ohms, it is necessary to make sure that the stator windings of the electric motor are in good condition. To do this, find the ends of the windings and call them with a tester. If they have an open circuit, then the electric motor needs repair. Very often the electric motor of the vacuum cleaner burns out from overheating or its winding is damaged.

Repairing the electric motor of a vacuum cleaner is quite complicated and must be carried out by a specialist. In the future, I will write an article about checking and step-by-step overhaul of collector electric motors. If you have a washing machine, you may need to repair your washing machines. So we read. I also recommend reading the posts on quartz watch repair, electric shaver repair and blender repair. Good luck with your vacuum cleaner repair! Till!

If you have torn vacuum cleaner hose, then do not rush to throw away the vacuum cleaner and buy a new one, especially if the old vacuum cleaner is completely tired of you: excellent suction power and the engine works without interruptions.The hose usually breaks at the strongest points. folds - this is either in the place where the hose is attached directly to the vacuum cleaner itself, or in the place near the handle of the hose holder. I have seen many times how a torn hose is wrapped with duct tape or duct tape. But in this case, such repairs are usually short-lived, and it looks somewhat rough and pathetic.

The hose can be repaired by cutting off the torn part. In this case, it will be shorter by 3-5 centimeters, but it will look and work like absolutely new.

For repairs, we took a hose with a power regulator on the hose handle:

This hose differs from the usual one in that it uses two insulated wires as a spring, through which voltage is supplied to the switch and the power regulator (rheostat) located on the holder handle. As expected, the hose broke at the point where it was attached to the vacuum cleaner:

Since this hose is wired, it has two contacts in the form of a plug for an electrical outlet, which close the electrical network when connected to the body of the vacuum cleaner:

First, you need to disassemble the mount to access the hose wires. To do this, you need to use a Phillips screwdriver. We unscrew the two self-tapping screws on the holder mount:

On the front side of the hose holder there are round technological holes for easy removal of the fastener. With the same screwdriver, gently press into these holes inward and at the same time upward to remove the spring fastening mechanism

Thus, the mechanism of the spring fastening of the hose is slightly opened:

After that, the fork with the spring-loaded mechanism of the holder is removed:

Carefully remove the spring latch:

Next, unscrew the plastic hose guide:

Unscrew counterclockwise towards ourselves. It holds tight enough, but after a few seconds it gives in:

The wires are released, and by the same twisting, the hose itself is removed from the nozzle of the vacuum cleaner:

The plastic flexible sheath of the torn part can be easily cut with ordinary scissors:

We release the wires glued to the shell from it and cut off the excess part with side cutters:

When trimming wires, note that it is best to trim an integer number of turns (one, two, three, etc.). This is necessary so that when assembling in a natural position, the suction end of the hose is directed downward, as before, and not somewhere to the side or upward.

Next, we will use a soldering iron to solder the ends of the wires that were previously soldered to the wire - the spring, which were cut off:

Solder them again. To do this, you need to clean the new ends of the wires from insulation (you can use an ordinary construction knife):

For a better grip with solder, it is better to process the cleaned ends with rosin:

Then we solder the ends of the wires with pins to our cut part. They must not touch bare wires — pay special attention to this!

Everything is ready. Now you can reassemble what has been disassembled. When assembling, we first screw in the vacuum cleaner nozzle:

When planting wires, it is convenient to use electrical tape to fix the wires:

Also, when assembling, it is better to first install the holder with a spring fastening, and then put on the plastic hose guide, since it goes over the top of the holder:

Video (click to play).

Next, screw the screws back. That's all. We receive an updated hose. All the work took about 30-40 minutes, no more. Of course, the attachments for different brands of vacuum cleaners are different, but the principles are common to all.
