A do-it-yourself stationary high-pressure washer can be made on the basis of a special pump for sinks, a high-pressure hydraulic pump for special equipment (like NSh) or an air compressor. When the question arises whether to buy a factory-made pressure washer or make one yourself, there are several factors to consider. A homemade car wash using improvised means is usually cheaper than a ready-made MIA with similar parameters. Provided that components are chosen wisely and are of high quality, it surpasses factory ones in reliability and is not inferior to them in performance.
In this material we will look at how to make a high-pressure washer with your own hands and look at the three most popular design options and answer basic questions about homemade MIAs.
External car wash units
External components are mounted on a frame, which is better to make yourself or choose a suitable ready-made structure. Usually the frame is made on the basis of a profile or curved pipe. You can install wheels on the bottom so that the sink is not stationary, but mobile. Stops, handles and clamps will help you move the device.
- Hose. If you have sorted out the water intake, you need an element through which the liquid will begin to flow to the machine. Choose reinforced rubberized hoses or plastic products. Just make sure the hose is durable and has tight connections to the water intake. If necessary, you should be able to quickly repair the hose and change it.
- Connections. It is better to connect areas where elements are connected to each other and come into contact with water using fasteners made of corrosion-resistant materials. For example, bronze or brass.
- Gun and nozzle. You can take a ready-made sandblaster or another suitable gun that has a nozzle. Outwardly they resemble pistols at gas stations. The water jet should only be released when you press the button. It’s better to take a ready-made gun and not worry. My advice to you.
We do everything consistently and carefully, connecting the elements tightly together. In fact, selecting parts and creating a full-fledged sink from them is not an impossible task.
But you will still need a cutter to cut the holes, a whole set of different components. It is far from certain that they will be at hand or suitable in size, type of material, and so on. Someone makes sinks from NSh 10 (gear pump) and is happy with the result. Others twist and turn something, but in the end they go to the store and buy a foaming agent, connecting it with the purchased branded sink. Although a foam generator can be made from a compressor and auxiliary mechanisms, I would prefer a ready-made product.
In some cases, it is better to think about which sink from a leading manufacturer to take to wash your car, rather than spend several days unsuccessfully trying to assemble a sink from scrap materials.
I am not at all opposed to making useful things with my own hands. But in terms of washing there are many pitfalls. As for me, it is better to spend more money and less time on a proven Karcher factory car wash, for example, than less money and more time on a homemade device. It remains to be seen how this homemade product will work and what surprises it will reveal during operation.
The rating of factory sinks clearly demonstrates the leaders of the segment. Will you be able to achieve similar characteristics to such devices by doing the washing yourself? Hardly. Can you save money? Probably yes.
Device
Now it would be useful to consider the structure of the sink and understand what components it consists of. The design of any high pressure washer will consist of 5 main and a lot of auxiliary elements.
If we talk about the main ones, we are talking about:
- motor;
- pump;
- pump;
- fuse;
- filters.
Now let's talk about them in a little more detail. The motor is the basis of the entire structure. It is thanks to its presence that it is possible to achieve pump operation that can be called stable. The electric option will be the most common, although there are also autonomous solutions. If we talk about autonomous options, then the fuel for them will be either diesel or gasoline. If we talk about a pumping unit, then its main purpose will be pumping water from a special container or a centralized network.
If we are talking about a centralized option, then the sink must be equipped with special hoses.
The pump is directly responsible for increasing the pressure. An important criterion for this part is wear resistance. Here it should be said that this parameter will depend on the material from which it is made. Most often these days it is made of plastic. This option is not of very high quality, since if you use the device for more than 20 minutes, its failure is almost guaranteed. There are brass solutions that will be more reliable.
It should be said that the models on the market, as a rule, are equipped with plastic options. For this reason, a self-made model can be significantly more reliable.
The motor fuse is responsible for controlling the operation of the entire pump. As soon as the water level reaches a critical level, rotation of the engine becomes impossible. This is usually observed when liquid enters but does not come out due to the fact that the hose is blocked and the type of washer in question continues to operate.
The filter is the main element of protection that protects the sink from mechanical problems due to sand or other foreign particles of considerable size getting inside through the nozzle.
After washing the engine the car does not start, what should I do?
During the engine washing process, unpleasant and unnoticeable breakdowns may occur or water may enter electrical appliances, so the car may not start.
- If after washing the engine the car does not start, then you first need to inspect the spark plug channels, electrical connectors, generator, starter. If moisture is detected, parts must be thoroughly wiped or dried.
- Problems with engine operation can occur if the electrical circuit is broken. This could be a forgotten connector chip that was disconnected before washing, or an awkward movement by a motorist that led to a broken wire.
- If after washing the engine the car does not start, and the Check Engine light comes on on the instrument panel, then it will be quite easy to figure out the reasons for this yourself using the ELM327 auto scanner.
For those motorists who do not have free time or do not like to tinker with the car, the best option, in our opinion, would be to visit a car wash. Professionals will do the job of cleaning the engine compartment quickly and efficiently, and the driver won’t even get his hands dirty. In any case, washing the engine once or twice a year is within the capabilities and means of every car owner.
What is a pressure washer?
Today, you no longer need energy and time to fight dried-on dirt and dust that has clogged up in nooks and crannies, because every year new models of high-pressure washers appear on the market. These devices are used for washing windows, cars, walls and doors of houses, barbecues and other objects that are difficult to clean with a rag or brush. Strong water pressure copes with this task much more effectively and saves money spent on washing the car at a service center; water consumption is also minimal. Therefore, having such a sink in your arsenal is useful for everyone.
The leading companies in the production of high-pressure washers are the German companies Bosch, Karcher (hence the second name for the wash - Karcher) and Elitech. The average price of these sinks on the market starts at 10,000 rubles. Inexpensive car washes cannot be used for more than one car per day, and the most expensive models are limited to seven cars.
Requirements for a homemade Karcher
A properly assembled homemade Karcher is practically no different in its technical characteristics from the branded one. The main thing is to take into account the requirements for the unit:
- the product must have high performance, which refers to the volume of water required to be pumped by a pump for a certain time. This determines the force of pressure;
- it is necessary to take into account the pressure exerted on the surface by the force of the water flow. Cleaning the bottom of a car will require a lot of pressure;
- It is imperative to install an additional cleaning filter on the structure, which will prevent the ingress of microparticles, chemical elements and iron elements. It will also protect the device from mechanical influences.
Making your own car lift
To wash or perform various repair work, the car owner may need a lift, which can be made independently.
To make a mechanical lift that will be installed in the garage, you will need the following parts:
- A worm gearbox, the load capacity of which must be at least 300 kg, and the gear ratio must be at least 60 kg.
- Three steel corners measuring 7.5 by 7.5 by 0.8 cm.
- Steel plate 1 cm thick.
- Two strong iron chains.
- Durable hook.
- A few bolts.
- Steel cable 5 mm thick.
- Two star-shaped keys of different diameters.
It is also useful to read: Effective means for washing a car engine without rinsing with water
Lift assembly:
- We fasten the steel corners using welding or bolts on opposite walls.
- We install a steel plate on the corners of the lift and secure it with 7 bolts.
- We install the used worm gearbox on the plate.
- We fix the large key on the gearbox drive.
- We drill holes in the plate and thread a chain through them, after which it needs to be closed into a ring.
- We attach a key of smaller diameter to the output shaft of the gearbox.
- We drill two holes in the lift plate.
- We pass the second steel chain through the holes.
- The chain is thrown over the smaller key, and the second part is attached to the hook.
This way you can easily make a simple car lift yourself, which can be used in the garage for washing the underbody and performing various repair work.
: Disassemble the mop head
This is a fun step. You start with 8 mops and end up with an amazing car wash hyper mop.

- Cut the blue cord
- Tighten the zipper slightly
- Wrap the mop around the hyper mop handle
- Tighten the zipper
- Go back to step 1 and repeat until you have no mops left
The hyper mop is almost ready!
The subtleties of making a mini-sink yourself
During the assembly process of a car wash, there are several important points that determine the safety of further operation and the absence of malfunctions.
The frame is the basis of the entire structure:
- it is planned to manufacture a system with optimal dimensions, for which suitable pipes are selected - round, curved;
- in addition to the wheels, it is advisable to install clamps at the bottom;
- handle - makes transportation easier.
Grounding – safety element:
- a three-core wire is selected;
- you will need a plug with a grounding terminal;
- The socket is grounded.
After preparation, several main steps are performed:
- Electrical equipment is installed on the frame, including a motor, pump, and other structural elements.
- A gun with a nozzle is attached, supplying water after pressing a special button. Such devices are used by professionals, but they can also be easily purchased in a store.
- A high-pressure hose is being installed.
After completing the assembly, connect to the water supply. A 7 m long hose is suitable for this.
How to avoid unexpected device breakdowns
When thinking about how to make a car wash with your own hands, it is advisable to ensure optimal operation, preventing the need for subsequent restoration.
Important points about using the installation:
- before starting, all connections and fastenings are checked;
- the filter element needs to be regularly cleaned to remove dirt;
- You should not often use the equipment at full power;
- Installing a battery will protect the device from power surges.
Secrets of designing a foam generator
A car wash is used to remove debris, dirt from the car body and other parts. A foam generator allows you to maximize the quality of cleaning. It's also easy to make yourself.
A small amount of tools is selected:
- roulette;
- knife;
- Bulgarian;
- wrenches;
- pliers.
When thinking about how to make a foam generator for a car wash with your own hands, it is worth choosing suitable materials and parts for assembly.
Basic moments:
- A pipe with a length of at least 50 cm is required. It is filled with polyethylene sponge for subsequent foam formation.
- A filter is installed in the form of a mesh to prevent filler from getting into other units.
- One edge of the pipe must be plugged and a tee must be installed to subsequently secure the foam concentrate tap.
- Using a fitting, connect the pipe and hose intended for foam.
- A valve is connected to the other end, providing a flow of compressed air masses.
The characteristics of the foam that will be obtained as a result of the operation of such an installation are determined by the length of the pipe used. The density of filling the surface with a washcloth requires attention. For filling car cosmetics, a container that can withstand the pressure exerted by the system is suitable. A car wash and a foam generator are useful units that simplify the process of car care. They can easily cope with loads in home use, perfectly replacing factory tools.
The cleanliness of a car is not only an aesthetic indicator, but also protects the product from negative environmental factors. After all, stuck and dried dirt may contain aggressive elements that damage the paintwork. Also, long-term and regular contamination of the body can lead to irreversible damage to the metal, including through corrosion on individual elements.
In this case, regular visits to a car wash or home water treatments can help. But in the second case, you need to buy a washing device or make a car wash with your own hands from improvised materials. Prices in stores generally start from 5 thousand rubles. The upper threshold may not stop at 20 thousand. Therefore, we will do it ourselves.
Procedure
- Now let's proceed directly to assembling the type of sink in question. First, it would not be superfluous to check the functionality of the pumping equipment. To do this, we attach two hoses to it. The first will serve to receive water, and the second will supply it to the gun. We unscrew the special clamp and then put it on the hose. After this, you should tighten everything and check the tightness of the connections. We take a blow gun, which is also connected to the structure with a hose and secured with a clamp.
- It often happens that a blow gun comes with nozzles that are slightly unsuitable for connection to the structure. To solve this problem, you can unscrew the nozzle and screw in a carburetor jet, which will fit perfectly on the thread. Many people use a carburetor jet from a Zhiguli car. This solution is necessary to reduce the hole in the gun, which allows you to create a more powerful compact jet.
Now we need to deal with the electrical part. First you need to connect the activation/deactivation toggle switch to the wire. You can purchase such a solution at any store that sells electrical spare parts. If suddenly, for some reason, you want to make such a device mobile, then take a screwdriver battery and solder the wiring to it along with the contacts so that the solder in no way interferes with the charging connection, and the battery can be recharged if desired.
Now we fix the wires with electrical tape. Now we connect the wires themselves to the pump. At the same time, we connect the circuit using contacts.
- If you want, you can also make an extension cord with a wire of different lengths. Such a device will not be superfluous if you want to use a car wash by connecting it to the car’s battery. Now the assembly of the device parts in a housing made from a plastic bucket begins. To do this, we punch 4 holes in its wall using the drill mentioned above. We attach the pump to the wall of the bucket and tighten it with 4 screws and nuts.
- At the bottom of the bucket you can make a mount to secure the screwdriver battery. We also make fastenings for the extension cord. It will be located under the lid. Now we drill a few more holes in the container for the gasket and for connecting the hoses. Everything can be neatly placed in this plastic bucket. True, the container will need to be carried separately, but you can somehow come to terms with this drawback.
- In general, it should be said that there is nothing difficult in assembling a mini-sink with your own hands from available elements. The main thing that is required is the necessary components, basic technical knowledge in the field of electronics, the specified tools and the desire to make a mini-wash no worse than the one sold in specialized stores at an incredible price.
We make equipment ourselves
First of all, you will need to choose a suitable pump for washing. If you plan to operate the equipment for commercial purposes, choose industrial equipment. The main principle remains the choice of a plunger pump equipped with ceramic pistons. The crank mechanism increases the service life. The main parts of a high pressure washer are:
- washing filter;
- hoses;
- additional nozzles;
- water containers;
- detergents;
- sandblasting for washing;
- durable wear-resistant body;
- High pressure pump;
- engine (gasoline or electric).
- The container is equipped with a pump, and the connections must be completely sealed and durable. Fixation involves the use of couplings.
- On the other side of the tank you will need to fix a hose that will supply water.
- The hose is equipped with a tip that directs the water stream.
An auto-loading valve, available in two variations, will need to be connected to the pump. The first type is represented by a closed valve. The system releases pressure after closing the gun, and then water is pumped from the outlet to the inlet. It is recommended not to operate the device for more than 3 minutes. The valve with inlet is convenient. The liquid is transported through the collector to the container or to the sewer immediately after the pressure is released (depending on the connection option for the sink).
There are two ways to connect the motor to the pump. If you have a motor with a full shaft, it can be connected directly to the pump. The motor shaft is placed on the front bearing, creating additional load. This technique shows the most economical results. If you make a sink with such an engine with your own hands, it will have a significant service life between repairs. This is caused by high starting loads. It happens that it is not possible to remove the pump shaft from the engine. In this regard, it is advisable to install a soft starter.
Another method of coupling the motor to the pump is provided, in which a clutch is used. It is used as a cushion that softens the shock during equipment startup. The coupling serves as a protection that prevents the shafts from being damaged. In order to reduce the load during startup, a soft start can be used. Thanks to this element, it is possible to gradually increase the power in the system.
The sink must be connected to the water supply system using a hose. The connection hose must be at least 7 meters long. The length of the hose allows you to smooth out pressure drops in the water supply. Provide a filter for washing. It is recommended to use a hose with a check valve, which increases the operating pressure.
Main components
Since we do everything from improvised means, problems may arise with such a parameter as reliability. I believe that any sink or foam generator should be assembled in accordance with GOST and other requirements. If you violate all the recommendations and sculpt a structure from the first spare parts you come across, it’s better not to start.
If you are ready to act consistently and competently, then maybe something good will work out. Homemade car washes are not a myth at all. A lot of people, including my friends, collected them. They work well. Although my foaming agent works no worse. Yes, I bought it and I'm not ashamed of it.
So, since we are talking about homemade sinks, let's see what components they are assembled from.
- Pump or pump. The first priority will be to find a pump. Since a sink is a water supply device, there is no way to do it without a pump. Moreover, so that water comes out through the nozzle under high pressure, capable of removing dirt from the surface of the machine, we select the pump at 150 bar. Some charge more, but this is unnecessary. Otherwise, the paint will come off along with the dirt. The block head must be made of brass or bronze. Such materials are least susceptible to corrosion, and therefore the device will last a long time. Supplying 15 liters of water per minute is enough to thoroughly wash your car.
- Electrical engine. The next in line will be a 220V electric motor. In addition to it, you need a condenser unit so that the sink starts without problems. The higher the rpm, the better the performance. Pumps that are too fast and produce a high speed will wear out quickly. Don't take them. A consumption of 2-3 kW and a rotation speed of no more than 2000 rpm is considered optimal.
- Clutch. It is needed to connect the pump to the engine. Some people also install a belt drive in one stage. With the help of this gearbox, the speed and load of the engine with the pump are balanced. The gear ratio must be selected based on the required output parameters.
- Water container. Use a tank that you can power from a constant source of water. This could be a regular tap or a well, for example. If the water is dirty, install a filter at the inlet. The main reservoir will serve to add car washing shampoo.
- Performance regulator . A special valve must regulate operating parameters and, if necessary, redirect unused water pressure into the container. This reduces the load on the pump.
We've sorted out the basic elements. But there is also a hose, nozzles and other components that are part of a homemade sink. Or think about which one to choose among ready-made sinks sold in stores.
Processing of models 2105, 2107
Before applying anti-corrosion material to the VAZ-05 and -07 you need to:
- dismantle all parts that interfere with access to the cavities being processed, that is, shields under the front fenders, spare tire, trunk cover, sidewall linings;
- cover the oval openings of the sills at the base of the pillars with something so that when washing, water does not penetrate into the interior;
- Rinse all areas where anticorrosive is applied with water. But before that: pull out the plugs in the rear wheel arches, in the beam of these arches, in the cross member under the front seats, in the niche for the spare tire, and clean the drainage holes. After washing, blow everything with air and dry it.
The following cavities are treated with anticorrosive agents first:
- Between the rear fender and the wheel arch
- Rear side members
- Rear floor cross members
- Recess under the fuel tank
- Rear lower cross member
- Recess for spare wheel
- Mudguard strut
- At the connection of the front flap with the side of the wing
- In the hood pockets
- At the connection of the front panel with the side of the wing
- Front upper cross member
- Front lower cross member
- To the front suspension buffer bracket
- In the front fender pockets
- Doors
- Thresholds
- In the jack bracket
- Cross members between rear wheel arches
- Rear side members
- Front side members and their reinforcements

After the anti-corrosion treatment of the car with your own hands is completed, you need to remove traces of mastic using a swab moistened with white spirit or kerosene, then replace the previously removed parts, including plugs, plugs, covers, etc.
This article indicates only the key points in the anti-corrosion treatment of VAZ bodies. In the process, each of the models may have its own specific nuances. But in general, any car enthusiast can perform such body treatment.
Selection of required materials
Now you should begin selecting the necessary materials to make the type of sink in question with your own hands. First you will need to select and purchase a number of parts. Purchasing a pump will take up a large part of the amount for the purchase of components. But this element can probably be called the most important in this device. The emphasis should be on models that have high performance. Specifically for high-pressure washing, the best solutions are those that can develop pressure up to 110-190 bar. To create pistons, durable solutions such as ceramic should be used. For block heads – brass. And a large supporting area should fall on the special inserts of the crank-type system.
The next point is the selection of an electric motor. It is better to take a single-phase option if the sink will be used in a domestic environment. Connecting to the electrical network will increase the efficiency of such equipment. You will also need to have capacitors and a single-stage gearbox on hand. This is not to say that a homemade sink cannot do without these components, but if you want to extend its service life, then these parts will definitely not be superfluous.
An element such as a coupling will also be needed. Its main purpose will be to connect the motor to the pump. It must be soft because it must compensate for various types of discrepancies. In addition, it can be used instead of a fuse if there are any problems with the gearbox or pumping equipment. Another necessary element, which neither a sink made from a compressor nor a solution made from a high-pressure fuel pump can do without, is a water container. A certain volume of water will ensure that the pumping equipment operates evenly.
Other parts needing attention
In order for a homemade high pressure washer to be assembled correctly with your own hands, you will also need other components.
Additional items:
- filter element - a fine mesh that prevents the entry of dirt particles and debris;
- capacitor, single-stage gearbox - optional components, but they make it easier to start, improve the quality of work, and productivity;
- compressor – can be used as a pump, the basis for a car wash, greatly simplifying assembly;
- performance regulator, unloading valve - parts that ensure safety and efficient operation;
- clamps or hydraulic sealing - will make the connections airtight;
- elements in contact with water are selected from corrosion-resistant alloys.
Having completed the collection of spare parts, you can begin fastening the elements and installing them on the frame. It is important to maintain the ability to repair equipment by more often using threaded connections.
Drying the engine after washing
You cannot start the engine immediately after washing, as the engine needs to be dried. Regular paper towels work well for drying the unit. With their help, it is necessary to remove water as efficiently as possible. After this, you can remove the protection in the form of bags and foil. Make sure that no moisture gets on the protected elements. If drops of water are found on connectors and electrical contacts, they should also be thoroughly dried.
Finally, we add that if corrosion and oxidation of the battery contacts is detected, you can use a solution of baking soda and water in a 1:1 ratio. This solution is applied with a toothbrush and allows you to clean the indicated parts. Then you need to wipe the cleaning areas with a cloth soaked in water, after which you will need to completely remove any remaining moisture using a dry paper towel or rag.

How to wash your car
It is strictly prohibited to use household cleaning products to wash your car. Do not use laundry soap or detergents for cleaning dishes, tiles, and glass. To wash your car, choose a special detergent - car shampoo. It effectively removes dirt and does not damage the paintwork. Dry cleaning shampoo is chosen when washing a car without using water. EcoDux is especially popular.
Hard-to-remove carbon deposits accumulate inside the wheels, which cannot be cleaned off with simple car shampoo. For this procedure, special chemical compounds from the car cosmetics department are used. These are substances that contain active elements to eliminate oil stains, rust and carbon deposits. Among them, “Cleanol Wheel” and “DISCO” are popular.
Tires and wheels are cleaned with a separate rag, since these parts are contaminated with sand, dust, and metal particles from the brake pads. Dirt is removed with a soft, non-abrasive cloth. A vacuum cleaner helps to remove uncleaned residues from disks.
How not to wash the engine compartment of a car
First, let's talk about negative examples that can often be observed among careless motorists, that is, about what should not be done.
You cannot mercilessly spray the entire engine compartment with the product.
, especially under high pressure, because the drug gets into places where it shouldn’t go: on the generator, wiring and other components of electrical equipment - these parts do not tolerate water and chemical solutions.
Do not wash off the applied product and dirt with too powerful a stream of water.
Water has a pervasive property, which in this case can only harm the car. At the same time, do not forget that the heat and noise insulation on the inner surface of the hood is quite fragile, and therefore a powerful jet of water can tear it.
You cannot wash the area under the hood outside during the cold season.
Water can get into the moving parts of the engine and freeze. For example, if the starter freezes, turning the key can burn the windings of its motor and also burn the battery.
Do not start washing under the hood without first removing large debris from there.
eg dry leaves. Otherwise, the drainage holes for draining water may become clogged, and then during the next wash or rain, many important parts may end up in the “aquarium”.
Now let's talk about what can and should be done when washing the engine compartment. As already mentioned, dirty parts under the hood of a car cannot be cleaned with a damp cloth. To do this you will need special tools and equipment.
Principle of operation
If we talk about the principle of operation, then any sink or mini-wash has two main elements around which the work is built - a pump and an electric motor. The power and performance of these components will determine the impact force of the water jet, which is used for hydrodynamic cleaning of various surfaces. Please note that excessive load on the engine can cause the washer to fail or overheat.
To prevent this, a forced-type cooling mechanism is usually installed.
As a rule, we are talking about a pair of fans. The first blows on the motor stator, and the second is mounted on the shaft and releases hot air from the housing. If the temperature rises above a critical level, the device turns off thanks to a temperature sensor. A pump with a cylinder block and a group of pistons is also responsible for the force of the water jet.
That is, to put it simply, the liquid is transported through tubes into the internal circuit, where under the action of the pump its speed and pressure increase. After this, the water leaves the device through a special valve, which is called a gun because of its shape. The pressure in a washer of this type is about 100 atmospheres, although everything will depend on the specific device.
How to properly wash a car engine at home
The process of washing a car engine can be divided into two main stages: preparatory work and the washing itself. The final result directly depends on the thoroughness of each operation.
Preparing the engine for washing
Before you spray the engine compartment with a generous layer of cleaning solution, there are several important preparatory procedures that need to be completed. At first glance, they seem unnecessary and time-consuming, but the benefits of these operations will be enormous, because after washing you will not have to dry wiring, electrical appliances and other parts for a long time.
- First of all, you need to disconnect the negative terminal from the battery.
- Wiring areas with joints, sensors, generator and connectors should be protected from moisture using plastic film and tape.
- It is highly advisable to remove the engine crankcase and gearbox protection for free access to the lower part of the engine.
If necessary, you also need to disconnect those components and parts that interfere with access to the engine.
