(20 ratings, average: 4,13 out of 5)

Many car enthusiasts today prefer car washes high pressure when washing a car with a regular rag. The fact is that washing provides more gentle cleaning of the paintwork. There is no need to wash the car with a sponge or cloth. A directed jet of water allows you to not only knock dust off the body, but also eliminate enough heavy pollution. Considering that there is plenty of dirt on our roads at any time of the year, we can safely talk about saving money when operating such devices.

Unfortunately, good car washes they are not cheap. Not all car enthusiasts can afford to buy them. Therefore, creating your own high-pressure washer seems to be quite an interesting option.

How to choose a mini washer?

All mini-washes should be divided into 2 groups: professional and household.

Professional car washes

Professional devices are characterized by increased reliability and excellent performance. But they are not available to everyone, as they are very expensive. And there is no need to talk about their compactness. The average weight of such devices is close to 100 kg. Even though they are mounted on wheels, they are not at all easy to move. The main advantage of professional AEDs lies in their characteristics:

Professional car washes can work without interruption for a long time.

Despite the attractive functionality, such devices are a specific product, and ordinary car enthusiasts almost never buy them. To ordinary people household mini-washers are sufficient.

Household AEDs

Household mini-washers can be used not only for washing car bodies, but also for solving the following problems:

  • Clearing clogged drains.
  • Cleaning garden tools.
  • Cleaning local area from construction waste.
  • Cleaning garden paths.
  • Cleaning walls, house facades and fences.

All household high-pressure car washes are divided into subgroups according to the following criteria: water temperature, type of power supply, power.

Household mini-washers can receive heated water from outside or heat it themselves. Unheated devices are slightly less expensive than heated devices.

Depending on the type of power supply, household high-pressure car washes come in petrol and electric.

Devices with gasoline engines considered close to professional car washes. That's why they cost accordingly. The cheapest car wash with gasoline engine will cost the buyer $600. The most expensive one sells for $5,000. It is not surprising that they are not popular in our country.

Domestic high pressure car washes With electric motor the choice of a simple car enthusiast. Based on their power, such devices can be divided into 3 groups:

Choosing a mini-wash

When choosing a household AED, The following parameters should be taken into account:

  1. Performance.
  2. Pressure.
  3. Pump material.

Plastic pumps do not last long and are installed in inexpensive, low-performance devices that can be used to wash a bicycle, motorcycle or garden cart. It is not enough to wash a car. More precisely, with the help of such a car wash you can wash your car, but it will take a lot of time due to its low productivity.

The car can be easily washed using AED with brass or silumin pump. This household appliances middle class. Their performance and pressure are sufficient to wash any passenger car. Essentially this is the best choice for household use.

Of course, if a car enthusiast has extra money, he can buy a high-class household high-pressure car wash, but for the average car enthusiast this is a luxury.

If you don’t have the money to buy an AED or simply don’t want to part with a large sum, then you can make a high-pressure car wash with your own hands.

First you need to prepare necessary details. First of all, choose a pump. It must meet the following requirements:

To secure the pump in the housing of a homemade AED, you will need a coupling. It is best to choose a soft model, as it will compensate for the misalignment of the shafts along the axes.

Let's not forget about water containers. This could be a large canister or barrel. It is advisable that the container has water supply. Be sure to install a filter at the outlet of the container. It will protect the pump from sand and other contaminants.

High pressure hose with a gun equipped with a nozzle that creates a working jet.

We hide the pump in a separate container and connect it through fittings to the main container with water and a hose with a gun. At the outlet of the pump we install a regulator with a closed By - pass.

Water container and pump container can be installed on a frame made of lightweight hollow pipes. For ease of use, the frame itself can be placed on support wheels.

All that remains is to supply power to the pump, which will begin pumping water from the main container through a hose with a gun.

Assembling a mini-wash with your own hands, do not forget to ground the device. Before starting, make sure that all electrical components of the washer are properly isolated from water.

During operation homemade apparatus The AED should regularly check the security of all fasteners and tighten them if necessary. Try not to load the device to the maximum, as this will lead to rapid wear of the pump. In addition, excessive pressure can easily damage paintwork body

As you can see, do homemade karcher not difficult. But although such a device will be mobile, it can still be used only where there is an electrical network of 220 volts. What if you need to wash your car while on the road? To do this, you can make a mini Karcher powered by a cigarette lighter.

To create it we will need:

We make a hole in the lid of the canister and insert the fungus from the wheel into it. The entire structure is reliably sealed.

We also make a hole in the bottom of the canister and install a fitting to which we attach a hose with a gun at the end. We connect the hose from the compressor to the fungus in the lid.

The simplest sink is ready for use. All that remains is to pour water into the canister, close the lid and turn on the compressor. He will provide required pressure streams of water coming out of the gun.

Of course, this mini Karcher cannot boast of high pressure, but it is quite enough to knock down road dust or wash off detergent from the car body while parked.

A high-pressure washer is a convenient device that allows you to easily wash your car, as well as other surfaces in your home. Thanks to the strong water pressure, such devices are able to clean even heavily soiled surfaces without the use of detergents.

Such devices are usually installed in car washes and cost a lot of money. The Karcher high pressure washer has deservedly gained popularity, but not everyone can buy it. Therefore, for use at home, you can make a car wash with your own hands. - an excellent alternative to professional ones, which you can assemble yourself from improvised means.

To make a Karcher high pressure washer you need to find suitable materials. You can use scrap items or buy new ones at the store. So, to create a mini-wash you will need:


How the device works

It will work on the principle of conventional car washes. The water is supplied through a rubberized hose under high pressure. Air is pumped into a container with water by a car pump, which creates a overpressure. Water is pressurized to the outside and released when the trigger of the watering gun is pulled. Thanks to the strong water pressure, a car wash can clean any surface.

IN in this case the pump is used solely to pump air into the tank. You can replace the constant use of a pump by installing a pump that will allow you to increase the pressure manually. Also an alternative to automobile pumps are plunger pumps.

Plunger pumps - modern devices, which are classified as metering-type hydraulic devices. The plunger pump independently mixes water in the selected proportions, detergents and delivers the mixture under high pressure. The disadvantage of installing such a pump is the excess final weight of the car wash.

How to assemble a car wash with your own hands

Initially, you need to prepare a water tank. To do this using sharp knife It is necessary to cut a hole in the lid of the canister, which will be narrower in diameter than the nipple. After this, a nipple is threaded through the inside of the lid.

Advice : If the hole is larger than required, the gaps must be additionally sealed.

Through the nipple in the lid, the pump will pump air into the tank, and will also fill with water and detergents.

Next, you need to prepare a system for connecting the canister to the watering gun. To do this, you need to cut a hole in the bottom of the canister close in diameter to the coupling. The coupling is attached from the inside of the canister; you can wind it using a piece of wire. After threading the hose connector, sealant must be applied around the circumference. A fitting is also attached to the coupling.

After the sealant has dried, you can begin preparing the sink for use. To do this, plug the fitting with your finger and pour water into the canister. You can also add any detergents to the tank (specialized detergents for cars or household chemicals). The nipple must be connected to a car pump and gradually inflate the canister with air. While performing this action, you need to ensure that the canister does not inflate too much. If it was decided to install a plunger pump or pump, then they are attached to the fitting using connecting hoses.

Having completed these steps, a rubber hose is connected to the fitting, at the end of which a watering gun should be attached.

Advice : You can check the correct assembly by pressing the trigger of the gun. If, as a result, water begins to flow from the gun with strong pressure, then the device is assembled correctly. If this does not happen, then the canister is leaking air and you need to check all connections again and, if necessary, treat them with sealant.

Despite the wide range of services, it is not always possible to wash your car at a car wash. Sometimes you don’t need to wash your car urgently; you just need to wash the lights and windows or contaminated areas after parking the car under trees. Sometimes all it takes is a wet rag, but sometimes a bucket of water is not enough. Anyone who has worked with portable mini car washes from Karcher knows that water consumption when washing a car is much lower. The master's secret offers the design of a portable sink, let's call it low pressure. But this wash will allow, in the absence of running water, to bring self-washing of a car closer to the civilized method and sharply reduce water consumption.

How to make a homemade Karcher for a car

The design of the sink is extremely simple; to create it you will need plastic container with a tight screw cap with a capacity of 4 - 20 liters (canisters for storing gasoline are very suitable), a spray gun, a set of quick-release hose connectors (3/4 threaded fitting, two connectors for the hose diameter, adapter coupling 3/4 - 1/2) , a car nipple for tubeless tires and a piece of hose 1.5 - 2.5 meters long. The tool you need is a knife with a sharp end, silicone sealant And car pump or compressor.

The operating principle of a mini washer. A hose with a watering gun is connected to the bottom of the water tank. A car nipple - a fungus - is built into the filler neck. Fill the container with water to 3/4 - 4/5 of the volume, screw on the lid and pump the container with air. The system creates excess pressure under the influence of which water will flow out when the trigger of the gun is pressed.

The assembly diagram for a mini sink should not cause any difficulties if executed carefully.

1. Using the sharp end of a knife, slowly and carefully form a hole in the lid of the container, slightly smaller than the fitting diameter of the nipple.

2. C inside insert the nipple. Tests have shown that the nipple becomes tight and does not require additional sealing.

Nipple hole The nipple is inserted into the cover

3. At the bottom of a flat canister without protrusions or seams, slowly and carefully make a hole for the coupling.

4. Using a wire from inside the canister, insert the coupling into the hole.

5. Apply silicone sealant to the joint and screw the fitting to the coupling. We are waiting for the sealant to harden.

Sealant applied

6. Screw on the lid. We are waiting for the sealant to harden. We connect the pump. We plug the fitting with our finger and increase the pressure in the container; if everything is done carefully, the container will hold pressure.

7. We equip the hose with connectors. We connect one end of the hose to the canister, and the other to the watering gun.

8. Fill the canister 3/4 - 4/5 with water and pump air inside. We do not pump the canister too much; it expands under pressure (becomes more round). Don't get carried away with increasing pressure. When using large-volume canisters, it will be necessary to provide clamps to prevent excessive inflation of the container.

Connectors installed

Today, you no longer need energy and time to fight dried-on dirt and dust that has clogged up in secluded corners, because new models appear on the market every year high pressure washers. 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.

Companies leading in the production of high pressure washers - German companies Bosch, Karcher (hence the second name for the sink - Karcher) and Elitech. The average price of these sinks on the market starts from 10,000 rubles. Inexpensive car washes cannot be used for more than one car per day, and the capabilities of the most expensive models limited to seven cars.

Washing device

The main component of the sink (or Karcher) is the engine, which creates required pressure water. A pump or motor will do (you don’t have to buy a new one, take a working one from an old car), the motor is built into the body of the sink and must be connected to a power source. For the body of the sink (body), choose durable material, thick plastic or metal. Even if you purchase a wear-resistant case, it is better not to use the sink for more than three hours at a time. This will put the washer out of action soon.
Hose attachments are available to facilitate the cleaning process - brushes of varying hardness, soft rollers, standard sprayers. If you purchase a couple of attachments, you can expand the functions of your sink by using it as an automatic mop or steam cleaner (you need to equip the sink with a heater).

Internal pressure

The higher the pressure inside the housing, the stronger the stream of water gushing from the hose, which means the dirt comes off easier. Set the pressure carefully, because water can simply break a fragile car part or glass and leave dents. Manufacturers set the pressure at 150-170 bar, but 100 bar is enough to clean the car.
If the contamination cannot be cleaned with a jet of water, purchase a special nozzle for the hose, a turbo cutter. It will help wash tires, wheels, and remove dirt accumulated in the cracks. You can use the mini-wash both outside and inside the car. If you are using a turbo cutter, you will need a pressure of 160 bar.

Electric pump

Before purchasing and using a pump when designing a sink, read how to choose the right device.
The material of the pump determines its wear resistance. A bad option is a plastic pump; it will soon fail if you use it for more than 20 minutes at a time. Expensive but reliable pumps are made of brass because it does not corrode. These pumps are rarely found in commercial car washes.

How to use the mini-wash

To wash worked properly, follow these recommendations.

  • Be sure to check the operation of the washer before you start using it, this will save your time and health.
  • Clean and change the filter installed in the car wash after each use.
  • If the washer uses electricity to operate and the source is unstable, provide it with a battery.
  • Do not let children use the sink.
  • If repairs are necessary, do not hesitate to carry them out. Replace damaged sink components.
  • Update the device gaskets.
  • Protect your sink from temperature changes.

How to make a Karcher yourself

Although car washes have achieved widespread use, they come at a high price. So, if you want to do the sink yourself, you will be needed:

  • canister;
  • irrigation hose with gun;
  • pump;
  • union;
  • canister lid;
  • tubeless wheel fungus;
  • rubber gasket;
  • coupling.

These are the components of the future car wash. Materials that will come in handy during the manufacturing process:

  • drill;
  • sealant.

First stage. Selection of components.

The required volume of the canister depends on you and the purposes for which you will use the washer: a five-liter canister is enough for a passenger car. Drivers carry a car wash in their luggage, so choose a body based on both volume and dimensions.
The irrigation hose must be strong and flexible and should not be twisted or broken. Hoses with nylon braid are considered durable. A hose consisting of several layers is more reliable. Don't skimp on this component. The only requirement for the gun is that it must hold tightly to the hose.


The pump can be foot-operated or automatic. We won't need the high power of this pump, so don't buy an expensive one. Using an automatic pump is much more convenient than a foot pump, since you do not have to constantly drag the pump from place to place and do unnecessary work with your foot. However decisive role The cost of the pump plays a role, the automatic one is three times more expensive.
Choose the fitting and coupling at your discretion, the main thing is that they are in close contact with each other. It is preferable to purchase both the fitting and the coupling from the same material (plastic or metal).

Second phase. Preparing the canister.

Drill a hole in the canister that is the right size for your coupling. Insert a coupling with a screwed-in fitting into this hole. Secure the structure with sealant so that the coupling does not pop out during operation, and the required pressure is maintained in the canister.

Third stage. Cover assembly.

The lid needs to be strong, solid and suitable for the canister. To prevent air from escaping from the canister, attach a rubber gasket to the bottom of the lid. Then make a hole in it and insert the tubeless tire fungus into it.

Fourth stage. Assembly of the structure. Additional functions.

Screw the lid on the canister tightly, connect the cord from the pump to the fungus, attach the free edge of the hose to the hole made in the canister using a fitting. Homemade sink ready. The principle of operation of such a washer is simple: using a pump, air is pumped into a canister of water (the canister is not filled to the brim with water). Create pressure up to 0.3 bar or higher if your canister can handle it. Under the influence of pressure, water streams out of the gun when you press the handle.
If you will use the sink during the cold season, equip your sink with a special burner for heating the water. For these purposes, you will need a larger canister; it will lose mobility, but with the help hot water The car is cleaned of heavily dried dirt.


Provide a power source for the washer. If the washer runs on fuel (gasoline or diesel fuel), then there will be no problems with moving it. When planning an electric car wash, make sure you have a working and accessible source of electricity. In this case, you are unlikely to be able to freely transport the sink from place to place, but you will not have to spend money on expensive fuel.
Decide in advance what you are using the sink for. If you want to clean the windows of a house or the wheels of a car, then a compact, mobile washer on wheels and with a long hose will suit you. When using a sink on a production scale, you will not need its ability to move, so it is better to design a stationary sink. It connects directly to the water supply. If the need arises, set up automatic water supply to save money.
While you can save on water consumption, you cannot save on purchasing sink components. To prevent the item from becoming dirty after washing, purchase special filters. You don't need an expensive filter to purify the water to drinkable condition. A filter is needed to purify the water, at least from debris that will disable the sink.


You can even make money by designing a pressure washer if you open a car wash. The main thing is that the sink you make works. Using a car wash, you can clean bicycles, mopeds, cars, trucks and their components.

How to make a Karcher powered by a cigarette lighter

This sink design does not require any costs. Below are instructions for creating a more complex model:
Us you will need:

  • windshield washer motor;
  • irrigation hose with gun;
  • cigarette lighter (motor power supply), cigarette lighter plug;
  • two hoses 3 meters long, one hose must fit freely into the other;
  • corrugated hose with a diameter of 25-30 millimeters;
  • switch;
  • M8 bolt, washer and nut;
  • two plastic canisters(volume 10 liters);
  • 6 self-tapping screws;
  • two-wire electrical wire 5-7 meters long;
  • plastic sleeve;
  • power cable;
  • brush for washing a car.

Additional materials:

  • sealant;
  • drill.

First stage. Creating a hose.

We make a small hole in the bottom of one of the canisters. A thinner hose (up to 6 millimeters) and a two-core wire are placed inside a thick hose (diameter 10 millimeters or more). Then the hoses we have fastened are inserted into the opening of the canister. A plastic sleeve is inserted into the free end of the hose. Next, a thin hose is attached to the washer motor, and the wires are also connected to the motor.

Second phase. Creating a canister with a double bottom.

The second canister is cut approximately in the middle in order to subsequently make a second bottom with a shuttle out of it. The motor is fixed to the second bottom of the canister; for these purposes, a homemade clamp is used, which can be made from the remains of a cut canister. For this we need an M8 bolt and a little sealant.
The wires are also secured using self-tapping screws and sealant. Then they connect, again using self-tapping screws, the body of the structure: the second bottom and the hinged lid.

Third stage. Completion.

Using the power cord, the wires are connected to the cigarette lighter. A hole is made in the brush for the button, the switch is secured. The brush itself is mounted on the edge of the hose with a plastic sleeve. Use the attached diagrams in your work to better understand the text.

IN modern world Every family has a car, and not just one. Whether domestic or foreign, they all require constant care. A spare part has gone bad - you need to replace it, a tire has a flat - you need to pump it up, a window breaks - you need to put in a new one. And, of course, you definitely need to wash your car. Car washing is needed not only to keep the car clean. If you don't wash it, you can earn a fine from state safety inspectors. traffic. If you don’t wash it, the paint underneath the dirt stain will soon wear off and the body will begin to rust. If you do not wash the interior of your car, this can lead to various respiratory diseases and allergies.

Considering all the above nuances, the conclusion suggests itself: car washing is a mandatory procedure for any car.

Do-it-yourself homemade Karcher - the best option for washing a car

Choosing a method for washing your favorite car is up to the car owner himself. Someone can pick up a rag and a bucket, someone can go to a car wash. But perfect option- this is to make a homemade Karcher. It can be done by investing a certain amount of money, or it can be done from improvised means without investing in it.

Of course, a homemade Karcher will differ from a branded one, but it will fulfill its main purpose.

Advantages homemade device: low price, compactness, ability to wash dirt out of any crevice, autonomy, does not require electrical power, you can always take it with you.

Karcher?

There are many ways to do it.

First way. The main mechanism of the future Karcher is taken - the compressor. It can be taken from any equipment that is no longer used on the farm. The mechanism is connected to the fitting using a hose. A brush is taken and attached to it in order to regulate the power of water supply. The brush and tap are also attached using a hose. When fastening, you will need to use rubber gaskets, FUM tape, and hermetic glue. The hose, on the other hand, is fixed in a container into which more than ten liters of water can be poured. The simplest homemade Karcher compressor is ready for use. You can make a more automated method that will connect to the electrical outlet or the cigarette lighter in the car.

Second way. Take a canister into which you can pour more than twenty liters of water. A compressor from the car is connected to the inlet brass nipple from the tire. The hose is attached to a gun (you can purchase it at any garden store). The hose length is at least six meters. Diameter 16 mm. Rubber flaps, clamps and nuts are used for fastening.

The effectiveness of a homemade Karcher

The efficiency of a Karcher depends directly on the selected engine (compressor). It must supply high water pressure, otherwise the production of a home sink will run haywire. A homemade Karcher must consist of a durable body made of metal or thick plastic.

The choice of brush for the hose varies: from hard to soft. Rollers and sprayers can be used.

In any case, it is not advisable to use a homemade Karcher for more than three hours. Since this can lead to its early failure.
