High-pressure washer is a mobile analog of a car wash. Such equipment is used to thoroughly wash the car, yard, utility room, cattle pen or garage. Powerful water jet qualitatively cleans the carpet. High-pressure washers differ in purpose and parameters of work.

What is a high-pressure washer

The equipment consists of a hose for supplying water to the device, a motor, a pump, a hose with a washing nozzle, a filter, a housing. The device is powered from the power grid through a wire, from a battery or a motor.

The apparatus is connected to a water supply or other water source. If it runs on a motor, it is started. If the washer is powered from the power grid, it is connected to it. A nozzle suitable for certain tasks is installed on the gun. The pump pumps water, high pressure is formed. The gun regulates the direction and supply of water.

How to choose a high-pressure washer

First of all, it is determined with what class of equipment is needed:

• Household high-pressure washers are compact, work from the network or battery. The water pressure does not exceed 180 bar. They are used for washing a personal car, the facade of the house, the yard.
• Professional high-pressure washers are larger, give a more powerful water flow, operate on a gasoline engine. They are used in public utilities, car washes, construction sites and everywhere where it is required that the device works for a long time.

Pay attention to such characteristics of the high-pressure washer:

• Whether there is a voltage stabilizer. It is necessary to protect the electric motor from current fluctuations.
• The length of the hose affects the convenience of working with the device. For washing a car, a hose length of 4 m is sufficient. If you need to use the washer for garden work, on the construction site, it is better to choose a model with a hose length of 7 m.
• The pressure of the washer should be at least 130 bar.
• The productivity of such equipment indicates how much water is spent per hour. Household sinks spend 600 liters of water, professional devices - 2-3 times more because of the difference in the force of pressure.
• If you need a lush and abundant foam, choose a washer with a foam nozzle, which is put on the gun. Less foam in devices with a separate hose for detergents.
• The water intake function comes in handy to draw liquid not from the water supply, but from a body of water. For this purpose, the washer has a hose with a check valve. However, the distance from the water level to the place where the hose bends against the edge of the tank or the shore should be no more than half a meter.
• The plastic housing material makes the unit lighter and cheaper. Aluminum or brass housing is stronger, heavier and more expensive.
• If you are going to use the washer for different tasks, it is important that the set had different nozzles: fan, rotary, for cleaning pipes, etc., it is more practical if the apparatus has different nozzles.
• It is more practical if the device has a reusable filter. It can be cleaned. It is cheaper than replacing it with a new one.
• Water heating can be up to 40 or 60 degrees.

It is important to choose a high-pressure washer from a reliable manufacturer. You can familiarize yourself with the official website of the company, with reviews on the Internet about products and a particular model.
