High pressure washer is a special equipment for cleaning cars and various surfaces. The range from well-known manufacturers includes dozens of different models. They differ in functionality, technical parameters and a set of accessories. To simplify the choice of a suitable unit, it is worth deciding on the necessary options, as well as comparing the characteristics of several models.

When choosing a unit, you should evaluate its performance and functionality..

Type of water intake

Most compact sinks take water from the water supply and a separate tank. Some models cannot be connected to the water supply. It should be borne in mind that when liquid is taken from a separate container, the outlet pressure will be much lower.

For example, if the maximum pressure of the unit is 120 bar, when water is taken from the tank, it is reduced to 100 bar. This leads to difficulties when washing the surface.

Use this method only if it is not possible to connect the device to the water supply. In this case, the tank must be placed higher to ensure the flow of water into the device by gravity. Due to this, the load on the pump will slightly decrease and the outlet pressure will increase.

Max pressure

One of the main parameters that determine the ability of the unit to cope with dried spots. Mini-sinks with a pressure of less than 120 bar will not be able to wash old dirt. Units with a pressure of 150 bar will cope with this task, but they must be used carefully. This is due to the fact that under such pressure it is possible to damage the paintwork.

For domestic use, pressure washers from 120 to 150 bar are suitable. Models in which this parameter can be adjusted are especially convenient. It should be borne in mind that even a professional high pressure washer will not clean the surface if a low-quality shampoo is used.

Maximum performance

The parameter determines how quickly the unit will cope with its task. The higher the performance, the wider the jet and the greater the contact with the surface to be cleaned.

When choosing two models with similar characteristics, you should give preference to the one with higher performance.

Washing power

Power determines the performance and maximum pressure of the device. But, choosing a unit solely on this parameter is not very convenient.

It is worth paying attention to the previous two indicators. Knowing the power is necessary to check the honesty of the manufacturer. If the actual power is lower, then these parameters are too high.

Housing material

Plastic is often used in household appliances. It is an inexpensive and lightweight material. But, if it breaks, you will have to completely replace the part. Plastic parts are supplied with mid-level models.

Wash class

Sinks are divided into household and professional. The former are suitable for working on a personal plot, washing the facade of a house, a car and other personal matters. They are compact and mobile. Designed for small loads, since the pressure in them is not more than 180 bar.

In professional devices, pressure is higher, as is productivity and the ability to work for a long time without interruption. Such models are equipped with a powerful gasoline engine. They are used for cleaning at industrial enterprises, in construction sites, etc.

Power type

Washers only work when connected to a power source. It can be a cigarette lighter in a car, a one- or three-phase electrical network, or liquid fuel. For example, petrol or diesel.

Mains voltage

Different types of sinks require different power sources. Some are connected to a 12 V network (cigarette lighter in a car), others to a 220 or 230 V network in a household electrical network. Professional units for industrial use operate when connected to a 380 or 400 V network.

Water consumption

The rate of water consumption affects the performance of the device. Most models have the ability to adjust the flow. The maximum flow rate is indicated in the instructions for the device. The higher the indicator, the easier it is to wash the surface from old contaminants and process a large area.

Detergent use

The function is implemented in different ways. In the first case, the sink is equipped with a special tank where you need to pour the product. It is dosed and mixed with water. In some appliances, water is mixed with detergent as it exits the washer gun. Abundant foam is formed, with the help of which it is easier to wash the surface.

Additional functions

High pressure limits the continuous operation of the unit. Some models are equipped with a special sensor that protects the device from damage. It stops the device at a certain point so that the engine does not overheat.
