How to choose a pressure washer and what to look for

February 04, 2021

When choosing a high- pressure washer, you should pay attention to the following characteristic - washing pressure. The pressure that the device generates is the main indicator of efficiency. The higher the better.

Pressure washers are divided into two groups:

Household - pressure from 20 to 150 bar;
Industrial - pressure from 200 bar and above.

Please note! A high-pressure washer with a capacity of 100 to 160 bar is suitable for washing a car. It is uneconomical and impractical to use more powerful devices for this purpose, as the car's paintwork may be damaged. Less powerful devices may not cope with their task.

Performance - this is the amount of water consumed during continuous operation. Usually, one hour of operation is taken as an hour. For household machines, this is 350-500 liters per hour, and for industrial ones from 600 to 1000 liters.

Water suction function - washing machines are connected to the water supply system. Some models can receive or suck water. This function is very convenient in the absence of a water supply, as it allows you to use water from reservoirs, containers, etc.

The material of the pump casing and its internal parts - the “heart” of the device is its pump, since the operation of the device depends on the quality of this unit. Plastic pumps are cheaper, but less reliable, and in the event of a breakdown, as a rule, they cannot be repaired and will have to be completely replaced. For frequent and long-term use of the device, it is better to choose a device that will have a brass or aluminum pump.

Please note! Metal pumps use valves made of steel or metal-ceramics. This significantly increases the life of the device and improves its performance.

Hose length - The convenience of using a pressure washer depends on the length of the hose. 4 meters will be enough to wash a car, and 8 meters to wash the facade of a building. For greater convenience, some models have special hose nozzles.

Additional nozzles - To increase the efficiency of the machine, there is a wide selection of additional attachments:

Rotating nozzles;
Pipe cleaning nozzle;
Rotating nozzle brushes;
Cloudy brushes;
Convenient nozzles for hard-to-reach places.
