The high pressure washer is a machine that makes the high pressure piston pump produce high pressure water to wash the surface of the object through the power device. It can remove dirt, wash away, to achieve the purpose of cleaning the surface of the object. This cleaning method has no special requirements on the material, characteristics, shape and scale species of the equipment, but only requires direct exposure, so it is widely used. Because it is the use of high pressure water column to clean dirt, so high pressure cleaning is also recognized as one of the scientific, economic, environmental protection cleaning ways. It can be divided into cold water high pressure washer, hot water high pressure washer, motor driven high pressure washer, gasoline engine driven high pressure washer, etc. General pressure washers can be divided into household and use two kinds. Only buy a home washer if you use it for less than 50 hours a year. The price is relatively cheap, the weight is light, the material is simple and heat resistant. If the use time is more than 100 hours, it is necessary to consider the use of high pressure cleaning machine. The volume is larger, the material is made of copper alloy pump head, non-steel valve and other durable materials, and the price is of course much more expensive. So how to choose, should be based on consumer needs.
 
According to the requirements of the occasion, the pressure washer can also be divided into hot water and cold water and steam. Generally, most of the cold water type on the market can be used by injecting water into the faucet at room temperature; But some business places need to be washed with hot water, which is not conducive to sewage discharge and even need to use high pressure steam cleaning machine, then it is necessary to buy a special cleaning machine, if you use cold water injection of hot water, the internal parts including the pump will soon be damaged, more than worth the loss. Also choose the nozzle, different nozzle caused by the cleaning effect is different. For example, the circular water nozzle can increase the cleaning efficiency, the fan nozzle can rotate the nozzle as a low pressure spray (can spray soapy water) and high pressure fan type water, the low pressure brush head can spray low pressure water gently scrub and so on.
 
All kinds of motor vehicles, engineering vehicles, engineering machinery and agricultural machinery supporting products cleaning and maintenance, such as washing cars, bulldozers, concrete mixers, tractors, etc. It is also an ideal cleaning tool for personal and small vehicle maintenance units to clean cars and motorcycles.  

So what is the advantage of the cleaning efficiency and cleaning effect of the high pressure washer over the traditional cleaning way?

1. The high pressure cleaning equipment is intelligent, easy to operate and safe.
2. High pressure cleaning equipment is not limited by space.
3. The high pressure cleaning equipment can be cleaned with various cleaning mechanisms without dismantling the machine.
4. High pressure cleaning equipment without chemical reagents, no pollution.
5. High pressure cleaning equipment has high cleaning efficiency and full functions.
 
When choosing high pressure cleaning equipment, the main parameters are the determination of pressure, flow rate and power. In addition, the choice of cleaning institutions is also very important. Cleaning nozzle selected will also achieve twice the result with half the effort.
 
There are many types of cleaning machine nozzles, such as general column nozzles, fan nozzles of different angles, pipe cleaning nozzles, mouse nozzles, mines, single hole rotating nozzles, porous rotating nozzles, three-dimensional rotating nozzles, hair pulling nozzles, dredging nozzles and so on.
 
The type of high-pressure cleaning nozzle configured for different uses is also different.
