The main function of the car washer (pressure washer) is the spraying of conveyors, washing the car, washing industrial dirt. But besides that, it also has many additional functions such as: cleaning moss on brick yard, cleaning path, cleaning paint on wall, spraying herbicide…. Therefore, each different job requires a different type of pressure washer machine.
Before choosing to buy a pressure washer, you should think about what kind of work you do with it. If you choose to buy indiscriminately you can spend more money without using all the features and accessories of the machine. Considering the work that requires the use of a pressure jet will make it easier for you to choose the right machine. I will suggest you a few small details so you can choose the best pressure washer.
SOME THINGS YOU NEED TO KNOW WHEN CHOOSE A CAR WASHER
The car washer is no longer a strange sanitary device for those who own a motorcycle, a car, or even a bicycle. But to choose to buy a good car wash and suitable for the car they are running, not everyone knows. The question is: What type of pressure injection machine is suitable for bicycle washing, which machine is suitable for motorbike and which machine for washing car? Should you choose an electric, diesel or engine washer? Choose hot water jet or cold water jet? …
1. Things to know before choosing to buy a car washer:
1.1 How does the car washer (pressure sprayer) work?
Most pressure injection machines work on the same principle. From pressure injection machines using gasoline, diesel to electricity. However, there is a difference in the durability and weak strength of the engine in each type of machine. Accordingly, pressure washers using electric engines will not be as strong as pressure injection machines using gasoline and diesel engines. But the advantage is convenience and can be used anywhere with electricity.
1.2 What is the difference between an industrial car washer and a home car washer?
The amount of sprayed water is inversely proportional to the pressure, which means: the same engine power, if the water flow is large, the water pressure will be reduced, and as an industrial car washer, the water consumption will be more than the family car washes. And if the amount of water is too little (means the high water pressure of the family car washer), when washing a large car + many cars (for service) it will take a long time and not clean, because the pressure at the nozzle maybe 100 => 150 bar, but when the water reaches the object to be washed, it will be reduced very quickly due to the small amount of water. With industrial car washers, the water pressure only needs to reach over 60 bar is OK!
In addition, family car washers and professional car washers differ in that:
Household car washers usually have a rotating disc-type pump head, an aluminum head, with a lifespan of only 1/3 of a piston pump head. So, when using this machine for service purposes, continuous and regular operation, the machine can only run for a short time => Failure.
Professional car washer is constructed by piston pump head, withstands high pressure to super high pressure, so it can be operated with maximum frequency, for service use.
1.3 Ratings of PSI and GPM
– HP (Horsepower): Power of the engine. This rating is important as it is related to the volume and pressure of the pump. (This is the specification used in the engine pressure injection, using gasoline or oil). An electric motor is measured in amperage (A), or HP, or AMPS.
– PSI: water pressure (the greater the psi, the faster and more effective cleaning speed)
– GPM: Volume of water available for cleaning
CPU (or CU, CP): This is the most important specification for pressure injector rating, but also one of the most confusing. To determine the CPU of a pressure injector, you do the calculation: PSI x GPM.

2. Features and options
When buying a pressure washer, consider the following options and features:
2.1 Check the water flow rate. Municipal water usually works well, but well water can cause problems.
2.2 Check brush, nozzles and refer to the appropriate cleaning method for the job, the surface to be cleaned.
2.3 Check the pressure injection machine accessories included and can be purchased if necessary. There are many attachments designed for specific jobs: rotating brush, nozzle, patio …
2.4 Find a quick search of accessories that help with car wash. This will allow you to clean the car more easily and quickly.
2.5 Consider and choose an accessory that comes with a multimodal or a multi-purpose pressure injector (like 3-in-1). Check out the attached accessories and machine features designed to handle a wide range of cleaning tasks. Surface cleaners used to clean large surfaces are done 10 times faster than a standard spray application.
2.6 If your cleaning needs are higher consider and choose to purchase a pressure injector that includes fuel injection electronics (EFI). This feature will help the cleaning job 50% faster than conventional machines, and better fuel economy.
2.7 Consider and select products certified by the Pressure Spray Manufacturers’ Association such as Lavor and Kärcher series.
Before starting any cleaning job, always remember to read the instructions that came with the pressure sprayer. When performing outdoor cleaning tasks, many manufacturers recommend wearing goggles, work gloves, and ear protection. The cleaning surface can become slippery when wet, so wear shoes with non-slip soles. You may also need to wear waterproof clothing or a raincoat to keep your clothes dry.
The pressure sprayer will become hot during operation, so be careful when handling. Also, make sure that the engine has completely cooled down before storing. Also remember never to operate a diesel or petroleum gas injection indoors.
