1.Depending on usage:

General high-pressure cleaners can be divided into two types: household and professional. If you use the cleaning machine less than 50 hours a year, you only need to buy a household cleaning machine. The price is relatively cheaper, the weight is lighter, the material is simple and not heat-resistant. If the use time is more than 100 hours, you should consider a professional high-pressure cleaner, which is larger in size and made of durable materials such as copper alloy pump heads and stainless steel valves. The price is of course much more expensive. Therefore, how to choose should depend on consumer needs.

2. Depends on hot and cold water needs:

High-pressure cleaners can also be divided into hot water and cold water types depending on the requirements of the occasion. Generally, most of the ones on the market are cold water type, which can be used by injecting normal temperature water from the faucet; but some business places need to be washed with hot water. At this time, it is especially necessary to purchase a hot water type high-pressure washer. If you rashly use the cold water type to inject hot water, the internal parts, including the water pump, will be damaged very quickly, and the gain will not be worth the loss.

A heating device is added to the hot water cleaning machine, and a combustion cylinder is usually used to heat the water. Using hot water for cleaning can quickly wash away a large amount of dirt and oil stains that are difficult to wash away with cold water, greatly improving cleaning efficiency. However, due to the high price and high operating cost of hot water cleaning machines (because they use diesel), most users may choose ordinary cold water high-pressure cleaning machines; of course, in order to improve cleaning efficiency and effectiveness, many professional customers will choose hot water cleaning machines.

3. Also choose a nozzle:

Different nozzles produce different cleaning effects. For example, the circular water column nozzle can increase cleaning efficiency, the fan-shaped nozzle can rotate the nozzle as a low-pressure spray (can spray soapy water) and high-pressure fan-shaped water column, and the low-pressure brush head can spray low-pressure water for gentle scrubbing, etc. Some of these nozzles will come with a gift, and some can be purchased by yourself. You should make a good selection based on your needs when purchasing.

4. Select a merchant

There are many brands of cleaning machines on the market. Imported ones are 1-2 times more expensive than domestic ones, or even more. You should choose according to your actual needs and budget. Usually imported equipment has new technology and has advantages in durability and efficiency compared with domestic equipment, but its price is also much higher and maintenance costs are 2-3 times higher than domestic equipment. After choosing a brand to use, you should also pay attention to choosing a merchant.
