2. Be sure to choose products with trademark registration, patent right and quality inspection report, and you can find their registration numbers online. Never buy three-no products, and your rights and interests can't be guaranteed afterwards.
3. Try to choose brand products that have been put on the market earlier and whose quality has been tested by the market for many years. He is the crystallization of cleaning experience.
4. Choose products with reasonable cost performance. We must change the misunderstanding that the price is cheap. The materials selected for low-end products must be cheap, so the quality and durability of such products cannot be guaranteed. It seems that the principle is similar, but the parameter matching between components is unreasonable, and the cleaning effect is difficult to guarantee.
5. The safety, durability and cleaning effect of geothermal cleaning machine are the most important parameters. Don't be fooled by business style, power and digital automation. All the power of the pulse machine is the power of several watts of electromagnetic valve, so it is difficult to ensure the cleaning effect of the automatic cleaning machine with one frequency, because the geothermal pipeline is long and short, and the scale and deposit are different, so the pulse frequency must be controllable rather than automatic.
6, must choose a brand with after-sales service commitment and service network, the existing pulse machine in the process of use because of the machine itself and the operator's factors will have such and such problems, should be timely guidance and maintenance, in the shortest possible time, anytime, anywhere near the solution, without affecting the cleaning construction. What's the price of this cleaning machine?
The price of each brand is different.
It is also recommended to ask in a physical store and shop around, 100-200.
