1、 Look at technology;
The production technology of car washing machines is high and the production process is complex. In addition, the development of automobiles in China is relatively slow. Therefore, until around the 1990s, China's car washing machines were mainly imported machines. 2、 Check the accessories;
In addition to mature technology, the quality of a car wash machine also depends on its accessories, which are one of the basic guarantees for the quality of the car wash machine.
    3、 Observe the production process;
Having excellent accessories does not necessarily mean that high-quality car washing machines can be produced. The key to measuring the quality of a machine lies in its production process.
  4、 Check after-sales service;
As a product with high technological content, after-sales service is quite important. Many customers only buy machines from manufacturers that are close to them, citing the convenience of nearby maintenance. Actually, this is a misconception. Low machine failure rate and timely after-sales service are important.
  5、 Look at the comprehensive usage cost;
Purchasing a car wash machine should not only consider the machine price, but also take into account the overall operating cost of the machine, that is, all expenses during the life cycle of the car wash machine. Especially for machines that are significantly lower than the market price, careful examination is necessary.
