Background technique

After decades of development in my country's sweeper industry, products have developed from a single pure sweeping type to a variety of current types, and product performance and product quality have rapidly improved. With the development and progress of society, we are no longer satisfied with vacuum cleaners in a simple sense, and will put forward more requirements from the aspects of multi-function, environmental protection, economy, etc. The market is calling for cleaning vehicles that can meet various needs.

With the improvement of people's requirements for the living environment, the cleaning methods and concepts of regionalization and gridization, as well as the degree of real purification of fine and coarse particles in the atmosphere such as PM2.5 and PM10, have also become the focus of attention. In the context of the gradual disappearance of China's cheap labor advantage and the sharp rise in labor costs, factors such as "labor shortages" and "high costs" in the industry are intertwined and superimposed, increasing the operating costs of labor management companies. In the process of continuous evolution, large-scale vehicles gradually withdraw from the historical stage. R&D personnel are constantly pursuing miniaturized, multi-functional, and convenient vehicles that can truly purify the air, remove dust and reduce haze.
