What is the working principle of an industrial vacuum cleaner?

Industrial vacuum cleaners are designed and manufactured to address cleaning challenges in the industrial production sector using the principle of vacuum. The vacuum principle involves using vacuum to achieve the movement of objects. Currently, we mainly encounter two types of products that utilize the vacuum principle: (1) Vacuum cleaners (including industrial, commercial, and household categories): these use vacuum to move waste and dirt to a designated collection point, such as a trash bin. (2) Logistics or material handling: for example, a feeder uses vacuum to elevate or lower raw materials to a specified position.
