In an innovative way, the discomfort of the traditional suction and blowing machine in the user experience has been changed. Through the concept of balance car, the weight that originally needed to be loaded on the user is transferred to the balance car, freeing the user's body. At the same time, the balance car gives users faster and more convenient maneuverability, which not only greatly improves the use experience, but also makes a breakthrough in efficiency. The two different working states greatly improve work efficiency and enhance user experience. Modular dust box design and crushing function make dust collection more professional and efficient.
