[0002] In the field of building decoration, wall polishing is a crucial basic work, and its quality is directly related to the final decoration effect of the wall. The traditional building wall polishing tool has exposed many problems to be solved in the long-term use process. These problems not only affect the construction efficiency and quality, but also cause adverse effects on the health of construction personnel and the working environment.

[0003] In terms of dust treatment, the traditional polishing tool generates a large amount of dust during operation. These dusts fly freely and quickly fill the entire construction space. The main components of the dust include wall debris, particles and possibly harmful substances such as formaldehyde, benzene, etc.
