If it's just floating dust, then natural rain can clean it. However, although the artificial turf field generally prohibits throwing and throwing debris, it is inevitable that various garbage will be generated in actual use. Therefore, the maintenance of the football field must include regular cleaning. Lightweight garbage such as shredded paper scraps, nutshells, etc. can be handled with a suitable vacuum cleaner. In addition, you can use a brush to remove excess garbage, and be careful not to affect the filling particles.
