Short summary
We studied how street sweeping vehicles remove dust and debris by combining rotating brushes with suction. Using computer simulations, we showed how brush angle, speed, and suction strength work together to influence cleaning results. Our findings reveal that the right balance of these factors creates a strong airflow zone that captures particles efficiently. This research helps improve sweeper design, leading to cleaner streets, lower energy use, and healthier urban environments.
