Sweeping is not just pushing dirt forward. It is a controlled process of capturing, holding, and directing particles. When bristles are not designed for the surface, they create airflow that lifts dust instead of trapping it.
For instance, on polished tile floors, thick and stiff bristles generate excess resistance. This causes micro-particles to scatter sideways rather than move into a collection line. Over time, this leads to visible dust settling back within minutes.
On the other hand, softer and denser fibers create a slight drag that helps in binding fine dust, ensuring it moves consistently in one direction.
