Using a broom is a common way for people to clean up without directly using our hands.
However, the dust or hair will sticking on the broom and still needs to be removed by our hand.
In order to solve this problem, we modeled the front part of the dustpan in a comb shape.
This design could let us easily remove the small dust or hairs to the trash can.
