Advantages and disadvantages of traditional trash can

Each has its own advantages and disadvantages:

The advantage of the pop-up trash can is that you don't have to bend over, you just need to step on it to open the lid of the trash can and throw the garbage directly. But the disadvantage is that this kind of trash can uses the lever law in physics, and the lever and fulcrum are easy to break.

The advantage of the trash can with a rocking cover is that it is not easy to break, and the cover can be closed automatically. But the disadvantage is that throwing garbage needs to touch the lid of the trash can, which is easy to touch. At the same time, throwing garbage requires bending over.
