There are three main types of trash cans: the standing, the rolling, and the fold-up. The standing trash can is the most common type. It has a large, rectangular body and a lid on top. This type is best for use in a home or office setting. The rolling trash can is perfect for use in a kitchen or garage. It has small wheels on the bottom that make it easy to move around. The fold-up trash can is great for taking on trips or storing in a small space. It folds up flat when not in use, making it easy to store or transport.
