5 Things to Know About Vacuum Roller and Side Brushes

The roller brush is the main spinning cylinder underneath that agitates dirt from carpets and hard floors so the vacuum can suck it up.

The side brush is a smaller spinning arm on the edge that sweeps debris from corners and baseboards toward the roller brush.

They work as a team: the side brush pushes mess into the path of the roller brush, which then kicks it into the suction channel.

Without the side brush, corners accumulate dust bunnies. Without the roller brush, you are just pushing air around on carpet.

You need both brushes for proper coverage — one cannot replace the other.
