Most robot vacuums use a side brush — a spinning arm with bristles — that flicks dirt from edges toward the main roller, and some models also do a special edge sweep maneuver along walls.Why does edge cleaning matter for my home?

Good edge cleaning means less dust collecting along baseboards and in corners, so you can go longer between manual dusting; without it, you’ll see a thin line of debris where the wall meets the floor, especially with pets or kids.
