3 Reasons to Choose a Robot Vacuum With a Side Brush

Without a side brush, robot vacuums leave a noticeable gap along baseboards. The main roller and suction cannot reach the edge, so dirt and dust accumulate.

High-end models using cameras or lasers still miss the last half inch. No amount of navigation technology replaces a physical brush for edge cleaning.

Side brushes are cheap and effective. They solve the problem simply, so there is no reason to skip them.
