3 Reasons the Roomba s9+ Cleans Cornels Better

D-shaped design reaches corners Most robot vacuums are round and leave a crescent gap in corners. The s9+ is flat on the front, so its brush contacts both walls at once.

Superior suction power The s9+ has stronger suction than other Roomba models, pulling debris from edges more effectively.

Systematic straight-line pathing It cleans in rows instead of bouncing randomly. This ensures edges are covered methodically, not by chance.
