Suction power in pascals (Pa) tells you how strong a robot vacuum really is

Suction power is measured in pascals (Pa), and higher numbers mean stronger pickup — entry-level robots sit around 2,000-2,500 Pa, while premium models push 5,000-6,000 Pa. The catch is that raw suction matters most on carpets; on hard floors, even 2,000 Pa is plenty since debris doesn’t get trapped in fibers.
