Robot Vacuum Suction (Pa), Explained

Robot vacuum suction is a maker's pressure figure in pascals; about half of the robot vacuums we list state one, most often 15,000 to 29,999 Pa.

The short answer

Robot vacuum listings often give suction as a number followed by "Pa". Pa stands for pascal, the metric unit of pressure; NIST, the US measurement agency, defines one pascal as one newton per square meter. A higher figure means the maker claims a stronger pull of air.

Of the 164 robot vacuums listed on Wiki Shopping on October 23, 2026, 80 state a suction figure. The largest group is 15,000 to 29,999 Pa (37 robots), followed by 30,000 Pa and up (27 robots).

What the number does and does not tell you

The Pa figure comes from the maker. Wiki Shopping cannot check how each maker measured it, so the same number from two brands may not mean the same thing in your home. Wiki Shopping shows the figure as the listing states it; we do not test vacuums.

How well a robot cleans also depends on things the suction number leaves out, such as its brushes, its dustbin, how it maps rooms and how it handles rugs and edges. Treat suction as one spec among several, not as a ranking.

How we count

Each robot vacuum on Wiki Shopping has its suction read from the store listing and placed in one of four groups. A robot whose listing gives no suction is counted as "Not stated". The counts change as listings are added or removed.
