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.
Suction on Wiki Shopping
How many of the 164 robot vacuums on Wiki Shopping fall in each suction group, on October 23, 2026.
| Stated suction | Robot vacuums |
|---|---|
| Under 5,000 Pa | 2 |
| 5,000 to 14,999 Pa | 14 |
| 15,000 to 29,999 Pa | 37 |
| 30,000 Pa and up | 27 |
| Not stated in the listing | 84 |
To see the higher figures in one place, use robot vacuums with strong stated suction. The 15,000 to 29,999 Pa page covers every vacuum type in that range, not only robots.
Other specs to compare
- Mopping. Robot vacuum and mop combos add a mop pad or water tank.
- Pets. Vacuums for pet hair are those whose listings name pet hair.
- Other types. If a robot is not the right fit, compare stick vacuums, upright vacuums and handheld vacuums.
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.
