Pascal figures describe a suction claim under specified conditions, not a complete floor-cleaning score. Brush design, sealing, airflow, navigation and debris type all affect the result.

A practical checklist

  1. Compare pickup evidence collected under similar conditions where it exists.
  2. Check brush maintenance and access to the intake.
  3. Treat figures from different brands or dual-turbine systems cautiously.

What this looks like at home

Eufy X8 Pro's two turbine ratings should not simply be added and ranked against a single published figure from another robot.

Follow the debris path

Check What matters
Floor opening Look for lodged debris or a displaced brush cover.
Bin and seals Check closure and seating after emptying.
Filter Follow its own cleaning and drying instructions.

A mistake to avoid

Do not promise that a higher Pa number guarantees better carpet cleaning.
