Suction pressure, which is measures in kilopascals, is another great way to discern a vacuums power, although fewer manufacturers disclose this number. But if they do — look for a range of between 5 to 20 kilopascals.
What does kPa stand for vacuum?
Its typically measured in kPa (kilopascal). Without going into details, Pascal is the measurement of pressure and the kPa unit of a vacuum cleaner is the difference between the normal atmospheric pressure and the pressure inside the vacuum cleaner hose. More the difference, higher the suction pressure.
