The strength of a vacuum cleaner's suction power is typically measured in pascals (Pa) or air watts (AW). Pascals measure the pressure difference created by the vacuum, while air watts take into account both suction power and airflow.
some of the most powerful residential vacuum cleaners on the market had suction power ranging from approximately 20,000 to 100,000 pascals (Pa) or about 200 to 1000 air watts (AW). However, these numbers might have changed with newer models and advancements in vacuum cleaner technology.
It's worth noting that the suction power is just one aspect of a vacuum cleaner's cleaning performance. Factors such as brushroll design, filtration system, and overall engineering also play crucial roles in determining how effectively a vacuum cleaner can pick up dirt and debris from different surfaces.
When choosing a vacuum cleaner, consider the specific cleaning needs of your home and the types of surfaces you'll be cleaning. A vacuum with moderate to high suction power, combined with other essential features, can provide excellent cleaning performance.
