When it comes to measuring the performance of vacuum cleaners, air watts are a metric that is gaining
popularity. Air watts are a measurement of suction power, which is a critical factor in determining the
effectiveness of a vacuum cleaner. In this white paper, we will explain what air watts are and why they
are important in measuring vacuum cleaners.
What are Air Watts?
Air watts are a metric that measures the amount of suction power a vacuum cleaner can generate. It
takes into account both the strength of the motor and the efficiency of the airflow system. Air watts are
calculated by multiplying the airflow (in cubic feet per minute, or CFM) by the suction (in inches of water
lift, or “H2O”). This calculation provides a more accurate measurement of suction power than
horsepower, which is a measurement of power output rather than suction power.
Why are Air Watts Important?
Air watts are important because they provide a more accurate measurement of suction power than
other metrics such as horsepower. A vacuum cleaner with a higher air watts rating will generally have
better suction power, which means it can pick up more dirt, dust, and debris from floors and surfaces.
This is especially important for households with pets or allergy sufferers, where effective suction power
is critical for removing pet hair and allergens from carpets and upholstery.
Air watts also take into account the efficiency of the airflow system, which is important for maintaining
suction power over time. A vacuum cleaner with a well-designed airflow system will maintain its suction
power even as the dustbin fills up, while a vacuum cleaner with a less efficient system may experience a
drop in suction power as the dustbin fills.
Finally, air watts provide a more standardized and reliable metric for comparing different vacuum
cleaners. Unlike horsepower, which can be measured in different ways and may not accurately reflect
suction power, air watts provide a consistent and reliable measurement of suction power that can be
used to compare different models.
Conclusion
Air watts are an important metric in measuring the performance of vacuum cleaners. They provide a
more accurate measurement of suction power than other metrics such as horsepower and take into
account both the strength of the motor and the efficiency of the airflow system. Air watts are important
for households with pets or allergy sufferers, where effective suction power is critical for removing pet
hair and allergens from carpets and upholstery. By understanding what air watts are and how they are
calculated, consumers can make informed purchasing decisions and choose a vacuum cleaner that
meets their needs and expectations.
