Comparing Shop Vacuums With Air Watts

When comparing shop vacuums, one important metric to consider is air watts.


Air watts measure a vacuum cleaners suction power and provide a reliable indicator of its performance for comparing shop vacuums.  In many cases, suppliers of shop vacuums do not provide enough enough information about the vacuum to help the consumer make a comparison  However, don’t despair as you can use the Air Watts Calculator at Cat 6 Tools to calculate this useful Air Watt rating .  All you need is the Airflow in CFM and the Suction in Inches of Water.  Enter these into the calculator and you can then calculate the Air Watts.  The calculator will also help you determine other useful numbers.

Here are some key steps to effectively compare shop vacuums using air watts:

  1. Understand air watts: Air watts is a unit of measurement that combines both airflow and suction power. It represents the actual cleaning performance of a vacuum cleaner, considering both the volume of air moved and the strength of suction.
  2. Identify the air watt rating: Look for the air watt rating specified by the manufacturer for each shop vacuum you are comparing. This information is usually provided in the product specifications or on the packaging.
  3. Consider the intended use: Determine your specific cleaning needs and the type of debris you will be dealing with. If you require a shop vacuum for heavy-duty tasks, such as cleaning workshops or construction sites, opt for a higher air watt rating to ensure sufficient suction power.
  4. Compare the air watt ratings: Evaluate the air watt ratings of the shop vacuums you are interested in. Higher air watt ratings generally indicate greater suction power and better cleaning performance.
  5. Look for additional features: While air watts provide a valuable measurement, it is essential to consider other factors too. Assess the capacity, filtration system, hose length, accessories, and overall build quality of each shop vacuum to ensure it aligns with your requirements.
  6. Read reviews and seek recommendations: Consult customer reviews and seek recommendations from trusted sources to gain insights into the actual performance and durability of the shop vacuums you are considering.
  7. Budget considerations: Compare the air watt ratings in relation to the price of the shop vacuums. Evaluate the overall value for money and choose a vacuum that offers a balance between performance and cost.

By following these steps, you can effectively compare shop vacuums using air watts as a reliable indicator of suction power and make an informed decision based on your specific cleaning needs.
