How can I find out the suction airwatts on each brand of vacuum cleaner??

Dyson is the only vacuum cleaner I have found which lists the airwatts.

Have you tried checking the manual? Most of the times, these important labels are properly identified in your vacuum cleaner manual.

If it isn't there, you can call the manufacturer and ask any of their customer representatives. It will definitely speed up the process of searching for your vacuum cleaner's suction air watts.

Take note, though, that 100 air watts is already enough for you to consider a vacuum cleaner truly effective. But this is only for an upright.

If you have a cylinder vacuum cleaner, it should generate more than 250 air watts. Vacuum cleaners that are considered to be the best in the market are those with air watts ranging from 350 to 450.
