 Hi guys!
Wondering if anyone knows the approximate RPM's of the old electrolux's metal tanks i.e. Model G to Super J, etc.
Or any of your favorite vintage brands like Eureka canned hams or Hoover Celebrities, et al.
versus:
RPM speeds of plastivacs like Dyson or Miele canisters, etc. This post was last edited 07/30/2019 at 22:23 | ||

most vintage canisters operate in range as a kirby does in attachment mode, and uprights in a similar range. the rpms ben described are accurate.
modern cleaners, and i know this from people who own vacuum shops and in the trade, are higher rpm and louder because the modern vacuum industry has convinced those screaming pieces of junk are better performers with louder higher rpm sounding motors. they operate around 25-30k rpms et al dyson, shark, miele etc. every time i run a vintage vacuum around someone whos never heard one, are ALWAYS surprised with how quiet they are. people just dont know the industry actually has them think those screamers are better machines. | ||

I have an app on my phone, much like the one in the video below, which performs a Fast Fourier Transformation on the sound coming into the mic. I have used it to successfully measure the angular velocity of my Hoover Legacy II @ ~18,000 RPM. I also confirmed that of my 1400 RPM computer fan.

Most vacuum cleaner motors on uprights in the 1920s that were not Hoovers ran between 3000 to 5000 RPM. Hoover considered those to be “small and sped up“ motors. The Hoover motor was much larger than the other machines, but turned at a slower speed. They were trying to run the brush about 2000 RPM. And they cleaned perfectly fine.
