Main Equivalency! Which one would you take?

I agree with blackheart here. If you know enough to add context your different experiences and opinions will make it biased. Those who don't know that much about vacuums will be unbiased but inaccurate, thus thereis non-biased opinion.

Dyson is the one who has duped the public into thinking he invented the cyclonic bagless vacuum when in fact such vacuums have existed and have been in production continuously since 1926 courtesy of John Newcombe and Leslie Green. Their design would be renamed Rexair in 1929 and exists in production to this day. But James Dyson was apparently either ignorant of this fact when he claimed to have invented something that already existed, or he was patently dishonest. Either way there is was decades late to the party and has no claim other than selling a lot of brittle fragile plastic junk at inflated prices while flim-flamming the public into thinking he invented something he didn't. Not to put too fine a point on it but he is a con man. This hero worship he seems to engender is beyond me to understand. Even if he did invent the bagless cyclonic vacuum what he sells is low quality junk.

@centralsweeper63 @blackheart that would be straight-up misinformations.

Dyson himself invented the cyclonic vacuum cleaner, inspired by the industrial cyclones for sawmill and factories, @cheesewonton, not the "mere" bagless vacuum cleaner which you are describing. Dyson used proper cones with actually massive centrifugal force to filter out microscopic stuffs. Bagless vacuum cleaner doesn't have to necessarily be cyclonic, although almost all of them now are. Also, no comment on durability, though Dyson the company did had to test their vacuums so they could last up to 10 years for the corded and up to battery's lifespan for the cordless.

John Newcombe, the man who invented those industrial cyclones way back around 1920, the very same cyclones that James Dyson claims as the inspiration for his vacuums, teamed up with Leslie Green to design the first cyclonic bagless vacuum based on his industrial cyclone design and began selling this in 1926. A version of that original cyclonic bagless design became the Rexair vacuum which is still made today. The man who invented the industrial cyclone also invented the very first vacuum to use a cyclone to separate dust from the airflow. And all this happened before James Dyson was even born.

Does the Rexair really be able to spin the microscopic stuffs down inside the machine? Or does it circle around? It may be the first bagless, but is it really the first true cyclonic?
