Who really invented the cyclonic vacuum cleaner?

Spinning air give you centrifugal force of some amount. Centrifugal force is what a cyclone is.

I don’t really consider the Rexair to be cyclonic really, it doesn’t spin the air around to separate dirt from it, although the original design did rely on centrifugal force, it wasn’t generated by a cyclone. Filter Queens, in my eyes, are cyclonic, but a very basic form that only flings the large dirt to the outside of the bucket. I’m pretty sure various industrial vacuums (dust collection systems in factories and woodworking shops kind of thing) as well as central vacuum units were the first to use cyclonic action as we know it today.

The original patents called it a cyclone. I posted them on another thread with our friend V-F a couple of months ago. The inventor called it a cyclone then some dude on the internet comes along 100 years later and claims otherwise. Hmmm. Compact / Tristar were claiming their configuration creates a cyclonic action inside the bag chamber long before His Unholy Excremence Lord Diesoon was peddling vacuums, though the axis of rotation with the Compact / Tristar design is horizontal and perpendicular to the longitudinal axis of the vacuum. Air goes in the top and does a big loop before entering the motor leaving the dust piled up against the front face of the bag. There is more than one way to create a cyclone in a vacuum. Expand your mind.

@Vacuum Facts was right. Dyson pioneered the real cyclones in vacuum cleaners.

Well um, keep in mind, he improved it from working poorly to working just meh.

I am remembering my first year university physics professor telling us centrifugal force is a pseudo force. Doesn't exist. What does exist is centripedal force. An object in motion wants to stay in motion, that means in a straight line. Newton's Second Law. To get it to change direction there needs to be a force. To get something to go around in a circle you need centripedal force that is accelerating the object or objects towards the center of rotation. The force vector is towards the axis of rotation.The dirt drops out because it is heavier and the centripedal force of the air cannot overcome the inertial of the dirt, which wants to continue in a straight line.
