Regarding Dyson, is there actually an advantage in the three stage one instead of the older two stage cyclone thingy?

The problem with a lot of bagless vacuums in the past was that Dyson held the patent on staging two cyclones for better filtration (in my opinion, it's a loving obvious thing based on its physics, but anyway), that led to other manufacturers resulting to a single cyclone for filtering coarse dirt and resorting to filters for fine dirt, kinda defeating the point. Dyson's patent ran out a while ago, two stage cyclonic vacuums should be available from everybody now. Dyson's new thing is three stages and this is patented. The final stage on these has way smaller cyclones than the two staged Dysons and should be able to filter way smaller dust particles. Whether there's an advantage or not depends if you skipped paying for a version with HEPA filter (which again would need cleaning).

The filter isn't the problem, but the vortex tubes that'll coat themselves with fine dust. Take the vortex unit and start tapping the bottom of it against a hard surface, ideally outside for obvious reasons, and see how much poo poo will drop out of it.

Sometimes I use my shop vac in the garage to vacuum out those holes. I maybe have to do this once every 6 months or so with how heavily we use our vacuum.
