Anyone else think the pre "ball" Dysons had better Bin/Cyclone designs?

So, I have a Ball Animal 3, currently the only upright Dyson still sells, was kind of quietly released a few years ago.

It has in my opinion their best ever carpet/hard floor cleaner head, but the bin/cyclone/pre motor filter is the same exact design from the DC40 all the way back from 2011.

When you pull the tall washable premotor filter out from the top of the bin, there's always dust on the inner walls and on the top of the bin cap. It doesn't seem to do a good job of actually capturing the dust as the filter sits too loose in the bin imo. My post motor filter is spotless so it must be doing SOMETHING but I feel like you never had that much dust leakage on the pre ball uprights. Every time I'm done vacuuming I take out the pre-motor filter and dust inside the walls with a Swifter duster. Just seems silly.

I don't have faith in cyclones.

If there purpose was to reduce/eliminate the need for regular filter cleaning/replacement, then they don't work well from what I've seen.

It depends...

I've only ever had TWO Dysons in my home: a DC07 Animal (sold nearly 4 years ago) and a DC17 Absolute Animal (my current heavy-duty vacuum).

First off, the DC07's upwards-mounted inner cyclones filtered exceptionally well. And the shroud holes would get clogged with some fine dust every now and then. In the first several years of ownership, the pre-motor filter remained spotless. But if you vacuum up lots of fine materials like carpet powder or flour, this stuff will bypass the cyclones and create buildup on the filter. Although we stopped using carpet powder altogether, I eventually noticed grit and some hair building up on the filter. A few years ago, I made a post here on Vacuumland about this observation: https://www.vacuumland.org/cgi-bin/TD/TD-VIEWTHREAD.cgi?41052

Now, onto my current DC17. It filters just as well as the DC07, but the Achilles' heel is that the shroud gets clogged with fine dust MUCH faster than the older vacuum. This is exacerbated by the higher volume of fine dust pickup, thanks to the incredibly aggressive brushroll. Some of the hair and fluff will even make its way to the pre-motor filter over time.

Oh, and for the record, I have NEVER overfilled either of these machines. I, as well as everyone else in my family, have always emptied the bin right when the dirt reaches the MAX mark. In fact, we dump it after every single use.
