Poor filtration on Shark vacuums

I do not believe that in normal use, the Dyson Cinetic will leak dust into the motor. Mine has been used at my home for two months now, as the only vacuum, and there is absolutely no dust leaking into the motor. The first time I saw the video where the kid claimed to have found all that dust, I realized the machine had been tampered with. It states on the cleaner not to use it on drywall dust, and clearly this kid did just that (or talc maybe).
Sebo_fan, yes, I have learned about misleading claims on the free Vine vacuums I've used.
I have already seen that video. Plus, I'm subscribed to Kode1996. Those filters are non-washable lifetime post-motor filters. Due to the Cinetic science being so efficient, there is no pre-filter. I haven't used a Cinetic upright yet, so I can't comment on whether or not dust leaks into the motor.
I have no idea where Kode lives! Perhaps he lives in a rural area? IDK.
But I'm not the only one who's ranting about poor Shark filtration! Kode made a video showing the bad filtration of his Rotator Powered Lift-Away vacuum.

Aren't the newer "Lift Away" Sharks single stage cyclonics? That's probably the biggest contributator to "poor filtration." I have a single stage woodworking cyclone but it incorporates a few design features to ensure higher seperation than the relatively simplistic single cyclone designs on some bagless vacuums. The multistage cyclonics seem to be the design to go with if you need the bulk of the seperation done down to the fines and then the remainder of the fines get captured by the prefilters.
Even if the Cinetic's rubber cyclone design captures most of the fines, I would of moved the HEPA filter infront of the motor like Sebo has the prefilter infront, just to ensure the motor never deals with any bypass in any condition like overloading the filter.
Speaking of drywall dust: I found that Henry HEPAFlo bags (Crudely fitted to a ShopVac since they have a bypass motor) seem to do a great job, ditto with the synthetic Sebo Ultra Bags. No dust on the filters from my experience. It also seems that the ShopVac drywall bags are just microlined paper bags, similiar to my Sebo HEPA Box Ultra Bags.

Something I've always wondered about washing filters
You know how when you use a humidifier with hard water, how some humidifiers have filters that trap the minerals so that you don't end up with white dust everywhere. Well, since we're talking about washing filters, when you wash the filter, if you have hard water, won't some of the minerals from the water get in the filter you just washed clogging it somewhat?

That would make sense the residue would contribute over time.

Hard water washing with filters.
Generally once the filters are dry, hard water minerals etc usually shake off.

Yes
All of the newer Shark Lift-Away vacuums are single-cyclonic. One exception to this was the original Shark Navigator. It used 21-cyclone technology. However, I did some research, and it turns out that the cyclones would clog easily and most people wouldn't clean them. Euro-Pro made the switch to single cyclonic on the Shark Navigator Lift-Away, released in 2010. I guess single-cyclonic is more reliable! It's not that big of a deal to wash the filters every 3 months.
I have never had a problem with hard water minerals ruining filters. Depending on the vacuum, I will use dish soap to wash filters. I make sure to rinse the filters really well, or else they will get sticky and clog more easily.

Original Shark Navigator had rather strange multi cyclonic system. Normally those small cyclones separate the fine dust to the inner part of the main bin.
Navigator had closed cyclones which collected the fine dust in them. They didn't lead to anything. Instead you had to empty the cyclones. I think it wasn't very good idea.
Not only you had to empty the bin, but also cyclones needed to be emptied. Too complicated for the normal consumer.

I remember the Shark Infinity had 21 cyclones too. Where they set up like the Navigator that led to nowhere?
That cyclonic system...
...Really is rather weird! They say that you have to manually empty the cyclonic chamber every 3 to 6 months.
I've never used an Infinity (not the car brand) vacuum, but I've seen pictures online of them. I did a quick search, and it turns out that they used 24-cyclone technology, 3 more than the Shark.
Here is a video review of the UK model of the Shark Navigator from Roger (ibaisaic). He discusses the cyclonic system starting at 2:30.

Anybody?
Isn't anybody interested in this video?

Nope. I never wish to own one.
A friend of mine has one. I'm happy for him, lolol
I saw a Shark box on trash night at my cousin's house. I have other people who bought them. Some were happy. Others................

I am Nick, I just saw this! I love Roger's videos. How did I not know that Roger did a video on the shark? Earlier today I used my Dirt Devil Scorpion on blower mode to clean the cyclones on my Dyson DC65, Dyson DC34 and Hoover Air Steerable. I wish they could come apart like this.
This is what I do on my free time, take my vacuums apart and clean them out. My friends think I am so weird
