The hack that can save pre-release version of Dyson V16

Great video showing the repair of a favorite Panasonic power nozzle from Japan. There is a little wheel on the bottom that when you set the nozzle on the floor it closes a switch that turns the motor on. When you lift the nozzle off the floor the switch turns the motor off. A steel ball is in the housing. When you invert the nozzle the ball prevents someone from pushing the wheel in and turning the motor on. This is a Japanese safety feature. I had one of these switches go but it was just dirty inside. Carpet fuzz and dirt. A quick clean up and good to go. I am pretty adept at servicing these as we use them regularly in our home.

 
At 6:24 in this video you get a clear view of what I am talking about. This is a through flow motor but it also has peripheral bypass ports. This is a 600 + watt ( Suction Work Rate rated ) vacuum that pulls ten amps on 100 volts. Panasonic calls it their "3D Inducer Motor" You can also see how the vanes on the fan protrude all the way into the bulging suction inlet of the fan housing. The original Panasonic motors used in the Elite upright and canister were like this.

I just found this video and sure wish I knew about it when I took my first one of those vacuums apart for service. You can see there is some technique involved and I had to suss my first one out on my own. This example has been apart before. The original foam on the outside of the motor housing and inside the body over the exhaust openings has been replaced by what looks like HEPA bag material. I do something similar when I refresh these because the open cell foam is terrible. You can see from the carbon dust the machine is well used yet look how clean the bag chamber is. Panasonic sells an outstanding synthetic bag for their Japanese model vacuums which I always buy for ours. I have a half dozen like this, different model variations but the same basic layout. Vacuum hose and power nozzle combined weighs 2.6 kg, or just under 6 pounds but the power at the nozzle is more than a Kirby has. Stunning little vacuums. After trying one of these my wife won't touch either Miele or anything else for that matter.

@cheesewonton you mean the subject of this thread?

What I can't get over is that the motor in my Kenmore 600 Series resoundingly spanks my Panasonic built Elite with its 3D Inducer Motor. Suzhou Cleva is not using Panasonic motors. They have their own supplier ( they make their own motors for their Vacmaster line but not sure about the Kennys ) and where the Elite used to be at the top of the hill for suction and airflow this new 600 I have just blows the Elite away. 72 cfm at the hose end is huge ( consider my Patriot barely musters 30 cfm ). The Elite is making around 47-ish cfm at the hose end, same as my Japanese Panasonics. The 600 isn't perfect but it's darn good and certainly the best value canister vacuum on the market.
 
@Vacuum Facts, the full review can still wait for later, but would you reveal us the mod that even this thread is asking for, as part of your myth-busting anthology leading to the review itself? This way, users would be aware of what's really wrong with V16, and that should hopefully combat any misinformation that you expect most major reviewers will definitely fall for.

Like, isn't this the point of this very thread?

@Vacuum Facts, I did all this to help you debunk misinformations. Why haven't anybody properly talking about the V16 Piston other than us? Why? It doesn't just sting at this point, it's a torture! No offense, though...

@cheesewonton. CFM isn't enough. We needs suction lift.

I understand that. The Kenmore has a female hose end with an irregular shape. I can't get a reliable suction reading on it. I'm working on that.

It's just you asking, and like 10 times now. I don't think many others are really interested. Maybe take your requests to DMs?

At some point it all boils down to preference. Some people like and prefer dysons, I prefer a Kirby cause I know that they just fill bags and bags with dirt. Amazing performance in my use case. I have a lot of pet hair, larger debris and fine dust though. I find that even a Dyson stick vac struggles on all this kind of stuff. A Kirby is not perfect though it is better than most for me.

And yet in my home with our pet hair a low hour Avalir 2 we bought new struggles to clean two of our area rugs that a Sebo, Patriot, Metrovac, VAPamore ( CRAPamore ) or Kenmore canister and their respective power nozzles have absolutely no problem cleaning well. No the rugs do not have rubber backing. They can breathe, but the weave is both short and extremely dense. One click high and the brush barely skims the surface cleaning nothing. Click the height down one more click and the brush bogs and squeals the belt. Useless. I have the same problem on these rugs with Wessel-Werk and Miele power nozzles btw.

Interesting. There is different types of dog hair. What type of dog do you have? Mine are cocker and sprocker spaniels with medium short and fluffy coats. Your dog hair may be very different.

Border Collie mix and Husky Malamute. The latter leaves a smear of hair where he laid on a rug and shoots artists paintbrush sized chunks of hair when he's blowing his coat. Just walks by and ka-chung, out pops a big clump of hair. Also our sweet brown mackerel Tabby boy sheds almost as much as the Husky. And it's really fine hair. Our other cat hardly sheds, or at least it is not noticeable.

I have watched hi lecture, a lot didn't make that much sense to me.

That's because you didn't really understand the science behind vacuum cleaners, as @Vacuum Facts told us.

I tried to figure out the fix because VF told me to, so I had to constantly correct the Google Gemini 2.5 Pro. The specifics (and thus the possible fix) is in the Piston thread.

I understand that you need airflow, suction and agitation combined. I understand that my floors are cleaned well every time I use it.

Out of the three, the airflow needs special care. Airflow speed should be prioritized over airflow volume - too much airflow volume is an indication of either leakage or lack of resistance (or a combination thereof).

I've got news for you... While much of what VF says in his lecture is true, there is also plentiful misnomers and mis-applications of the theories and concepts, as I have vainly attempted to demonstrate in a plethora of posts.

In short there he does a good but by no means perfect explanation of the science, but they are far from perfect. His (and every other reviewer/so-called experts) reviews etc should all be taken with a good measure of salt.

You've explained and demonstrated absolutely nothing and shown no significant understanding or knowledge of what's true. People can make up their own minds from what's available now.

Sorry @herbicide, that's yet another reason to ignore you. You should've watched the lecture over and over again.
