n0oxy,
It's nice, but too new to be Whirlpool or Ryobi. Definitely by Panasonic.

Quiet vac, loud powerhead
Kenmore whisper tone sounds very nice and soft.
My problem with the quiet canisters is that the powerhead is louder than the canister itself.
For example Lux D790 Royal. It's quiet and soft sounding, but when I use it on the low pile carpet powerhead makes that loud roar sound. At least it's pretty quiet on the shag rug.

Mike,
That is so true. My Eureka, (Electrolux) Oxygen power head is very loud compared to the cylinder itself.
Now my older Eureka roto-matic vibragroomer is a very quiet power nozzle, with an older metal fully encased sewing machine type motor in it.
When connected to my central vac, I can actually talk on the phone while vacuuming.

loud Kenmore power nozzle
Here's a video that demonstrates what you are talking about. You can hardly hear the canister motor, but the power nozzle is loud and clear.
Also interesting to see the work he's done to restore the vacuum to like new condition.

My mom has a Whispertone canister like the one above. The motor is a bit smaller than the older ones but still has a pleasant sound. I agree the PN adds quite a bit of noise-those ones were kind of buzzy.
My Progressive canister has an even smaller motor and a much higher pitch sound, especially with the HEPA filter. It's pretty quiet on low.
My Electrolux Grand Marquis is the opposite, the machine sounds like a fighter jet roaring but you can barely hear the PN over it.
New uprights with the small motors almost all sound like screamers to me. But even Elites and Bravos 20 years ago were too loud for me.

cogged belts;
are generally noisier than smooth belts.
I don't find the Kenmore P/N that loud.

Sven,
I never knew that. Still learn every day.

another nice sounding motor
Here is a video of the Electrolux 2100.
I'm not sure if this was a one or two stage motor, but it actually sounds a bit better than the current Aerus classic model, I'll include a video of that for comparison.
The newer aerus classic actually has a higher pitch, not as bad as some of the other screamers, but I think the motors in the older models actually sound better.

The motor in the Electrolux 2100 is a 2 stage thru-flow (flow thru) motor.
I have a bare one sitting on the bench hooked up. (I should do a video)
This diagram from from Ametek shows how it works.

That article from the Lindsay Manufacturing site was interesting. Most canister vacuums use the flow through motors, and even some central vacuums do now as well. One of my central vacuum units, the vacumaid garage vac pro uses a two stage flow through motor, it's higher pitched, but it is quite powerful. I'm pretty sure the motor in the current Aerus classic model is only one stage, and you can tell that it spins faster. A lot of the electrolux models, such as the marquis, diplomat, ambassador, and 2100 sound very similar, I'm wondering if all of these models actually use the same motor.

another good sounding vacuum
I'm not sure when these were out, but the motor sounds good with these, not that annoying high pitch scream, it's a canister called the hoover celebrity.

N0oxy,
yep, that Hoover QS 2 speed sure is nice. I like the 2 speed power nozzle as well. No one else offered that to my knowledge.

interesting article about vacuum motors
This article talks about good vacuum design in general, but it mentions the trend of moving to one stage motors that spin much faster and thus will where out quicker.

Dyson DC07
The Dyson DC07 might have had two different types of motors; it certainly had modified fine-particle cyclones.
The first generation of DC07 had vortex finders on the small cyclones, which had aerofoils similar in design to aircraft propellers. These machines had that ear-splitting whistle.
The later versions had a simpler vortex finder more like the DC14 & DC15. The noise was more of a dull roar. The length and/or diameter of the cyclones might have been altered too.
