Something old
Here's a private labeled compact C-8, it did better than I thought it would. I also learned that the exhaust grills are restrictive. despite the "filter" material being extremely open placing the grill on it does reduce airflow. Hm I can't find my waterlift at the body. It seemed to be about 76" With the exhaust cap removed body airflow went from 103.77 to 115.07

Wow
What a difference with that exhaust cap removed!

I have a c8 I painted green. I put new motor in it. I did airflow with my anamometer two days ago. I did only cfm I got 113.
That's a cool version. It has the clear sparling handle grip. It also looks like exhaust cap is original with IEC on it.
Is the motor the same from c8 to the silver compact then it went to higher powered two speed In red or black version. I remember asking about the motor. I realized the one speed is 5.7 amp motor and the newer is 6 plus inches.
Did hoses come like yours pictured?. I bought c9 had a newer hose and c8 hose is straight suction no cord but I put new hose on it. If you add the power cord what gauge of wire is used?
Thanks

Yup
I'm quite shocked at that exhaust cap's resistance the material is really loosely woven so you wouldn't think it would matter that much.
The exhaust cap is blank if it did have the logo it fell off at some point.
No, the DXL is definitely stronger with about 130 body cfm and 90" of suction it has a good amount more power than this C8. I'm not exactly sure what motor is in this despite me tearing it completely apart cleaning the fans out and such. I do know it's a lamb motor and it Found a series of numbers on it 11 127 something the last number seems to be a 3 or 8 but I can't really tell it was worn off.
As for the hoses I don't know I thought it was a generic at first but looking at it's hose grip I think this may indeed be genuine just before the release of their internal wire electric hose? As for retrofitting it You just need to buy a pigtail. Link to one 8 ft cable below. This one may be a little long but it'll work you just need to affix it to the outside of the hose

Cool still have ur C8 .
Thats how i run my Compact c9 whit bag and cap works good for my use.

I replaced the motor and it was same motor for pre 1993 one speeds. I just checked those numbers are original motor to the model.
I think motor was the same but dxl motor is bigger and has 1.5-2 amps more power than motor I have.
Is proteam and dxl motor the same. I would guess the smaller protea. Is same as compact and proteam is different as 150 cfm is not in any motor that fits a compact. I think 2 speed may fit in c9 but I could just buy a dxl for a little more . The motors are model specific and just altering would be a water.
Thanks for info on hose.

Sebo K1 & Electro Helios U318 (1979)
Here is two canister vacuums.
Age difference 40 years.
Results were very surprising.
Woven hose results for the Electro Helios: airflow 90 cfm suction 83".
Plastic hose results for the Electro Helios: airflow 99 cfm suction not measured.
Hose results for the Sebo K1: airflow 93 cfm suction 87".
Note that Sebo exhaust filter removed it got 100 cfm. In the Electro Helios it had no effect to the results (thin fabric filter).
Both used fleece/hepa bags.

A new challenger approaches!
I just ordered this today, so it should be here either this or next week. This may have the most airflow of any vacuum measured to date. That is just speculation though.

Yeah...
Initial testing with the NSS has been....lower than anticipated I think i was getting about 118 hose cfm off a 1.5" diamater hose. It will be undergoing modification to get a disposable bag in it though. The original "leather" filltube was all torn up.
Anyways I just finished cleaning this up today. It's not bad, but not great. The nozzle also has quite a bit of dead space. I had one of these a a number of years ago under the sanitaire name, but it was bagged instead of bagless.

Hmm
I knew it was a pig. You forget the vacuum bag is the size of a freaking garbage can. It may only run 120 cfm but how many vacuums can inhale a garbage can and still be pumping 120 cfm. It's a pig because it eats everything including the big bad wolf. It doesn't inhale the fastest but it inhales everything.

How many?
Well...I'd assume most backpacks could. They don't have the same capacity as the M1 though. I was just disappointed because I had such high expectations for it. With the Giant 8" diameter fan I figured they could really move some air. Perhaps once I have my bag conversion in place I'll re-test it, having a smooth airpath instead of the raggedy cloth filltube may improve it.

I think the same thing for the Pig bags-get rid of the cloth fill tube and go to one like that Kirby has.The Pigs cloth fill tube can trap debris in between the cloth tube and the metal tube just inside it.And the cloth fill tube can get damaged by debris going thru it from that HUGE fan.One of my bags fill tube was shredded after cleaning up a basement reno job.The Pig gulped the stuff down better than any Shop Vac type vacuum.Fan was undamaged--it ate conduit box slugs(bent them over)A 6" piece of 14Ga Romex cable-many nails and cable staples-wood bits,sawdust,plaster dust.Had to replace the outer bag.My friend paid for the replacement.It was fun listening to the pig dinging and thooping that stuff into the bag!That Pig is still going strong to this day!!!!Contrast that to many shop type vacuums where the motor was killed by plaster dust and moisture.

This is as far as I go with this machine. I can't see myself investing anymore money into it with measurements like this. It's a neat machine though and much easier to clean than Rainbow. Machine measurements would have been a pain and likely inaccurate it has a square inlet and when the hose isn't plugged into the machine it runs on low speed for air cleaning.

Another Shark
The L denotes the hard floor setting and the H for carpet, Low and High. I didn't measure the opening for CFM density as these leak a good amount of flow through the front so I wasn't sure if the front roller should be included as part of the nozzle opening. There is a suction relief valve in this so the suction listed isn't it's full power.

More Lindhaus!
A friend of mine purchased this to clean hallways and vacant apartments. I measured it with both the straight suction kit and the Electric kit. This is a backpack vacuum, but it can be converted to a canister with a wheel kit.

Yet another backpack
As far as I can tell the difference between the SC530 and the Sc535 is an added hepa filter.
I've gotta say 105 hose cfm is pretty poor the Proteam FS6 manages nearly 150 CFM with the same 1.5" hose. The difference is quite noticeable when you're cleaning with them the nozzles have more sticking power when you're using the proteam.

A hoover
This is one of the newest additions to my collection. I think this may be the best featured commercial vacuum for the price. Long life belt with a hall sensor, two speeds, easy to use onboard tools, a pigtail for easy cord changes, height adjustment, decent bare floor cleaning, both charcoal and hepa filtration are all included. I'm unsure of it's reliability over time but when your other mid 200 commercial options are very basic machines like carpet pro this is a great option.
For those unfamiliar with them they remind me more of a windtunnel upright but with some additional features.

Finally!
The NSS M-1 This is a 12 amp version.
The original leather-like filltube was replaced due to the last one being torn to hell. This change most likely does effect it's flow. Due to the odd design I'd say the Kirby filltube most likely improves it.
Strangely there's a sticker on the side saying it has 117 CFM at a 1.5 orifice which matches up with the hose CFM.
As we can see the machine airflow is ridiculous! It was actually able to hold the vane in place.
Regarding the hose airflow I checked the hose for obstruction before testing and have tested it briefly before getting somewhere around 115.
