Even More airflow tests (part 3)

Do you have a bag that has the original cloth fill tube to compare to the "Kirby" fill tube bag?This is a good idea to repair bag fill tubes that are worn.When I helped remodel my friends home years ago the cloth fill tube was torn up from nails,cable staples,romex strippings and even a piece of unstripped romex .Found these in the bag-at the time did not use a paper bag-just the cloth one.Had to go to Winchester,Va to get a replacement cloth bag and a pack of paper bags.My friend payed for them.Use a paper bag in the new cloth bag to clean out his fireplaces-worked well!!!Put the paper bag in the metal trash can in case of live ashes.Those can withstand trips thru a vacuum!!The NSS cloth fill tubes can't with stand hard stuff ingested by the fan.The new Grey bags have a different cloth fill tube.Would like to see NSS use rigid fill tubes-like the Kirbys.So-when a cloth fill tube goes in one of my NSS bags will try a Kirby fill tube.And you can use the bag alone without the paper bag if desired-good for heavy bulk pickup.The NSS did better than the mans Craftsman shop vacuum in picking up stuff.Also bought a power nozzle for the NSS from the Winchester VA place and my friend loved used the NSS(he calls it"THE BAG"! The powernozzle pulled up all kinds of stuff from the carpets.Paper bag was full!!Those can hold several gallons of debris.

So this may not be entirely accurate mostly due to the wand's damage. I did attempt to epoxy it after being shattered in shipping but i can't be certain it's performing as well as a new one would.
The filter was also filthy when I got the thing. Out of concern for it, even after washing it I felt that the filter may restrict too much airflow so I tested it both with and without it.
The suction increased from the machine base to the hose, the reason for that is the empty holes the hose would clip into, they leak when the suction guage is put to the base.
The other thing to note is unlike most machines where I use the full width of the nozzle for calculating nozzle area I decided not to do that here. Why? There's no side air vents on this powerhead there's a lot of dead space (about 2.5") on the sides of the brushroll. Full Width ~12.75"

Perfect C101

The nozzle is awful! It leaks horribly. To my knowledge there's nothing wrong with it. Interestingly I got the same airflow reading with the nozzle running.

An unusual machine

The sanyo transformax uses a turbine head that is, I think, unique to it. The pedal either opens or closes an airpath that bypasses the turbine. when it's open it allows more air to flow at the cost of less force to run the turbine. When it's shut the turbine receives more force but airflow to the surface drops. What I found interesting is that it's an open vane turbine which I have only started to see in recent years. I have to wonder if this is where the open vane turbine started. at least in in a setup like this.

An older Lindhaus

This has been in the works for a while and since I took the time to get it cleaned out I figured now was a great time to do it.

Interestingly despite it's low flow it appears to be a great cleaner as it was also given a 10 pass sand test. Unfortunately after prepping the area I started to clean as soon as the sand was down forgetting to work it into the pile so the bag was removed and re-weighed. After all that I ended up with an incredible 89.6% pickup surpassing all tested uprights so far.
Upon receiving such a high number I investigated by cutting the bag open (picture 2 and 3), we can see that the pickup is a little bit contaminated so it's not quite as high as thought but it still did an excellent job!

Previous testing showed around 50% pickup but I've discovered that during that first test there were multiple issues with the machine. 1. the baseplate was installed incorrectly 2. the brush motor had a worn bearing 3. the brushroll had an end cap full of crap. Since then I've given it a motor and brushroll swap from a donor head it's performing much better now.

So a few notes about this. The nozzle leaks it leaks around the blue band which is for the edge cleaning air channels. I also know I overcalculated the nozzle area due to my inclusion of the channels but I figured it is distributing flow to them too. It did better than I thought it would but I shouldn't be surprised. I guess with the suction numbers I've gotten I was expecting a bit less. Pic 2 for the underside of the nozzle

Kenmore Elite 800 series

We have a new record for canister hose airflow beating out the previous by about 3.61 CFM
With all the joints/connections, and the narrowing airpath we saw a massive loss in the nozzle.

I See A Massive Suction Loss

Which is by design. Still, what a shame to lose that much from the hose to the PN.

From Hose To PN: 90-16=74" Loss
From Wand To PN: 76-16=60" Loss

Thomas Rectenwald's hot-rodded 12A Lux Marquise pulled 91 CFM paired with 38" of suction. It's a real bear to push on pile carpet.

Soniclean!

It's specs are in line with other light weights like the Simplicity S10P or the Oreck XL-21 Though it has a larger nozzle opening reducing the concentration of it's airflow.
