I recently purchased a Kirby Sentria and it's become my favourite upright.

I am thinking of importing a Metal Royal to add to my collection.
How does the Royal compare to the Kirby?

I have heard it has a very aggressive brushroll and is as noisy as a jet engine 😂
Would love to hear your views

I personally cant stand the new royal in fact I have a one of the new pro series metal uprights and i never touch it. Its noisy and not of the fit and finish a Kirby is. Personally I'd stay away.

Marcus,

The Royals are very nice machines. They are more simple and don't have the bells and whistles of the newer Kirby's. There's no Tech Drive and no belt lifter on a Royal. In fact the floor nozzle is not removable on a Royal. There is a hose adapter that allows you to use attachments. It connects through the Adjust-O-Rite opening on the front of the nozzle but you have to manually remove and replace the belt. Overall it is a very rugged and sturdy well built machine that will last as long as a Kirby. The early Royals (1950-1990) had 4,5,6 amp motors that were not very loud but cleaned as good as a Kirby.

 

There is one thing  you will like about a Royal - The Nozzle size is only 14 inches wide which makes it highly maneuverable around furniture etc. 

 

The newer Royals (1990 to present) have 7,9,10 amp motors and are much louder, a little bit louder than your Sentria II. I have a Royal Everlast 8300 made in 2008 that has a 10 amp motor. It is slightly louder than my Sentria, but it will definitely OUTCLEAN my Sentria. The brushroll on most models has stiffeners which act like beater bars. It also sucks down to the carpet which makes it harder to push and pull. I have a bad back so I would much rather use my Sentria with Tech Drive. I pull out my very powerful 10 ampl Royal Everlast about once a month or when I really want to Deep Clean my carpets.

 

Here are some pictures of my Royal Everlast 8300:

Thank you for that Stan

So your Royal will out clean a Kirby? I'm surprised you said that 😱

The 9, 10 amp models are only slightly nosier than a Kirby?
Maybe I'll import one then.

I like BOTH the Royals and the Kirbys-do think the Kirby has more airflow than the Royals-the Kirbys have the larger bag fill tubes and bag horns.Would like to put a Kirby tube and horn in a Royal and see how that works!I have several Royals-could use one for the Mr Wizard experiment.The Kirby G series are quieter than the Royals 9,10 A machines.

I have used both

I LOVE the early Royals and Kirbys, but don't really like any of the newer ones, The Kirbys after 1969 are too big and heavy, and the Royals after the 801 just don't feel the same.I personally don't want or need a upright that tears all the nap out of my carpet and sounds like a jet...LOL

That's always a concern with a very aggressive brushroll it can wear out your carpet prematurely. You need to find the sweet spot between maximum pick up of dirt without damaging the pile of the carpet

You can take agitation too far.

I will have to disagree with Tolivac about airflow. My Royal 8300 has more airflow than my Sentria. I have measured this by putting my Baird meter at the end of the hose of both machines (my Royal has the optional Hose with attachments). My Sentria pulls about an 8 on the Baird, but my Royal pulls about a 9.5. Keep in mind that I am talking about my 10 amp 8300. Royals with motors smaller than 9 amps will not outclean a Sentria.

 

If you don't have a Baird meter it's still easy to tell by removing the inner paper or cloth bags from both machines then turn them on and hold your hand about 6 inches away from the fill tube opening. I can easily tell that the Royal has much more air pushing against my hand.

 

About Royal brushrolls: When I examine the contents of my Royal's cloth HEPA bag, I can find no carpet fibers at all, just dirt and cat hair. This is because the Royal brushroll has very soft and fine bristles, much softer than The Sentria's  fairly stiff bristles. The plastic brush stiffeners on the Royal brushroll act like beater bars, which the Kirby doesn't have. As far as carpet shredding goes, have you ever seen a Hoover Senior or Convertible or a Sanitaire destroy carpet fibers? No. The Royal brushroll acts exactly like the ones in those Hoovers and Sanitaires. Soft bristles and stiffeners do not destroy carpet. You can search the Vacuumland archives and you will not find any posters that say their Royal is shredding or destroying their carpets.

I would like to import a metal royal but with shipping import taxes and having to buy a step down transformer plus the 2 HEPA bags plus shipping to the UK will cost me 30. If I lived in the US I would definitely buy one but importing one to the UK looks uneconomical to me sadly. 😞

Royals

Have always moved more air, but they did not seal to the carpet like a Kirby so it seemed they didn't.,,They used to advertise that the curved fan blades moved more air with less amperage.

So if the Kirby seals to the carpet better it's going to have more airflow at the floorhead where it's needed isn't it?

I used to own a late 90's or early 2000's Royal Commercial 10 amp (I regret giving that away) and I used to own a Ultimate G that I just recently got rid of. I definitely liked the Royal a lot better than the Kirby, it had better agitation and it felt like it moved more air than the Kirby. I liked how much more simple it was just like what Stan said and it also felt lighter than the Kirby.

Both Kirby's and Royals seal to the carpet!

 

The Royal has the Adjust-O-Rite indicator on the front of the floor nozzle. As you adjust the nozzle down to the carpet, the button on the front of the nozzle sucks in to indicate a proper seal to the carpet. 

 

The Kirby's proper height is determined by lowering the nozzle one more click after you hear the brushes contact the carpet. So you see both machines have a method to determine when you have a proper seal.

 

The 10 amp Royal will have more airflow at the floor head than the Kirby. If you compare the fans of both machines, you will see that the blades of the Royal's fan are not only much more curved than Kirby's fan, but in my opinion it's that the Royal's fan blades are quite a bit taller or deeper than the Kirby fan which means it scoops more air per revolution than Kirby's fan. The Baird meter proves this.

 

I have proven that the Royal cleans better with this simple test: I spread about 1/2 cup of coffee grounds on my light beige living room carpet. I run my hand back and forth over the coffee to push it deep into the carpet pile. I do this for each machine. I then run each machine one pass forward and one pass back. My Sentria leaves a few coffee grounds behind, But my 10 amp Royal 8300 gets it all. Nothing is left behind. My Sentria needs to make a second pass to get the rest.

 

Don't get me wrong, I still love my Kirby Sentria more than my Royal because the Sentria has Tech Drive and also seems to be smoother, more balanced and more of a joy to use than the Royal. Keep in mind that there is only one vacuum cleaner that can outclean a newer G series Kirby, and as far as I know that is only a 10 amp Royal.

Stan, Here's My Baird Tests To Date

wyaple's profile picture
You'll notice that the G5 and Sentria II both pull 10's from an outstretched hose with fresh HEPA bags installed. If your Sentria I scores a 8, something is amiss.

BUT, your claim of fill tube (exhaust) airflow is very interesting. Using a GM8901 anemometer I found that:

Kirby Heritage II Legend (low speed) = 153 CFM
Kirby Heritage II Legend (high speed) = 182 CFM

Kirby G5 (low speed) = 174 CFM
Kirby G5 (high speed) = 191 CFM

Kirby Sentria II (low speed) = 157 CFM
Kirby Sentria II (high speed) = 195 CFM

My Sentria II does 137 CFM at the nozzle with the brushroll on and HEPA bag installed. If I turn the Tech Drive off and the height adjuster is properly set for medium pile carpet, I can barely move the machine. My older Kirbys (G6, G5 & G4) only do 120 CFM at the nozzle and that 17 CFM drop means the older G's are moderately easy to push with the power drive off. I couldn't imagine a non-power drive, carpet nozzle sealing machine with more airflow because I would think it would be impossible to push on standard carpet.

Maybe there really is quite a difference between a Sentria I and the newer Sentria II/Avalir?

Bill

Bill,

 

I will have to admit that when I performed those airflow tests about 2 years ago, I did not have brand new bags installed in both the Sentria and the Royal. So today I replaced the bags in both machines with brand new cloth HEPA bags and repeated tests.

 

The Sentria pulled a 9.5 at the end of it's 6ft hose'

The Royal solidly pegged the meter at a 10 with it's 8ft hose. If the Baird meter scale went up to 15, I wonder how much higher it would register.

 

I'm not sure why your Kirby tests varied so much. As far as I know all of the G series Kirby's have the same 7 amp motor. The only variables I can think of would be the type of fan installed or differences in the outer bag materials and/or construction.

 

I am quite sure my Royal has considerably more airflow than any Kirby. I wish I had the tools to measure CFM.

 

I welcome your thoughts on this.

 

~Stan

Afterthoughts...

sptyks's profile picture

Bill,

I was thinking another reason why your Kirby airflow tests varied was the different style mini emptors Kirby used over the years.

 

You mentioned this:   " I couldn't imagine a non-power drive, carpet nozzle sealing machine with more airflow because I would think it would be impossible to push on standard carpet. "

My Royal is easier to push than my Sentria is with Tech Drive off. I believe the reasons are because it is a few pounds lighter (15.5 vs 23 lbs.) than the Sentria and also the stiffeners on the brushroll tend to propel the machine forward. If I let go of the handle the machine will slowly move across the carpet by itself. You might think that it is not really sealed to the carpet, but the fact that the Adjust-O-Rite button sucks in proves a proper seal. If there were no seal, the Adjust-O-Rite button would not get sucked in.

Stan,

wyaple's profile picture
Is your Sentria 1's hose length really only 6 ft? Here's the lengths of my Kirby hoses. I was surprised that they varied so much actually.

Sentria II = 7.5
G6 = 8.5
G4 = 8.0
Heritage 2L = 6.5

As far as Baird readings go, I found out that much above an "8", the meter goes non-linear as the below graph shows because the spring is stretching too far. So the difference between an 8 and 10 is only about 5 CFM. My Sentria II actually snaps the Baird meter past a 10 via the hose and my anemometer reads 120 CFM from the end of its outstretched hose.

The Sentria II apparently has about 17 CFM more airflow than previous models due to a slightly stronger motor (I have current tests that prove this) and a newer one piece emptor and fill tube. Kirby is always tweaking their designs, albeit very slowly.

I will reiterate what I've said before. At 137 CFM, my Sentria II is almost unusable on medium pile carpet with the Tech Drive turned off. If your Royal has significantly more airflow, how would you be able to push it? I would LOVE to see 150 CFM from a carpet nozzle, but I'd bet it wouldn't move after the seal was properly created.

Of course, measurements speak volumes to me and if I have a chance to obtain a newer Royal, I certainly will. What I suspect is this. Up through the Sentria 1, Kirbys appear to have maxed out (using HEPA bags and the newer Amodel fan) at around 120 CFM at the nozzle (@120VAC). From the Sentria II forward, Kirby made some improvements that have yielded about a 14% increase in airflow. My water lift tests haven't yielded any significant difference since my G4.

Lets just say they both have enough airflow and agitation to clean carpets very well and are hard to beat. :-)

Look Like We Had Some of The Same Ideas

wyaple's profile picture
Regarding the emptor and fill tube changes. :)

Regarding the Adjust-O-Rite settings you said,

"If I let go of the handle the machine will slowly move across the carpet by itself."

That more or less means to me that the Royal is NOT sealed to the carpet. Otherwise, wouldn't it just sit there (kinda like a plunger?) The Adjust-O-Rite plunger is set to "pop" a some preset level, but we don't know what that is, right? It could be satisfied with 60 CFM pressure or 80 CFM pressure, we dont' know...

The two vacs I've tested so far that "self-propel" without a power drive have dramatic CFM losses at the nozzle. Look at my "airflow losses" posts for the Panasonic MC-UG589 and Simplicity Symmetry.

If you want to see a true test of deep cleaning, get a patch of medium pile carpet and put a small amount of flour under it. Then in just two complete passes, look at what's left under the carpet. If the flour is mostly gone, you have a machine that has a good seal and great CFM.

You know, now that I've mentioned that "under the carpet" test, I think I might test all of my machines and post the results when time permits...

Bill

I thought that. If it's self propelled by a very aggressive brushroll it can't be sealed very well and will lose airflow at the cleaner head.

Yes, when you're talking about triple digit nozzle CFM, you are automatically in a class that sets itself apart from everyone else! No Dyson or Rainbow can do that.

Will the action of the brush stiffeners that act like beater bars prevent the floorhead from making a good seal? I may be wrong I usually am 😁

Post# 368999 , Reply# 22   3/23/2017 at 14:56 by wyaple (Pickerington, OH)        
Yes, you are correct

wyaple's profile picture
I have 4 different types (grades) of Kirby brush rolls and they change the forward bias of the machine slightly. With the stiffest one (152505), you can definitely tell the nozzle rises up very, very slightly and wants to move forward more easily. Of course, no Kirby brush roll makes the machine move by itself...

With the oblique softer bristles (152502), my Sentria II gets noticeably quieter and the very slight forward rise and pull mostly go away. It pulls up less carpet fibers too.

First off, The Royal is significantly lighter than Kirby G series machines.

 

Second, If the Adjust-O-Rite button sucks in, there must be some type of seal going on, otherwise the button wouldn't move. This button is connected to a metal diaphragm inside the AOR cap. There needs to be some type of seal in order for there to be enough vacuum to move the diaphragm 1/2 inch.

 

Third, Bill how are you adjusting the height of the Sentria nozzle? Are you going the one click after the brushes contact the carpet, or are you going lower? In order for my Sentria to suck down to the carpet so tight that it is very hard to move, I need to go two clicks past the brushes making contact for it to be difficult to move.

 

Lastly, You NEED to try a 10amp Royal in order to experience what a powerful machine it truly is. I tried removing the belt from the motor shaft. When I did that the Royal was very difficult to move. After putting the belt back on I performed the following agitation test: I sprinkled a handful of oatmeal on the carpet then I slowly approached the oatmeal with both machines, When I did that with the Sentria the oatmeal started bouncing around when the nozzle was about 3 inches away. When I approached the oatmeal with my Royal it started to bounce around when the nozzle was 10-12 inches away. There are videos on YouTube that demonstrate this. That's where I got the idea to see if my Royal could do this and it does.

 

Final thought: What this really all boils down to is not how much of a seal each machine has, but which machine is the better carpet cleaner! Bill, I hope you can get our hands  on a 10 amp Royal so you can do measurements and .get to experience it for yourself.

Stan,

wyaple's profile picture
I'd love to get my hands on a newer Royal...haven't seen any around my neck of the woods in years though, but I'm always on the lookout!

And I adjust all my Kirbys exactly as the factory recommends them. :)

That's a lot of agitation from your Royal. Bouncing a whole foot away is tremendous! BUT, I'm not very impressed in how well surface litter is picked up, only how deep ground in sand and dust can be picked up from the very bottom of the carpet. I've tested all my machines and the Sentria II has so much airflow that flour sprinkled UNDER the carpet (brand new Mohawk medium pile) gets sucked right up in a couple of passes.

You know, it's too bad that 99% of the world won't know or care about high CFM machines. The vast majority seem relatively happy with their 80" water lift, 70 CFM sub-$100 plastic bag less vacs. :(

Bill

The beater bar action of the brushroll stiffeners prevent the royal from making a tight seal to the carpet. The cleaner will move forward on its own that proves it's not making a tight seal. It's has better agitation but because the Kirby has a better seal at the floorhead it will suck in more dirt.

Royal Everlast 8300 10 Amp Efficiency

wyaple's profile picture
I have seen on YouTube (vacuumcleanermuseum's channel) that the 8300 pulls about the same on a Baird meter as an Avalir (my Sentria II matches these figures). The tester should have stretched the hoses out straight but at least they were wound around approximately the same.

One concern I have is airflow efficiency from the Royal. Even though it may have similar airflow to a Kirby, the Royal is massively more inefficient.

Example:

Sentria II (hose mode) = 6.74 Amps @ 120 Volts = 809 Watts
Everlast 8300 (hose mode) = 10 Amps @ 120 Volts = 1200 Watts

That's about 400 Watts more (48% more) needed to produce the same airflow. I'm surmising that the Royal has a much less efficient motor/fan setup than the Kirby does.

I still want one because they are very cool machines! When I get one, I'll be sure to post the full tests and add it to my growing database.

Perhaps apples and oranges here, but I do have both Royal and Kirby, though the Royal is older 880? I want to say 7 amp, with stiffeners and Kirby is Diamond, standard brushroll. I have a dark area short nap rug in front of litter box in garage space, over another rug, so the dancing of litter is very visible. I lowered Royal and nice dancing a foot away from nozzle , Kirby, over 2 ft away! Dyson 18 standing by? 3". ops. I tried the flour from under the rug inside house, but perhaps too tight a weave synthetic rug, neither pulled it through the weave, but the Kirby did pull several inches of it off the floor, royal just the edge. No help perhaps, but more info anyway! Love them both.

Great....

thread! So much more interesting to have real CFM measurements. I just bought a Royal 880 to restore. I will never buy a Kirby for petty personal reasons...that have to do with Kirby people in the past and not so much about the machine, although it's heavier than anything I want in an upright.

 

If the 880 can at least vacuum better than the Hoover upright I had in college (and really liked) then I'm set. I've mourned the loss of that Hoover ever since I got into Elux canister collecting. There's just something about pushing and pulling a good upright versus dragging around a canister & PN.

Makes sense. I have the smaller amp motor in my 1975 880. Almost immediately, I got 'amp envy' after reading about the more powerful motors that came later.  But, we'll see how she does when I finish restoring her. Like I said, if she aces the old Hoover, I'm set....lol.

 

Like the discussion about Royals in another thread....I don't understand why they didn't go with polyurethane type wheels like skateboards did in the early 70's, instead of those dreadful, Bakelite type wheels they used for so long. If it's possible to find, I'm going to put skateboard wheels on the 880 of the same width and height. I've seen some longboards with very similar sized wheels and some graphics on the wheels would only add to the fun.

I modifiedd one of my 1028 Royal commercials to use a Kirby F-Fit bag tube and horn.Using the Ultimate Filtration Kirby Filtrte bags in thagt Royal now.There is a difference in the Royal-had to Raise the nozzle all the way up on the Rite Height dial.The machine p[ick up without any hesitation as wioth the older Royal paper bags and feed tube.The Royal tube was constricing the 10A Royal airflow.I have some Baird guages in my Kirby saleskits-but don't haved the holse adaptor handy for the Royal.I use the Kirby and Royal in upright modes only./i have other canister cleaners that I use-esp the MD cengtral vacuums.Will use my modified Royal some more.Like the Kirb y conversion.The KMirby bags are easier to get.

Royal wheels...

sptyks's profile picture

Kevin,

 

Royal wheels are not made of Bakelite. They are made of the same material as Bowling balls are so as not to scratch wooden flooring. The material is like a very hard rubber that has a little bit of give to it.

 

The wheels are very wide so the Royal does not sink into the carpet. When I push it with the motor off, it feels almost like it's gliding on air. It is so much easier to push than my Sentria. It kind of feels like my D50 only with 3 times the power.

 

I don't care how you compare it to Kirby measurements, the proof is in the pudding. The Royal cleans carpet as well or better than Kirby!

Stan...

it was stated recently on a Royal thread that they were Bakelite-isk wheels. Another member said that he had a Royal locked in a car with closed window(for storage) over the hot summer....and that the wheels themselves literally disintegrated from that hostile environ. I just question the use of wheel material given that urethane wheels are virtually indestructible and relatively inexpensive.

Royal vs Kirby Airflow test

Hello everyone,

 

I just ran across this video of what I believe is a Royal Everlast 8300 and Kirby Diamond battling against each other over an empty paper towel roll. See for yourself which machine has by far the most airflow.

Stan that is because the Kirby is dealing to the carpet there is very little air being pulled in from outside of the floorhead. The royal doesn't make as tight a seal so more air is being sucked in from outside the nozzle that is why it wins this test

Even.....

on a hardwood floor, wouldn't the height adjustment have something to do with the tug-o'-war? I don't think that makes a fair comparison of the two machines.

Stan,

You're probably right in this instance. A 10 year old Diamond with 120 CFM up against a current model Royal. BUT, try that same test with a 137 CFM Sentria II or Avalir and see what happens...

And that's only an approximate test of "bare floor paper towel tube airflow" not sealed to the carpet airflow. Remember, vacuumcleanermuseum's channel shows that the Avalir has slightly more airflow through the hose, so it probably comes down to what kind a seal both machines have with the carpet.

Royal 8300 Hose Airflow




Kirby Avalir Hose Airflow




I just tested my G5 (125 CFM at the nozzle) and it picks up the edge of my medium pile test carpet (5'x7') four inches off the floor with the brush roll spinning and six inches off the floor with the brush roll off.

Now I'm really looking forward to grabbing a 10 Amp Royal. :)

Let's see, the Diamond handle and a Diamond bag...doesn't that mean it's an Ultimate G Diamond? Am I losing it? :)

In that video it looks MUCH older, look at the emptor. Also we have to remember the Kirby is running on low speed for floors, Royal I am pretty sure is fixed speed.

So that video shows the Kirby has slightly more airflow than the royal and the Sentria 2 has slightly more airflow than the Diamond.

Just looked at the royal website. The Metal Royal gets a CRI "silver award" They must have used a HEPA bag so it's comes down to carpet pick up. The Kirby gets a "Gold award" and as you said previously Stan they might go up to a platinum award which would put the Kirby even further ahead.

Only 2 canisters

I have ever seen that would pull the Baird indicator as far as it would go, The Sunbeam Dual Deluxe and the Apex Strato Cleaner.

Marcus,

 

Your Reply #39 makes no sense. Both machines are on hard floor not carpet. This test is for pure airflow without any carpet involved. It shows that the Royal moves more air period.

 

And as far as CRI tests go, the Royal got a Silver rating not because of cleaning ability, but because filtration was not as good as Kirby. The reason is that at the time of testing the Royal had a paper bag installed in it because the Royal cloth HEPA bags were not yet available at the time. The paper bag was the reason for the Silver rating. I read this somewhere online, but I don't remember where I read it.

 

Kevin,

If you expand that video in Reply #38 to full screen and look closely, you will see that both machines are at the same height. The distance between the nozzles and the floor is the same. Again, it clearly shows that The Royal moves more air.

 

Bill,

 

In your Reply 42, it looks to me that the Royal had a paper bag installed which may be why the Avalir won by a half of a point on the Baird. The Royal cloth HEPA bags are not only hard to find they are also expensive for a 2 pack of bags - about $15.00 for 2 bags.

 

Here is another airflow test this time a Sentria II with 7 amp motor and 11 blade fan against an early 90's Royal with 6 amp motor and 6 blade fan. As you can see the older Royal holds it's own against the newer more powerful Kirby:

Oh well if it has more airflow than the Kirby then good for Royal.
The Kirby cleans well enough for me.

If royal did decide to export I'd buy one but they haven't in about 100 years so I doubt they ever will 😣 Silly really cause they cud increase their profits!

Marcus,

 

 I'm guessing but Royal / TTI probably does not want to export because of the cost of starting a separate production line with 220 volt motors and different cords and plugs. There's also the fact that Europe and UK prefer canister vacuums over uprights.

 

This has no bearing on the above, but Royal production has moved from China back to the USA. Production is now located in Louisiana at the old Oreck factory.

Don't royal have a commercial cleaner that has a gold award? I don't think that had a HEPA bag fitted did it?
Hmmmm are the CRI tests to be trusted?

Kirby and Royal do not filter the carbon dust from the motor so how they would pass a filtration test I don't know.

The Sebo X4 has a good pre motor filter but because the post motor filter is just a foam pad carbon dust escapes and it gets an F rating in the EU which is poor.

Wasn't the Pro-Series model going to be discontinued anytime soon?

Yes, CRI does test every cleaner for filtration of  bags and filters. Carbon emissions are not tested because they are not only a very miniscule amount, but carbon is not allergenic like dust is. People are not allergic to carbon because, other than water, your body is made up of mostly carbon.

 

If you ask me your government vacuum tests are ridiculous. They seem to be non standard because the manufactures are allowed to do their own testing.

The cleaner is put inside a sealed container. Anything that comes out of the cleaner whether it's house dust or carbon dust from the motor will show up on the test as the Sebo X4 does.

I spoke to the MD of Kirby UK. He told me there are 4 designated testing sites and when the test is done the manufacturer is not allowed to be present.

He told me they sent a Kirby to be tested but they weren't happy with the results. He said they couldn't have set the Kirby up correctly because the results were worse than a Sebo. He said that's crazy because a Kirby comes nowhere near and they pulled out of the test.

The point i'm trying to make here is for instance a Miele has a post motor HEPA filter so when this cleaner is put inside the sealed testing unit nothing will come out of the cleaner and in the EU it gets an A rating for filtration.

The Sebo X4 has an S Class pre motor filter which is very good but when this cleaner is put in the sealed unit carbon dust is escaping from the motor and these particles will register in the test so the Sebo gets an F rating. It's not household dust escaping it's carbon dust.

If the Kirby or Royal were placed into the sealed container they would also get an F rating for filtration for the same reason as the Sebo so how did the CRI give it a gold award for filtration?

All,

wyaple's profile picture
Please take a look at my toilet paper roll test and conclusions. Because the roll is VERY light, it is also very sensitive. This is bad because just a few CFM difference can make the roll stick to the winner's vacuum. I have proven a 4 CFM difference is all you need to "win" this challenge. When I have time, I will see if a piddley 2 CFM difference is all you need to win. Considering we're talking about CFM's in the 140 range, just 2 CFM wouldn't amount to very much.

A BIG difference

Between Kirby and Royal, is the height adjustment, the Kirby adjusts on the FRONT wheels, so the nozzle remains more level, thus the nozzle seals more firmly to the carpet, the Royal adjustment on the rear wheels, thus the nozzle is tipped more so it gets more air from the front.

Production for what TTI makes in America is located in Tennessee not Louisiana.
