Games? We here at MB have no sense of humor - that we are aware of...

Dumb question alert......is that a gauge that tests at the tool?
I'm 15 at the machine but would love to know where I'm at at the tool.

I see a vac gauge that's blurry hitting 23 hg's, where's the 450 cfm?

Bahahaha! I just realized how stupid my question really was, as I didn't notice that was a video...lol. I'm a blonde trapped in a brunette body.

It covers the end of the hose where the tool would go. Measures sealed vacuum (it plugs the hose end so no airflow). It provides some info, but not really indicative of performance when no other info is measured...
When the hose is sealed, with no airflow, the vacuum reading is the same at the hose end as at the machine. This gauge won't tell you what the vac is at the tool, since the tool is removed and no air is flowing (as it would be under real-world conditions).

Ok....so can someone please school me on the vacuum terms?
I know that my machine should be at 15 inches of lift which it is. But what is hg and CFM exactly?

Hg is the chemical symbol for mercury, and lift (or vacuum) can be measured in inches of mercury, so hg is the same as lift.

CFM, is cubic feet per minute, and indicates the volume of air that is flowing through the hose.

What is the ideal CFM at 15 inches of lift?

Trick question! It depends....
For carpet, as much as possible, except at some level of lift/cfm the wand will lock down and doesn't want to move.
For a tile spinner lock down can be a real problem, why some of them come with an adjustable vac relief
For Upholstery tools you can damage the fabric, they usually include a relief as well.
No easy answer on that one....

And the 15 inches is measured at the machine - the lift will be different (much lower) at the tool, further muddying the waters.

Thank you for the info!
I definitely have to use the vac relief on my spinner lol.

My daughter is a red head. I told her she has blonde roots.
She wanted to start a girl band once and I told her they call themselves the blonde roots.

I have the unit set at -23HG, but It will produce more. Unlike Roots or PD Blowers- my machine doesn't have a stall coefficient.
Besides the first -15HG are FREE, you have to EARN anything above -20HG and my machine crushes that.
Larry Cobb (or any builder)... Can you "Push the Performance" to -23HG in 1.8 sec with 50' of 2" hose?
...and for the record CFM is for the Porty Crowd. It's a LIFT thing, you wouldn't understand.

Here we go again.
If so adjusted, ANY machine could "hit" 23 hg momentarily, as shown.
How do you measure CFM?

I usually tell people it is extremely rare that I have a blonde moment so when I do, it's a doozy!

try cleaning carpets at 23 inches hg and see if you can move the wand. see if your recovery tank doesn't collapse. see if the belts on your machine don't fry, at 14 inches my wand picks some carpet off the floor, at 23 the wand wouldn't move at all. The reason that most machines are set at 13-15 is because that is all you need without doing damage to your equipment or the carpets. Even the big boys like the prochem Everest set the vacuum relief valve at 14 or 15. the larger units are more powerful, not because they have more lift but because they have more airflow (cfm) at the same lift. almost any unit can achieve more lift, all you have to do is crank your relief valve down so it doesn't pop off. doesn't mean you have more power

oh yeah, and by the way, when you seal the end of the hose like that, that's 23 inches with 0 cfm because there is no air going through the hose

This kind of response bugs me. You're saying there's something you know that I don't - but you're not going to tell me. It usually means you don't have a clue. If you're not willing to pass on your vast knowledge to us mere mortals than you have no reason to be here.....

Good post Ron, thank you! That was good info on the lift which I needed to know.

I am happy to report that I no longer have blonde moments - now I have senior moments. Now what did I come out to the garage to get???? Oh well....

you could move the wand with 23 lift, with a glide. More lift is better because it causes a higher flow of air causing better recovery. I think any one arguing the value of higher lift and better cfm is naive. However the problem is the complications involved with getting that much lift. Roots type blowers for the most part do not handle that level of lift well because it causes uneven heating that damages the blower. Roots does sell a blower that will maintain that level of lift but it is super pricey. roots 409 Rgs I believe. There are also some blowers that use water injection to lower the air friction and seal the blower lobes better to allow higher lift. I also believe that you can run two blowers in series and it will produce low hgs without damaging the blower (not 100% sure on that one so don't quote me) Next in line is liquid ring pumps. These can also pull a high level of lift but I have never seen one used in the carpet cleaning industry and Im sure there is a reason why.
With that being said, I would be very impressed to see a machine that pulls 23hg lift at 400 cfm. (not 23hg or 400cfm) It would require at least an 80 hp engine and the blower would be very expensive.

Haha! I think I'm at that point where the two are starting to blend, the blonde moments of pure airhead non thinking moments and then the other moments of

Mr Suk-it has taken to FB to complain about being banned here....lol.
It is obvious from his posts over there that he doesn't belong here anyway.

Yup...I just looked at his FB profile, it's brand new.....
This is a very interesting subject, 23Hg would be awesome but it comes with a lot of setbacks, It would be very hard for operator to use all day long, and it would be very hard on the surfaces it is coming in contact with, more so if heat was also added to the mix.
We are all under vac once we enter this world, we just don't realize it. Atmospheric pressure is greater at sea level vs higher elevations this is why water boils at different times and temps when you are living in higher elevations.
Vacuum is the process of removing the natural pressure or weight of AIR, to make it more simple. The more pressure you can remove to easier it becomes to move something (like dirty water from carpet fibers), but it also causes the things that hold the carpet together to expand thus being very hard on them as well, if you were to enter a 100% vacuum chamber your blood would boil, water also boils under 100% vacuum.
Also 100% vacuum has NO air movement but if a small amount was introduced the particulate would be moved much more efficiently the problem is the system would be very hard to move because of the energy or suck it produced.
Perfect example is even a true 15-16 hg load on CGD carpet even with a glided wand is very very hard to use for any real amount of time.

Lol....he claimed y'all took the video down....Ashley and I just proved him a liar.
Many ? my dual blowers vwtm and said it doesn't work....but the thing is it does, the two blowers vacate the pressure out of the waste tank and out of the vac hose, it may be even better if waste tank was divided yes, but at the end of the hose where you hook the wand, the wand does not realize this at all, believe me it sucks to the carpet and when I first set it up at higher hg....um it was no fun trying to move the wand.
