If someone was interested in a new 1005DX with that new 400 psi 1/3hp motor instead of the big heavy 1/2 hp Marathon, would you be able to accommodate the request and cobble one out?

Kevin, you should just hold out until Mytee introduces an adapter for the new 6.6's.
Total CFM in parallel would be 332, and 176" lift.
It would be an animal of a machine.
I am not sure of calculating lift in series, but in series, CFM would remain 166, with ? lift.

Sure, we have used both of these configurations successfully.
The 1/2 HP motor has a big advantage in being able to do Grout & Tile work
with a Turbo Hybrid @ 1.5 GPM.
We think Hi-Airwatt extractors able to do carpet or Tile/Grout @ 500 to 700 spraying are the machine of the future.

Still right on the cusp of what would be considered minimum effective psi for t/g I would think.
Hopefully a lot closer to 700psi than to 500.

Well if the CFM would be 332 and lift 176 i'd agree that would be awesome , but according to larry on that mosquito machine with the duel 6.6 mtrs duel stack parallel the CFM is 270 and lift 135 how did you come up with your numbers

Skeeter is not using the same 6.6"s that Larry has formulated I believe.
Larry Cobb

You are correct. The new AirWatt vacs are more powerful.
The lift on two of them in series is 176". CFM is over 166.

Larry, can you clarify this........
As far as I understand it, when calculating the total cfm and lift of two vacs in parallel, the total cfm of both vacs is added to each other, and the lift total is equal to the value of one vac.
When in series, the cfm total of the two vacs is equal to the cfm of one individual vac, and not a cumulative total as in parallel.
So when in series, how is total lift calculated?

In discussions with the two major vac motor manufacturers,
the only accurate method is actual lab testing.
With older vac motors,
a rule of thumb was series vacs added about 60% lift, and parallel added about 5-10% CFM.
More modern tapered fan vac motors have improved the numbers slightly.
Of course, in a extractor, electrical voltage, plumbing & vac hose (CFM) detract from those numbers.

So based on this info, this unit that is using your "proprietary" 6.6" motors in series is achieving appx 170CFM, and appx 280" (176+96) of lift?
Not too shabby.
If someone was to sacrilegiously use these proprietary 6.6" motors of yours in a parallel configuration against your wishes, they would achieve appx 330 cfm, and lift would remain 176.
So you believe that an additional 96" of lift is more of a benefit that an additional 166cfm in this example.
170 cfm 280" lift in series
vs
330 cfm 176" lift in parallel
Your going to have a hard time selling anything other than those sweet parallel specs.

Total lift with 2 of these vacs is 170" .
I'm guessing they are 110" of lift each.
So the Series spec is ~ 180 CFM with 170" of lift
vs
Parallel 340 CFM with 110" of lift.
The key is that the lift and CFM drop less with these AirWatt vacs than other 6.6" & 5.7" vac arrangements I have tested.
Most of the customers testing the new Breeze state that it feels like a entry-level TM.
I do have a manifold that will series mount 2 of the new vacs with no connecting hose:

...and parallel will double the cfm, but no additional lift?

Pure BS!They have never used an entry level TM or they wouldn't clean with a portable.

I'm just baffled this is 9 pages long.. Reminds me of when you buy a computer, the day after it's obsolete..
67% more of crap is just more crap..

I actually agree with this, but it feels comforting to make excuses. So nyah.
Spewing out stats is all BS. Kind of like all of those VLMers defending their method. It seems like all the porty guys really over think this. I've seen all of the videos of porty guys running multiple cords adding this doo dad and running this cord over there bla bla bla. And unless you are cleaning high rises all day and that is the only way then your mind is warped for thinking any portable is better than an entry level TM.

Jimmy;
I never said it was equal to an entry-level TM.
Good TM's have heat !
The vacuum level at the end of the hose is what i was comparing too.
Portable with 25 ft. of 2" hose . . .
TM with 100 ft of 2" hose . . .

Five gallons of gas in the solution tank and a match. Hopefully, your 16 inch pos castex wand is nearby as well.

If it is a 7.2" diameter vac, then the best upgrade is this new 8.4" vac:

Here's a new idea to include on portables: a tiny float in the fresh water tank so it shuts off instead of pumping itself dry. The 2lbs of float would be well worth it. I hate it when I run it out of water. It's hard on the pump and wastes time re priming.
Can't you hook up a water hose? If not, I'd invest in a setup where you could

Why not a simple toilet float? Bracket to hold it at correct height in tank, top-mounted hose connection and voila!

Don't use a toilet float.
We use a General brass Float Assembly that handles 160' hot water, adjustable level, and can be rebuilt:

IF it were true Stephen there are still so many factors that make a portable a poor comparison to a TM, even an entry level one.
Setup time:Finding sufficient outlets to run the power required takes time to make sure you are on separate circuits.
Professionalism: Do you think this is really what the client thought the process was going to look like when they called to have their carpet cleaned? Black spaghetti?
Dry Time: Added humidity to the indoor environment via the exhaust from the vac blowers hinders the drying time.
Contaminating the Indoor Environment: Any urine, animal, vomit or other nasty containment is going to be redistributed back into the home only first heated up and then spread back into the home.
Cleaning Time: The ole Bucket Brigade is slow and inefficient. You're eating up the clients time when the TM cleaner would already be down the road
Slow Production: Because of all the above it actually affects your pocket by limiting your per hour production. Portables aren't actually cheaper, they cost you more money!
The only factor that gives the purchase of a portable the upper hand is purchase price.
