Can't really tell from the pic but they are prob 3 stage, usually, the last stage is in the manifold. Too bad the bolts won't match up to convert it to 8.4 motors. A set of 8.4 motors, gaskets, and manifolds would be 400-450. Have you ever tried it in series?
Thanks for looking at! I did try in series, but wasn't take any attention on it until I realize I should use parallel for long hose runing, $400-450 is not bad, otherwise I has to spend around $2k for air hog ...

its the same size machine. your pump is different, look at my pic on page 1. if that pump didnt take up so much space. i wonder how much that pump cost. with a little patience you could convert it into a mxe-500

yes, I got you, I just check on steambrite website and they have they 240V for 8.4 vac motor, and only draw 6.7AMP on 240V, which means I will need another cord, so far only one cord for the machine, and

I guess I can possibly adding a auto pump out 0.75amp and auto fill run by tap 0 amp + 8.4 Vac 6.7AMP = total 7.45Amps for another cord

And swap my another old 5.7 vac which I believe it only 3.315AMPs ( 10.03Amp wide open - 3.4Amps solution pump / 2 vac motor) to 8.4 Vac, which another cord will be 8.4 Vac motor 6.7amps + solution pump 3.4amp = total 10.1 amp, I believe it should work ~~

But base on the information they provide for the machine no matter which website, I believe the CFM is 190CFM? by changing to 2 8.4 vac motor, only up to 300CFM, but if I have a air hog which also adding another 100CFM, made total to 300CFM as well, does it sounds right?

I didn't know you had a 1 cord machine. That doesn't seem right at all. a 5.7 3 stage motor usually draws 9.8 amps. an 8.4 motor draws 13.1 amps. How much did you pay for your machine?

I would guess hes based in Australia , to save any more electrical confusion
o_O
Most of their breakers would be 10 amp , equal to about 20 american amps

Easiest improvement would be to import two of the better 1600w conical electros that Mytee use , Larry cob supply sells the 240v version , they would also be around 7amps .
Then convert it to a two cord , one 7amp vac + you pump one cord 1 , the second vac on cord two .
That manifold looks very specific to a 5.7 vac , so you would have major work converting the machine to 8.4 . Also the 240v 8.4 is very costly inmost places . I would use the 6.6 insted if u go that route , easier to fit ,any by my own testing performance is the same as the 8.4 . at least the 240v versions .

thanks! Is this the vac motor you talked about?http://www.this company does not su...n_page=product_info&cPath=86&products_id=5085

links dont work it seems , its called lmb230 on that site , that would be the 7amp
also look at lmb437 ... i believe its1800w so a bit more lift , but its atleast 8amps which may be too close to your 10amp with a pump added .
You could get one of each i suppose also .
dont worry if they are rated 230v if your supply is 240 , all the vacs are rated 220 to 240v

Hi thanks, I just check the the item No. you showed me , and I noticed they are 5.7" vac motor, I was looking at 6.6
LMB6A, as their are 30cfm more than 5.7", one thing I don't am not sure is would 6.6" fit my old 5.7“ vac motor? I know the 8.4" definitely too big in this machine and by you saying the 6.6" are performance similar to 8.4" with less AMps draw. So if the 6.6" could swap the 5.7" then I defiantly give it a plan to change it .

Hi yes , 30 more cfm for the 6.6 but half a Hg less (my testing ) so when the wand is on the carpet the half hg would compensate a bit for the loss.
You would not be disappointed with either and I have used both .
.
I'm not sure if the position of your current manifold would allow custom fitting the 6.6 without mods

Thanks a lot JRH, I defiantly will ask my supplier and either interlink or steambrite if the 6.6" would fit into my machine, THANKS HEAPS!

no problem ,

I have a couple of quick vids from when i compared the 8.4 and 6.6 @ 230v

* The CFM is not calibrated for measurement accuracy and is abit on the low side , its just for comparison from motor to motor .

130CFM for 6.6" looks awesome, recording website information of 8.4" are 140CFM which no big different!

No , dont read the figure as a measurment , the calibration of the meter would determine that , just compare the cfm of each vac ( the 8.4 is there too )
I would say each vac makes 10 more cfm if measured with calibrated test equipment

yes! I saw the CFM of 8.4" was 124only and 6.6“ was 130 CFM WOW

Something wrong with 8.4 . CFM has always been closer to 140 on all 3 I had a chance to test. Stateside
Do agree not a substantial difference in overall performance between the 6.6 and 8.4s except a slight amperage (less) advantage.
Marketing advantage goes to the 8.4 .
