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
HI JRH,
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 JRH, thanks for the information today, I have discussed with one of my friend today, so far I am using one cord on my machine, and one cord for mytee heater, future am looking to add a air hog because always want to be like a ETM one day, and if I have change all vac motors, end up having 2 cords on the machine, + one cord for heater and future another one for air hog, which make something impossible and not worth it, maybe I will just stick with what my machine current situation and save some $$ for air hog haha ...

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 .
vacs are new Jim , i would say the 5cfm difference or so would even be within the margin of error of my little test , the point was there was no real difference between the two .
So not worth the extra weight , fitting hassle , and in the 240v version , extra expence of the 8.4 over the 6.6 . Some (you might know ) are charging almost 400usd !!! for a replacment 8.4 in a certain machine in the UK . The 6.6 we can get for about 150usd .
I agree with u .... marketing ... 8.4 sounds more powerfull that the smaller sizes

Did you get a TM ?

Hey , thats an optionfor you , Personally i think a more powerfull base unit is a better option . Yours is very weak as it is . Its far easier many times imo to bring the portable close to where your working than running hoses and extension cables to the van ... and you still have setup the airhog ..which is almost the size of a portable anyway .

I might get a new machine one day and still keep the air hog

I was planning on fabricating my own ETM with a generator but the wattage and weight was going to be way too crazy. Maybe when i have some extra money and a different van i will give it a try. I have a chevy city express which is basically a nissan nv200

Between the 6.6 and 8.4 we agree. If you can check the amperage between the 2. I found a slight difference . Even a small amount of less amps in the states in a plus.

No TM . Had ONE job over 150' since 2009. Good with what I have.

Did add a 13" Zipper, Cimex and a OP machine to my arsenal.

My Nautilus leaks water through the exhausts and it's getting annoying. I used deformer in the waste tank but it doesn't help. I notice it starts leaking when the waste thank gets fuller, the APO kicks in but by that time leaking has already occurred. Can the APO be adjusted so it kicks in earlier? Is it a good idea to adjust it?

Powder defoamer? Its faster. Check and see if in coming water is splashing stacks. May need to tweek something a little.

After you use it for a while you will get a sense of how many rooms you can do before it gets full or solution tank gets empty.
What are you cleaning with to make so much foam? And how much are you using of each? I dont use the apo, i have 1 white bucket (clean)and 1 black bucket(dirty water)..everytime i fill i dump it and add defoamer and start again.

I that particular occasion when the above photo was taken I used Robs Secret formula and was rinsing with end zone, 300 psi.

Used the dilution on their directions.
Do you think foam is causing the leaking?
That's the first thing I would check. Add your defoamer to the tank and do everything you normally do. Clean 1 room, turn off the machine and check the tank for foam if the defoamer is working you shouldn't see any foam. The only time my machine fills up so much that it comes out the exhaust or bottom is when I finish a job and vacuum out the remaining solution out of the tank. If I dump 1 bucket and then vacuum it out it doesn't do it. During normal cleaning, I don't have any problems. After the job I let vacs run for about a min. covering and uncovering the hose to clear any remaining water in the hose and to blow any moisture thru the system.

Also, make sure there isn't any hair or debris the rubber float that's suppose to come up to protect the motors

Is the pump out activated by water level, or is it a continuous pump?
This is what the manual says....The Waste Pump uses a float switch and does not start pumping until the water level in the tank is high enough to lift the float switch. The pump will turn ON & OFF during normal operation. Pump will be damaged if allowed to run dry.

Which pump does it come with?

I wonder if they could put a smaller like 3.5 gpm pump in that pumps continuously? Or is that something I would have to do myself....
I'm just concerned about weight, have you ever had to carry it up any steps? How much does it weigh?

the machine weighs about 165 empty. I occasionally have to take it up steps, not too often. If you wanted to change it you prob would have to do it yourself. I have never used mine if I had auto fill and the chemical metering kit I would. I may look into it
