Thread: M5 or less??

If you are set on the M5, keep looking until you can find a good deal. There should be a supplier out there that will throw in the M5 with all the accesories. If you go less, you will be worrying about it later.

Where are you located?

What if you could build one of those lesser machines(1000DX or 1003DX) to perform better than a M5?

Just some food for thought, and it can be done.

The vac motors that Mytees uses in the M5 are the C302A 3 stages. They're listed to have 115 CFM and 148" of water lift.

The pump is a 205 series Pumptec pump head with the 1/3 hp M4 motor. That combo generally uses a 125 eccentric offset cam bearing to produce 1.25 GPM at 500 psi. Although Mytee uses a regulator to keep it at 450 psi. That motor will also draw about 3 amps during use.

Now, you can go bigger. You can use the same 205 pump head with the 1/2 hp M58 motor. It with draw about 5.2 amps, however you can bump up to a 160 eccentric offset cam bearing to produce 1.6 GPM. The beauty of this set up is you can use 4 jet wands, with four 01 jets, with out a drop in pressure when you key your trigger. Or, you can use a 2 jet wand with two 02 jets and get the same result.

Here's a pic of a Speedster that I've done the M5 upgrades to, but it has the custom pump in it. One thing you can do is also vent you exhaust out the back like I've done. I'll be making a booster that can good directly from the machine for a ridiculous jump in lift.

Where do you buy the vacs and pump if one was to do this, and how much? I have seen a bunch of used speedsters around CL and this sounds like a good plan.

ATS Marketing sells pretty much everything you'd what to do an upgrade like this. I got my Pumptec parts from ADCO Pro. However, I would do some shopping around to get the best price.

Here's ABOUT what I spent on the upgrades to my Speedster.

$130 per vac motor
$500 for my custom Pumptec pump
$30 adding another cord
$50 Misc brass fittings
$100 Extra hardware and wiring

About $1,000, so a lot of people would argue, "Why not just buy a new machine?" Well, if you have the extra grand burning a hole in your pocket it might be worth it. However, I did mine in increments when I could afford the extra parts here and there. Personally, I have no regrets. This thing is ridiculously better than when I first bought it. I've looked at A LOT of machines out there, I didn't really find one that I thought would work for me. So, I built my own.

I still have the old 2 stage vac motors and plan on building a custom booster with them.

So, I'd say if you have a little extra cash and some time, go for it!

Yes, but it would be very tight. The route that I'll be taking is to use a sump type auto dump that goes directly into the waste tank. The pump out that Mytee installs in their units seem to clog up fairly quickly. A sump type auto dump would be better suited to prevent that.

As for the auto fill, there isn't a whole lot of room needed for that, so no real problem there.

That would also do away with heat (without other arrangements) but if the pump OUT worked well, not having the fresh water tank full of water nor the need for a pump would clear up some space for a better do hicky for other purposes.

Now this is just some ramblings by an older beer drinking CC'er who fancies himself as rather smart. This post may prove otherwise.

But look, I use the porty with a 100 psi pump and 11003 (2) jets and surely the PSI is not 100 now. But the flow-rate is and I get good coverage. (In testing out front anyway). Removing a pump would also open up a few amps and a cord.

Now suction is the focus as pump-out. Right?

I can tell you from experience that the difference between cleaning with 100 psi at the jets and 450 psi at the jets is huge. The additional agitation that you get from more psi is unreal when you compare it to a low psi porty. However, most porties don't see their advertised psi at the wand. IE there are a lot of 500 psi extractors out there, but very few maintain steady pressure when the wand is keyed. Most usually drop to 200 psi or below under working conditions.

Now, that's not because the pump is not capable of higher psi, but rather not capable of the flow required to maintain that psi.

Here's a chat to find out exactly how much your pump is capable of flowing under load, or rather what's the maximum amount of psi you can achieve with the jets that you're using.

This easiest way to test your unit it to do a volume test with a 5 gal bucket. For 60 seconds, trigger you wand in the bucket and them measure how much water is in it after 60 seconds, .5 gal, .7 gal, 1 gal, etc.

When you get that number you can then use it to reference what your pump is really capable of for a psi range, even if it's only 100 psi.

I understand what you're saying about just using the fresh water supply as your solution line, but personally I would never clean that way. You might dump or flow more water, however it won't really do any "work" or impact for you because it's not really under higher psi. It would be like throwing down your prespray, then just pouring a 5 gal bucket of water over it and extracting it back up. Yes, you're going to remove some soil, however not as much as you would if you had the impact of a high psi unit.

I don't quite understand your last question about suction.

Good answer Spot!

I always use a Koblenz or a 175 to agitate but like cleaning with more too. I have not tried cleaning with under 500 psi yet. I will try it soon and see what I think. If I was to clean with say 200 psi, I would try to get check valves/extenders to get the jets a little closer to the carpet since I think this would help with the "flushing" phase of cleaning.

Yeah, we're definitely getting into the personal preference category. I with you guys on the mechanical agitation, but it's hard for me to turn the PSI down now after coming from around 100 psi.

Just last night I cleaned the carpet in one of my janitorial accounts. I've cleaned the carpet before with about 100 psi, and I had to use a 175 and or my Rotovac just to get descent results.

However, last night I cleaned with 450 steady psi at the wand. I didn't even have to rake in the prespray or anything, and it came out better than last time. Not to mention, what took me 5 hours before, only took me 2 hours this time.

Do what works for you Phil. As long as you're happy that's all that matters.

You ain't seen nothing yet...

I just got back from ADCO Pro with my new Dema valve for my chemical injection. More fun to come.

I'm with you Phil, 95% of our work is property management and I like the idea of an electric unit. Since selling my Recoil (which I regret BTW) I am on the look out for a 1 machine that can do everything. I want heat, auto dump/fill, and good vacuum! I am demoing a few machines right now.............I will keep in touch!
