Thread: Mytee Speedster Motors

I want to upgrade the motors on a Speedster 1000-DX200 sold with a 360 Rotovac.

There is a tag on the motors (116472-13) stats: Waterlift 106.7", CFM 112, AirWatts 404, Amps 10.7.
What is bothering me is the 2 motors that came with this system are rated at 10+ amps each. I can run this from a 15 amp circuit with a pump and I dont pop any circuits.

I got 2 new motors (116765-13) Stats: Waterlift - 136", CFM - 95, AirWatts - 465, Amps - 13.1 I was going to go with a 2 plug system. I now wonder if I can just use a 20 amp circuit with the 1 cord?

What is going on with the markings on these motors? How can I run 2 motors rated over 10+ amps and a pump on one 15 amp line?

They rate the amp draw of most vac motors in FREE spin. When there is no load on the motor at all, not even the minor restriction of air going through an empty waste tank.

Now, when most motors are installed into an extractor they usually drop an amp. When the machine is in use, like carpet cleaning, there's an even further restriction when the wand is locked to the carpet. It's the sound that you hear when the motors start to labor. They actually spin up, but because there's less air going through the system the motor doesn't have to work as hard.

So, it's not uncommon for you to drop as much as 2 amps or more per motor when you're actually using the machine. That's why you can run your machine like that.

I would venture to guess that you're very close to your 15 amp threshold with your current set up. You have a fairly small pump that should only draw about 1 amp during use. The rest is left over for the vac motors, but I'm sure you're very close.

You might be able to get away with the new motors running on a single 20 amp circuit, but personally I would split the motors into their own cord. I ran a machine just like yours when I first started. Even though most homes have a 20 amp service, I would often blow a 15 amp breaker because someone would have a small appliance hooked up somewhere. What happens when your on a job with the new motors and you keep blowing a breaker that you thought was a 20 amp circuit? You're not going to be able to find a 30 amp somewhere...

I did what you wanted with the bigger motors but added another cord, and no more blown breakers.

You might also invest in a small amp meter. They can be very handy when you start modding your equipment. If you do that, you can rest assured that your new upgrades won't start causing you new problems.

Good luck

No problem, let us know how it turns out.

Well, I can tell you from experience that even 40" of more water lift is huge when it comes to dry times with these Speedsters. As mentioned, I started out with the exact 1000DX-200 like you have. Even with extra dry strokes I really struggled to get dry times where I wanted them to be.

When I started modding my machine the vac motors where the first thing on my list. I opted for the C302A motors that Mytee puts in their M-5. Those motors are rated at 115 cfm and 148" of water lift. When I did this upgrade it was like night and day.

As I'm sure you know Mytee puts their motors in air parallel. It's ideal for longer hose runs, but if you have low lift motors like you have your dry times will suffer. I'm really starting to think lift is king with these porties, but that's another debate.

If you already have the new motors, why not give them a shot. It's a fairly easy mod in my opinion, but to each their own.

Hey Greg,

I would love to see how your upgrade turned out.

Here's some before and after pics of my project, I'd be curious to see if you did things similar.

Now I know the photos aren't the best, but you can do a pretty big vac and pump upgrade in these Speedsters.

I used Mytee's C302A 3 stage vac motors, and a custom pumptec pump.

If I really wanted to upgrade the right way I would pull every thing out and start over,
I dont have the tools or the inventory of parts,

Well it looks like you did a pretty good job with what you had. I see what you're talking about with the hose cuff going to the intake stack. I ran in to a similar problem, but I modified the manifold that the vac motors sit on and turned each motor counter clockwise about an inch. That made the exhaust transition straighter and didn't create the kink that I had when I first started. However, reworking the vac manifold also slid the motors over just enough to prevent the stack hose cuff from hitting the motors.

Greg, did you use any silicon for your hose connections? I found that increased my total vac lift because I have little to no blow by now.

I have a much older Speedster wherein there are two (2) intake pipes so my up0grade will be easier.

I assume Mytee made the switch to increase airflow since it goes 2" all the way. (?)

I still only have the 100 PSI pump but with 2X 11003 Jets that is enough.

I had considered losing the pump altogether and re plumbing the thing to simply accept water from the hose bib or faucet and whatever pressure that gives. However, I do not have auto dump...

Hey Phil,

Can you post some pics of your dual stack set up? Thanks

I can and gladly will. Gimme a few day.

suddenly it occurs to me that auto dump may not be that vital IF the unit is set next to the head... all one need to is pull the plug now and again...

To upgrade my unit, one needs longer brackets/screws for mounting the 3 stage motors. I had already split the cord so one vac/pump are on one and the othe vac is the other. Plus I have the Mytee 220 conversion kit(s).

I am selling my TM to go back to the porty setup. Higher profit margin by far.

Hey Phil,

It sounds like your ready the give the other TM guys some hell, lol. Good for you.

As far as auto fill and dump, that's the next thing on my list. Because of my pump upgrade I go through buckets like crazy. Sure, I can just turn down the PSI, but it's way too much fun to clean with TM flow and steady PSI.

To answer you question about the mounting brackets, Yes you need to get the longer rods that the screws go into. If you're in a pinch you can also just use some longer bolts and use your old rods. However, you would need to be very careful not to over torque you bolts and collapse one of your fan chambers on the vac motor itself.

I also did not use any silicone and have 0 air flow when I have the hose plugged.

I really dont like the 12 gal tanks on the speedster, too small and with the ball float its only 8 gals before the problem happen. Its also a tall unit and is about the same level with some bathroom facets. Being so tall you cant use gravity to fill the solution tank.
I want 16 or 20 gal tanks and the motors mounted on the out side of the unit.
I think I want a shell of the Recoil so I can build a system I want, but dont have the time right now

The Recoil shell might not be a bad way to go, however why not just add auto fill and dump to your Speedster like you were saying? I'll be adding that stuff to my machine as well but it will all be internal. Plus, the auto fill that I'll be using has a chemical injection system in it too.

I was not planing to add auto fill / dump. I have manual tools.
A pond pump is able to take in sand and some large debris. I have a large 250 gal per hour rated pump $105 from a garden shop.
I will dump in a kitchen sink

edited: The pump has a per filter for hair and tiny rocks.
