I bought the ETS when it was on sale, have had it since around November of 2016 and have around eight hours of run time on it. I note that any pressure and even without it, the pad spins minimally or not at all. If I turn the sander on its side, it doesn’t spin, even just fighting air.

Today, I pulled a new RO 125 from a box UPS dropped off and it spins like a champ.

Can anyone tell me if they have a different experience with the $99.00 special?

Mine is fine Kelly. I received mine at the end of January and probably have maybe 2-3 hours on it but seems to be good. Definitely use that warranty.

Love mine. It’s a finish sander so the pad has a very small orbit which works for me, a finish sander is what I wanted.

I have no problem with the 2mm orbit, it’s the spin I was wondering about. For example, do some units have to run a few hours to wear against the brake or whatever to up the spin factor?

The RO 125 has two modes:
1. Eccentric motion
2. Rotex or geared rotary motion
Could you be comparing the forced geared rotary motion of the Rotex 125 with the eccentric random motion of the ETS 125 ?

Mine turns very slowly, but does the job, very well. The main trouble with mine is, the cord keeps falling out, even with it locked in.

Thanks, but no.

I’m familiar with ROS finish sander-polish type units, since I have a couple. One is a variable speed Porter Cable ROS sander-polisher. The other is just a ROS. As you know, the spin motion can be stopped like the RO 125 in fine-polish mode. I also have variable speed grinders, so am familiar with the direct drive approach to removing material.

I expected the ETS to spin at least as well as my PC’s, since that is part of the technique to get to a scratch free finish.

I can set the ETS on a board and hold it by two fingers, at the cord (it’s that smooth) and the pad may or may not spin. The RO, on the other, wants to spin even if I stand on it (so to speak), even in polish-fine sand mode.

I never paid attention to the spin but I will​ look tomorrow. Are you dissatisfied with performance?

If the pad doesn’t spin, it’s just a round version of a 1/4 sheet sander, albeit with pretty good dust collection, which is good for the lungs and longer life sandpaper. As such, it would be less valuable than a 1/4 sheet sander for versatility, since it can’t get corners as well.

All that aside, go figure. I have a stack of garbage 3/8” ply a friend gave me for misc. use. Ran the ETS 125 to smooth a bunch for no good reason other than to give the sander more time to break in. Took a break, came back and the spin, finally, is going good. Even with 40 grit bogging it. I guess it did just need some run time.

Festool owners on the Festool forum mention other Festool sanders requiring break in time. Some just hang theirs and let them run for about six hours.

The hanging idea might be good, if you can do it in such a way that the pad spins, since it has to wear in, it seems.

Others mentioned the brushes breaking in. I’m not sure what that does, other than maybe a bit more power. If so, it should do really well, since the unit performs well, as far as power goes, right out of the box. Of course, you’re not supposed to use it like a sanding block. That is, you’re supposed to let the sander do the work, which requires a light touch (after working toward five decades, I still fight myself on that).

As to the question on satisfaction, I’ll report back when I take something down to finish level and clear coat it. As it sits, and if the thing doesn’t un-break-in, I’m [now] happy with the performance.

In another thread someone mentioned Festool sanders needing a break in period but since I’ve only owned one and it performs satisfactory I didn’t know what to think. Maybe mine was a test sample or something and got broken at the factory.

Kelly-
Glad its working out for you. I’ve read about the break-in period before but never put much credence in that position … I will file away your experience though. I was going to suggest calling Festool Tech Dept. but looks like you have it under control.
Good luck with your new greenie.

I have the $99 special (since November) and no problems. It seems to “random” more when I apply more down pressure, which seems counter intuitive, but it is what it is. Many hours on the unit.

Have your say...
