The RO 150 is far more powerful.
If we look at the numbers the RO 150 is a 720 watt sander, the Deros 500 watt. That's 31% more current the Ro150 sander could draw over the Deros. Even tech larger sanding stroke of 8 verse 5 just cant make up for raw power advantage.
If I thought the Deros removed the stock as fast as the RO 150 I would not have returned it. In side by side tests the RO is faster in my shop. Actually, the Deros was only marginally faster than the Festool EC and not enough to make me keep it and the Festool EC is only a 400 watt sander.
I never tested the 8 stroke because I dont want additional sanding it would require for me. I am not even sure if I could get that 8 stroke, I never looked in to it. I find it hard to believe the 8 stroke could overcome 30% more power in any sanding mode though.
Both in starndard mode?
Everyone I have heard on the subject says that the RO
"when not doing geared" is slower, and that a lot of the power drives the head.
In geared mode of course it it faster. Maybe not as good as a RAS.
Are we comparing apples and apples (In non-geared mode)?
Also I thought the DEROS is 450W, not 500W.
( in 110v land, of if one is adverse to a paddle switch, the ETS/EC is pretty much the same as the DEROS)
I have the 5650 unless the motor is working the extra watts are no advantage. I have to really push into it to get the full watts. (And I do not)
The RO is 3600-6000 rpm, the DEROS is 4000-10000. (Advantage DEROS)
The bigger the stroke the better for removal, and I assume both were 5-mm?
As I do not have the sanders to compare, these are somewhat questions.
