John, I am NOT trying to be confrontational, however I am a stickler for facts.
OP not only does a better job...
It does it faster..
Now, that is not opinion, emotion or any such thing, that is simple physics. Yes I know what the chemistry does, however we have proven that just because the chemistry is there, does NOT mean all ways of applying it are equal. To do the SAME job as a OP you are required to operate the rotary n, s, e, w and then diagonally, OP does that in ONE PASS.
We have found since building the Trinity that regular OP machines can NOT deliver the same results, they can do a good job however they do not do it nearly as effectively nor do they clean nearly as quickly.
Everyone likes to enter emotion and opinion, and that is cool, but when it flys in the face of simply physics, then it because more of a hype then a statement of fact.
