Wish I could go into depth on this issue, but will surfice to say:
Gentlemen;
Both systems will a certain job, I'm sure. And, some systems are better than others. Compare all spec's carefully.
It seems to me that we dry carpets by using "AIR" flow (movement) --perhaps in terms of using box fans, etc...to help get carpet clean and dry.
Furthermore, if a system is capable of going the distance, that may tell one something as to the total over-all performance.
Finally, I believe that Mark Roberts will experience the need for greater Air-Flow on his system based on the fact that he has purchased a unit to help provide that. (BTW, it is not our system, Gentlemen)
Hope my comments did not sound like a sales thread because they were not meant to be.
Good Fortune to all;
