Good article on CFM, Waterlift.

You can get one or the other, but NOT BOTH at the same time.

Add it.. I did on my Recoil.. Faster dry times..

Thanks Friendly.  I think I'm going to go ahead and turn my machine into parallel vacs.  I'm also going to make the intake on the recovery tank 2" instead of 1.5.  Shouldn't be too hard.  Of course I would then need to run 2" hose.

Yesterday I did a job using 15 feet of hose, and it dried faster than any job I've done recently.  It was actually easier to work with 15 feet of hose than 25 feet for the most part as well.

The only reason I use 50 feet sometimes is so I don't have to carry the machine upstairs on a two story house.  Now I plan on getting a continuous piece of 50 feet 2" hose and running the machine in parallel.   And for one story units, I'll stick with the 1.5 inch 15 foot house.  Would 2" on such a short hose even matter?

I was told that vacs in a series would be better with low pile, commercial type carpet.  I would think that would be because the seal is pretty good at the wand, so lift would come more into play. Vacs in parallel would better suite thicker, residential carpet, due to the seal not being as tight, thus airflow being better. Does that sound about right?

Perhaps, but if you've ever seen that carpet, I would think you would wonder what the difference is. That pile is so thin that "pile" is almost an oxymoron. Sure the seal is strong, but how much water can you get in 1/8 of an inch of carpet?
