Hi Tony,
Instead of a question for you I have a compliment!
I was just cleaning my own carpet and it reminded me, I have only had to use 50 feet of 2” hose so far on the jobs I’ve done, and I have to tell you that the vacuum on my 115 is pretty awesome. I’ve never used a truckmount so I can’t compare in that regard, but what I do know is that the wand (from Wanders with slotted glide) sucks down so hard to the carpet that in all honesty I think 100 ft of hose would probably be about Right!
I definitely was concerned about the drying aspect with a portable, and always read about that as the typical knock on them but that is DEFINITELY not an issue! Of course, there’s a portable and there’s a PORTABLE.
The customers that I have cleaned for are stoked with the dry time. I do have a theory that a lot of truckmount guys use pressure as a perceived short cut around using more agitation and proper chemistry and end up drowning the carpet and working against themselves in reality. To me 350-400 psi is plenty on typical carpet and the results have been great.
Anyway, hope I made your day a little.
