I can't answer the question as asked
I won't use an RX in a residential, to slow and bulky and you need a different tool to get to the edges
I don't use either tool without a
glide on it or without high flow
drier is cleaner, generally the water you leave behind in a carpet is gonna be close to the color in the waste tank but if you use high flow with great recovery then the equation can change
Glided RX 20 seems to leave the carpet wetter then a Ti wand in the residential setting but doing an olefin cut pile in a restuarant the glided RX 20 was much drier, hybrid glide on the wand and hole glides on the RX
but when you put that RX 20 on the heat of a
vortex then you may get a steam bath in close quarters
I would suggest you talk to Walt Bush, he could probably answer a lot of your questions
you really have more things to compare
