I have never tip bloomed a carpet (that didn't deserve it) with OP,
Well Grant when you think of a nice new 175 running you about $800, and tons of pad choices that go with it, makes you wonder. But I still can't imagine a 175 out cleaning me and my mighty defender, let alone you and your trinity monster, beast cleaning unit.
I got an old 20 incher sitting in the shed, it's to ugly to use, maybe next empty I will try it out and see how it works compared to the OP. Last time I used it, I got rag dolled all over the living room.
