Sorry for the delay guys.
I ended up purchasing my Flex 5, five brush system this summer. My local distributor did an incredible job tearing out my old system and putting in the new machine. My thoughts on it - it is a great machine. I have four wash packages, cheapest/fastest being their new "express" solution. 2 Passes. First Pass is
Soap in the front end, brushes, and wax & water on the back end. Yes all happening at the same time. The Second Pass is the dryer back to home position. Total Express wash time is 3:5 minutes. Definitely a lighter wash, but gets the job done for the locals looking for a quick wash.
My Ultimate wash (top wash) is six passes, total time is 5.5 minutes. Still pretty fast for a top wash.
So far it has been a good system, but as it is a new machine/system there have been a few bugs that have been (and still need to be) worked out. The support is great, and they are working on the items I have expressed concern about. I went to Bristol, VA for a few days and dove into the course they offered. Sharp engineers, and very much available when you need them.
I'll try to share some pictures sometime soon. Overall good machine so far - will keep you posted. Shoot over any questions if you have them.
