Can't speak about the Kondor or many other inverted Ls because I've seen very few. I bet there's currently less than 10 inverted Ls in in my metro area of one million people. I can say that in 2006 I removed two vectors and replaced with water wizard 2.0s and the customer response was hugely positive, despite concerns of kinda going backwards in design and aesthetics and having to install guiderails to force customers to drive in straight. If customers have gotten a bad taste in their mouth from previous negligent owners it might help to install something new, but you can do a heck of a facelift on most machines for 10K. If you clean and wrap the old automatic and cashier and install extrutech and some aftermarket LED lighting it would look like a new machine. As with all touch frees, effective chemistry is hugely important. Find a local distributor that knows how to clean in you immediate geographical area. What works there in
touchless cleaning might not work as well even 100 miles away.
Post pictures of the place and the machine to this thread. We love to spend others people's money!
