Mr. Clean Car Wash System?

I love mine! The only downside is its kinda expensive in the long run because you have to use their soap and you have to use the filters, and you have to replace the filters frequently. The filters are like 7 bucks for a 10x uses. I am glad I have one though because they do save a lot of time, and no water spots is always a plus, I HATE water spots.
 
I actually have a water pump in the backyard push underground unfiltered water to my garden hose and the Mr. Clean seemed to really help with my water spot issues due to hard NC water. Anyone else wonder how much of that rinse soap really gets washed off by the filtered water? Mine seems to come out like a mist.. eventually it gets most of the soap I suppose...
 
On two cars, the first car (black):
It worked for me on the third time, the first time, it left water streaks and it really made my car dirty for some reason, the second time had more success, but water still beaded up, the third time it worked good, but it had a few water spots..

On the second car (redfire), it worked perfect, no water spots at all.
