I recieved the Ss Brewtech keg washer recently and yesterday set it up and cleaned 4 kegs.
Setup was a snap, and since the unit attaches to the inside of the keg it worked equally as well with my single strap handle kegs as it did with the rubber top kegs. Which is something that the other keg washers won't do, if you have single strap handle kegs you're out of luck.
I set up 3 buckets with 2 gallons of water in each, one with hot PBW, one with warm rinse water, and one with ambient Sani Clean sanitizer. Run a cycle in each and just move it down the line. Couldn't be easier, worked like a dream, no monitoring necessary - just a timer for each cycle.
It's a well built unit that will last a long time, and for me, it is worth the money I spent on it.
