Ain't nothing Mystic about that piece of equipment. Lets break it down.
#1... 3 to 3.5 gpm is not effective for running a 24" to 30" surface cleaner.
#2... No Hot Water....Nuff Said
#3... Whats that cost $3-$4,000 bucks??? For that money you can buy a 8 gpm cold machine and a Big Guy, and be able to dance circles around that thing.
I'm sure it may have it's uses, but it's nothing I would consider buying.
