I have two classics, a big guy and a hammerhead 20". All with two nozzels. I am looking to get rid of my classic's and the big guy but I am torn what to get next. I run 8gpm on 3 machines 2 hot and 1 cold. I will also be running one 12gpm cold on a reclaim.
I use steel eagles 27inch vaccuum surface cleaners i have one machine that 7gal per min at 3500 and 5000 psi at 6.5 gal per min they are heavy about 65lbs but they are great we can do about 9000 sqft per hour they recover well to.
I am not sure if the angle of the nozzle from the vertical on Steel Eagles is greater than the mosmatics or if the swivel just has the least resistance to rotation of any SC out there. Not sure but they sound fast, as fast as landa's water jet.
