Kyle, the only problem is, that if you use those things a lot- or at all, they will burn up after a while. Just search the old posts on pressure washers. I have gone through 4 Karchers in less than 2 years.
We just got a 2500psi gas washer and used it ALL day today to clean and reclaim about 25 screens- dont ask me why they took all day, but.....
The electric ones are good to start out with, but you get tired of buying new ones.
I've been using a 2500 gas washer too. My only concern is what is it doing to the tension of the mesh? I don't have a meter to check screen tension.
Have you checked tension after using the 2500 psi washers?
I still plan on using the gas washer.
