Pressure washer

[autokomppania]

I was at this local diy garage washing our cars with my brother and as a result with clean cars, I decided to buy myself a new pressure washer. Right now I have an old Kärcher K4, with 430L/h output. I'm looking to buy a model with atleast 600L/h output and basically there are just two models, that are in my price range, Kärcher K7 and Kränzle 10/122. I gotta foam lance for the Kärcher, but it's only a 11€ adapter needed for the Kränzle to use my current lance, so that's not an issue.

What kind of pressure washers do you guys use to wash your cars etc.?

I stopped using mine (electric) because I was tired of listening to the damn thing every day.
