Karcher K5.85M, I have two both Gen 1 and Gen 2. They are the greatest pressure I have ever used, keep mind I also have a kranzle Quardo 599. Any questions man, you have my number, I`ll be more than happy to send you a video in action.
Note, they are VERY hard to find but worth their weight in GOLD. I bought my second one as a back up from a German tool enthusiast who is a quality freak like me. You won`t find a better built PW for the price, the plastics are insane, hoses & power cords use the quality rubber that lies on the ground and doesn`t whip up and hit cars.
