I use a pressure washer. It has 2 nizzles and the "rotary" high piwer one is far too piwerful. I rarely use it. By keeping the nozzles back the drop off in water power reduces the dangers. The nozzle also has a "choke" tip that can vary the pressure too. For "in between" washes I use anextended nozzle hosepipe attachment with swivel head and varying spray patters, mains water pressure only and easy to angle under the car.
I have never felt the need for highest pressure from the Karcher, but do soak the car/snow foam/ bug softener/tar remover before rinse/shampoo.. i won a handheld air blower in a Mogmag comp and that is great for blowing water off the car and out of crevices, a good tool.
