My Karcher has been great (going on I think five years now) operationally.

One thing to watch is the interchangeable nozzles like to not fully seat. Normally you push them in and give them a 1/4 turn to seat them, but I've noticed they often don't fully seat and are not actually locked into position, even though they might look it. I found this out the hard way a couple of years ago when I aimed the nozzle at my Benz and squeezed it on. Fking thing launched the nozzle right out of the hand piece and right into the sidemarker light, shattering it. $120 to replace. Grr.

At the very least, each and every time you replace the nozzle, aim it in a safe direction and spray just to ensure it's properly seated. Live and learn. Other than that however, it's been great.
