For what its worth I have had 4 Karcher power washers. I like the design and how they function but they are not reliable. It's interesting that they have a decal on the side of the unit promoting their "No Hassle Exchange Program" What company do you know advertises the fact that they have a special plan to exchange a product. It's like they know their products are going to fail and they do.
After my first purchase and exchange I gave up and bought a new unit. After a year it failed and they sent out another unit. It arrived and would not work properly! Now they are sending a second exchange unit. Great service but the fact of the matter is their products just don't stand up.
When I called the company to register my concern they were really not interested and basically said well that's your opinion.
