I purchased our Karcher powerwasher and was initially very pleased. It worked great! But after four or five uses, the motor quit working. Each time I used it, we had to coax it along because the powerwasher kept tripping our GFI outlets. We called the 1-800 number provided and were referred to a repair location that no longer works on Karchers. Too bad this product has so many problems...
