I purchased this machine for fathers day 2008 it was just introduced by karcher. I probably used the machine 4 to 6 times for light cleaning around the house. I purchased it through Northern Tool. Upon receiving it I noticed how difficult it was to thread the hose on not much room. Now the hose will not stay on. The pressure has blown off the plastic threads. Obviously a poor design. I contacted Karcher customer service which replied that the hose would have to be replaced. At my expense. I purchased the hose replacement through pressure parts .com and was surprised that the replacement hose has all brass internal fittings not plastic and a longer handle at the hose end to ease screwing into the machine. This is my second Karcher electric washer and last one I will ever purchase. It is a poorly designed machine. I thought a huge Corporation like Karcher would stand by there product. Obviously not
