For Very light duty work!
When new, (Aug '08) the washer worked great, not extreme pressure as needed for some jobs. but great to wash the car and general light duty cleaning. It is a light duty machine and if your intending to use it daily or even weekly you'd better invest a couple of hundred more. Mine is 1 year old with major issues, plastic elbow in the machine started leaking and needed a new one ($31.00 w shipping)and now a month later, the main hose blew, did have a kink in it though, but I take care of my tools so this would not be uncommon for the typical home owner. Should have got the clue when the FIRST one I purchased from [...] didn't work when I got it home!! I would consider this purchase was like throwing the money away since my previous washer is over 20 tears old and has never had any issues but its heavy and bulky. The new hose is $50 and considering I already spent $30 I'd be better off spending that $ toward a new heavy duty type machine. I should have bought something more durable even for my light duty projects. In this case, you get what you pay for!!Oh, on the plus side the circular wand attachment IS a great cleaner!

Don't buy this product.
Read other comments. The gun begins leaking after a year and renders the whole unit useless. Karcher won't stand behind it. [...] can't fix even if you wanted to. Karcher gets your money. You get pile of garbage.

Very Unhappy
In the past three years I have purchased two power washers. One broke the second year and the other broke the year after that. Both are out of warranty. I am not pleased. I am out over [$]and have no power washer. I wish they made a better product.

Highly recommend this pressure washer
I have used another Karcher pressure washer and had only two complaints. The supply hose was hard to connect and disconnect and the storage for tools was inadequate. I was impressed that both of these were improved on this model. A company that strives to improve their products gets my patronage. I like everything about this purchase.

It's the best one I've found.
This is the second one I've had. The first lasted 12 years and never gave me a moments trouble. When it finally died, I knew that I had to have another one. Simple and easy to use, idiot proof and does a fantastic job. I'll buy another 12 years from now.
