Rated 1.0 out of 5.0 by Didn't Even Last Through One Deck Washing! This Karcher pressure washer was received as a gift. Used this washer for about 6 hrs over one week period. At first, it worked well, and except for awkward hose and cord connector angles on the unit(two hoses and power cord all go out in opposite directions), it did the job as I expected. However, yesterday, the unit would not turn on, and the GFCI will not test/reset, which means the motor will not run. Checked all outlets and circuit breakers at the source; no problems there. Called local Karcher dealer, who said they don't repair. Called a local electric shop, who would repair by replacing the GFCI (made in Honduras), but who did not recommend that because the cost of repair labor plus parts from Karcher would exceed the price of a new unit (Unit is out of warranty). Luckily, this was a gift, but it's a piece of junk, Made in China. No way I would ever buy a Karcher pressure washer!! August 29, 2014
Rated 2.0 out of 5.0 by Lasted Only 2 Seasons This is the second one I've gone through. It's fairly easy to handle & light weight - the price also had appeal. After the first one died I thought it was a fluke, wrong! Evidentally, it only has a 2 year life span (have seen this written by others as well). Didn't use it for any big time jobs so figure it's not worth it. Bought another brand for a little more cash - better to have one when you need it. April 1, 2013
Rated 1.0 out of 5.0 by Karcher 3.46 Not recommended I bought mine in May 2010. I did well according to the review. Mine worked right up till last summer when in August it would turn on but not pump. This was after less than ten uses. Stored in my heated garage over the winter, and well out of warranty I pulled it apart and found the pressure switch seized. All components marked made in China. A very nice guy from Karcher Customer service offered me the part I needed for only $86. The unit cost me $169.00 new so will cut my loss and not buy another Karcher. May 14, 2014
Rated 1.0 out of 5.0 by LOUSY PRODUCT AND MFG. COMPANY! Great if you only need it for one job. Didnt make it through one season and no one standing behind the product, not the store or the manufacturer! BUY ANOTHER BRAND EVEN IF IT COSTS MORE October 7, 2013
Rated 1.0 out of 5.0 by unusable since I got it Don't know have been waiting for almost 2 months to get a replacement trigger for a faulty one, when I recieved the unit. So haven't gotten to use it yet. April 10, 2012
Rated 2.0 out of 5.0 by Frustrating the hose keeps disconnecting Whenever I move the machine the hose disconnects from the machine. The yellow adapter that is attached to the hose does not stay attached to the machine. Should be designed better than that. June 11, 2013
Rated 5.0 out of 5.0 by This product is easy to use This pressure washer did a great job in cleaning my patio and sidewalks and worked exactly as described. It is well made and although I've only used it once so far, I expect to get many years of use. I trust the Karcher brand, mainly because a friend has a Karcher Pressure washer and after 5 years, it's still going strong! July 10, 2012
Rated 4.0 out of 5.0 by Used over 6 yrs I bought one in like 2006, it was rated 1750, it works good but slow if the concrete is heavy mildewed or dirty, but after that if you clean once a year its fairly quick. I ran it for 8 hours straight many times. This year the wand started leaking where it connects to the trigger, still works good otherwise but a new wand is 40 bucks, yikes! I'd go with a 2000 psi if I get another. If you want to do a lot of cleaning get a gas powered one. The electric is good for home use. February 28, 2014
