Rated 5.0 out of 5 by 1 reviewer.
Rated 5.0 out of 5.0 by Excellent Pressure Washer I have always purchased the high-end consumer 2800 to 3000 PSI Washers for about $500 and did not see the need for a larger unit, but I have a lot of concrete and a large fence that I wash every year. The standard units blew up about every 3 years so I just threw it out and bought another one, still cheaper than paying someone else. I finally decided to purchase this pressure washer (a real one) and I am very happy I did, jobs take 1/2 the time and the cleanup is a much better job, well worth the price. But your arms will be sore from using this machine because it is so powerful, but a lot of fun to use. I think I sold 3 more of them while I was using it; all my neighbors were coming over and asking where I purchased it. May 29, 2010
