Rated 4.3 out of 5 by 8 reviewers.
Rated 5 out of 5 by Attention! One very important thing, this product only can use highest fuel type. It is 93 in my NC. I use 87 fuel type, it won't start and can cause starting problem, please never use cheap gas. Powerful machine. Pump is made in Italy, engine by Honda. It is easy to install. It need 1 quart of enclosed oil for the engine. Pump got its oil ready. I recommend this pressure washer to a friend. September 11, 2014
Rated 5 out of 5 by Simpson Powershot A great addition to my maintenance tools. Easy to assemble and started smoothly. Very powerful with the addition of a rotating nozzle..The o nly thing bad is the hoses and wand are tacky and cheap. I use 3 other washers and all hook up universally. The Simpson hoses do not and are cannot handle heat. Buy a quality wand,turbo nozzle and hose and you will own a very efficient piece of equipment. May 20, 2014
Rated 5 out of 5 by best buy the hancle was difficult to align. the pressure washer met all expectations. July 20, 2014
Rated 5 out of 5 by Simpson Pressure Washer I'm very satisfied with the Simpson pressure washer as it works great, easy to start and is a well built unit. Simple to set up out of the box and works as advertised. I picked the unit up at my local Home Depot after ordering the pressure washer online with no problems. May 13, 2014
