Brand is All-Power, 1800 PsI , still in the box it came in, has not been opened. Shortly after it arrived I had 2 heart attacks close together. all the outside work I used to do myself I can no longer do. I ordered it in 2011 and never got to open it. potential intrested buyers may open it to see if it is still ok to use. call me at # click for number, come by my home at 2121 shipley rd, there is a handicap ramp in front of my house.
