I have the WPX2300E 2300 psi Westinghouse pressure washer It took me five days before I was able to take it out of the box and use it outside because of other commitments I had but I took it out put it together and put water on it and electric and everything. Just checked it out. Make sure it was working in spraying and then I used it to spray off the bottom half of the back of my house and it's concrete steps leading down to the basement door and it worked excellent. I ain't got no complaints.
