I bought this in July and have not had time to open it and see what I got for my $100 during that big sale. It was 50% off. I live at the beach and have colored concrete around both sides of my home and during these last two years and all the rain here in Cali on the Central Coast I ended up with mold in the concrete and on my retaining walls. The concrete mold would NOT wash off so I thought, what the heck I am going to try a power washer and do it myself before forking out money to have my concrete recolored. Mold on concrete can be dangerous to your health and can cause allergic reactions, respiratory problems, and lung infections. Mold can appear in different colors, such as black, green, white, or brown, and can have a fuzzy, slimy, or powdery texture so it must be treated. I opened the box and the instructions were very easy to follow. I put on the wheels, struggled a little putting on the handle because it didn't fit great, so don't force it, just keep trying and once you get it in, it will click and be fine. The nozzles store easily on the unit. I did have an issue with the way the water hose attaches. The first piece you screw/twist on goes one direction and when you screw on the hose it goes the other direction, so a couple of times it would leak where the water hose attaches. I had to move it from one side of the house to the other so the second time I attached the water hose I was sure it was secure. It still leaked water but not as much and it didn't take any pressure away. I was barefoot and three times I ran that pressure spray over my foot and wow, that hurts. Don't make the mistake of plugging it into an outside plug outlet where it cannot lay it completely flat. My outlets have that plastic cover with a latch at the bottom so getting the plug to lay flat could not happen. I did this because I was rushing and it didn't occur to me it needed to be secure and flat. I could never get the machine to come on (motor sound) when I pressed to foot pedal, not thinking about the connection. It would still spray water in a trickle but no motor would come on. I moved the plug to my garage where it could be completely flat and it worked fine. The long cord was really nice to have so you can move around easily. The one thing I disliked was when I pulled or pushed the unit to move forward, it was difficult at times because the hose screws in on the side of the unit and hose curves because you have the hose in the front of the unit when you are working so when you pull it, its turns sideways. It was a minor issue. The pressure power was great. I used water only without any soap and was able to spray my vinyl fence down to clear all the spider webs and dirt. I cleaned my house walls which are stucco and my downstairs windows. I mostly concentrated on my colored concrete walkways. I used the large strongest nozzle and made small circles on the mold stains that were deep in the concrete. You can see in the pictures what looks like drops of paint that are Brown. And on the retaining wall it is just Green. I really thought I was going to have to pay to have my cement ground down and repainted. After a few hours I was finished and it looks brand new. I turned off the hose and sprayed out the remaining water. I unplugged the unit. Removed the hose from the wand and the unit and drained that water from the hose and put it away! I plan on taking it to my upper two decks to spray the ceiling of each deck next. I would recommend this unit. "I'm just a girl ~ one happy girl"
