This pressure worked great for both our patio and our siding. There are a couple of challenges with the design you should be aware of. The soap dispenser is challenging to fill. Also you can't select whether or not to use the soap, except by no filling the soap dispenser. If it's in the dispenser you're using it. Last thing, the cord wrap and nozzle holders on the sides slide up into the machine, so when you push thing down into them they tend to pop off. We had to glue ours in. Beyond those challenges, I love it. It's easy to use, rolls along smoothly, isn't too heavy and cleans well.
This pressure washer works as advertised and we surprisingly easy to assemble. I used it to clean my tractor and spray off the car. So far no complaints.
I bought this electric power sprayer late last month and I was a bit skeptical since I've only used gas powered models before. I was pleasantly surprised at the power this unit has. It removed the dirt as easily as a gas powered sprayer, but with a lot less noise and much easier setup. I really like this sprayer. I would highly recommend it to others.
