Purchased mine to powerwash my driveway. I love the build quality, you can tell it in the actually nice screws and bolts that you are given to put the power washer together with. I do find that the 2300 is a little underpowered for what I want to do with it, but that is not a nock on the powerwasher that is me not wanting to spend for the higher PSI model. Overall would def recommend, and if you are on a budget this will clean concrete, just it takes a little longer.
I've only used it a couple of times, but I like it so far. This is my first time using a pressure washer, so I wasn't sure what to expect. I cleaned my concrete and my house. Our water is really hard, so the house didn't get as clean as I wanted with the soap application. But I may need to go over it a couple of times.
I love this pressure washer, it is easy to use and light enough for me to lift and place in my car! It gets the job done and I have had no problems with it.
