I just received the power washer and the assembly was very simple. All that is needed is a single Phillips head screwdriver. The instructions are very well written. However, I found the assembly so simple, a little bit of mechanical intuition was all that was needed to complete the process. I haven’t tried to use it yet, I’m hoping the operation goes as well as the assembly.
I bought this the end of August and it has worked great. I had stains and dark areas on my concrete driveway that are now gone. I like the convenience of electric.
