Powerful, appears to be built to last

8 days ago
Went to commercial grade 4000PSI after having many cheaper less powerful home units fail on me in various ways. This was clearly a much better product and build quality. Can tell it’s built to last!

This power washer is very easy to use. I was able to overcome the learning curve quickly and become very comfortable using it on all surfaces within a few hours.
