I am in the market for a low end commercial pressure washer with either 3.5 GPM or 4 GPM water output at between either 3,800 PSI to 4,400PSI, somewhere in that range. I have started doing some side job pressure washing and need something a little more than what I have. Do any of you pressure wash or have a pressure washer similar to this? Do you like it or dislike it? Pros and cons please. What kind would you suggest or what kind would you steer clear from?
