I bought the WPX3800 as an upgrade from my previous pressure washer, specifically because I wanted higher water flow. Going from 2.4 to 3.6 gallons per minute doesn't sound dramatic on paper, but it's a 50 percent jump, and you feel it immediately in how fast surfaces rinse clean.
I've put it through three different jobs so far: soft washing the house exterior, cleaning a wooden deck, and power washing concrete. It handled all three well, which is really the selling point, since most machines are good at one end of that range but not both.
Setup out of the box was incredibly easy. I had everything put together in less than 15 minutes, and it started on the first or second pull every time. Minor gripe: The instructions for the soap hose and thermal relief valve were unclear.
If you're stepping up from a lower-GPM unit, the difference is real. Recommended.
I bought this a year ago. It has been a good pressure washer so far. I have had a bit of an issue recently with what I believe to be the unloader valve. Hopefully I can get this fixed.
I'm just disappointed that a few bolts were lying around, but overall, a good choice. The pressure is fine and good and okay, and I'm still expecting good things from this.
It went bad in 7 months. I contacted Westinghouse. I am sure they will take care of me and I will come back to update this review with the outcome.
I would recommend this to a friend!

This power washer works well, but is extremely hard to start with the claim of “easy start”. The power washer will only start with wand not connected to hose.
