Nice Upgrade for Me
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.
