Westinghouse ePX3500 Showdown: Tested Power For Homes… Versus Price! We were eager to test the Westinghouse ePX3500’s performance, especially given its 2500 Max PSI and 1.76 Max GPM. The anti-tipping technology proved reassuring as we tackled caked-on grime on driveways and lawn furniture. The onboard soap tank added convenience, and the 5-nozzle set allowed us to switch effortlessly between gentle washes for patios and more forceful sprays for fences. The pro-style steel wand felt sturdy, though we wished the handle were more padded. While our tests showed solid cleaning power, we balanced it against the price point. Is the ePX3500 a worthwhile investment for occasional use? For us, it delivered reliable results, but we’ll hold off on a full endorsement until we see how it holds up to heavy-duty tasks.
