Westinghouse ePX3500 Showdown: Max PSI Power vs. Anti-Tip Ease… Car Brands Maximized! We were intrigued by the Westinghouse ePX3500’s dual strengths: its 2500 Max PSI and 1.76 Max GPM delivers robust cleaning for cars, fences, and driveways, while its Anti-Tipping Technology ensures stability during heavy use. The onboard soap tank simplifies detailing jobs, and the pro-style steel wand, paired with the versatile 5-nozzle set, caters to various surfaces. Our testing confirmed its reliability on tough grime without sacrificing maneuverability. Though it’s powerful, we noted its size is best suited for medium to large projects. The inclusion of durable components, like the steel wand, reflects its build quality. For us, the ePX3500 strikes a great balance between raw power and user safety, making it a standout choice for tackling demanding cleaning tasks with ease.
