Which pressure washer do professionals use?

Professional contractors overwhelmingly favor gas-powered machines with Honda GX engines and triplex plunger pumps, typically operating in the 3,000–4,500 PSI range. Unlike consumer-grade axial cam pumps, triplex pumps run cooler and are built to handle eight-plus hours of continuous daily use, making them dramatically more durable for full-time work. Brands like Simpson, Mi-T-M, and Generac’s commercial lines show up repeatedly on job sites, chosen less for brand loyalty and more from years of contractors learning which machines survive daily abuse. For larger commercial and industrial jobs, belt-drive units that separate the engine from the pump reduce vibration and heat, extending equipment life even further. Electric machines rarely appear on professional job sites, since outdoor power access is unreliable and commercial jobs demand hours of nonstop, high-output run time.
