What power washer do professionals use?

Professionals overwhelmingly run gas-powered pressure washers with Honda GX engines and triplex plunger pumps, typically in the 3,000–4,500 PSI range. Unlike the axial cam pumps in most consumer machines, triplex pumps run cooler and are engineered for daily, full-day use without premature wear, which matters enormously to a contractor whose income depends on the equipment starting every morning. Brands like Simpson, Mi-T-M, and Generac’s commercial-grade lines appear repeatedly across real job sites, less from brand loyalty and more because contractors have learned through experience which machines actually survive years of heavy use. For larger-scale work, belt-drive units that separate the engine from the pump further reduce wear. Electric units are essentially absent from professional fleets, since reliable outdoor power and extended runtime are rarely both available on a job site.
