What do professionals use for pressure washing?

Professional pressure washing setups typically pair a gas-powered machine, usually in the 3,000–4,500 PSI range with a Honda GX engine and triplex pump, with a dual-lance or quick-connect gun that allows fast switching between rinsing and detergent application. Many professionals also use a surface cleaner attachment for flat concrete, since it distributes pressure evenly and finishes large areas significantly faster than a handheld wand alone. For siding and roofs, professionals switch to soft-washing equipment entirely, using a low-pressure pump sprayer or a dedicated soft-wash injector system rather than the high-pressure gun used for concrete. Extension wands are common for second-story work, avoiding the need for ladders. The combination of the right attachment for each surface, not just raw pressure, is what actually separates professional results from a typical DIY attempt.
