How many PSI is a good pressure washer?

For most residential needs, 1,700–3,400 PSI covers the full range of home tasks. Light jobs — cars, patio furniture, screens — call for 1,200–1,900 PSI. Mid-range tasks like decks, fences, and siding fall in the 1,500–2,500 PSI range. Driveways and concrete, the toughest residential job, typically need 2,000–3,000 PSI, with 2,500 PSI widely considered the sweet spot for cutting through oil stains and mildew without risking damage. Anything below 1,500 PSI struggles against real buildup; anything above 3,400 PSI starts entering commercial territory better suited to professionals. The “good” PSI isn’t a fixed number — it’s whichever range matches your hardest regular cleaning job, since buying more power than you need just adds cost, weight, and risk.
