About Petrol Pressure Washers
Domestic petrol models start around 200 bar at 9 L/min; trade and agricultural units reach 250–300 bar with Honda GX-series engines. Expect 6.5–13 HP four-strokes with axial or triplex pumps.
UK favourites include the Hyundai HYW3100P, P1PE P3200PWT, SwitZer SZSW17 and Honda-powered Mac Allister units. Triplex pump models cost more but last 3–5× longer than axial-pump equivalents.
Best for builders, farmers, smallholders, contractors and anyone with significant patio or driveway acreage. Avoid using indoors due to exhaust fumes.
