7 Best Petrol Pressure Washers (UK 2026 Review)

Petrol Pressure Washer Review: Choosing the Right Power and Water Flow

A petrol pressure washer is useful when you have a large driveway, muddy equipment or outdoor areas far from a power socket. But choosing by PSI alone can be misleading. Water flow affects how quickly you rinse an area, a serviceable pump matters for frequent use, and a longer hose saves moving a heavy machine. This review compares seven petrol power washers available on Amazon UK, from a compact tank-fed model to high-output machines for demanding jobs.

What to Look For

  • Working pressure: Check rated pressure as well as the advertised maximum. Very powerful jets can damage pointing, wood and vehicle finishes, so start with an appropriate wider spray.
  • Water flow: Compare litres per minute as well as PSI. Higher flow can speed up rinsing, but your tap or tank must supply water at the required rate.
  • Pump and upkeep: Triplex pumps can be attractive for frequent demanding work; axial pumps often suit lighter duties. Check maintenance intervals, oil requirements and parts availability.
  • Hose and water supply: A longer pressure hose reduces repositioning. Tank suction and gravity feeding are model-specific, so check the setup and filtration instructions.
  • Outdoor safety: Petrol exhaust contains deadly carbon monoxide: never operate these washers indoors or in garages. Protect your eyes and feet, and never aim the jet at people or animals.
