About Heavy Duty Pressure Washers
Hallmarks: petrol or 3-phase electric motors, triplex plunger pumps, steel frames with full roll bars, and 250+ bar pressure. Tank-mounted accessories like surface cleaners and turbo nozzles are standard.
Top heavy-duty picks include the Hyundai HYW3100P (petrol), Kärcher HD 9/20-4 M (3-phase), Comet KS 1900 Pro and Nilfisk MC 5M. Trailer hot-water units add diesel burners for grease work.
Expect £700–£8,000+ depending on power source and burner. Worth the investment if your washer earns its keep daily.
