Best High Pressure Washer Australia
Australian driveways, patios, and cars take a beating from red dust, bird droppings, and UV-baked grime that a garden hose barely touches. A pressure washer delivers 50–80x the water pressure of a standard tap, cutting cleaning time dramatically. We cover both electric models for suburban use and petrol units for larger properties and rural jobs.
Buying Guide: What to Look For
- 1Check your water supply pressure first — most electric pressure washers need at least 4L/min flow from your tap to operate properly, and Australian mains pressure varies by area.
- 2For driveways and concrete, you need at least 1800 PSI — anything less struggles with oil stains and embedded dirt on Australian sandstone or exposed aggregate.
- 3Electric models (1400–2300 PSI) suit suburban homes for cars, decks, and fences. Petrol models (2500–4000 PSI) are for large properties, farm equipment, and commercial-grade concrete.
- 4Water restrictions apply in parts of Australia — pressure washers use 5–8L/min compared to 15–20L/min for a garden hose, so they're actually more water-efficient, but check your local council rules.
- 5Look for units that include a turbo nozzle (rotary tip) and a surface cleaner attachment — the turbo nozzle strips grime 3x faster than a standard fan tip, and the surface cleaner prevents streaking on flat areas.

Editor's Note
Karcher and Gerni dominate Australian hardware stores (Bunnings stocks both extensively), while Ryobi offers strong value through the ONE+ battery ecosystem. For most suburban Australian homes, a 2000 PSI electric unit handles driveways, cars, wheelie bins, and outdoor furniture without the noise, fumes, and maintenance of petrol. Petrol models make sense only for large rural properties or if you're cleaning more than 100m² of concrete regularly. Buy before spring — prices spike in September when everyone wants their patio clean.
Frequently Asked Questions
What PSI pressure washer do I need for an Australian driveway?
For standard concrete and exposed aggregate driveways common in Australian homes, 1800–2300 PSI is the sweet spot. This handles dirt, mould, tyre marks, and light oil stains. For heavily stained commercial concrete or removing paint, step up to 2500+ PSI with a petrol model.
Can I use a pressure washer during water restrictions in Australia?
In most Australian states, pressure washers are allowed even during Level 1–2 water restrictions because they use less water than a garden hose (5–8L/min vs 15–20L/min). However, rules vary by council — check your local water authority's website. Some areas require a trigger nozzle, which all modern pressure washers include.
Is electric or petrol better for a pressure washer in Australia?
Electric suits most suburban Australian homes — quieter, lighter, no fuel mixing, and 1800–2300 PSI handles cars, driveways, and decks. Petrol (2500–4000 PSI) is only worth the extra cost, noise, and maintenance for large rural properties, farm machinery, or commercial cleaning.
What pressure washer do professionals use in Australia?
Professional cleaners in Australia typically use petrol pressure washers rated 3000–4000 PSI with 15L/min flow rates, often from brands like Karcher Pro, Spitwater, or Kerrick. These units cost $1,500–$5,000+ and are overkill for residential use.
