Whether you’re a DIY warrior, a weekend detailer, or a tradie who needs gear that keeps up with the job site, a Giantz high pressure washer offers the kind of cleaning grunt you’ve been looking for. And if you're after large washer capacity, petrol-powered performance, and high pressure water cleaning, you’re in exactly the right place.
Let’s break down why Giantz pressure washers are making waves across Aussie homes, garages, and workshops — and why they might just be your next favourite tool.
What Is a High Pressure Washer, and Why Does Capacity Matter?
Before we get into the nitty-gritty, let’s cover the basics. A high pressure washer (also called a pressure cleaner) uses a pump to shoot out water at high speed. This concentrated blast is powerful enough to remove oil stains, baked-on dirt, mould, and even paint in some cases.
But here’s where washer capacity matters. Larger models come with more robust water flow rates (usually measured in litres per minute) and bigger motors or engines. This means they can clean more efficiently, tackle larger surface areas, and run longer without needing a break. It’s the difference between cleaning your BBQ and cleaning your whole driveway — and doing it without breaking a sweat.
The Power of Petrol: Why Go for a Petrol High Pressure Washer?
There are two main types of pressure washers: electric and petrol. While electric washers are fine for light jobs, they don’t always have the muscle for serious grime.
That’s where a high pressure washer petrol model shines. Petrol-powered washers offer:
- Higher pressure and flow rates — perfect for heavy-duty jobs.
- No reliance on power cords or outlets, making them ideal for remote or large properties.
- More durability — they’re built for frequent, rugged use.
So if you’re blasting caked-on dirt from machinery, stripping grime off patios, or even prepping surfaces for paint, a petrol washer is a no-brainer.
