In this guide, we’ll dive into everything you need to know about high pressure water cleaning, especially focusing on petrol-powered units, large washer capacity models, and what makes Giantz one of the top names on the market. We’ll also walk you through how to pick the largest washer that suits your needs — and why size and pressure really do matter.
Why Choose a High Pressure Washer?
Let’s be real: scrubbing driveways with a brush and hose just doesn’t cut it. A high pressure washer turns a laborious job into a fast and oddly satisfying task. Whether you’re blasting mildew off your deck, cleaning your ute after a muddy weekend, or restoring pavers to their original glory — these machines save time, water, and elbow grease.
Key Benefits:
- Time-saving: Clean larger areas faster.
- Water-efficient: Use up to 80% less water than a garden hose.
- Better results: High pressure lifts dirt, grime, mould, and oil stains with ease.
- Versatile: Ideal for driveways, walls, tools, vehicles, fences, and even house exteriors.
Meet the Muscle: Giantz High Pressure Washers
When it comes to reliability and brute force, Giantz doesn’t mess around. Their high pressure washers are known for combining power with great value, making them one of the most popular brands for Aussie homes and job sites.
Why Giantz?
- Engineered for Aussie conditions: Tough enough to handle hot summers, dusty environments, and hard surfaces.
- Affordable pricing: Great value without compromising performance.
- Range of models: From light-duty to commercial-grade options.
- Petrol and electric choices: With high pressure washer petrol models available for those who need more grunt and portability.
Petrol vs Electric: Which One Should You Choose?
While electric washers are perfect for light cleaning around the house, petrol-powered pressure washers are where things get serious. These are the machines you want when you’re facing tough, large-scale jobs and need unrestricted movement.
Petrol High Pressure Washer Advantages:
- Higher power output: Ideal for industrial or large residential jobs.
- No power cord: Great for remote areas or big outdoor spaces.
- Durability: Petrol engines often handle more abuse and last longer.
- Ideal for tradies: More pressure, more reach, and more cleaning capability.
If you’ve got big cleaning plans, like long driveways, outdoor walls, or workshop floors, a Giantz high pressure washer petrol model is the way to go.
Understanding Large Washer Capacity
When shopping for pressure washers, one spec you don’t want to overlook is the washer capacity — essentially, how much water the machine can process and spray per minute.
A large washer capacity means:
- More cleaning in less time
- Stronger water flow (measured in litres per minute or L/min)
- Better coverage for wide or heavily soiled areas
Many of the largest washers in the Giantz range boast flow rates of up to 12L/min or higher, paired with pressure ratings exceeding 4000 PSI. That’s enough power to remove oil from concrete, strip paint, and even clean heavy machinery.
Top Features to Look For in a Giantz High Pressure Washer
Not all washers are created equal. When choosing a machine, here’s what to keep an eye out for:
1. PSI Rating (Pounds per Square Inch)
The higher the PSI, the more pressure it delivers. For heavy-duty work, look for 3000+ PSI.
2. Flow Rate (L/min)
A large washer capacity of 8–12 litres per minute ensures a solid water stream to match the pressure.
3. Motor/Engine Type
For serious power, go for a petrol high pressure washer with a 4-stroke engine. Giantz often uses air-cooled OHV motors for reliability.
4. Durable Hose and Lance
Look for reinforced hoses and steel spray guns that can handle high pressure without bursting.
5. Nozzle Options
Interchangeable nozzles (0°, 15°, 25°, 40°) allow you to adjust spray patterns for different cleaning tasks.
6. Wheels and Portability
These machines can get heavy. Big rubber wheels and sturdy frames make transport easier — especially if you’re working around a large property.

How to Use a High Pressure Washer Safely
Power is great — but with great PSI comes great responsibility. Follow these tips to stay safe and get the best results:
- Always wear eye protection.
- Start with a wider spray nozzle (like 40°) and move closer as needed.
- Avoid delicate surfaces with narrow-angle nozzles — they can damage paint, timber, or skin.
- Use detergent sparingly and rinse thoroughly.
- Never aim at people, pets, or electrical outlets.
Maintenance Tips to Extend Your Washer's Life
Like any machine, a bit of maintenance keeps your Giantz washer running smoothly for years.
- Check and change engine oil regularly (for petrol models).
- Flush the hose and nozzle after use to prevent clogs.
- Store it in a dry place to avoid rust or water damage.
- Clean filters and inspect hoses every few uses.
