Collection Description
Commercial Petrol Pressure Washers & Cleaners
Tackling heavy industrial grime, civil construction mud, and expansive concrete hardstands requires uncompromising blasting power and absolute mobility. When working on remote job sites, agricultural properties, or sprawling municipal grounds, reliance on electrical outlets is simply not an option. Commercial Petrol Pressure Washers deliver extreme off-grid cleaning capabilities. Engineered with high-torque 4-stroke engines and heavy-duty triplex pumps, these machines provide the massive PSI (pressure) and high LPM (water flow) required to shear polymerized dirt from surfaces faster than any electric alternative.
Unrivaled Power & Industrial Durability
Standard domestic petrol washers feature lightweight aluminum pumps that quickly overheat and burn out under sustained commercial use. Professional petrol pressure washers bridge this gap by utilizing industrial-grade brass manifold pumps with ceramic plungers. Whether configured as a direct-drive unit for agile transport or a heavy-duty gearbox/belt-drive system designed to run continuously for 8-hour shifts without overheating, these machines are built to survive the brutal conditions of the Australian trade sector.
At Freshway Supplies, we have been a trusted distributor of professional cleaning machinery since 2001. We stock a comprehensive fleet of genuine commercial petrol pressure washers powered by industry-leading engines (such as the Honda GX series). Whether you require a compact unit for a tradesman's ute or a massive 4000+ PSI beast for civil earthmoving equipment, we provide reliable B2B procurement, expert advice, and fast heavy-freight dispatch across Australia.

Frequently Asked Questions
Why choose a petrol pressure washer over an electric one?
The primary advantage of a petrol pressure washer is total off-grid mobility; it requires no electrical outlets, making it essential for construction sites and agriculture. Furthermore, petrol engines generally produce significantly higher PSI and water flow (LPM) than standard 240V electric machines.
What is the difference between PSI and LPM?
PSI (Pounds per Square Inch) measures the pressure or stripping force—how hard the water hits the surface to break the bond of the dirt. LPM (Liters Per Minute) measures the water flow—how fast that broken dirt is washed away. For commercial work, high LPM (e.g., 15-21 LPM) is critical for fast square-meter coverage.
Can I draw water from a tank with a petrol pressure washer?
Yes. Most commercial petrol washers feature pumps with suction capability, allowing them to draw water directly from an external buffer tank or IBC tote when mains tap water is unavailable.
What engines are used in commercial petrol washers?
Premium commercial petrol washers are typically powered by globally trusted 4-stroke engines, such as the Honda GX series (e.g., GX200, GX390) or Vanguard engines. These are renowned for their high torque, easy starting, and incredible longevity under heavy commercial loads.
What is the difference between a direct-drive and a gear-drive pump?
A direct-drive pump spins at the same high speed as the engine (approx. 3600 RPM), making it compact but prone to faster heat buildup. A gear-drive or belt-drive pump uses reduction gearing to spin the pump at a much lower speed (approx. 1400 RPM), drastically reducing heat and wear, which is mandatory for continuous all-day operation.
Do petrol pressure washers require 2-stroke or 4-stroke fuel?
Almost all commercial petrol pressure washers utilize 4-stroke engines. This means you use standard straight unleaded petrol in the fuel tank, and a separate oil reservoir lubricates the engine. You do not need to mix oil and fuel together.
How often should I change the pump oil?
Routine maintenance is vital to prevent pump failure. You must change the pump oil after the first 50 hours of operation to remove any initial 'break-in' metal shavings, and then every 500 hours (or annually) thereafter.
What is a rotary surface cleaner accessory?
A rotary surface cleaner is a wide, circular deck that attaches to the end of your pressure wand. It houses two spinning, high-pressure nozzles underneath, allowing you to clean flat concrete driveways and car parks evenly, without tiger stripes, and up to 10 times faster than a standard wand.
Can I use hot water in a standard petrol pressure washer?
No. Standard petrol pressure washers are designed strictly for cold water supply. Running hot water through a standard pump will melt the internal seals and immediately destroy the unit. If you need thermal heat, you must purchase a specialized Hot Water Pressure Washer with an integrated boiler.
How do I maintain my petrol pressure washer when storing it?
To prevent internal corrosion and engine damage during long-term storage, you should run a fuel stabilizer through the petrol tank, squeeze the trigger gun with the engine off to relieve built-up pressure, and drain excess water from the pump to prevent freezing.
Can I request B2B trade pricing for my contract cleaning business?
Absolutely. Freshway Supplies provides structured wholesale trade pricing and volume discounts for commercial cleaning companies, civil construction firms, and agricultural operators looking to procure heavy-duty petrol machinery.
What are the delivery timeframes for heavy petrol machinery?
For metropolitan areas, standard heavy-freight delivery for machinery typically takes 1 to 3 business days. We also offer a highly convenient Click & Collect service from our Arncliffe warehouse in Sydney for urgent equipment procurement before heading to a job site.
