A Pressure Washer is a cleaning machine that pumps water at high velocity through a narrow nozzle to blast away grime, oil, grease, mud, and built-up debris that ordinary washing simply can’t shift. Industrial-grade units like the SPITWATER range supplied by OEM Group® are engineered with a rugged frame, premium-grade pump, and intuitive controls, and are available in electric, petrol, diesel, hydraulic, and trailer-mounted configurations so the machine matches the site rather than the other way around. Built using steel and brass components rather than plastic, a commercial Pressure Washer is designed to run day after day across workshops, heavy machinery, fleet vehicles, and yards a genuine piece of plant equipment, not a hardware-store accessory. You can view the full range of heavy-duty options on the SPITWATER Pressure Washer.
The main advantage of a Pressure Washer is that it does more work in less time while using less water than a running hose, because pressure not volume does the cleaning. That efficiency translates directly into reduced downtime on plant washdowns, fleet cleaning, workshop floors and yard maintenance, and it removes the need for manual scrubbing that slows crews down and creates injury risk. Hot water models take it further by cutting through oil and grease that cold water simply pushes around, which makes them a favourite in transport, mining, food processing and agriculture. Machines built for Australian conditions also hold their value longer, and a well-maintained unit backed by local parts and technicians keeps performing job after job see the wider Cleaning Equipment & Servicing range.
Not every pressure washer suits every job. A unit that’s perfect for a small workshop can struggle on a mine site, and a big diesel machine is overkill for a quick car wash. Three things decide which model is right for you: the power source, the water temperature, and the pressure and flow. Get these three right and everything else falls into place. If you only take one thing from this section, make it this buy for the work you actually do, not the work you think you might do one day.
Your power source shapes where and how you can use the machine. It affects how mobile the unit is, how much noise and fumes it makes, and how long it can run in one go. OEM Group stocks four main types, so you can match the machine to your site instead of forcing your site to suit the machine.

PSI (pounds per square inch) tells you how hard your Pressure Washer hits the surface, and the fastest way to check it is to read the compliance plate or data sticker on the machine, which lists the rated working pressure alongside flow rate in litres per minute. For a live reading, fit an inline pressure gauge between the pump outlet and the hose, run the unit at full throttle with the trigger open, and compare the result against the rated figure a drop usually points to a worn nozzle, blocked inlet filter, air in the line, or a tired unloader valve. Remember that PSI alone doesn’t equal cleaning power; it works in combination with flow rate, so a balanced machine will always outperform a high-PSI unit with weak flow. If your readings are falling short, the Servicing & Repair team can test and restore performance.
Choosing between a petrol and a diesel Pressure Washer comes down to how mobile you need to be and how many hours the machine will run. Petrol models are lighter, easier to start and simple to mount on a ute or trailer, making them the practical pick for remote or rugged sites where there’s no power and the work is intermittent pair them with a water tank and you’re completely off-grid. Diesel units are the workhorses: heavier and higher in upfront cost, but far more fuel-efficient over long runtimes and built for continuous industrial duty, with hot and cold water options and a lower total cost of ownership across the machine’s life. As a rule of thumb, choose petrol for portability and short bursts, and diesel for all-day, heavy-duty cleaning.
A Pressure Washer is a powerful tool and the water stream can cause serious injury, so treat it with the same respect you’d give any high-energy equipment: wear eye protection, gloves and closed footwear, never point the gun at people or animals, and never use your hand to test the spray. Before starting, check hoses and fittings for damage, confirm the water supply is on and the inlet filter is clean, and release trapped pressure through the trigger before disconnecting anything. Start at a wide fan pattern and a safe distance, then move closer only as needed to avoid gouging paint, timber or seals, and keep petrol and diesel units in well-ventilated areas away from ignition sources for confined or hazardous spaces, use an electric or hydraulic model instead. If you only need a unit occasionally or yours is in for repair, equipment hire keeps you productive without the downtime.
A powerful pressure cleaner earns its keep in the hardest settings. Our machines are used every day in mining, transport, agriculture, food processing, construction, and commercial cleaning. Major operators such as BHP, Rio Tinto, Fortescue, and Cleanaway run SPITWATER units on their sites, alongside plenty of smaller trades and family businesses. When gear has to perform in heat, dust, and long shifts, reliability is not a nice-to-have — it is the whole point. A machine that breaks down mid-job costs you far more than it saved at the checkout.
A pressure washer works even harder with the right add-ons. Pair yours with FlowRPM chemical solutions to shift stubborn grease and grime faster and with less scrubbing. Add VACSTORM floor cleaners to dry and finish an area cleanly after a washdown, which matters a lot for safety in busy workshops. And if you need to move your gear around a site, a pressure cleaner trailer turns any unit into a complete mobile wash station, built and assembled right here in WA. You can see how it all fits together on our cleaning equipment page, where the full lineup sits side by side.
Choosing the machine is only half the job. What happens after you buy matters just as much, and it is where OEM Group stands apart from online-only sellers. You get real people, local service, and genuine parts — not a box on a doorstep and a phone number that goes nowhere

From fleet washdowns to on-site cleaning—see how SPITWATER pressure washer perform across industries.
For light cleaning, cars, and general dirt, a mid-range unit is plenty. For heavy grease, machinery, and industrial build-up, look for strong pressure and flow together, and consider hot water. When in doubt, tell us the job and we will match the numbers to it.
Go electric for indoor and power-connected work, petrol for mobile and off-grid jobs, and diesel for heavy daily use where running cost matters. Hydraulic suits sites where fumes or engines are a problem.
Yes. Electric hot water units are a good fit because they run without exhaust fumes and keep noise low, which suits food processing and indoor spaces.
It depends on the hours you run it, but regular servicing pays for itself by preventing bigger faults and keeping the pump healthy. Our team can set up a simple schedule that suits how hard you work the unit.
