Heavy-duty and fuel-efficient, diesel models are built for continuous industrial use. Available in hot or cold water, with long runtimes and lower total cost of ownership.
A diesel pressure cleaner is the machine businesses reach for when a job needs serious power for hours on end, not just a quick blast a few times a week. At OEM Group, our SPITWATER diesel pressure cleaner range is built for mine sites, transport yards, farms, and any operation that needs a machine to work a full shift without slowing down. These are heavy-duty units made for tough Australian conditions, not light-duty gear that gives up after a season. Standalone or trailer-mounted, we can match you with the right diesel pressure cleaner and back it with local service, parts, and support.
This page keeps it simple. We walk you through how to choose the right machine, what makes a quality unit worth the money, and how to buy, hire, or service one through our WA-based team. No jargon, no filler — just what you need to make a smart choice.
Not every diesel pressure cleaner suits every job. A compact unit built for a single ute might struggle across a busy wash-down bay, and a heavy-duty trailer rig is more machine than you need for occasional use. Three things decide which model is right for you: how it fits your workload, the water temperature, and the pressure and flow. Buy for the work you actually do, not the work you think you might do one day.
Diesel earns its place on a site where power is the priority and mains electricity isn’t an option:
If your site has reliable power and the work happens indoors, an electric pressure cleaner or petrol pressure cleaner might suit you better. For continuous outdoor use where reliability matters most, diesel is hard to beat.
Cold water diesel units handle dirt, mud, dust, and general wash-downs without any trouble, and they usually cost less to buy. Hot water models cut through grease, oil, and baked-on grime much faster, since heat softens the mess so the water does more of the work. That means less chemical and a faster finish. If you clean engines, greasy machinery, or transport equipment, hot water is worth every cent. For plain dirt and mud, cold water is usually all you need.
Pressure, measured in PSI, is the punch that lifts stuck-on dirt. Flow, measured in litres per minute, is how much water rinses that dirt away. High pressure with lower flow suits detail work and smaller areas. For big surfaces and heavy build-up, you want strong numbers on both. Too little of either and you’ll be standing there far longer than you should. If you’re not sure what suits your work, our team can size a unit for you in a quick phone call.
There’s a big gap between a budget diesel unit and a proper industrial diesel pressure cleaner. The price difference is real, but so is the value you get back. A powerful machine cleans faster, lasts longer, and costs less to keep running over its life.
Our SPITWATER diesel units are made with steel and brass parts, not plastic. That’s the single biggest reason they keep working season after season. Cheap machines cut corners on the pump, and the pump is the part that fails first. Spend once on the right machine and you’re not back at the shop in six months looking for a replacement.
Marketing lists a hundred features, but only a handful change your day:
The sticker price is the easy number to compare, but it’s not the one that matters most. A cheap machine that fails twice a year costs you in repairs, downtime, and lost hours on the job. A well-built diesel pressure cleaner that runs efficiently and rarely stops is almost always the cheaper choice over three to five years. Buy once, buy well, and the machine quietly saves you money every week it’s on site.
Explore our full range of Diesel Pressure Cleaner models—each purpose-built to suit different site needs, from enclosed workshops to remote mining camps.
Our machines are used every day in mining, transport, agriculture, 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 isn’t a nice to have? it’s the whole point.
A diesel pressure cleaner 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 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. See how it all fits together on our cleaning equipment page.
Choosing the machine is only half the job. What happens after you buy matters just as much, and it’s 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.
Machines work harder when they’re looked after. Our WA-based technicians handle servicing and repairs for all major brands, either on your site or at our Perth workshop. Regular servicing keeps your diesel pressure cleaner running at full power and helps it last for years instead of months. We keep genuine SPITWATER parts in stock, plus fittings to suit most other brands, so a common repair doesn’t leave you waiting weeks for a part to ship in.
Only need a machine for a short job, or want to stay productive while yours is in for repair? Our equipment hire options let you grab a unit without the upfront cost of buying, and it’s a smart way to test a model on your own site before you commit.
When you call OEM Group, you talk to people who understand the machines and the work they do. We’re based in Western Australia, with branches in Perth and the Pilbara, so help is close by when you need it — the kind of backup you don’t get from a faceless website.
A quality diesel pressure cleaner pays for itself in time saved, jobs done properly, and gear that keeps going year after year. Shop the range today, or contact our team for a quick chat about what suits your site. Whether you’re after a single machine or fitting out a whole fleet, we’ll help you get it right the first time.
For general washdowns and light industrial use, a mid-range unit is plenty. For heavy grease and daily industrial build-up, look for strong pressure and flow together, and consider hot water.
Diesel suits sites with no mains power and heavy daily use, since it runs longer on less fuel than petrol and doesn't need a power point like electric. If your site has power and the work is indoors, electric might be the better fit.
Yes. Diesel engines are built for continuous, heavy-duty running, which is exactly why they're the standard choice on mine sites, transport yards, and farms across Australia.
It depends on the hours you run it, but regular servicing pays for itself by preventing bigger faults and keeping the pump and engine healthy.
Yes. Our equipment hire service lets you trial a model on your own site before committing, or keep working while your own unit is in for repair.
