If your cleaning jobs never happen in the same spot twice, a pressure cleaner trailer is the smartest gear you can buy. Hook it to your ute, tow it to the job, and start blasting no power point, no mains water, no dramas. At OEM Group®, we build and assemble our pressure cleaner trailers right here in Western Australia. Each unit pairs a genuine, Australian-made SPITWATER pressure cleaner trailers with a fully galvanised, heavy-duty trailer and a 1000L water tank. The result is a complete mobile washdown unit that’s ready to work the moment it leaves our yard.
Our trailers handle the jobs that break lesser machines:
Because everything is onboard water, power, pump, hoses, and reels one operator can set up and start cleaning in minutes. There’s no waiting on site services and no juggling separate gear across the tray of your ute. That saves real time on every job, every day. They’re trusted by some of the biggest names in Australian mining and logistics, and they’re built to keep working long after the job gets ugly. That’s why crews from the Pilbara to Perth choose OEM Group® when it’s time to buy.

Plenty of suppliers will sell you a pump strapped to a trailer. We build complete cleaning systems designed for the harshest conditions in the country and we back them long after the sale.
Every trailer runs a real SPITWATER machine, made in Australia with steel and brass components where others use plastic. Operating pressure sits at 3000 PSI (200 BAR) with flow rates of 15 or 21 litres per minute, driven by reliable Kubota diesel engines. Hot water models like the Hottie IV and Hottie V cut through grease and oil that cold water can’t touch.
Our Workmate Hottie was custom built to mine specifications, with off-road wheels rated to 2.8 tonne. If your site has its own requirements, our custom design and fabrication team can build a trailer to match them exactly.
Buying the trailer is just the start. Our factory-trained technicians handle servicing and repair from our Perth and Karratha branches, so your unit stays on the job instead of in the shed. We also stock FlowRPM chemical solutions matched to your machine, which means better cleaning results without damaging your pump.
Not ready to buy outright? Flexible financing plans are available, or you can hire a SPITWATER pressure cleaner first and put it through its paces on your own site.

Picking the right unit comes down to three questions. Answer these and you’re most of the way there.
Cold water units handle dirt, mud, and general grime with ease. If that’s your daily work, a cold water model like the SPITWATER TSA-15210DEM will serve you well.
Hot water changes the game for grease, oil, and hydrocarbons. Heat breaks down the bond between the muck and the surface, so you clean faster with less chemical. For workshops, mine plant, and transport fleets, a hot water trailer like the Hottie IV or Hottie V pays for itself in saved hours.
Pressure (PSI) does the cutting. Flow (litres per minute) does the rinsing. For heavy industrial washdowns, you want both. Our standard trailers deliver 3000 PSI with 15 or 21 L/min flow enough to strip caked-on material from earthmoving gear without hanging around. For drain and pipe work, the Wombat Jetter steps up past 4750 PSI with flow above 22 L/min.
If you’re towing to remote sites, look for a big onboard tank, off-road rated running gear, and diesel power. Every OEM Group® trailer comes standard with a 1000L polyethylene water tank with top fill, double wire braided high-pressure hoses on heavy-duty reels, and a quick-release coupling that fits a standard 50mm tow ball. Fill it, hitch it, go.
A well-kept trailer will outlast several cheap ones. Check hoses and fittings for wear before each shift, keep the water filter clean, and top up fuel and oil before long runs. Because our units are built with serviceable steel and brass parts rather than throwaway plastic, most wear items can be repaired instead of replaced. And when it’s due for a proper service, our Perth and Karratha workshops can handle it or we’ll come to your site.
Still not sure which model fits your work? That’s what we’re here for. Our team has spent decades matching equipment to Australian job sites, and we’d rather ask you a few questions now than sell you the wrong machine.
OEM Group® fabricates heavy duty pressure cleaner trailers for safe and portable pressure cleaning solution.
Our pressure cleaner trailers are used every day in mining, transport, council maintenance, and commercial cleaning. Major operators such as BHP, Rio Tinto, and Fortescue rely on SPITWATER equipment on their sites, alongside councils, contractors, and family businesses across Australia. When a trailer has to perform in heat, dust, and rough terrain, reliability isn’t a nice-to-have — it’s the whole point of buying one.
A Pressure Cleaner Trailer 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
Ready to buy? Shop the full pressure cleaner trailer range here in Australia and compare hot and cold water models by pressure, flow, and tank size until you find the right fit for your site. Every trailer is backed by genuine SPITWATER parts and honest advice, so you’re never left guessing whether you picked the right one.
Machines work harder when they are 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 pressure cleaner running at full power and helps it last for years instead of months. We keep genuine Pressure Cleaner Trailer parts in stock, plus fittings to suit most other brands, so a common repair does not 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 when you need one, without the upfront cost of buying. Hiring is also a smart way to test a model on your own site before you commit to it, or to cover a busy period without adding gear you will not use later.
When you call OEM Group®, you talk to people who understand the machines and the work they do. We are based in Western Australia, with branches in Perth and the Pilbara, so help is close by when you need it. From picking the right unit to keeping it running for years, you get straight answers and quick support. That is the kind of backup you simply do not get from a faceless website.
From fleet washdowns to on-site cleaning see how SPITWATER Pressure Cleaner Trailer 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.
