Pressure Washer Trailers

A pressure washer trailer puts the machine, the water and the hoses on one towable chassis — arrive, unhitch, start cleaning. No mounting a skid to a ute, no chasing a tap on site, no loading gear in and out between jobs.

The range covers Australian-made Jetwave trailers from 3000 to 5075 PSI, all Honda petrol powered, with onboard water cartage from 200L to 1000L and high pressure hose reels fitted as standard.

Which pressure washer trailer suits your work?

Three things decide it: how much water you need to carry, what you're towing it with, and how hard the machine has to work. Get the water capacity right and the rest usually follows, because tank size drives the trailer format, and the trailer format drives what you need behind it.

Lite trailer or premium trailer

The two formats answer different problems.

  • Lite trailers run a single axle with a 200L tank so the whole rig stays light and easy to reverse, and a standard work ute tows it without a second thought.
  • Premium trailers run a tandem axle with a 1000L TTi tank so you carry five times the water, and long washdowns finish without a refill run.
  • Tandem axles spread the load across four wheels so the trailer tracks straighter at speed, and a full 1000L tank stays stable on the highway.

The trade-off is weight. A premium trailer runs around 900kg dry and 1850kg wet, so check your vehicle's braked towing capacity before committing. A lite trailer is a far smaller ask. If you work sites with mains water access, the 200L lite format is usually enough — the tank covers you between connections rather than supplying the whole job.

Matching pressure and flow to the job

Pressure breaks the bond, flow carries the mess away. Most operators over-index on PSI and under-value litres per minute.

  • Higher flow rinses a larger area per pass so wide concrete, fleet washing and stockyards clean in fewer passes, and the job finishes sooner.
  • Higher pressure cuts into bonded contamination so paint prep, heavy machinery buildup and hard deposits break loose without extra chemical.
  • The 280-31 models run 31 LPM so they suit high-throughput washdowns where volume matters more than raw pressure.
  • The 350-23 models run 5075 PSI so they suit the hardest surface work where nothing lighter will shift the deposit.

What's included in a turn-key trailer

Every trailer in this range arrives complete. Galvanised Australian-made chassis, Sunraysia-style wheels, quick-release 50mm tow coupling, jockey wheel and spare wheel. Onboard water tank with low-level cut-out and high-flow float valve, so the pump is protected if the tank runs dry. A fitted 30m high pressure hose on a reel, a low trigger force gun, stainless lance and nozzle, and the Jetwave Safety System relief valve. Nothing to source separately before the first job.

Engines and pumps

Hornet models run the Honda GX390 electric start with pull start backup. Senator models step up to the V-twin EFI Honda iGX700 or iGX800 with auto choke, electronic fuel injection and a digital hour meter — easier starting and clearer service tracking across a busy schedule. All models drive a JW UDOR triplex plunger pump at 1450 RPM through a gearbox rather than direct drive, which is the specification that keeps pump life long under daily use.

Frequently asked questions

What can tow a pressure washer trailer?

It depends on the format. A lite trailer with a 200L tank is a light load that most work utes handle comfortably. A premium tandem axle trailer with a full 1000L tank runs close to 1850kg wet, so you need a vehicle rated for that braked towing capacity. Check the wet weight, not the dry weight — water is roughly a kilo per litre.

Do I still need a water supply on site?

Not for the length of the tank. The 200L lite trailers suit sites where you can top up between jobs. The 1000L premium trailers are built for remote work with no mains access. Both have low-level cut-out protection, so the pump shuts down rather than running dry if the tank empties.

Trailer, cube or mounting skid — which format do I need?

A trailer tows behind any suitable vehicle and stays a self-contained unit, so it moves between operators and vehicles freely. A cube or mounting skid bolts into a ute, truck or van tray, which frees up your tow ball and suits operators who already have the vehicle capacity. If your vehicle is committed to other work, or several people share the machine, the trailer is the simpler answer.

Are these trailers registered for road use?

The trailers are Australian made with hydraulic or mechanical disc braking, jockey wheel and spare wheel fitted. Registration requirements vary by state — give us a call on 1300 404 226 and we'll confirm what applies for your setup before delivery.

Do you supply hot water trailer units?

The trailers in this range are cold water petrol machines. Hot water is available in trailer configuration on request — the Executive Silent diesel unit can be supplied on a tandem axle trailer with a 1500L tank. Give us a call on 1300 404 226 and we'll spec it for your application.
