Jet-USA DX800 Commercial Diesel High-Pressure Washer

Product Overview

The Jet-USA DX800 is built for buyers who want serious cleaning performance for demanding jobs around workshops, farms, larger properties, and commercial spaces.
With its high-torque diesel engine, commercial-grade triplex pump, and heavy-duty trolley frame, it is designed to handle tougher cleaning work with confidence.

Why This Pressure Washer Stands Out

What makes the DX800 especially appealing is the way it combines diesel efficiency with serious pressure washer capability.
It is not just built to blast away grime. It is also set up for stronger day-to-day durability with a brass-head triplex pump, anti-vibration support frame, and a steel-braided hose that suits harder use.

10HP Diesel Power for Heavy-Duty Work

At the heart of the DX800 is a 418cc diesel engine delivering 10 horsepower.
That gives it the kind of all-day work-ready feel many buyers want when cleaning tasks go well beyond light household jobs.

Electric Start Convenience

One of the most practical features on this model is its electric start system.
Instead of relying only on pull-starting, the DX800 is designed to get going quickly and easily, while recoil backup is there when needed.

4000 PSI Maximum Pressure

The DX800 is rated to a maximum pressure of 4000 PSI, with a continuous pressure output of 3600 PSI.
That puts it firmly in the category of machines built for serious exterior cleaning rather than casual rinsing.

Strong 17L/min Flow Rate

Pressure matters, but water flow matters too. With a listed flow rate of 17 litres per minute, this machine is designed to move a serious volume of water, which helps make larger cleaning jobs more effective and more efficient.

Commercial-Grade Brass Triplex Pump

Jet-USA highlights a commercial-grade triplex pump with a brass head, which is one of the more important parts of this washer’s overall appeal.
This style of pump is aimed at stronger durability and more reliable ongoing output than lighter-duty alternatives.

15m Steel-Braided Hose

The included 15 metre steel-braided high-pressure hose gives you useful reach for larger jobs.
It helps reduce the need to constantly move the unit when working across wider areas such as concrete yards, walls, driveways, or machinery wash-down zones.

5 Pro-Tip Nozzles for Different Tasks

The DX800 comes with five quick-connect Pro-Tip nozzles: 0°, 15°, 25°, 40°, and soap.
That gives you flexibility across different jobs, whether you need concentrated cutting power, broader rinse coverage, or detergent application.

Built for Control and Practical Use

Jet-USA also includes a pro spray gun with a horizontal foregrip, which is designed to improve control and reduce fatigue during longer cleaning sessions.
That is a useful detail on a pressure washer intended for more demanding work.

Heavy-Duty Trolley Frame

The DX800 is built on a strong tubular steel trolley frame with a powder-coated finish.
This gives it a rugged, commercial-style feel and helps it stand up better to tougher conditions around farms, worksites, and larger properties.

Anti-Vibration Support Frame

Beneath the pump sits a dedicated anti-vibration support frame designed to reduce movement under load.
That helps the machine feel more stable while also supporting longer-term durability during heavier operation.

All-Terrain No-Flat Tyres

The 10-inch all-terrain no-flat tyres make this model easier to move over rougher ground without the worry of punctures.
That makes a real difference if you need to wheel the washer around sheds, gravel, paddocks, or uneven outdoor areas.
