Jet-USA TX870 Gen IV 5000PSI Commercial Petrol High Pressure Washer

Product Overview

The Jet-USA TX870 Gen IV is built for buyers who want serious outdoor cleaning power for demanding jobs around the home, farm, workshop, or worksite.
With its 15HP 420cc four-stroke engine, commercial-style pump setup, and strong 5000PSI maximum pressure, it is designed to tackle stubborn grime with confidence.

Why This Pressure Washer Stands Out

What makes the TX870 especially appealing is the way it combines serious cleaning force with a rugged, work-ready build.
It is not just about headline pressure. This machine also features an Italian-made adjustable AR RSV series triplex pump, a long reinforced hose, and practical mobility features that make it easier to use across larger outdoor areas.

5000PSI Maximum Pressure

The standout figure here is the 5000PSI maximum pressure, backed by a continuous pressure rating of 4207PSI.
That gives the TX870 the kind of cleaning force buyers usually want for tougher work such as blasting paths, driveways, stonework, machinery, and hard exterior surfaces.

15HP 420cc Four-Stroke Engine

At the heart of the TX870 is a powerful 420cc air-cooled four-stroke OHV engine producing 15 horsepower.
It is designed to deliver strong and reliable performance for demanding cleaning tasks while still keeping operation practical with recoil starting.

Italian-Made AR RSV Series Pump

One of the big reasons this model feels more serious is its adjustable Annovi Reverberi RSV series pump made in Italy.
This triplex brass-head pump is designed for sustained pressure and long-term durability, making it especially appealing for buyers who want more than an entry-level washer.

Strong Flow Rate for Faster Cleaning

With a listed flow rate of 15 litres per minute, the TX870 is built to move plenty of water as well as pressure.
That combination helps make cleaning more effective and more efficient across larger outdoor surfaces.

Heavy-Duty 20 Metre Hose

The 20 metre dual-layer wire-braided hose gives this washer excellent working reach.
That makes it easier to clean longer driveways, roofing edges, walls, and broader outdoor spaces without having to constantly move the machine around.

5 Pro Tip Nozzles Included

The TX870 comes with five Pro Tip nozzles: 0°, 15°, 25°, 40°, and soap.
That gives you useful spray flexibility depending on whether you need concentrated pressure for tougher grime, broader coverage for general cleaning, or lower-pressure detergent application.

Built for Tougher Jobs

Jet-USA highlights this model as ideal for serious work, and the spec sheet supports that.
It is the kind of machine suited to tasks like cleaning cars, windows, paths, paved areas, stonework, and other surfaces where strong pressure and a durable setup matter.

Rugged Frame and Easy Mobility

The compact upright design, rugged tubular frame, and oversized 13-inch by 5-inch flat-free all-terrain tyres help make the TX870 easier to move around a job site or larger property.
The soft-grip handle and balanced frame add to that everyday usability.

Practical Safety and Durability Features

This pressure washer also includes helpful practical touches such as low oil shutdown, a safety gun trigger lock, a rotating handle, brass fittings for corrosion resistance, and rubber feet and engine mounts for smoother operation.
These are the kinds of details that add to its work-ready feel.
