Honda GX390 Pressure Washer Review

Quick Summary

The Honda GX390 is an industrial-style gas-powered pressure washer that provides high pressure, excellent durability and a wide range of movement, giving you an excellent cleaning tool that can deal with almost any surface. Best of Machinery have put this Honda GX390 Pressure Washer review & buyers guide together to give potential buyers more insight into its strengths, flaws, and general performance, helping you decide whether it’s a product that’ll meet all your requirements.

Key Features

The GX390 uses a powerful Honda engine that acts as the central section of the unit’s entire design, meaning that it doesn’t stick out or make it feel heavier in an awkward place – it’s right next to the strong 13-inch pneumatic wheels, giving it an ideal center of gravity that makes it easy to wheel around on even the most uneven surfaces.

The oil alert system automatically shuts down the engine when the oil drops below a safe level, meaning that you won’t accidentally run the engine when it’s out of lubricant – an excellent utility for people who aren’t used to their washing tools needing lubricant and fuel to function properly.

The washer comes with five interchangeable nozzles, which match the standard color-coding rules that most pressure washer nozzles use. These allow for up to 40 degrees of deviation, letting you choose between precise streams or a wide spray to deal with all kinds of different surfaces, stains, and dirt, taking only a few seconds to swap between.

Not only that, but it comes with its own spray gun that can deal with small spaces and hard-to-reach areas, letting you use quickly to hose down a smaller area without needing to use the full force of the main hose.

The default 50-foot hose is able to bend and curve at almost any angle, so you can easily reach high surfaces and roof areas without needing to carry the entire units upstairs – it’s also surprisingly durable, and can take a lot more punishment than other types of hose before showing signs of wear and tear. The frame itself is also fairly durable without feeling too heavy or bulky, being easy to carry and difficult to damage in day-to-day use.


  • Strong, durable design and parts.
  • Powerful engine with automatic low-oil alert.
  • Five easy-to-swap nozzles.
  • Lightweight and easy to carry or wheel around.


1. No separate detergent tank.
2. No extra shell to protect the engine from bumps and direct damage.

Who is it Suitable For?

This washer is an odd mix of a simple design and a versatile set of accessories so it could be a useful tool for anybody who’s got some past experience with operating and using a Honda pressure washer. The fact that it automatically shuts off when it’s low on lubricant means that you won’t get caught off guard if you’re not used to using fuel-based washers so it can be a great choice if you’re using one for the first time.

However, it’s still powerful enough to work well for difficult jobs, so it’s definitely not just a beginner’s tool – the five different nozzles let you use it in a variety of different situations, both for small cleaning tasks and larger jobs that need a much wider spray of water.

Why we like It

The Honda GX390 offers a surprisingly high amount of power in a small frame, and the engine is probably the heaviest part of the entire pressure washer – this means that it’s not only lightweight when compared to other models, but is also easy to repair if something breaks, since you don’t need to struggle with lots of heavy frame pieces to replace damaged parts.

It’s simple to use, even if it’s your first time using a non-electric pressure washer (or even a pressure washer in general), and the fact that most of its parts are exposed can make it much easier to identify problems if it suddenly seems to stop working.

Best of Machinery can’t make your purchases for you, though – this Honda GX390 Pressure Washer review & buyers guide should hopefully give you the extra details you need to decide whether or not it’s the right product for you.
