One of the two types of pressure washers that you will commonly come across is the gas-powered variety. These models have a few advantages over their electric counterparts, but there are also some cons to them. Before we get to our review, we are going to take a look at some of these aspects.

One of the main reasons that a gas pressure washer model is preferable to an electric model is because it does not require a cord to maintain power. This gives you much more freedom of movement. As long as you bring gasoline with you, you will be able to power your gas pressure washer nearly anywhere.


Unfortunately, all of this gas will have to be stored somewhere while it is not being used with your pressure washer. Since you need to find sufficient storage room for your pressure washer and your gasoline, these are not recommended for customers for whom space is at a premium.

Keep in mind that gas pressure washer models tend to be larger than their electric counterparts so that you will need even more storage room already. These models, which feature a gasoline engine instead of an electric motor, tend to be more powerful, but the question you will have to ask yourself is whether you will end up making use of that power.

Gas pressure washers are usually ideal for customers who have to clean out areas that are highly resilient and will require even more pressure than usual. Remember that higher pressure will mean a greater danger to you in the event of misuse, so you should ensure that you are comfortable using pressure washers before opting for one of these models.

Before we get to our review, we will take a look at an aspect which is crucial to finding the ideal model of pressure washer.


It is important to find a pressure washer which features sufficient portability. Since gas models tend to be larger and more cumbersome, they tend to suffer from portability issues more so than electric pressure washers. That is why many of them are mounted on small carts which have wheels attached.

The type of wheels on your pressure washer’s cart will also affect how portable it is, as different wheels will be more amenable to certain types of terrain. For example, pneumatic tires will be better suited for rough terrain as they will be able to adapt to it with more ease than solid wheels.


Pneumatic tires, however, will have the disadvantage of being more vulnerable than other types of wheels. A solid wheel will not have to deal with flat tires. Before making your purchase, you should consider what kind of terrain you will be using your pressure washer on and buy one which best fits your needs.

Portability is dependent on more than just the presence of tires or wheels, however. If you want a model which is easier to bring around with you, try and find one which has a handle or something that makes the pressure washer easier to carry (if it is light enough to be carried).

About The Product

If you need the best gas pressure washer around, this model is your best option. It is made by Simpson, a brand which is known for making reliable and effective products. You will rarely come across a pressure washer which offers greater value for money than this model. Some notable features:

  • The jet of water features a pressure of 3100 psi at 2.5 gpm
  • Features a high-pressure hose which can resist kinks and abrasion
  • Features five nozzles for different applications
  • This model is mounted on 10” pneumatic tires for better portability
  • Features a safety lock
  • Features separate warranties for the engine, the pump, and the frame
  • Comes included with a siphon tube for your detergent


This model features the most extra features that we have seen on a pressure washer which is powered by a gasoline engine. While these models tend to be less user-friendly, you could almost assume that this product was an electric pressure washer if it wasn’t for the noise and the high power output.


While it certainly is noisy enough to let you know that it is powered by an engine, this product is more silent than most other gas-powered models. This feature is useful for those of us who intend to use it often, as you will not end up having to wear ear protection around it.

The 10-inch pneumatic tires make this model much more portable than the other counterparts you will find which are powered by gasoline. Unlike other models, which feature rigid wheels, these tires are ideal for all conditions so you can even take this pressure washer out onto a work site.

What Others Say

We also looked at customer reviews and testimonials to get a feel for how this model was received. Most customers were impressed by the ease of setup for this example, as gas-powered pressure washers tend to feature a complicated startup and break-in process, but that is not the case here.

While there were a few negatives, most of them were inconsequential. Some customers described this model as being too powerful, as it can peel the paint right off of wood. There were also some issues with parts not being shipped correctly, but these problems were quickly rectified by Simpson.

Buying Advice

As with most gas pressure washers, this model is also more expensive than most electric washers.
