But before we reveal our list of the best commercial pressure washers, we will help you gain a deeper understanding of these machines. We’ll cover the different types and the factors that we took into consideration when making our list of the best. By the end of this article, you’ll know everything you need to know before making a decision!

What Is A Commercial Pressure Washer?

A commercial pressure washer is one that is used for industrial cleaning jobs. Usually, these are used for cleaning dirt, oil, and grime off of industrial equipment, business establishments, and commercial vehicles.

Compared to residential pressure washers, these offer more power and durability to handle tough cleaning jobs and resist heavy wear and tear. They are used in all sorts of industries, including automotive, farming, manufacturing, food service, and more. Any industry that needs efficient, high-powered cleaning will rely on these.

Another common difference between a commercial vs. residential pressure washer is the number of operators each can accommodate. A residential pressure washer will have just one wand/hose, and that is enough for general cleaning jobs. A commercial pressure washer, on the other hand, can come with more than one hose–in some cases, up to three! This grants greater efficiency–and you will be able to finish the job twice or maybe even thrice as fast.

The Different Types Of Commercial Pressure Washers

A pressure washer can use either hot or cold water to clean and can be powered by either gasoline or electricity. Moreover, pressure washers have different setup types, including mountable, stationary, and trailers. Keep reading to learn which type is right for your needs.

Hot vs cold

cold water pressure washer is used for general cleaning jobs. You can easily blast away dirt, grime, and mildew from most types of surfaces with cold water. It is also the best option for temperature-sensitive surfaces, such as wood and plastic.

However, cold water is not enough to cut through oil and grease. This is where hot water pressure washers come in. These industrial-strength machines are able to tear oil apart at the molecular level. And since the heat eliminates any spill, cleaning is fast and efficient.

Plus, hot water pressure washers are more effective against extremely tough stains, such as deep-seated dirt, age-old mildew, and decades’ worth of grime. In general, anything that a cold water pressure washer can do–a hot water pressure washer can do better.

Gas vs Electric

Electric pressure washers are common choices for household cleaning. They are lightweight and easy to use. This makes them great for general cleaning jobs like washing the fence or removing grime from house siding. They also require little maintenance. You will only need to clean these a few times a year, lubricate key parts, and replace some O-rings in the connections when they get too worn.

A gas-powered pressure washer, on the other hand, is more expensive than its electric counterpart. With the higher price comes more power and better durability, of course. A gas pressure washer can go up to 4,200 psi, whereas most electric models can only go as high as 2,000 psi. On top of that, a gas-powered pressure washer is built to withstand extreme wear and tear; with proper care, you can expect your unit to last for more than ten years!

Mountable vs Stationary vs Trailers

First up, we have mountable pressure washers. This type of pressure washer is hung on a wall to serve specific areas. For example, you can use a mountable pressure washer in the rinsing area of a car wash, or perhaps the wet area in a butchery. There are also mountable pressure washers that you can attach to an ATV – allowing you to take your cleaning on the go.

Stationary pressure washers, on the other hand, are typically situated in one spot only. Usually, you will see this type of washer in wash bays to clean equipment and vehicles. Since these washers are compact, they can also be transferred from one area to another to clean different parts of a facility–albeit with some effort.

Lastly, we have trailers. If you do not have a water source in the area that you need to clean, a commercial pressure washer trailer allows you to have an onboard water source alongside your unit. That said, having a mobile pressure washer can open a whole new world of possibilities for your business. Whether you need to clean a construction site that has no running water or power wash in the middle of the road, a pressure washer trailer will let you take your unit anywhere.

Our Criteria For Choosing The Best Commercial Pressure Washer

Now that you have a detailed understanding of the different types of commercial power washers, let’s talk about what separates the best from the rest. In order to choose the best of the best commercial pressure washers out of a sea of options, we have to take a few factors into consideration, including:

PSI, GPM, and CU

These three ratings determine how effectively a particular model can clean. The psi (pounds per square inch) refers to the amount of pressure that your unit produces. The higher the psi, the more effective your pressure washer will be at cleaning.

Industrial-grade pressure washers can go up to 7,000 psi, but for most industrial applications, you likely won’t need more than 4,000 psi. We have an article on how much pressure washer psi you need if you want to learn more.

Next is GPM (gallons per minute), which determines the amount of water that your pressure washer pumps out per minute. Just like psi, the higher the GPM is, the more capable your pressure washer will be.

Finally, we also have to consider the CU (cleaning units) rating. CU is the product of multiplying PSI by GPM. This spec will help you see how the PSI and GPM impact the effectiveness of your pressure washer while in use. In other words, the CU will give you an idea of how much cleaning power a particular unit has.

All of these specs add up to how powerful your model is. And as you can probably imagine, the best commercial pressure washer is one that boasts impressive power ratings.


Unless you only plan to place your pressure washer in one spot forever, portability is another important factor to consider. A portable pressure washer is a must if your business involves cleaning on different sites or cleaning wide spaces. If you choose a unit that has limited portability, you also limit the type of jobs you can do.

That said, most of the units we’ve chosen for this list are highly portable, coming with movable frames and wheels to allow for easy transport.


Commercial power washers don’t come cheap. So, you obviously want to ensure you get the most out of your investment with a long, useful life of the pressure washer. Unfortunately, not all are made equal; some are tough as nails, while some may give out after only a few years.

Luckily for you, our list only contains the most durable models available on the market. We know how important it is for an investment to pay off, and that’s why we’ve selected models that are built to last.
