A commercial pressure washer is a serious upgrade for any home service business. These machines can handle tougher jobs, stubborn grease, and even oil. With more power and more durability, a commercial-grade pressure washer gives you the upper hand on any cleaning project. 

There is a wide range of commercial pressure washers on the market. Prices can range anywhere from around $500 to upwards of $10,000. Choosing the right model is a big decision and investment. 

So, where do you start? This article will walk you through the process of choosing a commercial-grade pressure washer. We’ll explore what you should be looking for, compare some of the top models, and give you some pro tips to help you choose the right model.

Why You Need a Commercial-Grade Pressure Washer 

Commercial pressure washers are designed for high-powered cleaning. They pressurize water through either a gasoline or electric-powered pump. The pressurized water can be used to clean roofs, windows, floors, equipment, and any hard surface. They’re particularly helpful with cleaning oils, tough stains, and hard to reach places.  

A commercial model is built to handle higher-volume and more frequent use than a residential model. They are typically larger, more powerful, and longer lasting. A commercial pressure washer has an average of about 2,000 to 4,000 PSI, which gives you significantly more power than a home model. The average home model has a range of 1,300 to 2,000 PSI. 

They are built with durable, lasting materials that withstand the battering of professional jobs. Commercial-grade equipment is designed to perform better and handle extreme conditions. Many models are housed in steel caging and are manufactured for on-the-job use.  

These tools are useful for industrial projects and busy workdays. A commercial pressure washer could benefit contractors, window cleaners, plumbers, roofers, and anything in between. They’re a versatile tool that helps ease the strain of the job and can speed projects up.

Factors to Keep in Mind When Selecting a Commercial Pressure Washer 

It may seem as easy as picking a decently priced pressure washer and moving on. However, there are a lot of different factors and components to these machines that are important to consider.  

You want to be sure that the model you choose has the capabilities to handle the job. Let’s look at some of the things to consider when searching for the right model: 

Pressure output and water flow rate 

The pressure output (PSI) and water flow rate (GPM) are the two units of measurement that pressure washers use. The psi will determine how powerful the water stream is, while the GPM measures the volume of water flowing.  

GPM is the water flow rate measured in gallons per square inch. PSI is the water pressure measured in pounds per square inch. For most commercial operations, a psi of 3,000 to 5,000 is recommended. And most commercial units will have a range of 2.5 to 10 GPM

A higher GPM might be more effective when cleaning larger surface areas.  A higher PSI is more effective for cleaning stubborn spots and buildup. The key is to find a model that has the right balance between these to suit the needs of your business.  

Hot vs. cold water cleaning 

Hot water and cold water can both get the job done with a pressure washer. Hot water, as a general rule, is what most of us use to clean. But the cost and job considerations should factor in.  

Cold water machines are more suited for cleaning dirt and mildew, stripping, and removing paint. They’re often used for cleaning surfaces like driveways, porches, and sidewalks.  

A hot water unit might be worth the investment if you’re handling tougher messes. Hot water is better for oil and grease and sanitizing surfaces for a deeper clean.  

Power source (electric or gas) 

Commercial pressure washers are either gas-powered or electric.  Gas-powered models are more powerful than electric washers, with a higher PSI on average. They’re often more durable and have a longer life.  

Electric models tend to be more affordable, easier to use, and require less maintenance. Electric models are also far quieter than gas models. However, they have less mobility due to needing to be plugged in.  

Portability and maneuverability 

Various models offer different mounting and transportation options. Depending on the job, you may need more portability. A portable machine is usually on a set of wheels or trailer and can be moved easily from place to place. There are also portable machines with a roll cage, which offers more protection for the unit.  

There are many mountable models as well. Some commercial units can be mounted on a wall or a work truck. A wall mount works best if you have a facility that the machine will be used in, where any projects will take place. Otherwise, a truck or skid mount is a great option for a company vehicle that will be on-site.

Key Features Essential in Commercial Pressure Washers 

Like any equipment, not every model is made equally. Getting the job done and getting the job done well can be two different things. You want to make sure that your business is providing the highest quality work. So, you’ll want your equipment to be able to keep up. 

Here’s some of the features to look out for and compare on various pressure washers: 

Pump quality and durability 

The pump is the powerhouse of your pressure washer. When choosing a model, you want to consider what pump type the unit has. Most commercial-grade pressure washers have either axial cam pumps or triplex plunger pumps.  

An axial cam pump is a direct drive. This means that the pump is directly spinning the cylinders that pressurize the water. They have a shorter lifespan than a triplex pump, but they can provide a lot of power.  

A triplex pump powers a crankshaft that moves plunger rods to pressurize the water. It tends to have more power and longevity than an axial cam pump.  

Nozzle options for versatility 

Nozzle options allow for different levels of cleaning. They also can be used for more specific projects. Common nozzle types are quick-connect nozzles, rotary nozzles, and sewer jet nozzles.  

Quick-connect nozzles have 5 different degrees of cleaning capabilities based on the flow and pressure of the water. These are color-coded and easy to use.  

Rotary nozzles spin in a small diameter at high speeds, giving them the nickname “turbo nozzle.”  These nozzles are great for paint removal.  

Sewer jet nozzles are used to clear out drains and pipes. They can be used with cold or hot water pressure washers.  

Detergent injection system 

A detergent injection system enables you to spray detergents or other chemicals using your pressure washer. A downstream injection system can be inserted on the pressure side of the pump, which protects any other components from being damaged by any chemicals.  

This is a useful tool for many home service providers, and very helpful for keeping company equipment clean. 

Pressure control mechanisms 

A pressure washer with variable psi can be handy. This allows you to adjust the psi for certain projects regardless of your nozzle. Since most commercial pressure washers are pretty powerful, this is a useful feature. It allows you to do various projects without risking any damage.  

Heating and cooling abilities 

Like any machine, pressure washers run the risk of overheating. This is more of a risk with gas-powered washers, but it happens with electric models too. Many pressure washers have a thermo-release valve to help prevent overheating. The valve will open to let hot water out and bring cold water in, effectively cooling the pump.  

Commercial Pressure Washer Accessories and Add-Ons 

Many commercial-grade pressure washers offer accessories or add-on equipment. Depending on your business and industry, this might be an important consideration.  

Pressure washer surface cleaner 

This attachment creates a flat, even spray to help with cleaning. These attachments connect directly to your wand and can be moved over flat surfaces. They’re a great option for larger surface areas that need a swift, even clean.  

On average, these can range anywhere from around $200 to over $1000.  

Pressure washer guns and lances 

Pressure washer guns are effective for cleaning hard-to-reach areas. They work great for gutters, wheel wells, undercarriages, and super deep cleaning. A lance can help extend your reach.  

You can find most of these accessories for under $100.  

Pressure washer hose reel and carts 

A pressure washer hose reel allows for organization and access to various hoses. They can be portable and move with you as you work, or they can be mounted and motorized. A hose reel helps prevent damage to your equipment.  

A hose reel can cost anywhere from around $100 to around $500

It also features adjustable pressure, so that you can control your psi. At $1,399, it’s more reasonably priced than other options out there.  

Cons: The machine can last for about 5 hours, which is a little less than other models offer. It also has an aluminum frame, which can be more easily dented.   

Best electric: Pressure-Pro Professional Pressure Washer 

Pros: This unit is much quieter than a gas-powered model and can be used in unventilated areas. It has 3 GPM and 3000 PSI, which is comparable with most gas models. The model also has an automatic start and stop, meaning it will only be running when in use.  

Cons: A 12-foot cord limits your radius for cleaning. This means you’ll have to be relatively near a power source to use your pressure washer. The cost is also higher than other options, coming in at over $3,000.

Pros: This unit is durable, functional, and versatile. The machine has 4000 PSI and 4 GPM.

With adjustable water pressure and raving reviews, this unit is a great choice for any professional who needs a reliable unit.  

Cons: The unit costs $2,132.99, which can be a lot if you’re running a small business. It is also built for daily, heavy usage. So, this may not be the right investment if you only need a pressure washer from time to time.

Cons: While it will still get the job done, this only has 2,000 PSI and 4.0 GPM. That’s on the lower side of psi for commercial pressure washers. It also costs about $2,800, which is a lot of money for a lower PSI.  

Best bang for your buck: Westinghouse Gas Pressure Washer 3800 psi 

Pros: This cold-water pressure washer boasts 3800 PSI, 3.6 GPM, and a triplex pump. For only $729, that’s a steal. For businesses that need something powerful and easy on the bank, this is a great option.

Top Takeaway Tips for Choosing a Commercial Pressure Washer 

When choosing a commercial pressure washer, there are a lot of variables to consider. It can be easy to get caught up in the nicest, flashiest models, but how do you really narrow down what your business needs?  

It’s important to prioritize based on your company’s needs, budget, and your own research. Here’s where we recommend starting when choosing a model: 

Evaluate your budget 

As much as we’d all like to be able to afford a $16,000 pressure washer, that may be out of the budget for a lot of business owners. Figure out what your business can realistically afford before getting too deep into shopping around.  

Going into a big purchase with an organized budget will help you narrow down your search. It also will ensure that you’re not breaking the bank or stretching yourself too thin. 

Prioritize your needs 

Different pressure washers offer various features and components. Depending on what your business does, you may not need every top-dollar feature. Or you may need all of them and then some.  

What will you be using your pressure washer for? If it’s just to keep your company’s equipment clean, you likely won’t need the longest hose and maybe could do without a hot water system. Knowing what you need and don’t need can help you choose a model and save some money.  

Read reviews and watch videos 

Customer reviews are your secret weapon when choosing a commercial pressure washer. There are many reviews, forums, and videos out there that explore the various features and overall quality of each product. If you have your eye on a certain model, do some research and see what people have said about it.  

YouTube videos can be really helpful for comparisons and observing each model in action. There are many high-quality videos out there that will break down models and show you what they can do.
