What Are Professional Pressure Washers Used For?
A pressure washer is a machine that is made to utilize the power of pressurized water and aim it towards cleaning. If you are having a hard time imagining the system, just think of a standard backyard hose, but immensely more powerful. Now, finding a correct usage for a powerful machine such as this should be easy enough, especially when we are talking about commercial grade pressure washer models.
The distinction between a regular residential model and a commercial pressure washer is in the performance and endurance. Commercial units are made to handle bigger loads, and the intricate machinery parts come with longer-lasting materials. Now, we are not saying that residential models do not perform well, no, we just want to point out that commercial grade power washers can withstand longer cleaning sessions and can tackle harder stains in your backyard.
Even if you are not a commercial shop owner, and you like to have a tidy backyard, you might consider getting a commercial unit for its water consumption, power, and longevity. But, what can you clean, and what kind of stains and dirt can you defeat using such a device?
1. Backyard Cleaning
Of course, the very first thing everyone thinks about when a pressure washer is mentioned is their backyard, or front yard, depending on your household. The situation in which a commercial pressure washer excels at is spring cleaning. Just imagine having the power to remove all that residual dirt from last years’ rains and snows.
Besides cleaning concrete and fences, you will be able to wash all the metalwork around the house. Gullies, gutters, garage doors and many more are fair game if you want to get that old, same-as-new shine out.
2. Washing Boats and Cars
Ah yes, one of the most frequently asked questions regarding commercial pressure washers: Will I be able to pressure clean my boat with this? Well, as it turns out, pressure washing is the best way to go, especially when we are talking about boats.
Different materials are made to endure different elements and weather conditions, and that is why an adjustable pressure washer will be the best assistant in cleaning them. Boats and cars are not prone to water damages, and if you adjust the pressure to match the surface, nothing can stop you.
3. Patio and Yard Furniture Cleaning
If you have a larger backyard, especially one full of grass and soil, you are aware of the dirt that sticks to the furniture. With a pressure washer, you will be able to clean it very fast, and with utmost efficiency. Cleaning patio furniture is one of the main reasons why people decide to get a powerful pressure washer in the first place. If left unattended and dirty, any kind of outdoor furniture will suffer irreparable damages, so think ahead!
4. Washing Decks, Stables and all Sorts of Outdoor Floors
Outdoor floor surfaces can be a hassle to clean. These surfaces are usually much larger than the surfaces we have inside, and no one wants to spend all day every day holding the hose and a steel brush. Pressure washers are designed to tackle this kind of problem with ease. Just make sure to test out the strength on a smaller surface and adjust the pressure accordingly.
You can check our pressure washer surface cleaner reviews for more information.
5. Grills and other Greasy Surfaces
Lastly, having a pressure washer will help you degrease the old grill and return it to its former glory. The best thing is: you will only need water to get the job done. Grills, griddles, and fireplaces can all be washed with pressurized water, due to material endurance and resilience. You can also pressure wash greasy tools and old traffic signs.
Hot vs. Cold Water Commercial Washers
This debate will never be settled even among the professionals and engineers, so we will try to showcase both perspectives, for transparency’s sake. Both hot and cold-water pressure washers have their ups and downs, and there is no clear answer on which is better. It all depends on your demands, and the surfaces and items you will be cleaning.
Fewer pressure washer models use hot water for the whole process. The rule of thumb is that hot-water washers always come with a heftier price, because the entire machinery system is more delicate, and a bit different to a degree. The main advantage of a pressure washer that uses hot water is the ability to tackle oil and grease with higher efficiency. You are probably aware of the fact that fat doesn’t quite go well with cold water.
So, instead of adding a gallon of soap, use hot water instead. If you intend to clean heavily-greased surfaces (e.g., car workshops, outdoor grills), hot water will be an ally. You might still need soaping adjustments, but the amount of water and soap you will need will significantly reduce.
On the other hand, pressure washers that use cold water can usually operate on higher pressure modes. Higher pressure often translates to larger-scale cleaning projects, and a harder punch directed towards stains. Although it will not clean oil stains as well as its hot-water counterpart, cold water pressure washers still have a wide range of utility, but in the less sophisticated areas.
A cold-water pressure washer can make up for the lack of impact on oily stains by employing cleaning agents and chemicals, though it is not recommended to do that often. But, when it comes to dirt and grime, a cold-water model will do the job.
However, even though they are somewhat equal, there is a task that only a hot-water pressure washer can do, which makes it stand out. We are talking, of course, about none other than chewing gum. If you ever tried to clean chewing gum out of the driveway, you know that cold water will only make it harder and stick even stronger. Hot water, on the other hand, makes the gum mushier and it gets it to detach from the concrete surface in a matter of seconds.
So, to summarize – cold water for dust, grime, dirt, and large-scale projects, and warm water for oils, grease stains, bubble gum, and more delicate pressure washing.
Gas or Electric Commercial Pressure Washers?
As with many things, when it comes to modern machinery, choosing the right power source is as important as the rest of the specifications. When commercial pressure washers are the topic of the hour, we must make a distinction between two main groups: gas and electric. There is no clear answer on which is better because the truth is that we would be comparing apples and oranges to an extent.
Both fuel sources bring certain types of benefits. The fuel source will change the overall usage style of the pressure washer, as well as the looks and general feel. Let’s see what kind of advantages and disadvantages each type brings, and how you can decide which will fit your personal requirements in the best possible way.
1. Gas-powered Commercial Pressure Washers
If you are a fan of old-school machinery and like to have appliances that can provide an extra-powerful kick, gas is the way to go. Gas engines are simply more potent for the same investment, compared to their electric counterparts. So, what are the main advantages and disadvantages of gas commercial pressure washers?
- No electric cord
Gas engines have everything they need right there with you. Portability is the main benefit from the absence of electrical cables, and if you have a larger surface to clean, you will find this feature convenient above all.
- More power
Even though we are living in the era of ever-evolving tech, when it comes to raw power, nothing beats a gas engine. If you decide to go down this path, make sure to test how sensitive are the surfaces you want to clean. More power can sometimes mean irreversible damage.
- Exhaust, noise, and maintenance
These disadvantages are not that big of a deal in the long run, but they are not to be undermined as well. The two things you will have to deal with are noise and exhaust gases. Engines tend to be much louder than electric motors, and exhaust gases will make working indoors very hard or not even possible. Lastly, maintaining an engine (oil, fresh gasoline, and gasoline stabilizers) is not complicated, but, if you want to have a trustworthy pressure washer, you will have to do regular maintenance.
2. Electric Commercial Pressure Washers
Some people prefer electric motors to gas engines, for multiple reasons. The best electric pressure washer models are gaining in popularity thanks to technological advancements that prefer eco-friendlier fuel sources. So, what should you expect from a professional electric pressure washer?
- Less noise and no exhaust
Electric motors, even though they are somewhat weaker than gas engines, generally make less noise. Some professional kitchens also managed to use electric commercial pressure washers inside, due to the convenience of it all. On top of everything, because no fuel is being burned on the site, there are no exhaust gases for you to worry about.
- Low maintenance requirement
Engines are known to be somewhat needy when they are used often, but electric motors require little to no hassle. The majority is oil-free, and all you will have to worry about is not to “overwork” it, which rarely happens anyway.
- An electrical outlet is a must
The major downside for most is that you will have to have an outlet wherever you want to clean. Manufacturers are building in extra-long cords, yes, but that doesn’t diminish the need for a socket.
Commercial Pressure Washer Buying Guide
Now we have seen the basics of commercial pressure washers. We went through their strengths when it comes to the tasks they can tackle, and we talked about two major fuel source differences. But it is time to go through the intricacies of parts, features, and specifications you should know before you decide which model is the right one for the job. In today’s market, there are a lot of different models, and each and every one of them brings something different to the table, so pay attention and make a checklist of your own. Let’s dive in!
1. Overall Strength and Cleaning Power
A common mistake people make while choosing the ideal model is chasing those high numbers. Don’t take this the wrong way, we also think that more power is a great feature, but there is more to this than meets the eye.
Pressure washer power can be measured by using several methods. There’s engine/motor horsepower rating, there are wattage and amperage, and finally, there are the three (or two depends on whom you ask) most important numbers you should look out for: GPM (gallons per minute), PSI (pounds per square inch), and the combination of the two – CP (cleaning power) which you get when you multiply GPM with PSI.
CP can vary from a few thousand to tens of thousands, but what does it all mean? With a reliable pressure washer, you will be able to remove ten-year-old stains out of your driveway, but if the washer has no proper pressure adjustment module, you will most likely destroy wooden surfaces. So, if you do not have the need for cleaning hardcore stains, you might want to consider taking the middle path when it comes to power. And if you are dealing with grease and dirt on hard surfaces all the time, the more powerful the washer, the better.
Even though every commercial pressure washer comes with a hose, which is usually 20+ feet long, you should probably consider the overall weight of the unit. Commercial-grade pressure washers may vary in weight, and we are talking about a 40 to 300+ pounds per model variation. So, before you decide on the model you want to buy, factor in the weight, depending on the size of the surface and items you want to clean most often. If you own a large backyard that needs to be cleaned now and then, a super-heavy unit will just be a hassle to use. You get the idea.
However, the mere weight of the unit is the only factor that determines the portability of the pressure washer. The next thing you should look for is a transport system. Usually, a pressure washer will have some form of a 2 or a 4-wheel system installed, so you do not have to carry it around but haul it instead. These wheels will almost always be a “never flat” sturdy type, but make sure to check twice.
Having a mighty and powerful pressure washer is great, but you must think about storing it also. These machines are made to last, yes, but if left unattended, the elements and bad weather will have the best of them. Though commercial pressure washers are more powerful and heftier than their residential counterparts, there are some differences that you should take into account while deciding which model you wish to buy.

If the manufacturer decided to put heavy-duty elements into the pressure washer, it would most certainly be supported by a steel frame. This frame serves as support, both for carrying and for protection of the engine or motor. Large frames take up more space but will often be shaped to fit tight spaces.
3.2 Frame Orientation
The two most common build orientations are, of course, vertical and horizontal. The upright pressure washers are easier to store, especially if you have extra space in a garage-like room. The vertically oriented models are somewhat rectangular and will require more floor space, though they can usually be placed underneath a desk or under a workstation.
4. Versatility and Additional Features
Finally, subtle differences enter the spotlight. As you might have concluded from the previous sections, each model differs and excels at different tasks. We are not saying that a single model corresponds to a unique type of cleaning, but the truth is there isn’t a model out there that has it all.
After you have factored in the fuel type, size, build, power and the rest of the basics, the last thing to care about is the little features that make specific models specialized for certain jobs, to some degree. Let’s see what you can expect.
4.1 Auto shut-off function
The bread and butter of super-busy people. What the automatic shut-off feature does is keeping the pressure washer from overheating, or clogging, by turning it off, no matter where you are at that moment. This feature is primarily made as a safety addition, but it will also save you soap and gas or electricity.
4.2 Adjustable pressure gauges
This feature is designed for people that want to wash surfaces made of different materials, which can usually withstand different pressures. Sensitive floors and patio furniture can easily be destroyed by a full blast of a pressure washer.
4.3 Spray wands
In the convenience sector, we have long spray wands that will help you reach corners and high places. Almost every model will have a spray wand, but, if you are looking for more control, get a rod that has pressure control conveniently placed on it. This way, you do not need to go back to the pressure washer to change the exerted pressure.
4.4 Spray nozzles
Another great way to increase the versatility of a pressure washer is to have more interchangeable quick-connect spray nozzles. When it comes to the classic pack, there are:
- 0° nozzle – for highest pressure
- 15° nozzle – for grills and resilient materials
- 25° nozzle – for wooden surfaces and lighter materials
- 40° nozzle – for watering plants, and light-duty work around the garden
- Soap nozzle – specially designed for the usage of soap
4.5 Soap tank
If you intend on cleaning a lot of sturdy and greasy stains, you will probably want to invest in a model that has an attached soap tank. Cleaning agents and special soap are easily distributed and evenly sprayed using the power of the pressure washer. The general rule of thumb is – the larger the soap, the better and longer you will be able to wash uninterruptedly.
Safety Tips for Commercial Pressure Washing
“A double-check is a key to a long life” – this is a common saying among people who work with powerful machines, or at least a variation of the saying. There is a big reason for this. Pressure washers, primarily commercial-grade models, can be extremely dangerous due to their power. Besides the raw pressure, there are things before the cleaning process that you should take care of.
So, why don’t we go through some of the general guidelines, just to be sure? It’s better to be safe than sorry. Always.
1. Check the Machine Before Starting
No matter if you have a gas unit or an electric model, make sure to check the couplers, pipes and hoses, and the state of the engine before you begin. If you get used to this process, it will take no longer than 5 minutes, and a little safety check can go a long way.
If any part of the pipeage is damaged, you can quickly replace it and start washing.
2. Protective Gear
Safety goggles and heavy-duty gloves are always welcome while pressure washing with a commercial-grade model. One wrong slip can cause an injury to you, or damage something around you. Now, we are not saying that you need to be protected from head to toes, but keeping your vital parts should be paramount.
3. Changing Settings
If you run out of fuel, or you need to change the nozzle extension, do not hesitate to turn off the pressure washer first.
Refueling while the engine is on can cause it to explode, or at least cause damages to the engine itself. Turn the engine off, wait for it to cool down for a moment or two, and then start the refueling process. A few minutes of waiting will not make a huge difference in your plans, but it will save you from potential harm and expensive damage.
And in the case of nozzle changing, never do it while the pressure washer is on, no matter if its a gasoline or an electric type – always turn it off first. Make sure the nozzle is firmly attached, and the coupler is undamaged. Only then can you return to washing. Oh, and do not forget to put the nozzle you are not using somewhere you will not lose it. Nozzles get lost easier than you think.
4. Always use both hands
People get carried around with the best pressure washer extension wands and often underestimate their power. Always hold it both hands, firmly, with one hand controlling the pressure trigger, and the other aiming at the dirt you want to wash off. The pressure generated and transported through the wand is so intense that it can cause a recoil, and if not held correctly, damages may occur.
FAQ About Commercial Pressure Washers
1. Can I use my commercial pressure washer indoors?
It depends on the washer. If we are talking about powerful gas-guzzling models, the answer is simple. You can’t. Gas pressure washers emit exhaust gases that contain carbon monoxide, which is highly poisonous. Always use gas pressure washers outdoors.
On the other hand, electric pressure washers can be used indoors, as long as you find a way to safely put it near the surface you want to wash. Just make sure it has some room around it for cooling reasons.
2. Can commercial pressure washers damage paint coating on metal and wooden surfaces?
Yes, they can, and they will if you do not handle them correctly. We cannot stress enough how powerful some commercial pressure washer models can be. But, do not be afraid because there is an easy solution to this. Firstly, set the pressure gauge to lowest, and test the stream on a smaller piece of surface you want to wash. After that, adjust the pressure, so it starts cleaning, but it doesn’t damage the surface. The key is patience. Once you get the hang of it, you will almost instinctively know what to do.
3. How do I store my gasoline-powered commercial pressure washer?
People make a common mistake of leaving the fuel and the oil inside the engine. As you very well know, fuel is organic, and it can go bad. If, after you decide to use the washer again, you turn it on and the engine sucks the stale fuel in, there will almost certainly be damages to the engine heads.
The safest bet is to drain both oil and fuel if you plan to store your pressure washer for a while. In the case of electric pressure washers, all you need to do is store it somewhere safe and dry.
