Picture this: You’ve decided it’s finally time to clean your home’s exterior thoroughly. You’ve heard about power washing and pressure washing, but you’re not quite sure which one is the best fit for your needs. Standing in front of your house, you wonder, “What is the difference between power washing and pressure washing?” 

Power washing uses heated water along with high pressure, perfect for hard stains like grease. Pressure washing uses cold water with high pressure, suitable for many surfaces without causing damage. 

Let’s learn more about these methods and how they can help clean your home.

What is the Difference Between Power Washing and Pressure Washing? 

Let’s check out the table below showcasing the differences between power and pressure washing all in one setting.

Key Differences Power Washing Pressure Washing

Water Pressure Typically, higher water pressure, up to 4000 PSI Lower water pressure, below 4000 PSI
Cleaning Power More effective at removing stubborn dirt and grime May require more passes to achieve the same level of cleaning

What is Power Washing? 

Power washing is when we use hot, high-pressure water to clean outside surfaces. Some people call the machines used for power washing “hot water pressure washers.” 

Power washing is great for big jobs with tough dirt and grease. The hot water helps get rid of grease and dirt by using both force and heat, kind of like when we wash dishes.

How Does Power Washing Work? 

So, what is a power washer? Power washers are such machines that use strong, pressurized water to clean dirt. But they also use hot water because it’s good at dissolving grease and other stuff. The high pressure and heat together make power washers able to clean almost anything. 

But be careful – they can be too rough and damage some surfaces, like wood or brick. So, it’s best to use power washing for things like long driveways.


Pros of Power Washing

Let’s check out the advantages of power washing:

  • Heat: Hot water cleans better because it’s like a cleaner itself. When water gets really hot, its molecules bounce around a lot, which helps to break down tough things like grease and mold. This makes power washing the top choice for hard stains like grease and oil.
  • Pressure: Power washers usually have stronger water pressure, typically ranging from 2000 to 4000 pounds per square inch (Psi) on average. They also pump out more water per minute (GPM) than pressure washers. In simple terms, this means they push more water with more force onto the surface you’re cleaning.
  • Great for Weeds: Power washing is great for getting rid of weeds, moss, and algae on driveways and other surfaces. The hot water kills plants and stops them from growing back easily.
  • Great for Large, Commercial Jobs: Power washers are perfect for big cleaning jobs, like commercial buildings or large areas. They save time and make cleaning faster and easier.

Cons of Power Washing

As we said earlier, power washing is great for big jobs, especially for businesses. These strong machines can clean large areas fast and get rid of dirt easily. But, there are some drawbacks too.

  • Cost: Power washers are usually more expensive than pressure washers because they need an extra heating part. This can make them cost thousands more.
  • Less Flexible: Power washers are good for big jobs that need a lot of power. But they can be too strong for smaller jobs at home. Pressure washers are better because they can clean a wider variety of surfaces. 
  • Too Strong: Power washers can clean really well because of the heat. But sometimes, they can be too strong and damage softer materials. They’re best for hard surfaces like cement or concrete.

What is Power Washing Used For?

Power washing is great for cleaning big areas outside that are made of tough materials. For example, if your concrete driveway is dirty with hard-to-remove dirt, grease, and weeds, a power washer is perfect.

They’re also good for cleaning in commercial places like restaurants or auto shops. The hot water can easily clean up grease and oil.

Power washing is also handy for getting rid of tough stuff like black mold, chewing gum, ink, or spray paint.

What is Pressure Washing? 

Pressure washing involves using strong, cold water under high pressure to remove dirt and debris. While it’s not as effective for getting rid of moss, mold, and oil, it’s still powerful enough to clean driveways and home exteriors.

How Does Pressure Washing Work?

Pressure washers use strong water pressure to clean surfaces. The water comes out fast and pushes away dirt, dust, mud, and other stuff stuck on surfaces. Unlike power washing, pressure washing doesn’t use hot water, so it won’t get rid of grease and grime as well. But for most jobs, like cleaning your driveway or house, a pressure washer is good enough.

On the market, you can find many different pressure washers. Some of them have nozzles that let you control how strong the water comes out. With these attachments, you can use pressure washers on lots of different materials and surfaces.

Pros of Pressure Washing

Let’s check out the advantages of pressure wash cleaning:


Pressure washers are more versatile than power washers. They have different pressure settings, so you can use them on many surfaces without causing damage.

One reason people like pressure washing is because it comes with different nozzles. These nozzles change how the water sprays out. For instance, a nozzle with 0 degrees sprays water straight, while one with 25 degrees covers more area.

Because of this, pressure washers are great for various jobs, like cleaning cars, wooden decks, and siding.

Suitable For Many Jobs

Pressure washers have many choices available. You can pick from different GPM and PSI numbers to make sure you have the right amount of force for what you’re doing.

They’re good at cleaning lots of different surfaces, like siding, decks, bikes, and even cars if you set them up rightly.

More Options

There are different kinds of pressure washers, but the main ones are gas and electric.

  • Gas-powered ones are stronger and better for tough jobs.
  • Electric ones are better for household use. They usually plug into the main power supply, but you can also find some that run on batteries. These are easy to move around but not as powerful.


Pressure washers are cheaper than power washers for a few reasons.

  • First, they don’t have a hot water feature. 
  • Second, they’re designed for different tasks. Power washers are more for big businesses, while pressure washers are better for smaller jobs or at home.

Since pressure washers are mostly for homes, they come at different prices. So, if you’re on a budget, you can find one that fits your needs.


As we mentioned earlier, pressure washers are made for regular people to use at home. So, they’re easy to understand and don’t need a lot of technical knowledge to use.

But remember, they’re still powerful tools, so it’s essential to be careful. If you get one, make sure to read the instructions carefully to use it safely.

Cons of Pressure Washing

Let’s check out the disadvantages of pressure washing:

Surface Damage

Some folks think they won’t harm surfaces using a pressure washer since it’s not as strong as a power washer. But it’s not that easy.

Pressure washers can still be mighty. For instance, gas pressure washers can reach up to 4000 Psi. That much force can easily damage various surfaces. So, before you begin cleaning, it’s smart to research which pressure is safe for different materials.

Risk of Misuse

Pressure washers are mainly used in homes, so people who aren’t familiar with how to use them might hurt themselves while using them.

Even though they’re not as strong as industrial ones, a high PSI with a 0-degree nozzle can still be very forceful. That’s why it’s important to be cautious when using them at home, as the pressure could cause harm to adults and pets.

Cordless Pressure Washers

Cordless pressure washers have some great benefits. They’re easy to carry around, and you can move around without being held back by cords or gas tanks.

However, these machines usually have less than 1000 PSI. That’s good for gentle surfaces, but it might not be strong enough for tough cleaning or stubborn dirt.

What is Pressure Washing Used For?

Pressure washing is great for getting rid of dust, dirt, mud, and other stuff from lots of outdoor surfaces.

It works well on walls, decks, driveways, patios, and windows. Since it uses cold water, you don’t have to worry about heat causing damage.

It’s perfect for getting rid of surface dirt, stains on concrete, moss, algae, and mold.

Compared to regular cleaning, pressure washing gets deep into areas. Just be careful not to use too much pressure, or you might damage paint or softer materials.
