Power washing and pressure washing are two different processes that can be used to clean a home or business. Understanding the process of each is important because it will dictate how you go about cleaning your residential or commercial building in the future. In this blog post, we’ll take a look at power washing and pressure washing so that you know which one is best for your needs.

Just as important as knowing what type of process to use when cleaning your home or business is understanding how they work. So let’s dive into power washers vs. pressure washers!

Pressure Washing and Power Washing Differences

It’s easy to confuse power washing and pressure washing. Both processes clean your home or business, but they are very different. This post will discuss the difference between these two methods of cleaning a surface and why you might want one over another for your specific needs. We’ll also go through how each process works!

First, let’s address the difference between power washing and pressure washing. Power washing is a process that uses water to remove dirt from surfaces. Pressure washing is also a process that uses water to remove dirt, but it does so with more force and higher temperatures than power washers.

Pressure Washing

Pressure washing is a cleaning technique that uses pressurized water to remove dirt and stains from surfaces. Pressure washing is a process that cleans surfaces with water pressure and high-pressured air. This cleaning method restores surfaces to their original condition, removing dirt, mold, and other debris from the surface. It’s important to note that it does not remove stains or grime from inside the material – only on the surface.

It uses a high-pressure water jet to remove contaminants from hard surfaces like rocks, sidewalks, concrete driveways, and stairs. You can use this method on any outdoor or indoor surface that doesn’t absorb water, such as metals, vinyl siding, brick pavers, asphalt shingles, or metal roofing materials. This form of washing will not damage these surfaces, but it’s not always the best option for every surface. For example, you should never use a pressure washer on delicate surfaces like marble because of the risk of damage caused by high-pressure water.

Pressure washing is often more effective than other methods such as soap and scrubbing at removing stubborn dirt and grime with less effort. 

Pressure Washing Pros:

  • This is great for removing dirt and stains from concrete, brick, metal siding, masonry tile floors, or other heavy-duty jobs. 
  • It is suitable for removing tough stains, such as oil and grease, from the surface.
  • This type of pressure washer uses a water nozzle with high pressure to dislodge dirt and grime that may be embedded on any surface in your home or business.

Pressure Washing Cons:

  • It can cause discoloration of natural stone surfaces because it relies mainly on the power of high-powered water jets. 
  • It can cause damage to the surface, especially if you use too much pressure or a chemical that is not appropriate for your material. For example, concrete needs more gentle cleaning than aluminum siding.
  • Another con is that pressure washers are often loud, which may disturb neighbors living next door if they’re home during your time window for cleaning their property.

Power Washing

Power washing machines are usually used for lighter tasks like cleaning windows, patio furniture, and siding on your house, but these days, people find more and more reasons to use them as well, such as cars, decks, sidewalks, and even your lawn. Power washing is a great way to clean things that are hard to scrub with soap and water, like cars, for example. There are many different types of power washers, including gas-powered machines that make quick work of tough jobs at an affordable price tag.

Pressure washers work by generating pressure water that can remove dirt, mold, or mildew from these areas without damaging them in the process. It doesn’t require as much pressure because it relies mainly on water flow rather than pressure to remove dirt and debris. The most critical component of the power wash system is detergents that emulsify particles to create foam that loosens the dirt so the water flow can more easily remove them.

Power Washing Pros:

  • It’s easy on windows because it doesn’t use the same strong chemicals as pressure washing does, so there isn’t any risk of them getting scratched.
  • The power washers can be used in many different ways, making them versatile from window cleaning, decking work, house washing, driveway paving, etcetera. 
  • Quick and easy – most people prefer it because of how quickly and effectively dirt disappears from porches and sidewalks with minimal disruption. 
  • The function of this technique is not just limited to cleaning but also includes deodorizing, which means it eliminates smells like pet urine odor, cooking odors, cigarette smoke smell, etc. by using fragrance discs available at hardware stores while mixing hot soapy water with cold water via proportioning valve attached to the water hose.

Power Washing Cons:

  • It takes longer with using the power washers (usually) to get the job done, but this doesn’t matter if you have someone helping who can move quickly or use both machines at once.
  • Can remove good bacteria when using an aggressive detergent (this is usually okay, but it’s something worth noting).
  • It may also be quite disruptive to plants in outdoor landscaping areas and lawns near soapy water.


It’s understandable if there is a little bit of confusion about the difference between pressure washing and power washing. They are similar in some ways, but they have some key differences that you should know before deciding which one to use for your home or business.
