Power Washing VS. Pressure Washing: What is the Difference?

Power washing and pressure washing are effective cleaning methods used in building complexes and exteriors. However, there are significant differences between the two. From the type of surfaces they are used for to the techniques, let us carefully examine the attributes of power washing vs. pressure washing.

  • Water Temperature

Power washing relies on the cleaning properties of hot water to achieve the desired results. However, pressure washing uses water at an average temperature.

  • Equipment

The equipment used for power washing vs. pressure washing differs too. While the former relies on a power washer, the latter uses a hose.

  • Technique

Power washing targets dirt and dust deposits, grime, algae and other substances that adhere to outside walls. A power washer is used to direct hot water to the said substances, loosening their grip and ultimately, removing them altogether. The hot water also kills mold, bacteria and algae.

When it comes to pressure washing, a long hose is used to spray water on affected surfaces, at very high pressure. This hose is connected to a tank that creates the necessary pressure. And that can range between 1300 and 2800 psi. The hose comes with multiple nozzle options to target high pressure water at different types of surfaces and crevices.

  • Power Washing Vs. Pressure Washing: The Purpose

Pressure vs. power washing are both very effective cleaning methods. They help get rid of:

  • Mildew and mold
  • Weeds and algae
  • Gum from sidewalks

The commercial and residential pressure washing methods also help to:

  • Clean vinyl, aluminum or wood siding
  • Refresh your deck or patio
  • Clean gutters
  • Brighten your driveway or walkway
  • Get your house ready for sale

Usually, pressure washing is effective in cleaning public spaces like stadiums, parking garages and open air plazas. The method is also popular for cleaning exterior facades, cinemas and vehicles of all types.

On the other hand, power washing is majorly used for removing paint off of walls, cleaning fences and masonry, washing concrete and asphalt surfaces, etc.

How to Use A Pressure Washer and How Does A Power Washer Work?

When trying to understand how pressure vs. power washing differs, a closer understanding of the process can further clarify things.  If you are intrigued about doing it yourself before you cann in a professional, here are the fundamentals of how to use a pressure washer.

Pressure washers run a pump that pressurizes the water from a garden hose to 1,000 lbs. or more. The water is then thrust out through a spray wand. More the pressure, the tougher the cleaning jobs they can tackle. The process requires a constant supply of water.

When it comes to a power washers, they are particularly effective against caked deposits of oil, grime, greases and protein. So, a power washer works by increasing the water temperature to up to 311°F. Hot water weakens congealed oil and grease and significantly improves emulsification, making it very easy to remove. That is why this method is very popular for commercial pressure washing in the food industry.

How to Choose A Pressure Washer vis-a-vis Choosing A Power Washer

If you are planning to rent or buy a pressure or power washer, it would depend on the type of cleaning you aim for. Is it for home use or do you want one to clean an office space? Also, how experienced are you with handling a pressure or a power washer?

The first step is to determine which category of user you belong to before figuring out how to choose a pressure washer.These types of equipment are available in consumer, semi-pro and professional models. They differ in terms of PSI, GPM, cleaning units, water temperature control etc.

  • Consumer-grade washers are equipped with consumer-grade engines and pumps. While you can use them every day, they are also suitable for a weekly washing routine for cars and other vehicles.
  • Semi-pro power washers are the link between consumer and professional units. While some models have a consumer engine and professional pump, others comprise a professional engine and consumer pump. Semi- pro washers are designed for frequent use. So, if you take your property upkeep more seriously, this option would suit you well.
  • Professional power washers are manufactured with a professional engine and pump, meaning you can use a professional unit daily. Doing so with a consumer unit would cause the pump to burn out much faster.

If you have never tried power washing vs. pressure washing yourself, you shouldn’t hesitate to ask for assistance. Getting a friend or an industry professional can make it easier for you to choose the method and equipment within your budget, matches your requirement, and solves your problem.
