Efficient Pressure Washers: How to Clean Outdoor Spaces Without Wasting Water

Smart and Efficient Pressure Washers for Heavy-Duty Jobs and More

If you own a home or any outdoor space, chances are you’re familiar with the need for a good cleaning every now and then. You may have a deck that needs to be cleaned, siding on your house that needs to be washed, or a patio that needs to be cleared of dirt and stains.

Whatever the case may be, pressure washers are a powerful tool to help you get the job done. But with so many options out there, it can be overwhelming to choose the right one.

So, let’s dive into the world of pressure washers and see which one is right for you. Water Usage: Efficiency is Key

When it comes to pressure washers, water usage is always a top concern.

Using a pressure washer for a few hours can easily add up to gallons of water used, and this can affect your water bill. One way to ensure that your unit is efficient is by looking at the gallons of water per minute (GPM).

The GPM indicates how much water the unit is putting out, so a pressure washer with a high GPM means that it’s using more water. To increase efficiency, look for a pressure washer with a lower GPM while still having a high PSI (pounds per square inch).

PSI refers to the water pressure the unit is producing. When shopping for a pressure washer, consider purchasing electric or gas-powered models.

Electric pressure washers are typically more efficient than gas-powered units, but gas-powered pressure washers are generally more powerful.

Pressure and Power

The PSI directly relates to the cleaning power of the pressure washer; the higher the PSI, the more dirt and grime can be removed. For example, if you’re cleaning concrete, you’ll want a unit with a high PSI to get rid of stubborn stains.

If you don’t need to clean heavy-duty substances, a pressure washer with a PSI of 1000-1600 is good for everyday cleaning. However, if you have tougher jobs such as cleaning decks or large driveways, you may want to consider a unit with a PSI between 2400-2800.

Pressure Washer vs Garden Hose

In many cases, using a garden hose simply won’t give you the cleaning power you need. Pressure washers are designed to produce a high-pressure stream of water that can blast away the dirt and grime.

Additionally, pressure washers are more efficient compared to garden hoses. A pressure washer can clean a larger surface area faster than a garden hose, and it can remove dirt and stains more effectively.

On the other hand, a garden hose is useful when you’re tackling smaller jobs or when you don’t want to use too much water.

Water Usage for Pressure Washing a House

Pressure washing a house can be a daunting task, it an also lead to high water usage if not done efficiently. To ensure that you’re using the appropriate amount of water, calculate the amount of water and workers needed based on a square footage of the house.

For a one-story house with fewer than 2000 square feet, only one worker may be needed, and the unit will use between 400 – 500 gallons of water. On the other hand, a two-story house with 3000 square feet may need up to three workers and use around 750 gallons of water.

Efficiency: GPM and PSI Relationship

We’ve already discussed how GPM and PSI affect the efficiency of a pressure washer. But do these two metrics work together efficiently?

Generally speaking, a pressure washer with a higher PSI will be less efficient in terms of water usage. To maximize efficiency, look for a pressure washer model that has a lower GPM and a higher PSI.

This way, you’ll still have the necessary cleaning power, but you’ll use less water for the same cleaning job.

Water Temperature for Maximum Efficiency

Last but not least, keep water temperature in mind when thinking about efficiency. Warm water is better for cleaning, as it helps to loosen dirt, grease, and grime more effectively, making it easier to remove.

While pressure washers don’t have built-in warm water features, a few models have the ability to mix hot water with cold water for better cleaning efficiency. In conclusion, these tips can help you choose the right pressure washer to clean your outdoor spaces.

Consider how much water you will be using, the PSI required for your needs, and if your unit is efficient for your tasks. Choosing the right pressure washer can help you cut back on water usage and save money in the long run.

In conclusion, pressure washers are powerful tools for cleaning outdoor surfaces. Consider the water usage, pressure, power source, and efficiency before choosing a unit that suits your needs.

Remember that using warm water can increase cleaning efficiency, but be mindful of the water bill. With the right care and attention, a pressure washer can be a valuable investment for maintaining your outdoor spaces.


1. How much water does a pressure washer use?

A: The amount of water a pressure washer uses depends on its GPM, but it can range from 1.5 – 5 GPM. 2.

What is PSI? A: PSI refers to the water pressure a pressure washer produces.

The higher the PSI, the more powerful the cleaning ability. 3.

Is it better to use a gas-powered or electric pressure washer? A: Electric pressure washers are more efficient than gas-powered units, but gas-powered pressure washers are generally more powerful.

4. Can a pressure washer damage surfaces?

A: Yes, excessive pressure can damage surfaces such as wood, so it’s important to adjust the pressure and use appropriate attachments for different materials. 5.

Can pressure washing a house save water compared to hand washing? A: Yes, pressure washing can save water when used correctly, but it’s important to calculate the necessary amount of water and workers needed for the job.
