If you are buying a pressure washer, the GPM is important to consider. GPM or gallons per minute measures how much water comes out of your VEVOR pressure washer. How much water comes out of the unit determines the cleaning power of it.
Therefore, you need to know exactly what GPM is, what it means, and more. We are here today to provide you with all the information you need to decide on a pressure washer in terms of GPM. So, what GPM pressure washer do you need? We’ll take a closer look at all of the factors you need to consider, and more.

What is GPM?
GPM stands for gallons per minute. This is a measure of how much water comes out of a pressure washer. In other words, it’s a measure of the rate of water flow. It’s an indication of how much water comes out of the pressure washer every minute it is in operation. You need to understand GPM to understand how effective a pressure washer will be.
If you’re interested in knowing the calculation, we can provide you with that information too. Simply divide the total water volume in gallons by the number of minutes it took to use that amount of water. For instance, if a pressure washer uses 10 gallons in 4 minutes, the GPM would be 2.5. As you can see, making the calculation is quite easy.
GPM is important to know, and it’s just as important as PSI. Remember, GPM is how much water is being used per minute. On the other hand, PSI, or pounds per square inch, measures the force of that water flow. So, the heavier the cleaning job, the more GPM you’ll need. GPM is important because it determines how much water is used to flush away the debris.
Why Does GPM Matter for Pressure Washers?

GPM is important to consider for a number of reasons. More than anything else, the GPM of the pressure washer determines how effective it will be at any cleaning job. How much GPM a pressure washer has influenced its water consumption, speed of cleaning, and more. The following are all reasons why GPM matters.
- GPM matters because it determines the speed and efficiency of cleaning. The more GPM pressure the washer has, the faster it can work. This means it has more water flow to wash away grime and debris. If you have a big driveway, having a higher GPM is recommended.
- Surface coverage is another consideration when choosing a pressure washer in terms of GPM. The more GPM pressure a washer has, the more area it can cover in a limited amount of time. For big surfaces like exterior siding and driveways, more water volume is beneficial.
- You also want to consider the GPM in terms of the pressure washer attachments you use. For instance, Rotary nozzles and surface cleaners work better with higher GPM ratings. There are also some attachments that need a minimum GPM to function properly.
- Also consider water consumption. Yes, a higher GPM means that you’re using more water in a shorter amount of time. However, it also allows you to clean quickly. Overall, this might lead to some water and monetary savings.
- The bottom line is that the more GPM a unit has, the more versatile it is. This is especially the case if you have a pressure washer that features an adjustable GPM setting.
How to Choose the Right GPM Pressure Washer for Your Needs
There are a few great ways for you to narrow down the selection in terms of the pressure washer you want. This is how to choose the right GPM pressure washer.
Cleaning Needs
You first need to consider what your overall cleaning needs are. How much GPM your pressure washer needs to have depends on what you are cleaning. First, we have light-duty cleaning jobs. This could be anywhere between 1.0 and 2.0 GPM. For instance, if you want to clean outdoor vehicles, furniture, and even small decks and patios, up to 1.4 GPM should be more than enough. It’s enough to get these items clean without wasting water.
We then have medium-duty cleaning jobs. This could involve a GPM of anywhere between 2.0 and 3.0. If you have a large deck or patio, up to 2.5 GPM is best. However, for something like siding, you might want to go up to 3.0 GPM. That’s more than enough water flow to clean the siding without causing damage. This type of washer is also ideal for lightweight concrete cleaning.
Finally, we have heavy-duty cleaning jobs. Here, you’ll need anywhere over 3.0 GPM. If you’re doing commercial cleaning or have a large driveway, GPM of up to 4.0 is suitable. For removing graffiti and stains, and industrial cleaning, the higher the GPM the better.
The Balance of GPM and PSI
When choosing a pressure washer, always consider the balance between GPM and PSI. More PSI means that the flow has more power. More PSI is better for breaking up hard stains and dirt. However, more GPM means that there is more water to wash the debris away.
The best is if you can get a pressure washer that has both a high GPM and PSI rating. This means that the pressure washer in question is ideal for even the heaviest of jobs.
Portability
Pressure washers with high GPM ratings tend to be fairly large and heavy. They require stronger motors and bigger pumps. This means that they’re generally a bit less portable. However, portability and efficiency are two trade-offs that you’ll need to consider.
Accessories
The other thing to consider here is what kinds of attachments and accessories the pressure washer in question comes with. Make sure that the accessories you want to use are suitable for the amount of GPM the United question can produce.
