Portable and high power pressure washers for blasting grime from patios, decking, cars, and more.

The best pressure washers are essential household tools for cleaning decking and patios. Their grime-busting power makes quick (and super satisfying) work of mildew, mold, and dust when cleaning vehicles or barbecue equipment. In short, they’re a must-have.

When shopping for a pressure washer there are a few things to consider. First of all, there’s the PSI. The higher the PSI, the higher the power of a pressure washer. Also, consider the weight and size of a pressure washer. They should get the balance right between portability and power, so you can take them anywhere and blast through demanding tasks in as little time as possible. That’s why we like the Sun Joe SPX3000. It’s versatile and reasonably priced, with a decent PSI and a lightweight design.See more of our top picks below.

Pressure washers are an incredibly helpful tool to have around the house. These machines amplify the power from your garden hose, using water to blast away all sorts of tough stains on a variety of surfaces. You can use a pressure washer to clean your car, remove mildew from your deck, get oil off the driveway, wash your home’s siding, and much more—without ever having to break out a scrub brush. 

How do pressure washers accomplish these tasks with such ease? When connected to a hose, the machine uses either gas or electricity to power a pump that amplifies the water pressure, shooting water out with 30 to 80 times more pressure than it would have just from the hose. This force can effectively loosen dirt, grime, paint, and more from a variety of surfaces, helping to streamline many of your household chores. Some models even have built-in soap tanks that mix with the spray for even more cleaning power. 

However, shopping for a pressure washer can be a bit confusing, especially if you’re not familiar with the common terminology. You’ll need to find a pressure washer with an appropriate water volume and cleaning force, measured in GSM and PSI, respectively—to make this decision a little easier, pressure washers are often described as light-, medium-, or heavy-duty. Additionally, you’ll have to choose between gas- and electric-powered options, each of which have pros and cons. 

The following guide will help you better understand the nuances of pressure washers, giving you the information you need to pick the best option for your home. 

What to Look for in a Pressure Washer

There are several features you’ll want to consider as you shop for a pressure washer. These factors will determine not only how well the machine performs and what tasks it is best used for, but how expensive it will be, as well. 

  • Water Pressure: One of the most important factors to consider when buying a pressure washer is how much force it creates. After all, more pressure equates to more cleaning power.
    This pressure is measured in PSI, or pounds per square inch. Generally speaking, lower PSI means less pressure. However, that doesn’t mean you should simply buy the highest PSI machine you can find—depending on how you intend to use your pressure washer, a lower PSI may be perfect for your needs.
    Consumer pressure washers often start at around 1,300 to 1,800 PSI. This type of light-duty machine is great for small residential jobs like washing cars, cleaning shutters, washing down lawn furniture, and spot-cleaning mold or mildew. The next step up is around 2,000 to 3,000 PSI, and these machines are often considered heavy-duty, as they can be used to clean house siding, driveways, decks, and other tough stains.
    Finally, machines with 3,000+ PSI are considered professional-grade and are used for industrial cleaning, paint stripping, graffiti removal, and more. These high-end pressure washers are the most expensive, and in general, most homeowners don’t need this much power. 
  • Gallons Per Minute: The other key factor that goes hand-in-hand with PSI is GPM, or gallons per minute. As you might have guessed, this measures the volume of water that goes through the pressure water. Models with a higher GPM will clean faster and more effectively since they’re using more water.
    GPM is directly correlated to PSI—the higher the pressure, the more water the machine will use per minute. Light-duty machines may only use 1.5 GPM, while professional-grade models can reach up to 4 GPM.
    When shopping for a pressure washer, you’ll want to look at PSI first, but keep an eye on GPM, as well. Depending on what you’re using for a water source, you might not be able to support a high-GPM machine. 
  • Power Source: You’ll also want to look at how different pressure washers are powered. There are both gas and electric models available, and each of these styles has its own pros and cons.
    Electric-powered pressure washers are typically less expensive, lighter, and easier to maintain. Additionally, they run quieter and don’t create any harmful air pollution. However, electric models are generally less powerful than gas ones, and you have to use them near an electrical outlet. This type of pressure washer is often best for small jobs around the house, such as cleaning cars, patio furniture, and grills.
    The other option is a gas-powered pressure washer. These machines are much more powerful, and because you’re not confined by a cord, they’re more portable and versatile. The downside is that gas machines require regular maintenance, and they’re louder and worse for the environment. 
  • Pump Type: The pressure washer pump is arguably the most important part of your tool, as it’s what creates the high water pressure. There are two types of pumps that are commonly used: axial pumps and triplex pumps.
    Axial pumps are great for beginners, as they’re easy to use and require little maintenance. They’re best for small tasks around the house and ideal if you only plan to use your pressure washer once in a while.
    Triplex pumps, on the other hand, are a bit more heavy-duty and will serve you well if you plan to use your pressure washer frequently. However, these pumps require more maintenance. 
  • Water Source: What type of water source are you planning to hook your pressure washer up to? Municipal water? Well water? Maybe you don’t have a water source at all!
    This is an essential—yet sometimes overlooked—consideration when purchasing a pressure washer, as the GPM of the machine has to be equal to the pressure of your water supply. For instance, if you purchase a pressure washer that uses 2.5 GPM, your water supply needs to be able to consistently provide that much water. Otherwise, you will likely burn out the motor of your new tool.
    In general, most pressure washers can be safely run on a city water supply, but the same can’t be said about well water. If you plan to hook your pressure washer up to well-supplied water, you’ll want to measure the GSM to ensure it can support the needs of the machine for the duration of the time you’re using it.
    What if you have no water supply? You have a few options. First, you could invest in some type of water tank to run your machine off. Second, there are some small pressure washers that have built-in water reservoirs that you can fill up in the sink or shower. Keep in mind that both these options will give you a limited runtime. 
  • Noise: Some pressure washers are noisier than others. If you have neighbors close by, you may want to opt for a quieter version—electric pressure washers are typically much quieter than gas ones, as their motors run silently.  
  • Portability: Do you plan to use your pressure washer just around the house? Or will you be taking it to various job sites, as well?
    There are several features that impact a pressure washer’s portability. First, the weight of the machine will dictate how easy it is to transport. Further, some models have wheels that make them easier to move from location to location. 
  • Cord Length: If you’re planning to purchase an electric pressure washer, make sure to look at how long its power cord is and whether it’s compatible with extension cords. Many pressure washers recommend that you don’t use extension cords, and this means you’ll be limited to the length of the existing power cord. 
  • Soap Tank: Depending on how you plan to use your pressure washer, it might be beneficial to find a model with a built-in soap tank. This will allow you to simultaneously spray water and soap onto surfaces for a more thorough wash job. However, if you plan to use your washer to remove paint and clean driveways, you may not need a soap tank.
