The 9 Best Pressure Washers of 2024, Tested and Reviewed

Enjoy a sparkling clean patio, deck, driveway, and more

Karcher K5 Premium Electric Pressure Washer displayed on driveway

A pressure washer can power wash stains, gunk, and dirt from concrete paths and driveways, decking and siding, lawn equipment, cars, and more. Gas pressure washers provide more power, but electric pressure washers are easier to use and provide plenty of power for home use.

To help you find the right pressure washer for specific tasks around your home, we tested 20 different gas and electric options, evaluating each for ease of use, noise level, effectiveness, and power.

We found that about 1,800 psi is sufficient pressure for light-duty work like washing cars, 2,000 psi is enough to handle most common jobs like cleaning concrete and decking, and 3,000+ psi speeds up the process for big jobs and provides the reach necessary for cleaning siding on taller homes.

We also enlisted expert advice to help better understand what type of pressure washer works best for different jobs. According to Deane Biermeier, a home improvement expert and current member of The Spruce’s Home Improvement Review Board, “Electric pressure washers with various pressure nozzles are the most valuable for the typical residential user. You likely won’t need to spend the money for a professional-grade gas pressure washer for most household chores.”

We found that our favorite pressure washers deliver high enough pressure to handle everyday cleaning tasks around the yard, with features like wheels and handles for easy movement, multiple nozzles, and detergent tanks for easy soap application.

What We Like
  • Dual detergent tanks

  • Auto shutoff

  • Reasonably quiet

  • Compact design

What We Don't Like
  • No onboard storage for hose

  • No long attachments for floors

The best overall pressure washer we tested is the Sun Joe Electric Pressure Washer, which delivers 2,030 psi at 1.76 gpm. This affordable unit is equipped with dual detergent tanks and five quick-connect spray tips to help you tackle all sorts of cleaning tasks. We used this model to clean a wooden fence, a concrete walkway, and a car.

We appreciated not just the fact that the Sun Joe was relatively quiet for a pressure washer but also its supreme effectiveness. Its different nozzles allow for more or less pressure, depending on the surface being cleaned, making it easy to hit the perfect power for each specific job. After using this washer on our fence and walkway, we noticed a big improvement in their appearance.

The Sun Joe Pressure Washer features a 20-foot high-pressure hose, a garden hose adapter, a 34-inch extension wand, and a 35-foot power cord. It took us around 15 minutes to assemble the pressure washer, and while the task seemed daunting at first, the instruction manual simplified the procedure. Once put together, the pressure washer was very easy to use and maneuvered well on its oversized wheels, even across grass or uneven ground.

This versatile pressure washer can be used for a variety of easy and tough tasks all around the exterior of your home, including cleaning cars and other vehicles, sidewalks and driveways, decks and fences, patio furniture, garden tools, and backyard playsets. You can store two different types of detergent in the dual chambers, switching between them with the selection dial. That's an especially handy feature when washing a car.

Although this is a somewhat compact pressure washer, we were pleasantly surprised with its power and cleaning ability, which are comparable to those of higher-priced machines. Thanks to the long length of the power cord and hose, we never felt restricted. The Sun Joe is small but mighty, and it’s perfect for the average homeowner.

How It Performed Long-Term

After testing the Sun Joe SPX3000-MAX for three months, we've found that it is still worthy of our top spot, standing out for its ease of use and powerful yet compact design. It continues to come in handy, especially for keeping our house, car, and deck in tip-top shape. Although we wish it came with an attachment to clean large areas of concrete and wood flooring, we appreciate the attachments it does have, including those for suds and pressure changes.

What does psi and gpm stand for?

A pressure washer's force 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.

The other key factor that goes hand in hand with psi is gpm, or gallons per minute. This measures the volume of water that goes through the pressure water. Models with a higher gpm will clean faster and more effectively because they’re using more water.

What We Like
  • Lightweight

  • Compact for easy storage

  • Budget-friendly

What We Don't Like
  • Plastic wheels instead of rubber

  • Not suited to heavy-duty cleaning

If you need a lightweight, fairly quiet pressure washer for washing your car, cleaning patio furniture, hosing down sidings and walkways, and similar common tasks, then you'll find that the BLACK+DECKER 1850-PSI Pressure Washer is more than up to the job. While testing, this reasonably priced pressure washer required only 10 minutes to assemble the tool before we began using it to wash a car, wooden fence, and deck.

With 1,850 psi and 1.2 gpm, this isn’t the most powerful pressure washer available, but it’s a fine choice for light-to-medium cleaning projects around the yard and garage. We weren't sure how powerful the device would be, but we were impressed once we started. It quickly removed all manner of grunge and grime from the fence and deck, and the cord was long enough for easy maneuvering.

We also found that it did a great job washing the car, efficiently blasting away dirt and bugs. The soap dispenser made the job even easier, and the car was shining by the time the test ended. As a bonus, we found this pressure washer to be quieter than most similar models.

The pressure washer has a 25-foot high-pressure hose, a 35-foot power cable, an onboard detergent tank, and includes three nozzles. We appreciated the light weight of this washer—it only weighs 22 pounds (the lightest on our list)—but the telescoping handle and large wheels make it extra portable. Best of all, when you are finished cleaning, this compact pressure washer has onboard storage for the nozzles, hose, and cord, and its shape and size make it easy to store; something that can’t be said about many similar pressure washers.

How It Performed Long-Term

After testing this pressure washer for four months, we have no complaints to report. We are still raving about its compact size and powerful performance, and we continue to find it really easy to store and carry anywhere. Plus, we love that it's not too loud, especially compared to the gas models we tested. We think it's an excellent value as well and have noticed no changes in its appearance or performance over time.

What We Like
  • Very powerful

  • Good onboard storage of hoses and nozzles

  • Large onboard detergent tank

What We Don't Like
  • Some nozzles are too powerful for some surfaces

Our top choice for best electric pressure washer is the Greenworks Pro 3,000-PSI Brushless Pressure Washer because it is powerful, intuitive, and has great features. This electric tool has a 14-amp brushless motor that propels water at 1.1 to 2 gpm on 3,000 psi. Its onboard detergent tank holds 1 gallon of soap. Even though it is not cordless, the cord is nice and long at 35 feet, which came in handy for our driveway cleaning project.

We also like that the machine's cord storage swivels so we could remove the cord more easily (similar to a vacuum). All five of the nozzles can be stored on a panel on the handle, and they're neatly labeled on the panel with the degree of angle of the tip. The nozzles were easy to switch out, and there was no leakage or spraying when taking them on and off.

No slouch when it comes to performance. This is a great choice for cleaning decks or wooden fences. We cleaned a back section of a wooden deck that was dark from three years' worth of dirt and grime, and within just 18 minutes, we were able to get it looking much nicer. The turbo nozzle, in particular, really dazzled us: The grime started washing away immediately.

It's worth noting, however, that we started with one of the high-power nozzles and noticed that it was actually damaging the wood. However, once we switched to a lower-powered nozzle, we had no further problems. This was more user error than the machine's fault, but it's worth noting that this is a powerful machine that can damage surfaces if you're not careful. Still, that can be true of any pressure washer.

Overall, while it costs more than many other electric pressure washers, this one can’t be beaten for performance. It's as close as you are likely to get to a gas-like performance from an electric pressure washer, and it's reasonably quiet as well.

What We Don't Like
  • No built-in detergent tank

  • Noisy

Gas pressure washers are typically considerably more powerful than electric models. And if you’re looking for a top-rated gas model that packs a mean punch, after testing the Simpson PowerShot Pro Gas Pressure Washer, we think this is the best choice. We used it to clean a stained concrete driveway, truck, and car. Within minutes, this beast of a machine got rid of stains that had been on the driveway for years. We didn't even have to use the most powerful setting to remove the stains.

This heavy-duty pressure washer delivers 4,400 psi (the highest on our list, along with our best for concrete) at 4 gpm to tackle even the toughest jobs. This unit gets its power from a 420 cc engine, and it’s made from solid steel for durability. The washer’s kink- and abrasion-resistant hose is 50 feet long, and the 13-inch tires make it easy to steer across various terrains, including pavement or grass.

The PowerShot Pressure Washer comes with five quick-connect nozzle tips that can be used for all sorts of applications, such as wood restoration and graffiti removal. It’s a fairly large tool, so you’ll need room to store it in between uses. And, of course, you’ll need to have access to gasoline to fill its fuel tank periodically. 

It took us around 30 minutes to unpack the machine and prepare it for use. We found it a bit tricky to assemble the handles, but once everything was in place, the pressure washer was intuitive and easy to use. However, like many gas-powered tools, it took several pulls of the starter before the pressure washer roared to life, and it did indeed roar. This machine is loud enough that you might want ear protection to use it.

We were admittedly a bit intimidated by this gas unit at first, but once we discovered how powerful and effective it was, we were nothing but impressed. While expensive, this pressure washer gets out even the toughest stains and grunges quickly and easily.

How It Performed Long-Term

After five months of testing, we believe that if you're looking for a strong gas pressure washer, this should be your first choice. It can tackle even the toughest stains quickly and easily and stands up well over time, and many uses. We are impressed by how well it cleaned a car and removed water stains on surfaces from garden planters.

We do want to note that this is not the best option for everyone—this is a loud product, and we wish it was easier to start (it almost requires two people to get it going). It also takes up quite a bit of space so it isn't the best option if you have limited storage space. In that case, we recommend choosing a lighter, smaller model. However, if you have the space and the need for a powerful pressure washer, this is a great choice.

What We Like

  • Two spray wands

  • Onboard hose storage

What We Don't Like
  • Assembly instructions are a bit tricky

Want to wash your car without scrubbing it by hand? A pressure washer like the Karcher K5 will get the job done in no time. We used it to wash a riding lawnmower (it took us about 10 minutes), as well as to clean iron porch railings and rain gutters. While this pressure washer is ideal for cleaning vehicles, that’s certainly not its only function. In fact, we were impressed by how big of a cleaning punch this pressure washer has; it blasted away dirt and grime almost instantly. 

The Karcher K5 has up to 40 times as much pressure as a garden hose, and it includes two wands: the Vario for everyday cleaning and the DirtBlaster for tough jobs. This electric power washer delivers up to 2,000 psi at 1.4 gpm, and it has an onboard detergent tank for easy soap application.

The Karcher K5 has a water-cooled induction motor—a system that can help the motor last five times longer, and it comes with a 25-foot high-pressure hose and a 35-foot power cord. At 32 pounds, it’s reasonably lightweight and rolls easily on its two large wheels. We found it very easy to use the machine, thanks to the flexible hose, good cord length, and easily adjusted settings. It was also very simple to switch between nozzles.

Overall, we were impressed by how much power this little machine packs. It easily handled all of our cleaning tasks quickly and efficiently. We even found it fun to use.

How It Performed Long-Term

After testing the Karcher K5 for over four months, we haven't noticed any changes in its look or performance. We continue to appreciate how powerful it is for such a lightweight, easily maneuverable, and quiet pressure washer. We are curious how the plastic parts will hold up over time, but we have no problems to report so far.

What We Like
  • Great attachment for large surfaces

  • Easy to assemble and use

  • Effective on many different types of messes

What We Don't Like
  • Instruction manual is not very clear

  • No onboard detergent tank

After our testing, we think the Greenworks 2,000-PSI Pressure Washer is a great choice for just about any light-to-medium cleaning task around your home. Thanks to the included 11-inch rotating surface cleaner, it's even more helpful when you have a large stretch of flat surface to clean. We put this device to the test on three such surfaces: house siding, a driveway, and a fence.

We also used it to clean a car with excellent results in just 20 minutes. We started by cleaning the car's wheel wells and body using the 40-degree spray nozzle, which effectively removed soap and grime. Next, we used the 25-degree nozzle to swiftly remove stubborn stains and dried bugs from the car's body. 

Along with the ease of use and maneuverability of the pressure washer, it was its effectiveness that most impressed us. It easily and quickly handled all of the messes we tested it on, blasting away dirt, bird droppings, tree sap marks, mud, and general grunge with minimal effort. Everything looked better at the end of our tests; the fence practically looked brand new. We especially liked the surface cleaner, which quickly blasted an old rust stain off the driveway.

At 2,000 psi, the pressure washer delivers 1.1 gpm. Along with the 11-inch surface cleaner, it comes with three nozzles, a cleaning wand, a 20-foot heavy-duty hose, and a 35-foot power cord. Onboard storage makes it easy to keep everything in place, and the machine itself is fairly easy to set up and use. It took us only 24 minutes to open the box and have the machine ready to go.

Just note that the instructions weren't as clear as we'd hoped, and there were no specific instructions on how to use the soap dispenser, but we were able to figure it out pretty quickly. It’s reasonably quiet, as well, and we were able to talk over it with no problem.

Overall, we think this reasonably priced pressure washer is a great choice for any homeowner who likes to keep a patio, fence, deck, siding, or other large area clean. It has enough pressure to handle just about any kind of mess and uses water efficiently.

How It Performed Long-Term

The Greenworks 2000-PSI Electric Pressure Washer continues to impress us with its powerful water pressure and features—it's held up great during this time and still works like new. We also appreciate how the settings make it easy to transition between tasks.

If we could change anything, we wish that the soap-pick up line (detergent tank) was built into the unit and self-contained so it was easier to move the unit when using soap. But that aside, at this price point, we think it's an excellent choice for many different types of tasks, especially for cleaning flat surfaces.

What We Don't Like
  • Handle a bit flimsy

  • Not very high-powered

Pressure washers can be a bit intimidating to first-time users: They tend to be loud, large, and equipped with various nozzles and hoses that might be overwhelming if you’ve never used such a machine before. However, the Sun Joe SPX3001 is very user-friendly, compact in size, not exceptionally loud, and reasonably powered, making it an ideal choice if you are shopping for your first pressure washer. It took us only 13 minutes to have the machine up and running, and once it was ready, we used it to clean a car, a concrete driveway, and old stone pillars that were encrusted with mildew, dirt, and algae.

The pressure washer was fairly effective at its highest pressure, though some stains, like dried-on paint and oil stains on the driveway, were too tough to remove. Additionally, it did take a few passes to remove heavy mildew. However, it effectively removed lighter mildew and algae growth from a wide range of surfaces without much effort. We felt the pressure washer was easy to use, observing that the nozzles were very simple to change, the washer was light enough to move without effort, the trigger required little pressure to squeeze, and the overall performance was smooth and reasonably powerful.

The Sun Joe SPX3001 delivers 2,030 psi and 1.76 gpm, making it a good choice for light-to-medium cleaning tasks. Its compact design, along with two sturdy wheels, makes it fairly easy to maneuver. One nice feature of this pressure washer is the built-in hose reel, which makes storing the 20-foot high-pressure hose a breeze. You get five nozzles for various cleaning pressures, a 34-inch extension wand, and 35-foot power cord.

  • Hose can get tangled

  • Loud

The best pressure washer for use around your home has enough power and gallons per minute to blast away grime from walkways, cars, siding, and patio furniture but not so much power that it damages surfaces. It should also be easy to use and store. Luckily, the Greenworks Pro 2300-PSI Pressure Washer fits the bill. While testing, it took us only 10 minutes to set the machine up and get it running.

We then used it to wash a car and a stained concrete driveway, both with great results. While powerful, the device washed the car beautifully without any damage, knocking off bugs at the first spray and leaving the car clean and shiny with the second pass. A discolored spot on the driveway came clean immediately after we put the sprayer close enough to the cement.

The Pro 2300-PSI has a brushless motor that delivers 1.2 gpm on the 2,300-psi setting but can deliver as much as 2.3 gpm on a low setting of 100 psi. That, along with the five included nozzles, gives you maximum versatility to tailor your cleaning to the surface being washed. Go lower pressure on patio furniture, cars, and siding, and turn up the pressure for tough stains on pavement and concrete. 

Along with the nozzles, the pressure washer comes with a 25-foot kink-resistant hose, 35-foot power cord, wand, and onboard detergent tank. It’s easy to use; we especially appreciated the startup procedures indicated right on the machine, as well as its maneuverability, compact size, and easy-to-attach-and-detach nozzles. On the downside, the hoses tended to get tangled during use. However, that can be an issue with any electric pressure washer. The noise level was average, as well—although it seems loud, it's about the same as many others we tested.

What We Like
  • Very high-powered

  • High-performance engine

What We Don't Like
  • Tricky to assemble

  • No onboard detergent tank

If you need a commercial-level machine for removing graffiti, washing stained concrete, or other heavy-duty tasks, then you need a model like the DEWALT 4,400-PSI Gas Pressure Washer. We tried the machine on house siding, a concrete patio, and plastic patio furniture. All came clean almost immediately.

This tough piece of machinery is designed for professionals. With the help of its premium Honda GX390 engine, it can blast away dirt, grime, mold, paint, and more with ease. With this kind of power, few common around-the-house messes can withstand the pressure, but this might be more pressure washer than the average user requires.

It took us around 30 minutes to assemble and prepare the pressure washer for use, and we felt the process was somewhat complicated, with online videos for assembly and for adding oil to be more helpful than the written instructions included with the machine. Once assembled, however, we noted that it was fairly easy to maneuver the pressure washer to where it was needed, the hose was very sturdy, and it was easy to swap out the attachments. Like all pressure washers, and especially gas models, the noise was significant but not worse than any other gas pressure washer.

This DEWALT Pressure Washer delivers 4,400 psi at 4 gpm. And it boasts a durable, 50-foot, steel-braided hose that’s more abrasion-resistant than rubber hoses. It has a AAA industrial triplex plunger pump that drives pressure to the nozzle, and it’s easy to direct the ergonomic spray gun and switch out the five quick-connect nozzle tips. At 140 pounds, this pressure washer is the heaviest on our list. Luckily, the wheels make it easy to move the unit from one spot to another.

How It Performed Long-Term

This power washer continues to stand out for its powerful performance, especially for tough jobs like cleaning a cement patio. We found it also came in handy for cleaning off outdoor furniture before putting it into storage and cleaning around the house. While it's not an everyday item, we think this power washer is an excellent one to have on hand and is worth the splurge if you have the space and need for it.

Final Verdict

The best pressure washer, according to our tests, is the Sun Joe 2,030-PSI Electric Pressure Washer, which makes quick work of cleaning dirty or stained driveways, outdoor furniture, cars, and more. However, if you’re looking for something with the kind of power only a gas-powered pressure washer can provide for cleaning away graffiti and other very difficult stains, then the Simpson PowerShot 4400-PSI Gas Pressure Washer (our best gas pick) offers the performance you need.

What size pressure washer do I need to wash my house?

Choosing the right size pressure washer to clean your house depends on the type of materials you’ll be cleaning and the extent of the job. If you’re trying to clean exterior vinyl siding, decks, and patios, the best pressure washer should be between 2,000 and 3,000 psi. For stucco, aluminum, or softwood, choose a pressure washer with a lower psi (1,200 to 1,800 psi) to avoid damage.

Other Options We Tested

Sun Joe SPX2688-MAX Electric High Pressure Washer: This affordably priced and effective pressure washer was previously our best budget pick based on our original testing results. However, after three months of testing, we did note one safety concern: The nozzle attachments have a tendency to pop off when you first put them on if they're not placed on perfectly—and it's hard to tell when they are on right. When they do pop off, they fly off fast. While it's not making our current list, other than that safety concern, this pressure washer continues to be effective at most lightweight jobs, and is easy to set up and put away.

How We Tested the Pressure Washers

We tested 20 pressure washers in our own homes around the country. Every pressure washer was evaluated on several attributes, including effectiveness, design, noise level, ease of use, power, and value.

  • Ease of use: We started by timing how long it took to assemble each pressure washer and get it ready for use, evaluating every step for difficulty. We then judged the machines on the apparent quality of the parts, the included attachments, and the difficulty of attaching and detaching hoses and wands. For pressure washers with power cords, the evaluation also included how easy it was to work around the cord and whether or not it was an adequate length.
  • Effectiveness: Each pressure washer was used to clean at least three different surfaces, which might include fences or decks, automobiles or boats, house siding, windows, driveways and other walkways, and patio furniture. We noted how long it took for the pressure washer to clean the surface thoroughly and how dirty it was, to begin with. For pressure washers with detergent tanks, the test included evaluations of the performance both with and without detergent. 
  • Noise level: While using the pressure washer, we evaluated the machine for noisiness. We tried to see if we could hold a normal conversation with someone else without having to shout.
  • Power: We noted how well the pressure washer's power worked for the cleaning jobs we tackled, taking into consideration the type of power source each model had.
  • Long-term testing: We continued testing the top-performing models for up to five months, recording our observations and any issues with durability or performance, and updated the list accordingly.

What to Look for in a Pressure Washer

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. Our best overall pick, the Sun Joe Electric Pressure Washer, has 2,030 psi, making it a heavy-duty tool for driveways and home siding.

Industrial cleaning, paint peeling, graffiti removal, and other similar tasks call for professional-grade machines with 3,000 psi or more. These high-end pressure washers are the most expensive, and in general most homeowners don’t need this much power. The DEWALT 4,400-PSI Gas Pressure Washer (our best for concrete) is one such tool.

Power Source

You’ll also want to look at how different pressure washers are powered. There are both gas and electric models (corded and cordless) 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 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. Our top choice for electric power washers is the Greenworks 3000-PSI Brushless Electric Pressure Washer, impressing us with its powerful performance during months of testing.
  • Gas-powered pressure washers, like the Simpson PowerShot Pro Gas Pressure Washer, 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 need regular maintenance, have extra requirements for long-term storage, and they’re louder and worse for the environment due to the gas combustion engine. 

Gallons per Minute

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 1.1 to 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.
