Cleaning dirty concrete is one of the most challenging cleaning tasks. Is your pressure washer up to it?
If there is just a light layer of scum, then your little 1500 PSI pressure washer can make a difference.
However, to really give it the full refresh, you are going to need something more powerful.
Most experienced contractors will recommend a 2,000 to 3,000 PSI pressure washer for the most challenging tasks. These bigger machines run at 2.0 Gallons Per Minute (GPM) or higher water flow rate, which helps to release the dirt and to finish the job faster.
They get the job done faster and get you on to the next task — or relaxing with a cold one.
Can you handle this much power?
Caution: 3,000 PSI (pounds per square inch) is a lot of power. When cleaning masonry, use a wide fan tip and avoid concentrating power on the grout. Composite decks recommend a maximum pressure of 1500 PSI. Also, use a wide tip for painted surfaces (like your car) and don’t get it too close.
The Best 3000 Pressure Washers, Compared
Simpson Cleaning Alpha 33425 (3600 PSI/ 2.5 GPM
In our articles on gas pressure washers, we start off with two expensive and professional models.
For this article, I wanted to offer some cheaper models that were also extremely durable.
This Alpha 33425 is about the perfect option for folks who want to buy a professional-grade tool at a residential contractor price.
The first thing that I love about this model is the Honda GX200 engine. The GX series is their professional contractor engine, and it has a few fail-proof designs built-in like the low-oil alert. This helps to protect the engine when you get distracted by a big job or when your teenager is using the tool and forgets to check the oil.
However, we all know that engines aren’t the weak link when it comes to a pressure washer’s longevity. It’s the pump that you have to worry about.
With this model, you are getting the heavy-duty CAT Triplex pump instead of the axial one. Triplex plunger pumps are what all of the professionals are using as they can build up more pressure without failing due to heat or long hours of use.
CAT plunger pumps were invented in the late ’60s and continue to be the gold standard used by the pressure washing industry. You won’t find this level of pump on many residential pressure washers, making this model one of the cheapest pressure washer with a triplex plunger pump.
So when you see that it only produces 3,600 PSI, you’ll be inclined to go buy a cheaper model with the same ratings. This one is backed with a 5-year engine warranty and a 3-year pump warranty.
What you would be missing is the better engine that delivers more consistent power without surging.
It also delivers a better flow of water. At 2.5 GPM, it pushes a large volume of water, shortening how long it takes to finish your cleaning project and letting you get on to the next thing.
This model comes with everything you need, including a 35-foot-long anti-kink hose with 0°, 15°, 25°, 40° nozzles, and a soaping nozzle.
Downsides with this model are that little bolts tend to come loose during use. Retightening these bolts regularly helps minimize shaking and keep it running like new, year after year.
If you need a power washer that will make the other dad’s jealous, this is the model to go with.
Dewalt DXPW60603 Power Washer (3200 PSI/ 2.8 GPM)
This contractor-grade Dewalt fills an important niche. For the renovation expert who needs to quickly strip paint and graffiti, this heavy-duty model is designed to spend all day in the truck, going from job to job.
As with the Simpson Alpha above, this model has the CAT Triplex plunger pump design. Once again, this is the best quality of pump that you could go with and delivers an amazing amount of power with a lifespan to match.
For starting your pressure washing business, cleaning a fleet of trucks, or for regular use on the job site, the Dewalt DXPW60603 has the durability you are looking for.
The wheelbarrow styled cart with large pneumatic wheels makes it easy to move around, and the quick-connect nozzles store handily in their assigned spots, and the 25-foot high-pressure hose and cleaning wand have handy built-in storage areas.
Standing behind this entire kit is the 3-year engine warranty and 2-year pump warranty, which is backed by the Dewalt brand.
It makes this model a real no-brainer.
Simpson Cleaning MSH3125
If you are going to use your pressure washer regularly, or hope to one day do commercial work, the Simpson Cleaning brand is an excellent place to start.
This Megashot model has some added durability built into its features. For starters, it has the Honda GC190 engine. These motors are super easy to start on a single pull, and they have that legendary lifespan of the Honda engine brand.
While the axial pump on this model isn’t as exciting as what is found on the Megashot is a highly reliable pump that holds up well and is better than some of the cheaper options commonly used.
Something I find enjoyable about this model is the quality of the wand. The nozzles clip in securely to the quick connect end, and the high-pressure spray wand has ergonomic grips for hours of use.
The other nice feature is that it has meets the EPA’s ratings for use in California.
The warranty on this model is a 2-year warranty on the engine and one year on the pump. For the homeowner who wants a 3000 psi gas pressure washer that they can use weekly, this one would be my top pick.
Generac OneWash 70191 Pressure Washer (3100 PSI/2.5 GPM)
Suppose you need a portable pressure washer, the electric models can be good for loading in your car. Gas pressure washers deliver the best power and are quite portable. Given the option, these are always my first choice for cleaning jobs.
The Generac OneWash has quite a few variations from 2900 PSI up to 4200 PSI. The 196 CC OHV engine sips gas and lets you work longer between refills.
I find this 70191 model to be in the sweet spot. It has enough power to get the job done quickly, while still being quite affordable.
The OneWash brings a unique feature to their product. They give you access to the flow regulator with a large, easy to adjust dial.
This lets you dial the power down when working on delicate surfaces. You can safely let your teenager clean the car without worrying as much about them damaging the paint.
But if you need to pressure wash the driveway, you can turn it up and get the full 3100 PSI.
This feature gives you the benefit of having four pressure washers in one.
This model also has a detergent tank, which makes it easy to run soap with the water spray for better scrubbing ability. Just fill-up the soap dispenser and connect the hose. This lets you move around the yard easily without having to stop and pick up a container of detergent (or worry about it getting knocked over).
Generac backs their products with a 3-year warranty. However, they have a lot of caveats. For example, you are supposed to change the oil in the first 5 hours of use and then drain the fuel at the end of the season. These are good reminders for any pressure washer, but it sounds like Generac may enforce those rules more aggressively.
Powerboss 3000 MAX (3000 PSI/ 2.0 GPM)
I probably shouldn’t list this high-pressure washer from Powerboss so highly on my list. It doesn’t have all of the bells and whistles of the other brands. (For example, it offers four nozzles instead of 5. And 10-inch wheels instead of 12-inch ones. And a detergent siphon hose instead of a built-in detergent tank).
But what it does have is raw power backed by some of the best brand names in the industry, packaged together at an affordable price.
For starters, it has the Honda GCV160 engine. This is part of the residential lineup that Honda makes, and it uses its smaller, 160 cc engine for better gas conservation while going with a verticle engine shaft to save more dollars.
Yes, this is the smallest engine on our list, but for residential users, it delivers that power you need.
Then there is the simple, axial cam pump. These pumps are cheap to replace if they ever fail and reliable for getting a consistent, smooth stream of water.
The four quick-connect nozzles let you customize your stream to the different tasks at hand.
For the shopper who wants the Cheapest 3,000 PSI pressure washer that also is made from top-quality parts, this is a strong contender, and one of my personal favorites.
Stanley SXPW3124 (3100 PSI/2.4 GPM)
If you already have a garage full of Stanley tools, then you have already gravitated towards the familiar yellow branding color.
This power washer offers a smaller format than most of the ones on this list, which makes it handy when going up and down stairs or loading it in a car. The large, 12-inch tires aren’t quite as easy as the pneumatic options for rolling over obstacles, but they also never run flat, making it a worthwhile tradeoff.
The 25 feet of non-kinking high-pressure hose is pretty standard, but the spray wand is more ergonomically designed than most.
You also get their turbo nozzle, which is extremely effective at removing built-up mildew and stains.
If you do run into warranty issues with this model, just call the phone number printed on it. A fascinating note is that this model seems to be made by Simpson for the Stanley brand. As you can see from this list, Simpson seems to be a good brand.
If you want a smaller model that still delivers 300 psi of water pressure, this one is a strong contender.
Karcher G2900X Gas Power Washer (2900 PSI/ 2.4 GPM)
The Karcher brand is popular for its commercial-quality tools. Their tools have been used for large, federal projects such as cleaning Mount Rushmore, so they enjoy the brand recognition from that.
Their high-end products are considered the gold standard for industrial cleaning.
This residential model is great for delivering mobile cleaning power around the house. It uses a 196 cc engine that sips gas for a longer running time between filling. The soap dispenser can be removed and filled (or emptied), making it easier to move around with soap.
The spray gun is very similar to the other high-end models with a long wand for reaching those tall spaces. The quick-connect nozzles make it easy to adjust your spray for the different tasks.
Where the Karcher excels is in their better warranty. You get a 3-year warranty on the engine and a two-year warranty on the pump. That is more than just about any brand I have run across and speaks to Karcher’s belief in their products.
Toro Briggs & Stratton 3100MAX (3100 PSI/2.1 GPM)
Toro is a well-recognized brand by homeowners who shop locally, but it tends to get overlooked by online shoppers.
Hopefully, this blog post helps fix that.
Toro has developed some unique features that make this pressure washer an especially useful tool.
The first handy feature is that it has a high-flow option. This allows you to decrease the pressure to 150 PSI (about 3x what you get from a garden sprayer) while still delivering 150 PSI. This high flow mode is ideal for rinsing dirt away after pressure washing or for cleaning your car without damaging the paint.
However, you are going to be buying this tool for the ability to deliver 31 00 PSI of cleaning power. Whether you are using one of the seven options on the included nozzles or attaching this to a pavement scrubber, this is a powerful tool.
This model is similar to the Simpson design in that it does not have a detergent tank, but has a siphon hose that you can use for adding soap to your water. A lot of folks skip the soap dispenser and instead use a foam cannon when working on their cars.
Briggs and Stratton is a more affordable engine but seems to hold up quite well. With pressure washers, the engine doesn’t seem to be the biggest failure point, so I’m fine with saving a little money on this, especially since Briggs&Stratton engines have always held up well for me.
Overall, this is an ideal power washer for the homeowner with a lot of easy-to-use features.
Suyncll Electric Pressure Washer (3800 PSI/2.8 GPM)
Most electric pressure washers struggle to output 3,000 PSI. The ones that do manage a high-pressure output do so by dialing back on the water flow.
This electric power washer manages to deliver a high-powered stream of water while also pushing a 2.8 GPM water flow, similar to the gas-powered models.
It also has a 35-foot-long power cord, which gives you a longer working range than most of the other models on this list.
One of the unique features that you occasionally find on electric power washers is the Total System Stop. This TSS lets the entire system turn off when you release the wand trigger. Not only does it extend the life of your tool, but it also makes for a much quieter experience.
Whether you are cleaning your patio furniture, your RV, or your motorcycle, this Sunycll model brings more power than most of the models in its class.
Paxcess XWasher-P2 (3,000 PSI/1.76 GPM)
The Paxcess XWasher is another electric pressure washer with a 3,000 PSI rating. The Paxcess brand does not have as much brand recognition in the United States but seems to have more use in European countries.
The unit itself is fairly light at about 24 pounds, making it easy to carry upstairs or to wheel around vehicles. The large handle helps with maneuverability.
One of the unique features is the built-in hose reel for coiling the high-pressure hose. This makes it easy to wrap up after a day of cleaning and provides a convenient place to store your hose and attachments.
The nozzle is another unique feature. Instead of requiring multiple spray tips that you pop in and out, this offers one adjustable spray nozzle.
The 25-foot power cord and 26-foot hose length give you plenty of moving room.
It also has an onboard detergent tank for adding a surface cleaner and deep-cleaning grime and mildew.
As a portable pressure washer with a lot of power, the Paxcess P2 offers one of the most intriguing options.
Greenworks 1950 Cold Water Pressure Washer (1950 PSI/ 1.6 GPM)
A lot of my readers ask me about the Greenworks brand. It looks similar to the SunJoe, and many folks already own one of their other products.
The Greenworks has the advantage in that they don’t seem to overstate the pressure their sprayer produces. This model has a bigger motor than most of the models on this list. It is a 13 amp motor but uses an induction design, which is normally only found on the largest motors (such as those used on cabinet table saws).
Seeing how reinforced this washer is, it makes me skeptical of the other electric power washers that claim a 2,000+ PSI rating. I find this model’s claimed 1950 PSI output to be quite believable.
It includes a soap dispenser that mixes your cleaner at a 10:1 dilution. Simply hook up your garden hose and choose one of the four included nozzle tips to start cleaning. You have an “A” side and a “B” side, which lets you run two cleaners at once and toggle between them.
Greenworks also has a wide array of attachments that you can add to the tool for even more cleaning options.
Backed by a 1-year warranty, this might be one of the most well-built electric-powered pressure washers on the market.
Sun Joe SPX3000 (1450 PSI/1.76 GPM)
It is difficult to find a 3,000 PSI electric pressure washer. Around 2,000 PSI is the maximum that you can commonly find.
This Sun Joe is a strong consideration for those who don’t mind compromising on power in order to get an electric model.
It has an internal load rating of 2,150 PSI, but the working pressure at the tip is around 1450 PSI. This is common with all of these electric models, but Sun Joe is more upfront about their pressure calculations than many of the other models.
For keeping things clean around your house, this is an excellent choice. You can clean the boat and RV, keep the car looking sharp, and rinse down the driveway and the gutters. An investment here is going to keep your house looking sharper than all of the others on the block.
They also have a better, no-questions-asked satisfaction guarantee that makes this model a sure bet.
If you can compromise on power, this is a good electric option to consider.
How Much PSI Do I Need?
For cleaning a car, lawn equipment, and the side of your house, a 1500-2,000 PSI pressure washer will do the trick. You can even clean concrete with it, and you will notice that your driveway is noticeably brighter.
However, at 3,000 PSI, you’ll find that you can deep clean mildew and aged surfaces in half the time. You do have to be careful, as anything over 2,000 PSI makes it easy to take the paint (or clearcoat!) off of a car.
Should I Buy Gas Or Electric?
Gas-powered pressure washers are one of the best models out there in terms of power. However, they do require you to add gasoline and make sure the oil is topped off.
For the homeowner, electric is probably the more convenient option– especially if you already have an electric lawnmower. However, they will lack a little bit of power. They also are not likely to hold up to daily use like a gas-powered power washer will.
Is A Soap Dispenser Important?
Almost all of these models either offer an onboard soap dispenser or a tube that can be inserted into a bottle of detergent.
The built-in dispensers are handy in that you can move the soap with you. However, you have to pour the soap out of the bottle and into the dispenser. Most professionals who I have worked with have preferred the models that simply require them to run a tube to their detergent bottle.
Quick Attach Nozzles
Most of the nozzles are quick-attache nozzles that make it easy to switch between nozzles and attachments. There are a few models — like the TORO above — that have a unique, adjustable nozzle. However, it still connects with a quick-connect mechanism.
Not only is the warranty important, but also the company behind it. If a company has only been around for a year or two, there is no guarantee that they will be around when you need them.
If you are planning on using the pressure washer regularly, you will want to go with a more recognizable brand that has good customer support.
