    Best Pressure Washers

    Whether you're a home owner or contractor, a pressure washer can be a handy tool to have around. Clear mud, chip paint and more with a quality pressure washer.

    You could buy a perfectly good budget pressure washer for around a hundred dollars. On the other hand, a professional model could cost you well in excess of a thousand dollars.

    In this review, we rate a collection of top pressure washers that would suit the vast majority of home owners. They are designed to clean your car, deck, brickwork, sidings, and more.

    You'll find both electric and gas-powered machines with a variety of useful features in our ratings. To make it to our top five, each contender demonstrated high overall quality and versatility. At BestReviews we never accept free or discounted items from any manufacturers, so you can trust our zero-bias reviews.

    Considerations

    Cleaning Power

    A pressure washer's ability to clean effectively comes largely down to the volume of liquid it is capable of delivering (measured in gallons per minute, or gpm) and the output pressure generated (measured in pounds per square inch, or psi). Insufficient volume gives you a spray that's too fine. Inadequate pressure leaves you with little more than an expensive garden hose.

    User Comfort

    It's not just about how easy it is to control the cleaning action; each pressure washer is also rated for weight, portability, and other factors that impact how convenient it is to use.

    Attachments & Features

    Most top pressure washers have additional attachments. Some include them in the price, and some offer them as optional extras. In this section, we also look at safety features and other functions that make the machine easier to live with and/or better at its job.

    Price

    We've managed to put together a broad choice of high-quality pressure washers while still keeping a watchful eye on your budget. While more powerful gas-powered models do require a larger investment, there isn't as big of a difference between some machines as you might expect.

    Pressure washers are capable of removing the paint from houses and cars. Before you begin a pressure washing project, double check the settings.

    Cleaning Power

    Products we considered

    Campbell Hausfeld

    Our first choice, the Campbell Hausfeld Electric Pressure Washer, sits at the lower end of the scale with output figures of 1900 psi and 1.65 gpm. However, this should by no means be considered an under-powered tool. Some experts  argue that electrical motors can't produce the raw power of gas ones. While this is true, the Campbell Hausfeld copes well in most household situations.

    Products we considered

    Sun Joe SPX3000

    Our second finalist, the Sun Joe SPX3000 Electric Pressure Washer, has more impressive figures of 2030 psi and 1.76 GPM. Like the former, this would still be classified as a light-duty machine but, once again, that's not a criticism. Though there are more powerful models in our shortlist, the Sun Joe still has the capacity to deal with the cleaning tasks most owners will ask of it around the home and garden.

    If you’re spraying a house with paint on it, start from a distance and gradually move closer. This way, you'll be able to tell what distance you can comfortably clean from without chipping the paint.

    Products we considered

    Karcher K 5.540 X-Series

    No review of pressure washers would be complete without a Karcher, one of the leading names in the industry worldwide. In particular, we have chosen the Karcher K 5.540. At 2,000 psi and 1.4 gpm, its raw figures are similar to those of the Campbell Hausfeld — although Karcher claims that up to 50% extra pressure can be gained depending on the accessory used.

    Products we considered

    Generac 6596

    Our first gas-powered model is the Generac 6596 Residential Pressure Washer. Now the figures really start to get impressive. A pressure rating of 2,800 psi, combined with a flow rate of 2.5 gpm, puts this multi-purpose machine very close to the output levels expected of contractor-standard equipment.

    Products we considered

    Simpson MSH3125-S MegaShot

    Finally we have the Simpson MSH3125-S MegaShot Gas Pressure Washer. Like the Generac, it moves liquid at 2.5 gpm, but pressure is higher at 3,100 psi. What's more, Simpson's PowerBoost technology offers even greater at-the-nozzle pressures. No accurate figures are available, but anything over 3,000 psi is considered heavy-duty — which tells you all you need to know.

    EXPERT TIP

    Pre-soaking the surface you want to clean with your pressure washer (with detergent, chemical pre-soak, or degreaser) reduces the amount of time you will otherwise need for the washing.

    User Comfort

    Products we considered

    Campbell Hausfeld

    Although hand-carry pressure washers are available, they are usually the least-powerful models. That's one reason why none made it to our top five. The other reason is that, at 15 pounds or more in weight, they aren't much lighter than something like the Campbell Hausfeld — a powerful machine that weighs just 23.6 lbs. In use, you mostly want to concentrate on the cleaning wand anyway, so you would likely put a hand-carry unit on the floor, negating any advantage. Owners of this machine cite the fact that the Campbell Hausfeld can be used lying down (as well as upright) as a definite plus, allaying any concerns about knocking the lightweight unit over.

    Products we considered

    Sun Joe SPX3000

    At 31 pounds, the wheeled Sun Joe SPX3000 is no heavyweight. Cable length, often a drawback on electrical machines, is a useful 35 feet. This is a popular all-rounder, and a lot of thought has gone into both the location of the dials and buttons and their size. Most of the functions can be operated while wearing gloves — a definite advantage.

    Spraying your painted house from an angle may help you dislodge dirt, but beware: you're also more likely to catch paint cracks at an angle, which could lead to chipping.
    Products we considered

    Karcher K 5.540 X-Series

    The Karcher, at 31 pounds, might require a little more effort to move around, but the quality of its construction, materials, and ergonomics is apparent. It's a beautifully designed pressure washer and the only one we evaluated that has an integral hose reel — something so convenient, you might wonder why all machines don't have one.

    Products we considered

    Generac 6596

    Not surprisingly, adding a gas engine makes a considerable difference in a pressure washer's bulk. The Generac 6596 weighs a hefty 61.5 pounds. While it's obviously not going to be nimble, that's the trade-off you get for the extra power. Having said that, this is no cumbersome brute. We found it to be relatively well-balanced. The wand has an excellent feel, and the unit is fitted with large, never-flat tires that allow you to take it anywhere.

    Products we considered

    Simpson MSH3125-S MegaShot

    The Simpson MSH3125-S MegaShot is a big, impressive machine — all 65 pounds of it. Big controls, big wheels, big welded frame, big Honda motor, etc. This robust machine is no featherweight, and moving it around isn't a finger-tip operation. However, its balance and maneuverability are adequate.

    DID YOU KNOW?

    Applying a coat of wax after power washing an area extends the longevity of the wash job, makes the next cleaning easier, and also enhances the look of the surface.

    Attachments & Features

    Products we considered

    Campbell Hausfeld

    The Campbell Hausfeld is a reasonably well-equipped machine (given its price) with 20 feet of high-pressure hose on a useful swivel adaptor. It's a shame it doesn't have a built-in hose reel, but neither do machines costing four times as much. For safety (and to extend pump life), it only runs when the trigger is actually depressed. It also has a detergent tank for when you want more than just water. At the business end, a spray gun and two different cleaning lances are provided.

    Products we considered

    Sun Joe SPX3000

    The Sun Joe SPX3000 has a similar auto-stop system to the Campbell Hausfeld. It also has 20 feet of high-pressure hose, this time with a spray wand that can be extended 34 inches. That's useful for extra reach, because you should never spray from a ladder. There are five nozzles, plus the notable benefit of not one but two detergent tanks. We did find one common criticism with this machine: some of the unit's plastic fittings are prone to leakage. However, this is relatively easy (and not very costly) to fix by swapping out the existing parts for brass versions.

    The GPM, or Gallons Per Minute, of a pressure washer is determined both by the spray angle as well as the opening size of the nozzle that you use with the washer.

    Products we considered

    Karcher K 5.540 X-Series

    We've already mentioned the Karcher's integral reel in the previous section, but we can’t stress enough how useful it is. Other notable features are the 25 feet of high-pressure hose, the expected trigger safety lock, a detergent tank, a spray gun, and two different wands. (The "Dirtblaster" wand delivers a pressure boost of up to 50%.) The induction motor is also noteworthy; it’s more durable and much quieter than the brush motors often found in cheaper machines.

    Products we considered

    Generac 6596

    The Generac 6596 has one major advantage over any electrical machine: no power cord! It has an easy-starting 196cc motor that's designed for consistently good performance. There's an axial cam pump, chosen because it's less prone to overheating under continual use. Hose connectors are at a convenient height so that you don't have to kneel down to make connections, and 25 feet of a high-pressure hose is provided. Though only one wand is offered, it does have four quick-detach nozzles. A wide choice of attachments are also available to extend reach or for specific functions like large-area surface cleaning.

    Products we considered

    Simpson MSH3125-S MegaShot

    If the Simpson MSH3125-S MegaShot has one outstanding feature, it's the 190cc Honda motor. Honda has an extraordinary reputation for the quality of the engines they supply to manufacturers of home and garden equipment.

    The rest of the machine is of a similarly high standard. The high-pressure hose is kink- and scuff-resistant for longer life. The wand is steel, with a choice of five quick-detach nozzles. Detergent supply is downstream of the pump, meaning a wider choice of fluids is available. (If it's upstream, your choice is restricted because some detergents can damage pump mechanisms). The gun has the usual safety lock and the pump is, once again, the axial cam type. Numerous attachments are available —a huge advantage if you want to maximize the utility of your machine.

    If using chemicals to wash down a surface, make sure that they are approved. Unapproved chemicals or detergents can not only be environmentally unsafe, but can also damage your washer, as well as harm the surface you are using them on.

    Price

    Products we considered

    Campbell Hausfeld

    List price for the Campbell Hausfeld is $116. This is a bargain price for a good-quality, light-duty electric pressure washer. Spend a few dollars more on replacement brass fittings, and the Campbell Hausfeld is a package that will satisfy the needs of most homeowners.

    Products we considered

    Sun Joe SPX3000

    The popular Sun Joe SPX3000 costs $149, and few owners have anything but good things to say about it. They rate it highly for general quality, ease of use, and its ability to tackle anything from lightly soiled vinyl siding to mildewed concrete. The fittings receive occasional criticism, but as with the Campbell Hausfeld, this problem is easily remedied.

    FOR YOUR SAFETY

    Power washers eject water at very high pressures which can cause injury if they hit anybody directly; so do not point the nozzle towards someone. It's also advisable to wear protective eye gear, closed-toe shoes, and water resistant clothing when using these machines.

    Products we considered

    Karcher K 5.540 X-Series

    Karcher is a premium brand, so it's no surprise that the Karcher is a more expensive machine. Having said that, its current price of $293 is a considerably good deal. We note that you're not just buying reputation if you choose this machine. You're also buying superior build quality and the extra thought that has gone into the design and functionality of every inch of this pressure washer.

    Products we considered

    Generac 6596

    You would expect a gas-powered machine to cost extra, so it might surprise you how little difference there is between the Karcher and the Generac 6596. The Generac is a near-professional machine from a premier manufacturer for just $299. If you spend the weekends off-roading your truck, dirt-biking, or any other pursuit that demands tough cleaning solutions — and you don't mind a machine that's a bit noisy — the Generac is your best bet.

    Products we considered

    Simpson MSH3125-S MegaShot

    The Simpson MSH3125-S MegaShot is a contractor-standard machine that sells for a homeowner-friendly price. OK, $640 may not be cheap, but this is a serious piece of equipment by any standards. The Honda engine is a delight. The construction is robust, and the features and functions are designed to strip all kinds of dirt and grime from all kinds of surfaces.

    Take extra care when pressure washing around your plants, windows, eaves, light fixtures, or vents. Also, point the spray downwards to avoid spraying under the siding, which might otherwise cause it to collapse.

    Other Products We Considered

    We evaluated a great many pressure washers before selecting our final five. Here are a few that came close to making the cut — and the reasons they missed out.

    We're always wary of cheap pressure washers, but the Costway 2000 Watt model is put together quite well. The flow rate of 1.6 gallons per minute at 1400 psi is competitive for a light-duty model. Our concern is how long it would actually maintain that performance. With many plastic components, we worry that the Costway’s connections would quickly wear out. To our way of thinking, it’s better to spend a little more on a machine that will definitely last.

    The Greenworks GPW1501 also has lots of plastic parts, but its important connectors are brass. It has 35 feet of power cord and 20 feet of high-pressure hose, so you're not struggling for reach. There is also a useful set of accessories to cover most cleaning tasks. It's not a bad machine, but its closest rivals deliver either more power or a better value.

    AR Blue Clean has a strong presence in the pressure washer market. Their AR393 offers an attractive specification list and is certainly popular. Unfortunately, reliability seems to be an issue, and many owners report leaks. Additionally, it will frequently be compared to the Sun Joe SPX3000 — and the latter is a better machine.

    We expected to rate the Briggs & Stratton 20655 highly. This manufacturer’s motors have excellent power and reliability, and build quality is usually superb. But while this model’s performance is good, the stiffness of the hose makes it awkward to manage, and the clip for the wand is poor. These may be minor flaws, but if you're paying a premium price, you should expect faultless performance.

    EXPERT TIP

    Are you thinking about using your pressure washer to clean your car? An electric pressure washer’s psi could be more suitable for the task. Use caution when applying pressure washer water to your car’s delicate paint.

    Simpson MSH3125-S MegaShot

    BEST OF THE BEST

    With pressure washers, it seems that you get what you pay for. Bigger is better.

    The winner is the Simpson MSH3125-S MegaShot. The Simpson is no lightweight, but it's relatively easy to move around, and the extra bulk is a small price to pay for the power. And it's only large by comparison. This is not some huge, unwieldy monster; it's actually quite well-balanced and ergonomic. It's packed with features that are useful in real-world situations and, above all, it has tremendous cleaning capabilities. You can use it for anything from giving your patio furniture a quick once-over to scrubbing old engine oil off your garage floor.

    All in all, the Simpson ranks at the top in every important aspect that we considered, and it is the clear winner as the best pressure washer on the market.

    You can use the Simpson MegaShot for anything from giving your patio furniture a quick once-over to scrubbing old engine oil off your garage floor.

    Sun Joe SPX3000

    BEST BANG FOR YOUR BUCK

    When it came to choosing the best bargain-priced pressure washer on the market, our decision wasn't quite so easy. The Simpson MegaShot wins the power stakes by no contest, but is it worth almost four times what you would expect to pay for the Campbell Hausfeld? For some users, clearly not.

    The majority of pressure washer owners don't spend the weekend cleaning up after motor sport events, renovating steam trains, or scouring decades of mildew, grime and graffiti off old buildings. They wash the car, spruce up the deck, or give the lawnmower a quick cleaning. They want the simplicity and speed of a plug-and-go electric pressure washer.

    The Karcher is tempting. It's a great machine, but it's the same price as the more powerful Generac, and this category is all about "bang for buck."

    So our choice for the best value pressure washer is the Sun Joe SPX3000. It's one of the lightest machines on our shortlist, and it is very easy to move around. It's not overwhelmed with features, but it does what you need it to do. It has adequate cleaning power for all the "regular" jobs listed above, and that's all the majority of people will ever need it for.

    To be sure, it's not perfect. It's a lightweight, budget-priced model. But it provides all the services that 99% of pressure washer owners will ever need, and unless you are that power user in the 1%, this is the right machine for you.
