Aside from professional and industrial applications, owning a pressure washer can be a highly effective way to keep your deck, patio, and driveway clean. They can even pay for themselves by saving you time and money spent at the car wash.
We bought 10 pressure washers at full price from the same websites you would, and judged each unit based on a series of rigorous tests to determine which is the champion of high-pressure spraying power. To do so, we devised a myriad of challenges to scrutinize each washer's cleaning power, portability, ease of use, and accessory organizational systems.
In our extensive testing, we found that the Westinghouse WPX3200 pressure washer is the best of the best, and its cleaning performance is simply unmatched.
If you prefer an electric model with superior soaping capabilities and want to save a substantial amount of cash, the LWQ S5 is highly portable and outperforms many pressure washers that cost a pretty penny more.
If you're interested in a pressure washer with enough grit and brawn to handle the biggest, dirtiest jobs, then the Westinghouse WPX3200 is our pick for you. This is the most powerful machine throughout our entire reviewed lineup, producing a stunning 5980 CU of power, more than 1000 CUs higher than its runner-up. Although this machine appears bulky, we found it to be surprisingly nimble and easy to maneuver, thanks to its massive wheels. The built-in storage nook for its 25-foot hose is a significant bonus, enhancing convenience when packing the washer up after a job. However, this device truly shines through with its powerful pressure-washing capabilities. Our testers' initial reactions when firing it up were consistent throughout testing: “This machine is a beast.” There was not a single job during all subjective and objective testing that was too much for the Westinghouse WPX3200.
For all of these highlighted strengths, the Westinghouse WPX3200 did come with some weaknesses. It is one of the largest and heaviest models we tested, and our team noted that “the gas engine is LOUD.” By choosing a petrol engine, you are also choosing an option that comes with fumes, smoke, potential gas or oil leaks, and routine maintenance. Electric pressure washers don't require routine maintenance, but they also don't offer nearly as much power as their counterparts. All factors considered, the WPX3200 is one of the leading pressure washers we tested, truly out-scrubbing its competitors when it comes to cleaning power. If you would like something that can still tackle bigger tasks but without all of the noise, fumes, and maintenance associated with gas machines, take a look at the electric Greenworks GPW3002. For something smaller and highly storable, consider the Westinghouse ePX3500. Although it has a significantly smaller footprint, it comes with less cleaning power.
When you need a grab-and-go pressure washer that weighs about as much as a small microwave, look no further than the Westinghouse ePX3500. This is one of our favorite electric models we tested for a myriad of reasons. This machine requires zero maintenance, unlike gas-powered options. Its cleaning power is just above 1900 CU, making it a suitable washer for nearly any household job. Once we attached the included soap nozzle, this miniature machine stood out, and our testers noticed, “there was still enough brawn to bust through dirt, bugs, and detail those crusty crannies” during our vehicle washdown test. After a job is complete, the ePX3500 remains a winner by being light enough to carry and small enough to fit in practically any household storage space, including a closet if needed.
Like most products we review, the ePX3500 isn't without its drawbacks. If you need serious scrubbing power, our testing proved that its little electric motor couldn't handle a larger job or task requiring industrial strength. Our testers noted, “We weren't surprised by these results, given that this tool's price is modest and its build is small, portable, and somewhat insubstantial.” We also encountered issues when navigating uneven or challenging terrain due to the unit's light weight and small five-inch plastic wheels. If your next project requires raw and direct cleaning power, consider taking a look at a gas-powered model such as the Simpson CM61083. On the other hand, if you appreciate the idea of little to no maintenance and still require major power, check out our highest cleaning-rated electric model, the Greenworks GPW3002.
The Greenworks GPW3002 is the most powerful electric model in our test fleet, producing impressive results time and time again through our cleaning metric. This potently powered pressure washer puts out over 650 CU more than its comparable electric opponents, emitting a serious 2675 CU. Our testers were impressed with how well this rugged machine cleaned a vehicle during comprehensive testing. When it came time to store the machine for the day, its thoughtfully designed cord and hose storage facilitated superior organization by utilizing hooks and bungees, further adding to this machine's ease of use. Even before tallying all our results, our testers noted, “The Greenworks is a supremely capable, robust, and vigorous cleaning unit, especially when compared to its other electric counterparts.”
Even though the GPW3002 is a real power player, it didn't come through our trials without some downfalls, the most noticeable being its massive stature. The heavy-duty steel frame is larger than nearly any other electric washer and weighs a stout 47.6 pounds, making our testers regard that, “This beast would be a nuisance to lift in and out of a vehicle, even if it wasn't nearly as bulky.” We also discovered that this particular piece of equipment is ergonomically uncomfortable to pull around and features a design reminiscent of a lawnmower. When attempting to push, we were again met with discomfort. If you're on the hunt for a washer that can be easily lifted in and out of a vehicle, check out our lightest options, the LWQ S5 or Westinghouse ePX3500, both of which weigh under 20 pounds. Alternatively, if the Greenworks model does not provide enough power, then you'll want to dive into either gas-powered models, the Simpson CM61083 or Westinghouse WPX3200.
One of the most common uses for a pressure washer is to clean and detail a vehicle, and boy is that where the LWQ S5 shone through this stacked field of competitors. The designers of this dazzling little unit included an attachable foam cannon, which had testers commenting, “This little washer spewed out enough suds to not only effectively coat the car but absolutely douse it.” At only 16.8 pounds, it's by far the lightest option we tested while still producing 1962 units of cleaning power. This took our whole team by surprise, considering that it's such a small and compact machine, occupying only 1.9 cubic feet of space. Overall, the LWQ S5 has sufficient power and portability to tackle most home property projects.
With such high mobility and a fair amount of cleaning prowess, it was, however, not a surprise that the LWQ had to make compromises in other aspects. When we opened the box, we found that it required the most assembly. Upon use, we noticed that it is constructed from less substantial materials than all other pressure washers in our lineup. When washing and pulling the unit around, the LWQ tipped over constantly due to its small plastic wheels and top-heavy design. Our lead tester even stated, “No matter how we push or pull, it is downright awkward to drag around.” There is also no circuit breaker integrated into the power cord, which raised some concerns, considering that every other manufacturer we tested provides one. If portability is still a priority, then the SunJoe SPX3000 or Westinghouse ePX3500 are two of the lighter options tested.
The LWQ S5's glistening qualities are enhanced even further with the included foam cannon.

How We Tested
To begin the review process, we first needed to get a handle on each machine, its specific features, feel, and power. To accomplish this, we spent hundreds of hours jetting, soaping, and washing every available object and surface. After gaining a subjective understanding of all tools, we proceeded to test and record hard data across a wide range of parameters, including weight, size, noise emissions, flow (gallons per minute or gpm), pressure (pounds per square inch or psi), and Cleaning Units (CU). For further evaluation, we assess washer performance through a sustained distance test using a trough ramp at 25 degrees and record how far each machine can hold a bocce ball. We cleaned everything that needed soap, from siding and gutters to driveways and vehicles, noting how each unit differentiated itself during the washdown process. We pushed, pulled, hauled, carried, and transported even the largest of units to assess portability. We used a professional sound meter at multiple distances and measured decibels while subjectively noting any irritating or loud noises. Throughout all these tests, we paid particular attention to how easy each pressure washer was to use, from assembly and inlet location to hose, cord, and nozzle storage. For more on our testing process, see our how we test article.
Our pressure washer testing is divided into four different metrics:
Cleaning (45% of overall score weighting)
Portability (30% weighting)
Noise (15% weighting)
Ease of Use (10% weighting)
All of our metrics carry weight, but some are more consequential than others in determining final scores.

Analysis and Test Results
We judge all of these pressure washers based on their cleaning power, portability, noise level, and ease of use. It is paramount first to consider what type of tasks you will be accomplishing with your pressure washer and how complex those tasks might be. It's also essential to weigh features and functions such as soapiness, power, storability, or sturdiness, as these are all factors that may hold significance for you, before purchasing a new pressure washer.
Worse Value
Better Value
What's the Best Value?
The association between a power washer's price and performance is not necessarily a straightforward formula. Cost can vary depending on which characteristics are most important to you. If you use your tools intensively and require a strong stream of water, the Westinghouse WPX 3200 has a gas engine that will last longer but will also set you back a pretty penny. It's a relatively expensive model that offers near-industrial cleaning power compared to any other consumer washer we tested.

Conversely, if you need a budget-friendly product, the Westinghouse ePX3500 has enough power and soapability to finish most household jobs. It is less robust in terms of build quality compared to the majority of our lineup, but it redeems itself with supreme portability and storage capabilities. For someone needing to make a cost-conscious purchase while still maintaining a small size, the LWQ S5 is another affordable option with a ferocious foam cannon attachment that is perfect for washing a vehicle.
With its additional soap bottle and cannon attachment, the LWQ S5 is the superior soaper of all pressure washers we reviewed.

The two types of pressure washers we tested and reviewed are gas and corded electric models, each coming with its associated pros and cons. Gas-powered machines can require dedicated containers for mixed gas/oil for 2-cycle fuel, regular gasoline, oil, filters, and the time needed for routine maintenance. Corded units come with their own associated costs, such as the need for extra extension cords or a hiked electric bill. Overall, an electric pressure washer can save you some money and time, which might be a key aspect to consider before making a purchasing decision.
Pressure washers can vary significantly in terms of price, performance, size, weight, and the type of energy required for operation.

Cleaning
A pressure washer's primary purpose is to clean, so our team decided that the testing results for this metric should account for 45% of the overall score. To begin our cleaning assessment, our team used each pressure washer for hours, gaining a feel for its effectiveness throughout numerous trials — cleaning driveways, fence boards, gutters, wheelbarrows, decks, and dirty vehicles. All of these jobs come with their difficulties and are tough to recreate, so we devised a series of easily repeatable tests to gather some objective data.
It was essential for us to test every system on a spectrum of different surfaces.

To begin our assessment for this metric, we set out to measure the cleaning power of each washer, and yes, there is a unit of measurement for that. Cleaning Units, or CUs, are used to evaluate the effectiveness of various household and industrial cleaning tools, such as vacuums and pressure washers. A machine's Cleaning Units can be calculated by simply multiplying a machine's pressure or pounds per square inch (psi) by its flow or gallons per minute (gpm). To find both of these integers, we used two different tests.
By finding psi and gpm, a machine's cleaning power is easily calculable.
Credit: Natalie Kafader
Determining a washer's psi is relatively straightforward, so we attached an industrial-strength pressure gauge to each machine in our lineup and recorded the results. We observed that most of the electric-powered washers produce less than 2000 psi. Two models did stand out, however.
An in-line pressure gauge, an enclosed bin, a scale, and a little math were used to determine psi and gpm.
The Craftsman CMEPW2400 pushed just above the 2000 psi mark with 2075 pounds per square inch, while the Greenworks GPW3002 severely outpaced all other electric models, running a very impressive 2700 psi. Although the Greenworks had the highest tested pressure, when it came to gas-powered models, there was a general advantage. The Simpson CM61083 exerted an impressive 2300 psi, and the standout pressure of the Westinghouse WPX3200 was 2600 psi.
Our next numerical calculation was the rate of flow, or gallons per minute. This required a bit more construction, so we set to work creating an enclosed box that we could spray each washer into for a 60-second period. After this time, we weighed the bin and were able to calculate the amount of gpm exerted. Again, the gas-powered models outperformed their electric competition.
The Simpson CM61083 maintained 2.16 gpm while the Westinghouse WPX3200 spewed out the most water at 2.3 gpm. Most electric units streamed out around 1 gallon per minute, give or take up to 0.08 gallons, but there was a standout in the 1.31 gpm emitted by theLWQ S5. We could now begin crunching through our Cleaning Units formula. By prioritizing a larger flow over its meager 1500 psi of pressure, the tiny LWQ S5 ended up producing an average result of 1962 CU.
We found that the gas-powered pressure washers consistently produce superior cleaning power. With over 1000 CU more than any other machine, the Westinghouse WPX3200 neared industrial-grade strength with a ferocious 5980 CUs. This was followed by the Simpson CM61083's 4968 CU of force.
The Greenworks GPW3002 was the most impressive electric pressure washer in terms of power.
Credit: Laura Casner
Once we entered the realm of corded electric pressure washers, all products dropped below 2000 CUs except for one. The Greenworks GPW3002 produces an outstanding combination of pressure, matched with a flow rate of just under 1 gpm, making this electric product a scouring sensation with 2675 units of cleaning power. Following the leaders was an extensive list of median cleaning-powered units; below is a table of our final calculations of psi, gpm, and CU.

To validate our calculations and gain a fresh perspective on each unit's exerted cleaning power, we devised a series of slightly more hands-on trials. We began by constructing a 12-foot-long trough with wooden bumpers and etching distance markers on either side for accurate measurement. Then, we set our scientific sluice at a 25-degree angle before placing a bocce ball and each washer at the bottom. One tester then proceeded to spray the ball up the embankment while another recorded sustained distance in this trial for raw power.
Our bocce ball test provided us with real-life, objective data in addition to our other recorded results.

Finally, we finished our cleaning metric tests with a bit of bubbles and examined how each pressure washer fared at soaping and cleaning a vehicle. We used all included nozzles or blasters, filled reservoirs, and switched to sud settings. While a few of the tested products only had an inlet hose that could suck from a soap-filled container, we were excited to see a few distinguished washers with large reservoirs and impressive saponifying nozzles.
The LWQ's soap cannon covered all of our cars in full-on frothiness.

The LWQ S5 manufacturers include a foam bottle cannon that dispenses and coats a vehicle more thoroughly than any other unit within our reviewed lineup. Close on its heels are the Greenworks GPW3002 and Westinghouse ePX3500, which both dispense enough soap to clean any car, toy, boat, and more. We also discovered a helpful feature that would be beneficial to anyone applying two different products in the same wash. The SunJoe SPX3000 is equipped with two soap reservoirs and a dial to switch between them, allowing users to select a combination of prewash, soap, wax, or other additives.
By combining our measurements of pressure, flow, cleaning units, our custom ramp test, and soaping performance, we calculate a total Cleaning score.
Overall, our discoveries led to one obvious conclusion — both gas-powered pressure washers, the Westinghouse WPX3200 and Simpson CM61083, swept our Cleaning metric by providing higher rates of flow and pressure, resulting in remarkably larger CU ratings.
The Simpson exerted some of the most pressure we saw throughout our testing process, effortlessly clearing debris from any surface.

The next washer to come with plenty of force to match a wide array of labor is the most powerful electric pressure washer we purchased and reviewed. The Greenworks GPW3002 not only boasts plenty of power, but it also comes with a great set of nozzles and demonstrates outstanding soaping performance, effectively scrubbing away the crud.
The Greenworks GPW3302 maintains the best cleaning score among its electric-powered competitors.

Behind these few washers, a large pack of medium-performance pressure washers is available, including the Dewalt DWPW2400, Craftsman CEMPW2400, both Sunjoe products, and the LWQ S5. The only one that performed at a low level in our Cleaning metric is the Stanley SHP2150.

Portability
When it comes down to conveniently utilizing a pressure washer, mobility and storage are primary concerns, which is why we chose to base 30% of the final score on our Portability metric. We intend to evaluate objective information first, so we focused on two key areas: weight and size. Our scoring shows that lighter and smaller options performed better, while heavier and clunkier models fell back in the rankings. For a fair assessment of each model, we took into consideration how easy the washers are to load for transport between locations and whether they are laborious to push or pull once on-site.
We began our analysis by weighing each unit and found that many of the models tested weighed more than 40 pounds, similar to that of a five-gallon bucket full of water. Both of the gas models we weighed were well above that, with the Westinghouse WPX3200 clocking in at 63.6 pounds and Simpson CM61083 rounding out at the heaviest 67.6 pounds. It should also be mentioned that this weight was dry, so once oil and gas are added, these machines can weigh more.
The Simpson's weight makes it a rather unwieldy machine.
Credit: Ian Pearman
The heaviest electric washer is the Dewalt DWPW2100, weighing 58.1 pounds. However, not surprisingly, the common trend is that electric corded units are generally lighter overall. We found the Westinghouse ePX3500 at a mere 18.7 pounds and an even lighter 16.8 pounds for our featherweight LWQ S5.
At under 20 pounds, the Westinghouse ePX3500 is one of our favorite portable pressure washers.
Credit: Natalie Kafader
Our next job was to measure every unit and its footprint. We again found a common thread between size and weight emerging. Both gas options are generally larger in stature, but this time, the Westinghouse WPX3200 took away the award for largest pressure washer, measuring 38.5 inches tall, 25.5 inches long, and 19.75 inches wide and taking up 11.2 cubic feet. Once more, the two smallest units are the LWQ S5 and Westinghouse ePX3500, which are both lightweight and small enough to be easily tossed onto a shelf or stored in a closet.
This brings us to our next topic. Storability. All units we measured will be able to live in a garage with no problem, but there are only a few models, such as the previously mentioned LWQ and ePX3500, which are small enough to stow in a multitude of locations. One unit that stands out for immense storability is the Dewalt DWPW2100. Everything needed to perform a proper pressure washing is contained within its 23-inch-high, 10-inch-long, and 15-inch-wide square, durable body, which takes up only 2 cubic feet. All accouterments can be constructed for the job and then packed neatly away into this innovative pressure washer design.
By packing all necessary parts into its rectangular body, the Dewalt DWPW2100 is by far one of our favorite designs.
Before concluding our portability metric, we needed to understand how all these units fared when loading, unloading, pushing, pulling, or washing down a subject. Therefore, we looked at wheel size, build, clearance, and mobility. Gas washers were again large and unwieldy when it came to loading and unloading, but they do have properly sized wheels and reasonable ergonomics, which proved helpful once we began to move around.
It's essential to consider the type of tasks you will be doing, as some models can be carried, while others require some muscle to maneuver.
One of the heaviest electric units we tested is the Greenworks GPW3002, and as soon as we pushed and pulled it around, we realized how clunky and uncomfortable this thing was despite being equipped with large 10-inch wheels and having the most clearance out of our entire lineup. Less weight doesn't necessarily mean more ease of mobility, and we found ourselves struggling with the poor ergonomics of the LWQ S5. It is built at an awkward height that didn't fit any of our testers, and we had to constantly pick it up to move around. It is always highly recommended to evaluate your storage options, the type of tasks you will be working on, and the kind of terrain you will be working in before choosing a pressure washer.
Different sizes and types of wheels can either enhance or hinder your experience with a pressure washer.
Noise
Noise is a common byproduct of many household yard tools, and none of these machines are silent while in use. For this reason, we have allotted 15% of the total tally to our Noise metric.
To accurately survey the noise emissions of each pressure washer, we ran all machines at full throttle and used a Professional sound meter (SPL) to take decibel (dBA) readings from two data points. Measurement locations were directly next to each machine and at a distance of 25 feet away. Because a sound meter cannot account for or read squeals, whines, grinds, or variations in pitch, we supplemented our dBA findings with our own subjective observations after conducting hours of hands-on trials.
Our SPL shows 93 dBA, which, in our opinion, is a bit too loud.
Credit: Abriah Wofford
Most of the tested machines' noise emissions hovered around 80 decibels, but the gas-powered Simpson CM61083 emitted a particularly loud 93 decibels, topping our charts. It's also worth mentioning that with any gas-powered models, the engines do not shut off, even when the spray wand isn't in use; therefore, there's no respite from the constant drone of an internal combustion engine.
Surprisingly, the electric Greenworks GPW3002 proved to have the same constant noise emission problem by continually running and even becoming louder when depressing the wand's trigger. In spite of this, it did not pour out readings nearly as high as the Westinghouse ePX3500's 83.3 decibels or Dewalt DWPW2400's 84.8 decibels.
The quietest models we tested also proved to have some of the lowest PSI ratings, such as the Stanley 2150, which has a PSI rating of 1505 and a noise level of 73.3 dBA.
The Greenworks GPW3002 wasn't terribly loud on our SPL, but it creates some annoyance by constantly running even when the sprayer is not in use.

Ease of Use
Most pressure washers are relatively simple machines. However, there is enough variation in design that can either transform a good washer into a great one or vice versa, an average machine into a headache. Depending on the manufacturer, these features can vary significantly, so we assign a 15% Ease of Use metric weight to final scores. We got down to work right out of the box, assessing assembly time, hose connections, hose and cord organization, nozzles, intuitive storage for all accessories, and stability while in use.
The Craftsman CMEPW2400 received our highest score through its thoughtful design, which made every task just a bit smoother compared to other machines. There is ample room around the water inlet for no-fuss access, and a dedicated storage caddy is provided for five included nozzles beneath the handle. The 35.5" power cord wraps around a molded depression on the back of the washer, and a hook above it allows the 25.7" hose to coil around. The wand slides into a secure slot by the handle, and a detachable soap dispenser easily pops in and out of the main washer for filling and cleaning.
The length of their cords can limit the mobility of electric washers. At over 35 feet, the Craftsman allows for one of the largest ranges in our tests.

When testing pressure washers, a key feature we always examine is hose connections. The SunJoe SPX3000, Westinghouse ePX3500, and Greenworks GPW3002 come equipped with a garden hose hookup that is front and center on the machines, making them simple to hook up. The Stanley and both DeWALT product options also have roomy designs that make attaching your water inlet a breeze.
Inlet location can significantly impact the experience of a pressure washer for both good and bad reasons, but we prefer up-front, easy access.
We did find that the LWQ S5, in particular, has a major design flaw that warrants consideration before purchase. The hose inlet connection is located very close to the ground. After top-to-bottom testing, we noticed that both the connection port and water hose were being worn down and degraded due to contact with the ground when moving the machine around a job site. Unfortunately for the LWQ, it also took by far the longest to assemble right out of the box, further lowering its score in this metric. It is important to note at this time that all other units reviewed require some assembly.

Though they may not hinder job performance, unruly hoses and cords are always frustrating to deal with when trying to focus on completing your job or packing up when finished. The Greenworks GPW3002 has spectacular hose and cord storage, complete with rotating hooks for the power cord and a dedicated bungee system to secure the hose on its hook. The Stanley SHP2150 also supplies a hose hook on the back and a dual hook situation for the power cord, one of which pivots to facilitate easy unwinding.
With thoughtfully designed cord and hose organization, the Greenworks is one of the easiest models to roll up and put away.

Amongst the electric models, we found that there was a lot to be desired, except for the Dewalt DWPW2100. This impressive design stores everything inside of its square and rugged frame, allowing for a sleek and finished look when properly put away. Additionally, all other models feature relatively generic and straightforward hook-and-wrap systems for storing cords and hoses.

Hose and cord length can mean the difference between needing extra hoses and extension cords or not. All of these tested tools have hoses spanning a range of 20-26.5 feet and cords reaching 30-36 feet, except for one, the LWQ S5. If you're looking for a large radius of mobility, then this may not be your first pick, with a limited 19-foot power supply and only 16.5 feet of hose. We have charted the cord and hose lengths below.

Almost every pressure washer came equipped with a myriad of different angled attachments, some form of soap nozzle or dispenser, all with storage locations-- whether integrated into the body or as a separate accessory. The Stanley SHP2150 and Craftsman CMEPW2400 come equipped with onboard soap dispensers, while the LWQ S5 includes a handy foam cannon. Most reservoirs were straightforward to fill, but when we went to top off the Westinghouse ePX3500's tank, we found it on the back at a 45-degree angle, making for a messy fill-up. On the other side of the coin, the Craftsman's dispenser pops out for ultra-easy use.

The SunJoe SPX3000 has two onboard tanks, each equipped with a selection knob located near the handle. Some models lack a soap dispenser and instead feature a siphon hose for a direct draw from your desired container, such as the gas-powered Simpson CM61083. This is good for individuals who don't want to constantly stop to top off an onboard tank or a small bottle on the wand like the LWQ S5.
Extra cleaning features, such as a soap sprayer and multiple nozzles, are always helpful when tackling a thorough washdown.
How To Pick The Best Pressure Washer For You
When deciding on the type of pressure washer to purchase, several crucial elements should be considered. Investing in yard appliances like this can be confusing or downright daunting for a first-time buyer, but don't worry too much; our team of testers has got you covered. Below are a few key points from our complete [Pressure Washer Buying Advice | Pressure Washer Buying Advice Review] article.
Choosing the Right Model
First, assess which types of tasks you aim to tackle. Are you seeking raw power? Then, look at a gas-fueled unit or a high-powered electric washer. Do you just want to wash your vehicle? Then, take a look at something with multiple nozzles and a soap reservoir. It is also important to note what type of materials you may be washing. If you're trying to peel off exterior, residential, or commercial paint, choose power over size, which brings us to our next issue: size, weight, and portability. You always want to select a model that serves your needs. A lightweight and compact model can be thrown into the boot of a car or stored on a shelf, whereas a huskier machine will occupy more floor space and may not always be easy to lift. Another factor is where you intend to use your new machine. Many electric models come as small rolling units that perform well on concrete or asphalt, but once introduced to any uneven terrain, they can be out of place. That's why you might want to choose a machine with large tires, an ergonomic design, and/or a heavy-duty frame. That said, with more brawn comes more weight and less ease when loading or storing. The final element we all need to contemplate is noise. While all of these machines emit sound during use, some are louder than others. We recommend using ear protection for all of them during extended use. However, remember that electric pressure washers are generally quieter than gas models, and most of their motors shut off when you aren't actively spraying.
Electric Or Gas Powered
Anyone who has small home tasks to accomplish should purchase a corded electric pressure washer. They require very little maintenance, are simple and easy to operate and start, and generally offer plenty of cleaning power for day-to-day tasks. Corded washers are usually more affordable, but they require an additional power source and may necessitate the use of a long extension cord for certain tasks. Gas pressure washers are a different beast altogether. They are ideal for larger jobs and often have more power to scrub grittier assignments, but there's a caveat: a larger price tag. They also require routine annual maintenance, including but not limited to changing filters, oil, and regular gas fill-ups, and can be more challenging to start on colder days.
We hope our comprehensive review helps you find a perfect pressure washer for your needs.
