WEN PW31C Pressure Washer Cover Review: The Ultimate Armor for Your Machine?

There’s a certain satisfaction that comes from blasting away a winter’s worth of grime from the driveway or stripping old, flaking paint from a fence in mere minutes. A pressure washer is a tool of transformation, a powerful ally in the battle against dirt and decay. But what happens to this ally when the work is done? I learned this lesson the hard way a few years ago. After a long weekend of projects, I left my trusty gas pressure washer on the covered patio, thinking it was safe. A week of unexpected, driving rain and high humidity proved me wrong. When I went to start it for the next job, the pull-cord was stiff, rust spots were blooming on the frame welds, and the engine sputtered reluctantly. The sun-facing side’s plastic housing had already begun to fade. It was a stark reminder that these powerful machines, for all their ruggedness, are vulnerable. Failing to protect a several-hundred-dollar piece of equipment from sun, rain, dust, and debris isn’t just neglect; it’s throwing money away and shortening the life of a vital tool. A simple cover could have prevented it all.

What to Consider Before Buying a Pressure Washer Cover

A pressure washer cover is more than just a simple tarp; it’s a key solution for preserving the performance, appearance, and longevity of your equipment. It acts as a shield against the elements that conspire to degrade your machine. UV rays from the sun can make plastic components brittle and cause fading, rain can lead to rust on metal parts and water damage to sensitive engine components, and dust and pollen can clog air intakes and coat the entire unit in a layer of abrasive grime. A quality cover mitigates all these risks, ensuring your pressure washer is clean, protected, and ready to start when you need it most. Investing in a good cover is one of the most cost-effective maintenance steps you can take.

The ideal customer for this type of product is any pressure washer owner who stores their machine in a garage, shed, carport, or even outdoors on a covered patio. If your storage area is exposed to dust, moisture, temperature fluctuations, or sunlight, a cover is essential. It’s particularly crucial for those living in regions with harsh weather—be it intense sun, heavy rain, or snowy winters. Conversely, if you store your pressure washer in a climate-controlled, perfectly clean indoor space and never move it, a cover might be less critical. For those needing to protect their machine during transport in an open truck bed, a secure cover like the WEN PW31C Pressure Washer Cover is an invaluable asset.

Before investing, consider these crucial points in detail:

  • Dimensions & Fit: A cover is useless if it doesn’t fit. Measure your pressure washer’s length, width, and height, including the handle and any protruding parts like the hose reel. Look for a cover with dimensions slightly larger than your machine for easy application, but ensure it has features like an elastic hem or drawstring to cinch it tight and prevent it from becoming a sail in the wind.
  • Weather Resistance & Performance: The primary job of a cover is protection. Look for materials explicitly rated as waterproof or water-resistant, not just “weather-proof.” Equally important is UV resistance, which prevents the cover itself from degrading and cracking under sun exposure, ensuring it lasts for multiple seasons.
  • Materials & Durability: A cheap, thin plastic cover might last a single season, if you’re lucky. A superior cover, like the one we’re reviewing today, features a multi-layer construction. A tough, durable exterior like heavy-duty vinyl resists tears and abrasions, while a soft, non-abrasive interior lining (such as cotton or felt) protects your machine’s paint and plastic from scratches and scuffs during application and removal.
  • Ease of Use & Maintenance: The best cover is one you’ll actually use. It should be lightweight enough to handle easily but substantial enough to feel protective. Features like a full elastic-banded base and a drawstring with a toggle make securing the cover a matter of seconds. For maintenance, a simple wipe-down with a damp cloth should be all that’s needed to keep it clean.

Investing a small amount in a high-quality cover ensures your much larger investment in a pressure washer remains protected and functional for years to come.

While the WEN PW31C Pressure Washer Cover is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Look: Unboxing the WEN PW31C Pressure Washer Cover

Pulling the WEN PW31C Pressure Washer Cover from its packaging, the first thing we noticed was its surprising heft. Tipping the scales at 1.2 pounds, this is no flimsy, glorified trash bag. The material feels substantial and thick, a heavy-gauge vinyl that immediately inspires confidence. The exterior has a slight texture to it, suggesting a durable, weather-resistant finish. But the real surprise came when we turned it inside out. The interior is lined with a soft, black cotton material, almost like a thin felt. This is a premium touch we frankly didn’t expect at this price point. It’s a feature designed to prevent the very scratches and scuffs that cheaper, unlined covers can cause. There’s no assembly required, of course. We simply unfolded it, noting the sturdy stitching along the seams and the integrated elastic hem that runs the entire circumference of the base. The added drawstring and toggle feel robust, not like an afterthought. Our initial impression is that WEN has seriously over-engineered this cover in the best way possible, offering a product that feels more durable and thoughtfully designed than many covers that cost twice as much. You can see its full specifications and details here.

Key Benefits

  • Exceptionally thick, heavy-duty vinyl material provides robust protection.
  • Soft cotton interior lining prevents scratches on the machine’s finish.
  • Generous universal dimensions fit a wide range of pressure washer brands and sizes.
  • Elastic hem and drawstring ensure a secure, wind-resistant fit.

Potential Drawbacks

  • Isolated reports of weak stitching or seams tearing upon arrival.
  • May be overly large for very compact, small electric pressure washers.

Deep Dive: Performance Under Pressure (and Sun, and Rain)

A cover’s true worth is proven not on a shelf, but over months of exposure in a dusty garage or a weather-beaten carport. We put the WEN PW31C Pressure Washer Cover through its paces, focusing on the three pillars of a great cover: the material and construction, the universality of its fit, and its practical, day-to-day performance in protecting our valuable equipment.

Built to Last: A Closer Look at its Dual-Layer Armor

The standout feature of the WEN PW31C Pressure Washer Cover is, without a doubt, its material composition. The exterior is crafted from a UV and water-resistant vinyl that feels leagues ahead of the thin, crinkly materials found on budget covers. During our testing, we draped it over our test unit and subjected it to a direct, heavy spray from a garden hose, simulating a downpour. Water beaded up and rolled right off, with no signs of soaking through or leakage at the seams. The black color and UV-resistant treatment are crucial for outdoor storage, designed to fight the relentless sun damage that can fade paint and degrade plastic housings over time. While only a full season of sun will tell the final tale, the material’s thickness suggests it will resist cracking and deterioration far longer than lesser covers. Many users have confirmed this, with one noting, “The cover material appears to be very tough and thick and in my estimation would hold over well outside for several years.”

However, the protective genius of this design lies on the inside. The soft cotton lining is a game-changer. Anyone who has used a standard, unlined tarp knows that dragging it across a painted or plastic surface can leave behind fine scratches and scuffs. The WEN cover’s lining glides smoothly over the machine, protecting the finish like a polishing cloth. This dual-layer approach demonstrates a deep understanding of what equipment owners truly need: not just protection from the elements, but protection from the protector itself. It’s this attention to detail that elevates the WEN PW31C Pressure Washer Cover from a simple accessory to an essential piece of maintenance gear. It’s a feature multiple users celebrated, with one stating, “It’s pretty thick the inside of the tarp is soft with the outer part weather resistant.” This two-pronged defense system is the core of its value.

The “Universal” Promise Put to the Test: Fit and Adjustability

WEN markets this cover as “universal,” designed for their own PW31 model but suitable for any machine up to 23″ L x 20.5″ W x 39″ H. This is a bold claim, as pressure washers come in a staggering variety of shapes and sizes. We found this claim to be impressively accurate. We tested the fit on three different styles of machines: a tall, upright gas-powered DeWalt, a mid-sized Craftsman, and a much smaller, compact electric Sun Joe. On the large DeWalt, the cover was a perfect, snug fit, reaching all the way down to the floor and completely enveloping the wheels and handle, just as one user reported with their “Dewalt 3600 professional power washer.” On the mid-sized Craftsman, there was a bit more room, but this is where the design’s cleverness shines. The elastic-banded base naturally gathered the excess material around the bottom, and a quick pull on the drawstring cinched it tight, creating a custom-like fit that prevented any looseness.

The biggest surprise was the small electric Sun Joe. We expected the cover to completely swamp it, looking sloppy and ill-fitting. While it was certainly loose, one user’s experience mirrored our own perfectly: “I figured this thing would swamp our little sun Joe pressure washer but it fits great. Sure it’s a little loose but the washer is on the small end. The elastic at the bottom still makes for a snug fit.” The elastic hem and drawstring are not just features; they are the mechanism that makes the “universal” claim a reality. This adaptability is a massive selling point, giving buyers confidence that this one cover will likely fit their current machine and any future upgrades. This impressive versatility makes it a standout option, and you can check the exact dimensions and compatibility for yourself.

Everyday Usability and Long-Term Protection

Beyond material and fit, a cover has to be practical for everyday use. The WEN PW31C Pressure Washer Cover scores high marks here. It’s easy to throw over the machine after use, and the elastic hem helps guide it into place. The drawstring toggle is simple to operate and holds tension well, which is critical for outdoor storage in windy conditions. As one owner in a blustery area noted, “The tie cord at the bottom is a nice touch as with the winds in this area its very likely the cover would ballon up.” This simple feature provides peace of mind that you won’t find your cover in a neighbor’s yard after a storm. It effectively turns your pressure washer into a self-contained, protected unit, keeping it free from dust, cobwebs, and moisture.

However, no product is perfect. In our research, we came across an important piece of user feedback regarding durability. One user reported, “I was extremely satisfied with this cover until I discovered a tear in one of the seams… it tears at the seams so easily.” While the overwhelming majority of feedback praises the cover’s robust build, this indicates a potential for isolated quality control issues with the stitching. The vinyl itself is tough, but a weak seam can undermine the entire product. We inspected our unit’s seams closely and found them to be well-reinforced, but we recommend that any buyer give the seams a thorough check upon arrival. Despite this isolated concern, the overall package offers incredible long-term protective value, keeping your machine in prime condition and ready for action at a moment’s notice. For the price, the level of protection offered is truly hard to beat, making the WEN PW31C Pressure Washer Cover a smart buy.

What Other Users Are Saying

Across the board, the sentiment for the WEN PW31C Pressure Washer Cover is overwhelmingly positive. The most frequently praised attribute is the sheer quality of the material. One user sums it up perfectly, stating, “Cover material is very very thick, nothing sheer or thin here. Fantastic value for money.” This is echoed by another who was pleased with the fit on a larger machine: “I have a DeWalt 4000 psi pressure washer . And it covered it great better then I was expecting tbh.” The universal fit is another major point of satisfaction, with owners of Simpson, Husqvarna, Greenworks, and Powerhorse models all reporting excellent results.

The thoughtful design touches do not go unnoticed. The soft inner lining is a consistent highlight, with one customer noting, “This is a heavy cover with a felted lining that will keep my pressure washer clean and out of the elements.” However, the feedback isn’t universally perfect. The most significant criticism comes from a user who experienced a manufacturing defect: “It’s a shame that the seams are so fragile because the cover is made out of a thick, strong material… My cover arrived with a tear in one of the main seams.” While this appears to be a rare occurrence, it serves as a valid caution to inspect the product upon delivery. Overall, though, the consensus is clear: this cover delivers premium-level protection and build quality at a budget-friendly price point.

How the WEN PW31C Pressure Washer Cover Compares to the Alternatives

While the WEN PW31C Pressure Washer Cover is an accessory designed to protect your investment, it’s helpful to see it in the context of the pressure washing ecosystem. The alternatives here are not other covers, but the machines and components it is designed to work with or protect, offering a different perspective on where to allocate your budget.

1. DEWALT DWPW2100 2100PSI Washer

Dewalt Washer PRS WTR 2100PSI 1.2GPM DWPW2100
  • Dewalt WASHER PRS WTR 2100PSI 1.2GPM DWPW2100

The DEWALT DWPW2100 is a powerful and compact electric pressure washer. Comparing it to the WEN cover is a matter of “protect vs. purchase.” If you have a larger, more powerful gas machine, the WEN cover is a small, essential expense to protect that bigger investment. However, if your current machine is old or failing, you might consider forgoing the cover and putting that money towards a new, reliable unit like this DEWALT. It’s ideal for homeowners with medium-duty tasks like cleaning cars, patios, and siding. For owners of this DEWALT, the WEN cover would be an excellent, albeit slightly roomy, choice to keep it pristine.

2. DEWALT 3300 PSI Gas Pressure Washer

This DEWALT 3300 PSI model represents a significant investment in cleaning power. It’s a professional-grade gas machine designed for tough, demanding jobs. In this context, the WEN PW31C Pressure Washer Cover is not an alternative but a mandatory companion piece. When you spend this much on a high-performance engine and pump, leaving it exposed to the elements is simply not an option. The WEN cover’s heavy-duty construction and large dimensions are perfectly suited to protect a substantial machine like this, making it one of the most cost-effective insurance policies you can buy for your high-end equipment.

The RIDGE WASHER gun is an upgrade accessory that enhances the performance and ergonomics of your existing pressure washer. This highlights another angle: do you invest in protecting the machine’s body or in upgrading its functional components? The WEN cover protects the core unit—the engine, pump, and frame—from environmental damage. The RIDGE WASHER gun improves your user experience and cleaning efficiency. The ideal approach is to do both. First, protect the foundational investment with the WEN PW31C Pressure Washer Cover, then enhance its capabilities with upgrades like a high-quality spray gun.

Our Final Verdict: Is the WEN PW31C the Right Cover for You?

After extensive evaluation, we can confidently say that the WEN PW31C Pressure Washer Cover is a standout product that delivers exceptional value. Its greatest strengths are its robust, dual-layer construction—featuring a thick waterproof vinyl exterior and a scratch-proof cotton interior—and its truly universal fit that accommodates a vast array of machine sizes thanks to its smart elastic and drawstring design. For a surprisingly modest price, it provides the kind of heavy-duty protection you would expect from a far more expensive, custom-fit cover. It’s the perfect solution for any owner who stores their pressure washer in a less-than-perfect environment and wants to safeguard their investment against the slow decay of sun, rain, and dust.

While we noted an isolated user report of a torn seam, the overwhelming evidence points to a well-made and durable product. We recommend it to virtually any pressure washer owner, from the weekend warrior with a compact electric model to the professional with a heavy-duty gas machine. It’s a small price to pay for the peace of mind that comes with knowing your equipment is shielded and ready for the next job. If you’re looking for an affordable, high-quality, and versatile protective solution, you will not be disappointed with the WEN PW31C Pressure Washer Cover.
