6 Best Pressure Washer Covers for Outdoor Storage
Shield your pressure washer from harsh outdoor elements. A quality cover is a simple way to prevent rust and costly repairs. We review the top 6 models.
You finish cleaning the chicken coop, roll your pressure washer back to the side of the barn, and forget about it until next month. When you go to start it, the pull cord is stiff, the engine sputters, and you spot a mouse nest tucked beside the carburetor. A simple, inexpensive pressure washer cover could have prevented this entire headache. Investing in the right cover isn’t about keeping your equipment looking new; it’s about making sure it works when you need it.

Why Your Pressure Washer Needs a Quality Cover
Leaving a pressure washer exposed to the elements is a recipe for costly, frustrating repairs. Rain seeps into electrical components on electric models and fouls the fuel and air filters on gas engines. Even a little moisture can lead to a rusted pump or a seized motor, turning a reliable tool into a heavy paperweight.
The sun is just as damaging. UV rays degrade plastic housings, making them brittle and prone to cracking. More importantly, they break down the rubber in your high-pressure hose and O-rings, leading to dangerous leaks and a loss of pressure right when you’re trying to blast mud off the tractor.
Don’t forget about pests, either. Mice and other rodents love to chew through wiring for nesting material, and spiders will happily build webs inside exhaust ports and air intakes. A good cover creates a physical barrier that deters these critters, saving you from a repair bill that will far exceed the cost of the cover itself. It’s the cheapest insurance policy you can buy for your machine.
Classic Accessories Ravenna: Heavy-Duty Protection
When you need a cover that feels more like armor, the Classic Accessories Ravenna is the one to get. This isn’t a flimsy piece of plastic; it’s made from a heavy-duty, Gardelle One woven polyester fabric that resists tearing and cracking, even after years in the sun and cold. If your machine is stored in a spot that gets hit with wind, rain, and direct sun, this is your best defense.
What sets the Ravenna apart are the thoughtful features. It has padded handles that make taking it on and off easy, which you’ll appreciate when your hands are cold and muddy. It also includes built-in air vents that let moisture escape, preventing the condensation that can lead to rust, while a mesh barrier keeps bugs out.
The secure fit is another major advantage. An elastic hem cord and adjustable buckle straps ensure the cover stays put during a serious storm, rather than ending up in your neighbor’s pasture. While it costs more than some other options, the Ravenna’s durability means you buy it once and you’re done. It’s an investment in long-term, worry-free protection.
Himal Outdoors Cover: Best for All-Weather Use
The Himal Outdoors cover strikes an excellent balance between durability and price, making it a fantastic all-around choice for most hobby farm situations. It’s typically constructed from 600D polyester fabric with a waterproof backing, which is more than enough to handle heavy downpours, snow, and intense sun without degrading.
This cover is designed for practicality. It features a simple but effective drawstring at the bottom, allowing you to cinch it tight around the base of your pressure washer. This snug fit is crucial for keeping out wind-blown dust, debris, and curious critters looking for a home. It’s a no-fuss design that just works.
Think of the Himal as the reliable workhorse of pressure washer covers. It may not have all the premium features of more expensive models, but it delivers on its core promise: keeping your machine dry and protected season after season. For the price, its weather resistance and sturdy construction are hard to beat.
Sun Joe SPX-PCV1: A Custom Fit for SPX Models
If you own a Sun Joe electric pressure washer from the popular SPX series, stop looking at universal covers. The SPX-PCV1 is made by the manufacturer specifically for these models, and the difference a custom fit makes is immediately obvious. There’s no excess material to flap in the wind or collect pools of rainwater.
A tailored cover provides superior protection because it leaves no gaps. It fits snugly over the unique shape of the SPX units, including the handle, hose reel, and wand holder. This prevents wind from getting underneath and turning the cover into a sail, and it ensures every part of the machine is shielded from UV rays and moisture.
The only real downside is its specificity. This cover is useless if you have a different brand or even a different Sun Joe model. But for SPX owners, it’s the most effective way to protect your investment. You get a clean look and the peace of mind that comes from knowing your cover was designed precisely for your machine.
iCOVER Universal Fit: Great Value and Versatility
The iCOVER is the go-to option when you need a solid, affordable cover that fits a wide range of machines. Whether you have an older model with an odd shape or just want a dependable cover without spending a lot, this one gets the job done. It’s a practical, budget-conscious solution.
Made from a lighter-weight polyester fabric, it still provides good protection against rain, dust, and UV damage. Its main advantage is the elastic hem cord that provides a flexible, snug fit on various pressure washer sizes and configurations. You don’t have to worry about taking precise measurements; it’s designed to adapt.
The tradeoff for its versatility and low price is durability. It won’t stand up to the same level of abuse as a heavy-duty 600D fabric cover, especially in consistently harsh weather. However, for a pressure washer stored under a porch, in a lean-to, or in a less exposed area, the iCOVER provides more than enough protection for the money.
ToughCover Premium for Gas-Powered Washers
Gas-powered pressure washers are bigger, heavier, and have more complex parts to protect than their electric counterparts. The ToughCover is built with these machines in mind. Its heavy-duty, tear-resistant material is designed to withstand the sharp corners of a metal frame and engine block without ripping.
This cover is sized generously to accommodate the larger footprint of gas models, including the wheels, handle, and engine housing. It often includes buckle straps that can be secured around the frame or wheels, ensuring that even a large cover won’t be blown off in a strong gust of wind. This is critical, as the larger surface area of these covers can easily catch the wind.
Protecting a gas engine is about more than just keeping rain off. You need to shield the air filter, spark plug, and carburetor from moisture and debris. The ToughCover provides the robust, full-coverage protection necessary to ensure your engine starts reliably every time you need it.
GYUEM Vented Cover: Prevents Moisture Buildup
One of the biggest mistakes is thinking any waterproof cover will do. A non-vented cover can trap moisture from condensation, creating a humid microclimate around your machine. The GYUEM cover solves this problem with strategically placed air vents.
These vents, often covered by a fabric flap to keep rain out, allow air to circulate freely. This is especially important in climates with high humidity or significant temperature swings from day to night. As the air cools, moisture condenses on metal surfaces; without ventilation, that moisture stays trapped, promoting rust on the pump and frame and corrosion on electrical contacts.
By allowing your pressure washer to "breathe," a vented cover actively prevents the slow, silent damage caused by trapped humidity. It’s a small feature that makes a huge difference in the long-term health of your machine, particularly for the sensitive components of the engine and pump.
Key Features in a Pressure Washer Storage Cover
When choosing a cover, the "best" one depends entirely on your machine and where you store it. Don’t just grab the cheapest option; focus on the features that matter for your situation. A few key elements will determine how well a cover performs and how long it lasts.
Here are the most important factors to consider:
- Material and Durability: Look for the fabric density, measured in Denier (D). A 600D polyester cover is significantly more tear-resistant and durable than a 210D one. For full sun exposure, make sure it has a UV-protective coating.
- Waterproofing: A "water-resistant" cover will shed a light shower, but a truly waterproof one will have a PVC or polyurethane backing and taped seams to withstand a downpour.
- Secure Fit: A cover is useless if it blows away. Look for an elastic hem, a drawstring cord, or, even better, buckle straps that physically attach to the machine’s frame or wheels.
- Vents: As mentioned, vents are non-negotiable for preventing rust-causing condensation. Ensure any cover you buy for long-term outdoor storage has them.
Think about your storage location. If the pressure washer sits under a covered carport, a lighter, water-resistant cover might be sufficient to protect it from dust and ambient moisture. But if it’s sitting out by the barn with no overhead protection, you need a heavy-duty, waterproof, UV-resistant, and securely strapped cover. Match the cover to the conditions, and your machine will thank you.
Your pressure washer is a powerful tool that saves you countless hours of scrubbing. Protecting it with a proper cover is a small, simple task that prevents big, expensive problems. For less than the cost of a new hose, you can ensure your machine is clean, dry, and ready to fire up the moment you need it.
