You’ve just spent the weekend scrubbing your driveway on your hands and knees, only to see the grime still clinging to the concrete. Or maybe your patio looks more like a moss garden than an outdoor living space. If that sounds familiar, it’s time to consider an electric pressure washer. But with two dominant brands, Sun Joe and Greenworks, how do you choose? This guide breaks down the key differences, top models, and accessories to help you decide which one fits your cleaning needs.
We’ve evaluated a range of Sun Joe and Greenworks products, from standalone pressure washers to surface cleaner attachments. Whether you’re a homeowner tackling routine maintenance or a DIY enthusiast with heavy-duty projects, we’ll help you navigate the options.

Buying Guide: What to Look For in an Electric Pressure Washer
Power and Performance
When comparing pressure washers, the two key numbers are PSI (pounds per square inch) and GPM (gallons per minute). PSI determines the spray force, while GPM affects how quickly you can clean. For most home tasks like driveways and patios, a unit with around 2000 PSI and 1.2 GPM is sufficient. The Sun Joe SPX3000 delivers up to 2030 PSI, making it a solid choice for medium-duty jobs. If you need more power, look for models with higher ratings, but remember that electric motors typically max out around 2000-2500 PSI.
For attachments, the PSI rating matters too. The Sun Joe SPX-SC14 universal surface cleaner handles up to 4000 PSI, so it’s future-proof if you ever upgrade to a gas model. The Greenworks 12-inch surface cleaner is compatible with most pressure washers, but always check the maximum pressure rating to avoid damage.
Portability and Ease of Use
Electric pressure washers are generally lighter than gas models, but weight still varies. The Sun Joe SPX100-GO weighs just over 14 pounds and features wheels and onboard storage, making it easy to move around your property. If you have a large yard, consider a model with a longer hose and cord. The Sun Joe SPX100-GO includes a 20-foot hose and 35-foot cord, giving you plenty of reach.
Surface cleaners are also designed for ease. The Sun Joe 10-inch multi-surface attachment is lightweight and impact-resistant, so you can maneuver it without fatigue. The Greenworks 11-inch surface cleaner is quick-connect compatible, meaning you can attach it in seconds.
Versatility and Accessories
Different jobs require different spray patterns. Look for a pressure washer that includes multiple nozzles. The Sun Joe SPX100-GO comes with four quick-connect nozzles (0°, 15°, 25°, 40°) and a foam cannon for detergent application. The Sun Joe SPX3000 goes further with five tips, including a soap nozzle. If you plan to clean cars, boats, or outdoor furniture, having a soap applicator is a game-changer.
Surface cleaner attachments are essential for large flat areas. The Sun Joe 10-inch model features dual nozzles for a streak-free finish, while the Greenworks 11-inch and 12-inch models are designed for quick-connect compatibility with most pressure washers. For heavy-duty use, the Sun Joe SPX-SC14 offers a wider 14-inch cleaning path and four wheels for stability.
Build Quality and Warranty
A pressure washer is an investment, so you want it to last. Look for models with stainless steel lances and brass fittings, like the Sun Joe SPX3000. The Sun Joe SPX-SC14 is made of stainless steel and can handle water temperatures up to 300°F, which is great for blasting away grease. Greenworks offers a 3-year warranty on their 12-inch surface cleaner, while Sun Joe provides a 2-year warranty on their pressure washers, extendable with registration.

Don’t forget about maintenance. The SPX3000 Pressure Washer O-Rings kit from KitchenKipper is a cheap insurance policy to keep your Sun Joe running smoothly. It includes multiple sizes to fit SPX3000 and other models.
Final Thoughts
Both Sun Joe and Greenworks offer excellent electric pressure washers and attachments, but the right choice depends on your specific needs. If you want a versatile, powerful standalone unit with a foam cannon and multiple nozzles, the Sun Joe SPX100-GO Electric Pressure Washer is a fantastic pick for most homeowners. For those tackling large flat surfaces, the Greenworks 11″ Surface Cleaner Universal Pressure attachment is a budget-friendly way to speed up your cleaning. Whichever you choose, you’ll be saying goodbye to manual scrubbing for good.
Frequently Asked Questions
Can I use a Greenworks surface cleaner on a Sun Joe pressure washer?
Yes, most Greenworks surface cleaners come with a 1/4-inch quick-connect fitting that is universal. As long as your Sun Joe pressure washer has a standard quick-connect adapter, you can attach a Greenworks surface cleaner. Just verify the PSI rating of the attachment is compatible with your machine’s output.
What is the best PSI for cleaning a driveway with an electric pressure washer?
For driveways, a pressure washer with at least 2000 PSI is recommended to remove stubborn stains, oil, and mildew. The Sun Joe SPX3000 delivers 2030 PSI, which is adequate for most concrete surfaces. Pair it with a surface cleaner attachment to cover large areas faster.
Are electric pressure washers as powerful as gas models?
No, gas pressure washers typically offer higher PSI and GPM, making them more powerful. However, electric models are lighter, quieter, and easier to maintain. For most residential tasks, an electric unit is more than sufficient. If you’re considering both, read our ryobi vs greenworks pressure washer comparison to see how they stack up.
How do I maintain my Sun Joe pressure washer?
Regular maintenance includes checking and replacing O-rings, cleaning the inlet filter, and flushing the system after each use. The KitchenKipper O-ring kit is a simple way to keep your connections leak-free. Also, store the unit in a dry place and use a pressure washer pump saver if you live in a freezing climate.
