Ryobi vs Sun-Joe Cordless Pressure Washer

Ryobi vs Sun-Joe Cordless Pressure Washer: Which One Should You Buy?

Both Ryobi and Sun-Joe offer cordless pressure washers that free you from the hose and outlet, but they target different buyer profiles. Ryobi leverages its massive ONE+ battery system, while Sun-Joe focuses on value with included batteries and a slightly higher flow rate. Here is how they compare across the factors that matter most.

Battery Ecosystem and Power

The Ryobi 18V ONE+ HP Brushless Pressure Washer runs on Ryobi's 18V platform, which powers over 280 tools. If you already own Ryobi tools, this is a no-brainer. The brushless motor delivers 600 PSI and 1.2 GPM, which is enough for cleaning cars, patio furniture, and light siding. Owners on retailer sites consistently report that runtime with a 4.0Ah battery is about 15-20 minutes of continuous use.

The Sun-Joe SPX1500 uses a proprietary 24V battery system. It comes with two 4.0Ah batteries and a charger in the box, so you can start cleaning immediately. It delivers 580 PSI and 1.1 GPM. While the PSI is slightly lower, the GPM is close. However, the brushed motor is less efficient than Ryobi's brushless unit, meaning shorter runtime per charge. Owner reviews note that the Sun-Joe batteries take about 5 hours to charge fully.

Build Quality and Portability

Ryobi's build quality is consistently rated higher by owners. The unit feels solid, with a metal wand and a robust hose connection. It weighs just 8.5 pounds, making it easy to carry around the property. Many users mention that the trigger lock mechanism feels durable and that the onboard storage for the wand and nozzle is well-designed.

The Sun-Joe SPX1500 is heavier at 10.2 pounds. The plastic housing feels less premium, and several owner reviews mention that the hose connection can feel loose over time. The telescoping handle and wheels are a nice touch for portability, but the overall build quality is not on the same level as the Ryobi. The Sun-Joe does include a 20-foot hose, which is longer than the Ryobi's 15-foot hose.

Cleaning Performance

For light to medium duty tasks, both units perform adequately. The Ryobi's brushless motor provides consistent pressure without bogging down. Owners report that it easily removes mud from tires, cleans patio slabs, and blasts away bird droppings from cars. The adjustable nozzle gives a good range from a wide fan to a concentrated stream.

The Sun-Joe SPX1500 also cleans well for its class. The included soap nozzle and two-in-one nozzle (fan and jet) are convenient. However, some owners note that the pressure drops noticeably when using the included foam cannon. The Sun-Joe is better suited for occasional use on smaller jobs, while the Ryobi feels more capable for regular weekly cleaning.

What to Check Before Buying a Cordless Pressure Washer

Before you buy, check your existing tool battery platform. If you own Ryobi 18V tools, the Ryobi pressure washer is the logical choice. If you are starting from scratch, consider that Ryobi's ecosystem is larger and more affordable for future tool purchases. Also, think about your typical cleaning tasks. For cars, bikes, and patio furniture, 600 PSI is sufficient. For heavy concrete cleaning or stripping paint, you will need a gas or corded electric model.

Mistakes to Avoid When Choosing a Cordless Pressure Washer

Do not assume higher PSI always means better cleaning. GPM (gallons per minute) is equally important for rinsing away dirt. A unit with high PSI but low GPM will struggle to clear debris. Also, avoid buying a pressure washer with a proprietary battery unless you are certain you will not need other tools. The cost of replacement batteries can add up quickly. Finally, do not underestimate the importance of runtime. A single 4.0Ah battery may only give you 15 minutes of actual cleaning time. Plan to buy an extra battery if you have a larger property.
