Flow Rate and Pressure Showdown
Flow Rate
The Greenworks unit delivers a maximum flow rate of 2.3 GPM, while the Sun Joe model provides 1.2 GPM. Higher flow rates rinse away debris faster and cover larger areas more efficiently. The Greenworks model also features Jettflow Technology, which claims to deliver up to 50% more flow for reaching higher areas. This significant difference in water volume means the Greenworks cleans quicker on big jobs like driveways or siding. The Sun Joe’s lower flow rate suits smaller, delicate tasks where excessive water might be wasteful or damaging.
Maximum Pressure
Pressure determines how well the machine blasts away stuck-on grime. The Greenworks pressure washer generates 2700 PSI, whereas the Sun Joe model produces 1600 PSI. The higher PSI on the Greenworks unit allows it to tackle tougher stains, such as oil spots on concrete or thick algae on decks. The Sun Joe’s 1600 PSI is sufficient for lighter duties like rinsing cars or washing patio furniture. If your primary need is removing heavy dirt, the higher pressure rating of the Greenworks model offers a clear advantage in cleaning power.
Weight and Portability
Weight affects how easy it is to move the machine around your property. The Sun Joe model weighs only 11.7 pounds, making it very lightweight and easy to carry up stairs or store in a small closet. The Greenworks model weighs 50.7 pounds due to its cast aluminum pump and larger frame. While the Greenworks is heavier, it offers more power. If you need to move the washer frequently or have limited storage space, the Sun Joe’s compact and light design is much more practical for everyday handling.
Hose Length
The length of the high-pressure hose determines how far you can reach without moving the unit itself. The Sun Joe model comes with a 20-foot high-pressure hose. The Greenworks model does not list a specific hose length in the provided data. A longer hose generally provides more flexibility and reach. With the Sun Joe’s 20-foot hose, you can clean areas slightly further from the power source. However, the lack of specified hose length for the Greenworks unit makes a direct comparison on this specific feature incomplete based on the available specifications.
Motor Technology
The type of motor impacts efficiency and durability. The Sun Joe model uses a standard 13-amp electric motor. The Greenworks model features a brushless motor with TruBrushless Motor Technology. This brushless design automatically adapts motor power for maximum cleaning efficiency with any nozzle. Brushless motors typically last longer and require less maintenance than brushed motors because they have fewer worn parts. This technological difference suggests the Greenworks unit may offer better long-term reliability and more consistent power delivery during extended use.
Which Pressure Washer Fits Your Needs

The cast aluminum pump ensures durability during demanding residential cleaning projects.
Those wanting faster rinsing and higher power
Higher flow rate means quicker rinsing for large surfaces. The 2.3 GPM max flow clears debris efficiently. Combined with 2700 PSI, this unit outperforms lower-spec models. The push-button start simplifies operation. You gain better cleaning power than standard 1600 PSI units. This model suits those who prioritize speed and deep cleaning capability.
