Greenworks Pressure Washer Specs Compared
Maximum Pressure Output
The Greenworks 2000 PSI 1.2 GPM Electric Pressure Washer delivers 2000 PSI of cleaning force. This model is rated in accordance with PWMA standards, ensuring reliable performance for medium-duty tasks. In contrast, the Greenworks 1800 PSI Open Frame Pressure Washer provides 1800 PSI. Both units carry PWMA certification, which indicates they meet specific industry performance benchmarks. The 200 PSI difference gives the first model a slight advantage in tackling stubborn grime on concrete or decks. You will notice this power gap when cleaning heavily soiled surfaces, where the higher pressure helps break down dirt more effectively.
Flow Rate Performance
Both pressure washers operate at a flow rate of 1.2 GPM. This consistent water volume means both units are equally capable of rinsing away loosened debris quickly. The flow rate is a critical factor in determining how fast you can clean large areas like driveways or siding. Since the gallons per minute are identical, neither unit holds an advantage in terms of water throughput. You will find that both models require similar amounts of time to complete residential cleaning projects. The shared 1.2 GPM specification ensures that you get adequate water coverage regardless of which machine you choose for your outdoor maintenance needs.
Power Source and Motor
The Greenworks 2000 PSI model is powered by a 14 AMP electric motor. It features a push-button start and start/stop technology that automatically switches the motor off when the spray wand is not engaged. This feature helps save energy and extends the lifespan of the pump and motor. The Greenworks 1800 PSI Open Frame Pressure Washer is also an electric unit, but the data does not specify its amperage or if it includes automatic start/stop technology. The explicit mention of the 14 AMP motor and energy-saving features in the first model gives it a clear advantage in terms of user convenience and efficiency.
Built-in Soap Tank
The Greenworks 2000 PSI 1.2 GPM Electric Pressure Washer includes an on-board soap tank. This allows you to easily switch from pressure washing to using cleaning detergents by simply changing to the soap tip on the spray wand. The unit automatically draws detergent from the tank. The data for the Greenworks 1800 PSI Open Frame Pressure Washer does not mention a built-in soap tank. This means you would likely need to use a separate soap bottle or adapter for applying chemicals with the second model. The integrated tank in the first unit offers a more streamlined workflow for cleaning tasks that require detergents.
Physical Dimensions and Weight
Size and weight differ between the two units. The Greenworks 2000 PSI model measures 17.3 inches wide, 19.3 inches long, and 31.7 inches high, weighing 27.8 pounds. The Greenworks 1800 PSI Open Frame Pressure Washer is 19.7 inches wide, 13.6 inches long, and 31.7 inches high, weighing 23.2 pounds. Both share the same height. The first model is wider and longer but heavier. The second model is narrower and shorter but lighter. If you need a unit that is easier to lift or store in a tight space, the lighter, narrower frame of the second model may be preferable. However, the first model offers a more substantial build.
Which Greenworks Pressure Washer Fits You
Users needing maximum cleaning force
You should choose the 2000 PSI model if you tackle tougher grime. The extra 200 PSI provides more aggressive cleaning power for stubborn dirt on concrete or wood. Both units share the same 1.2 GPM flow rate, but the higher pressure makes a noticeable difference on medium-duty projects like cleaning vehicles or patio furniture.
Buyers prioritizing portability and compact size
Select the 1800 PSI Open Frame version for easier storage and handling. It weighs 23.2 pounds, which is 4.6 pounds lighter than the 2000 PSI model. Its length is also shorter at 13.6 inches compared to 19.3 inches. This compact design makes it ideal for users who need to move the unit frequently or store it in tight spaces.
Those wanting integrated soap application
The 2000 PSI model includes an onboard soap tank for convenient detergent use. You can switch to cleaning detergents by simply changing the spray wand tip. The unit automatically draws soap from the tank. This feature is not listed for the 1800 PSI Open Frame model, making the 2000 PSI unit better for tasks requiring chemical cleaning agents.
Shoppers seeking energy-efficient operation
Choose the 2000 PSI model for its start/stop technology. The motor switches off automatically when the spray wand is not engaged. This feature saves energy and extends the lifespan of the pump and motor. The 1800 PSI Open Frame does not list this specific energy-saving mechanism in its specifications, making the 2000 PSI model more efficient for intermittent use.
