Greenworks G40 Pressure Washer Specifications
Power Source and Battery Technology
The Greenworks G40 runs on a 40V lithium-ion battery system. This battery technology provides a stable power output and good runtime for cordless operation. The lithium-ion cells ensure that the battery charges quickly and retains power well over time. One of the main advantages of using a battery-powered system is the elimination of gas or electrical cords, making it safer and more convenient to use outdoors. The battery is also interchangeable with other Greenworks 40V tools, adding value for users who own multiple devices from the brand.
Pressure and Flow Rate Performance
This pressure washer delivers a maximum pressure of 1600 PSI, which is sufficient for most home cleaning tasks such as washing cars, patios, garden furniture, and bicycles. The flow rate of approximately 0.5 gallons per minute allows for controlled water use, making it efficient while cleaning. Although this pressure is lower than many gas-powered washers, the G40’s pressure and flow are well-balanced for safe cleaning without damaging delicate surfaces. This makes it a practical option for users who want good cleaning power without the risk of surface damage.
Weight and Portability
Weighing around 14 pounds, the Greenworks G40 is lightweight and easy to carry, even for extended periods. Its cordless design enhances portability by removing the need to stay near electrical outlets or manage tangled cords. This is particularly useful for outdoor cleaning in large areas or where power supply access is limited. The compact size and ergonomic handle design make transportation and storage hassle-free, appealing to homeowners who need a pressure washer they can quickly grab and use anywhere.
Spray Nozzle Options and Versatility
The Greenworks G40 comes equipped with multiple spray nozzle tips, including 0°, 15°, 25°, and 40° options. These nozzles allow users to switch between concentrated high-pressure streams for tough dirt and wider spray patterns for gentle rinsing. This flexibility makes the washer adaptable to a variety of cleaning tasks — from stubborn grime on concrete surfaces to delicate washing of car paint or garden tools. Changing the nozzles is simple and requires no special tools, making it easy to adjust water pressure on the fly.
Battery Life and Charging Time
The 40V battery typically provides 20 to 30 minutes of continuous use on a full charge, which covers most quick cleaning jobs. Depending on the intensity of use and pressure settings, actual runtime may vary. Charging the battery takes about 60 minutes using the standard charger. Users can purchase additional batteries if longer operating times are needed, which is especially useful for larger cleaning areas or extended work sessions. The battery system’s quick charge and decent runtime strike a balance between convenience and performance.
Water Tank Capacity and Usage
The G40 features a built-in 1.3-gallon water tank, allowing users to operate the washer without needing to connect to an external water source constantly. This tank size is suitable for small to medium jobs such as cleaning vehicles, outdoor furniture, or small patios. The integrated tank adds to the machine’s portability since you don’t need to drag hoses around, although a garden hose can be attached for longer use. This flexibility ensures the washer can be used in areas without easy access to water.
Benefits of Using the Greenworks G40 Pressure Washer
Eco-Friendly and Quiet Operation
One of the main benefits of the Greenworks G40 is its environmentally friendly operation. The battery-powered motor produces no direct emissions, unlike gas-powered pressure washers that emit fumes and pollutants. Additionally, the G40 runs much quieter, making it suitable for use in noise-sensitive neighborhoods or during early or late hours. This low noise level also reduces user fatigue and makes cleaning more pleasant, especially in confined spaces where sound tends to echo.
Ease of Use and Low Maintenance
The Greenworks G40 is designed with user convenience in mind. It requires minimal assembly, and there is no need to handle fuel, oil, or complicated engines. Starting the machine is as simple as pressing a button once the battery is inserted and charged. Maintenance is straightforward, mostly limited to cleaning the nozzles and periodically checking the water tank. Without a gas engine, users avoid regular engine tune-ups, oil changes, or fuel storage, saving time and reducing hassle.
Portability and Flexibility
Thanks to its cordless design and lightweight construction, the G40 offers exceptional portability compared to many other pressure washers. Users can clean cars parked far from the house, patios, fences, and even tools in the garden without worrying about cords or hoses. This freedom of movement makes the G40 ideal for users who need a pressure washer that works well in different settings. Its compact size also allows easy storage in small garages or sheds.
Safety Features for User Protection
The Greenworks G40 includes built-in safety features such as an automatic shut-off that activates when the trigger is released. This helps conserve battery life and prevents accidental water spraying. The pressure washer also uses durable materials and an ergonomic handle to provide a secure grip, reducing the risk of slips during operation. These safety elements make the washer suitable for a wide range of users, including those new to pressure washing.
Cost-Effectiveness Over Time
While the initial purchase price of the Greenworks G40 may be higher than some basic corded electric models, the long-term savings are significant. Users avoid ongoing costs related to gasoline, oil, engine repairs, and extensive maintenance. The efficient battery system also ensures that energy consumption is low. For people who want to invest in a pressure washer that lasts and costs less to run, the G40 offers a good balance between upfront expense and long-term value.
Versatility in Cleaning Applications
The Greenworks G40 is well-suited for a wide variety of cleaning tasks. It can effectively wash cars, remove dirt from patios and decks, clean garden furniture, and rinse outdoor tools and equipment. Its adjustable nozzles and moderate pressure ensure users can safely clean delicate surfaces without causing damage.
Comparison of Greenworks G40 with Other Pressure Washer Types
Battery-Powered vs Gas-Powered Pressure Washers
The Greenworks G40 is part of the growing category of battery-powered washers, which are valued for their quiet, clean operation and portability. Gas-powered washers typically offer higher pressure and longer run times but require more maintenance, produce noise, and emit pollutants. For users focused on convenience, environmental impact, and noise reduction, the G40 is often the better choice, especially for home use.
Corded Electric vs Cordless Battery Pressure Washers
Corded electric washers provide continuous power without concerns about battery life, but they limit user mobility due to the need for nearby outlets and extension cords. The Greenworks G40’s cordless design removes these limitations, allowing for cleaning in remote areas or places without electrical outlets. However, the trade-off is limited runtime per battery charge. Users who prioritize freedom of movement often prefer cordless models like the G40.
Positioning Among Pressure Washer Brands
Greenworks is recognized as a reliable brand within the pressure washer market, known for quality battery-powered models. Other notable brands include Ryobi, Sun Joe, and Karcher, each offering a range of washers with different features and price points. When choosing a pressure washer, it is important to consider your specific needs and compare features across brands.

Maintenance Tips for the Greenworks G40 Pressure Washer
Battery Maintenance
To maximize battery life, it is important to store the battery in a cool, dry place and avoid letting it drain completely before charging. Regular charging after use helps keep the battery healthy. If you do not plan to use the pressure washer for extended periods, remove the battery and store it separately.
Cleaning Nozzles and Filters
Clogged nozzles can reduce performance. Periodically inspect and clean the nozzles with a small tool or needle to remove debris. Also, check the water filter to ensure it is free of dirt and sediment, which can block water flow and strain the motor.
Water Tank Care
Empty the water tank after each use to prevent algae growth or sediment buildup. Rinse it thoroughly with clean water to keep it fresh and ready for the next use. This simple step helps avoid damage to the pressure washer’s internal components.
Proper Storage
Store the pressure washer in a dry, temperature-controlled environment away from direct sunlight and freezing temperatures. Protecting the machine from harsh conditions will prolong its lifespan and maintain optimal performance.
