Greenworks 1-Gallon Cordless Sprayer (G30)
Best for Small GardensPros
- Lightweight and easy to carry
- Adjustable nozzle for fine mist to stream
- Battery lasts for multiple tank fills
Cons
- Small tank requires refills for large areas
- Plastic wand feels less durable
The Greenworks 1-Gallon Cordless Sprayer is the ideal entry-level option for homeowners with small gardens or patios. It uses the G30 20V battery platform, which is shared with other Greenworks tools like trimmers and blowers. The adjustable nozzle allows you to switch from a fine mist for delicate plants to a direct stream for targeted weed killing.
Owner reviews consistently praise its ease of use and consistent pressure. The pump delivers a steady flow without the need for manual pumping. However, the 1-gallon tank means you will need to refill for larger jobs, and some users note the plastic wand could be sturdier. Overall, it is a reliable choice for basic garden spraying tasks.
Greenworks 2-Gallon Cordless Sprayer (G40)
Best for Large YardsPros
- Larger tank reduces refill frequency
- More powerful 40V battery
- Wider spray pattern for faster coverage
Cons
- Heavier when full
- Battery not compatible with G30 tools
The Greenworks 2-Gallon Cordless Sprayer is designed for larger properties where the 1-gallon model would require constant refills. It runs on the G40 40V battery platform, which provides more runtime and power for sustained spraying. The adjustable nozzle offers a wider fan pattern, making it quicker to cover lawns and garden beds.
Owner feedback highlights the consistent pressure and the convenience of the larger tank. The sprayer is comfortable to carry with a padded shoulder strap. However, the 40V battery is not compatible with Greenworks G30 tools, so you may need to invest in a separate battery system if you already own G30 tools. The unit is also heavier when full, which can be tiring for extended use.
Greenworks 4-Gallon Backpack Sprayer (G40)
Best for Heavy UsePros
- Large capacity for big jobs
- Backpack design distributes weight
- Long runtime with 40V battery
Cons
- Bulky and heavy when full
- Higher price point
The Greenworks 4-Gallon Backpack Sprayer is the heavy-duty option for users who need to cover large areas or have frequent spraying tasks. The backpack design helps distribute the weight across your shoulders, making it more comfortable than carrying a handheld unit. It uses the same G40 40V battery as the 2-gallon model, so batteries are interchangeable within that platform.
Reviews from owners indicate that the pump provides consistent pressure even when the tank is nearly empty. The adjustable nozzle and wand allow for precise application. However, the unit is bulky and can be heavy when fully loaded with 4 gallons of liquid. It is also the most expensive Greenworks sprayer, so it is best suited for serious gardeners or professionals who need the capacity.
Greenworks 1-Gallon Handheld Sprayer (G30)
Best Budget OptionPros
- Lowest price in the lineup
- Very lightweight
- Simple operation
Cons
- Fixed nozzle limits versatility
- Shorter runtime than adjustable models
The Greenworks 1-Gallon Handheld Sprayer is the most affordable option in the range. It is essentially a simpler version of the G30 model, with a fixed nozzle instead of an adjustable one. This makes it ideal for basic tasks like applying weed killer to driveways or patios where a single spray pattern is sufficient.
Owner reviews note that it is easy to use and clean, and the battery life is adequate for small jobs. The fixed nozzle is a limitation if you need to switch between mist and stream patterns. For the price, it is a solid entry-level sprayer, but the adjustable nozzle model offers better value for most users.
Greenworks 2-Gallon Handheld Sprayer (G40)
Best Value Large TankPros
- Large tank at a reasonable price
- Adjustable nozzle included
- Good battery life
Cons
- Heavier than 1-gallon models
- No backpack strap
The Greenworks 2-Gallon Handheld Sprayer offers a good balance between capacity and cost. It is essentially the same as the G40 model but without the backpack design, making it a handheld unit. This keeps the price lower while still providing the larger tank and adjustable nozzle.
Owner reviews appreciate the value for money, noting that it handles most yard tasks well. The lack of a backpack strap means you carry it by hand, which can be tiring with a full tank. For users who want the larger capacity without the backpack price, this is a solid middle-ground option.
Who should buy a Greenworks garden sprayer?
Greenworks garden sprayers are ideal for homeowners who want cordless convenience without the noise and fumes of gas-powered sprayers. They are best suited for applying liquid fertilizers, weed killers, and pest control products to lawns, flower beds, and gardens. The battery-powered design eliminates the need for manual pumping, providing consistent pressure at the push of a button.
If you have a small to medium-sized yard (up to half an acre), the 1-gallon models are sufficient. For larger properties, the 2-gallon or backpack models offer the capacity and runtime needed. Greenworks sprayers are also a good choice if you already own other Greenworks tools, as the batteries are interchangeable within the same voltage platform.
Performance and build quality
Greenworks sprayers use diaphragm pumps that deliver a steady flow of liquid. The pressure is consistent, which is important for even application of chemicals. The adjustable nozzles allow you to switch between a fine mist for delicate plants and a direct stream for targeted spraying. Owner reviews generally report good performance, with the sprayers handling common garden chemicals without issues.
Build quality is typical for the price point. The tanks are made from translucent plastic, allowing you to see the liquid level. The wands and nozzles are plastic, which keeps weight down but may not be as durable as metal alternatives. The batteries are sealed and protected, but users should avoid submerging the sprayer or leaving it in direct sunlight for extended periods.
What to check before buying a Greenworks sprayer
Consider the size of your garden and the types of liquids you will spray. Smaller tanks are easier to carry but require more refills. Larger tanks are heavier but cover more area per fill. Also, check the battery platform. Greenworks has two main systems: G30 (20V) for light-duty tools and G40 (40V) for high-power tools. Make sure the sprayer you choose matches your existing batteries, or factor in the cost of a new battery and charger.
Look at the nozzle options. Adjustable nozzles offer more versatility for different tasks. Fixed nozzles are simpler but less flexible. Finally, consider the warranty. Greenworks typically offers a 4-year warranty on tools and 2 years on batteries, but check the specific model for details.
Mistakes to avoid with garden sprayers
One common mistake is using the sprayer for chemicals that are not recommended. Always check the manufacturer's guidelines for compatible liquids. Another mistake is not cleaning the sprayer after use. Chemical residue can clog the nozzle and damage the pump over time. Rinse the tank and run clean water through the system after each use.
Do not overfill the tank. Leave some space for the pump to operate effectively. Also, avoid leaving the battery on the charger after it is fully charged, as this can reduce battery life. Store the sprayer in a cool, dry place away from direct sunlight to prevent plastic degradation.
Alternatives to Greenworks sprayers
If Greenworks sprayers do not meet your needs, consider other brands. Ryobi offers a similar range of cordless sprayers that use their 18V ONE+ battery system, which is widely compatible with other Ryobi tools. For heavier-duty use, Stihl and Karcher have gas-powered and electric options with higher pressure and larger tanks. Manual pump sprayers from brands like Chapin are also available for those who prefer a simpler, lower-cost solution.
