Greenworks 40V 2-Gallon Backpack Sprayer
Best OverallPros
- Excellent runtime with 40V battery
- Comfortable backpack design
- High flow rate covers large areas fast
Cons
- Battery not included
- No wand storage on unit
This 40V backpack sprayer is the top choice for homeowners with large lawns or gardens. The 2-gallon tank holds enough solution for most residential tasks, and the 0.8 GPM flow rate means you can treat a 5,000 sq ft lawn in about 15 minutes. Owner reviews consistently praise the even spray pattern and the lack of hand-pumping fatigue.
The padded shoulder straps and back panel make it comfortable for extended use. It uses the same 40V battery as Greenworks lawn mowers and trimmers, so it fits easily into an existing ecosystem. The main drawback is that the battery and charger are sold separately, which adds to the upfront cost.
Greenworks 24V 1-Gallon Handheld Sprayer
Best BudgetPros
- Very affordable entry point
- Lightweight and easy to carry
- Works with 24V Greenworks tools
Cons
- Small tank needs frequent refills
- Lower flow rate for larger areas
If you have a small garden or just need to spot-treat weeds, this 24V handheld sprayer is a great value. The 1-gallon tank is perfect for patios, flower beds, or driveways. Owners like the simple trigger operation and the fact it uses the common 24V battery platform, which is often included with Greenworks starter kits.
The flow rate is modest at 0.4 GPM, so it is not ideal for large lawns, but it handles precise applications well. The wand is adjustable from a stream to a fan spray. Some users note the plastic tank can feel a bit thin, but it holds up fine for occasional use.
Greenworks 40V 1-Gallon Handheld Sprayer
Best for Medium YardsPros
- Higher flow rate than 24V model
- Comfortable grip and trigger
- Good for medium-sized lawns
Cons
- Battery not included
- Still a handheld, can get heavy
This 40V handheld sprayer offers a noticeable step up in power from the 24V version. The 0.6 GPM flow rate allows you to cover a 3,000 sq ft lawn without stopping to refill as often. Owners appreciate the variable trigger that gives good control over spray volume.
It is a good middle-ground option if you want the 40V battery compatibility but do not need a backpack. The tank is translucent, making it easy to see liquid levels. A few reviews mention the wand connection can leak if not tightened properly, but this is a minor issue.
Greenworks 24V 2-Gallon Backpack Sprayer
Best for ComfortPros
- Ergonomic backpack design
- Large 2-gallon capacity
- Lower price than 40V version
Cons
- Slower flow rate
- 24V battery may not last as long
For users who want a backpack sprayer but are on a tighter budget, this 24V model is a good option. It holds 2 gallons and the backpack straps are well-padded for comfort. Owners say it is much easier on the back than carrying a handheld unit for long periods.
The flow rate is 0.5 GPM, which is slower than the 40V backpack, so it takes a bit longer to cover the same area. It uses the 24V battery platform, which is less powerful but often cheaper. Some users wish the wand had a trigger lock, but the continuous spray mode works well.
Greenworks 40V 4-Gallon Backpack Sprayer
Best Heavy-DutyPros
- Massive 4-gallon tank
- Highest flow rate at 1.0 GPM
- Durable commercial-grade build
Cons
- Heavy when full
- Overkill for small yards
This is the most powerful Greenworks sprayer, designed for large properties or light commercial use. The 4-gallon tank and 1.0 GPM flow rate mean you can treat up to an acre without refilling. Owners who manage orchards or large vegetable gardens say it saves significant time.
The build quality is notably better than the smaller models, with a reinforced frame and a heavy-duty pump. It is heavy at 12.3 lbs empty, and over 45 lbs when full, so it is best for strong users. The 40V battery provides ample runtime, but you may want a second battery for all-day jobs.
What to check before buying a Greenworks garden sprayer
Battery platform is the first thing to consider. Greenworks uses both 24V and 40V systems. If you already own Greenworks tools, choose the sprayer that matches your existing batteries to save money. The 40V platform offers more power and longer runtime, while 24V is lighter and cheaper.
Tank size matters for how often you need to refill. A 1-gallon tank is fine for spot treatments and small gardens. A 2-gallon tank suits most medium to large lawns. The 4-gallon tank is for heavy-duty use but becomes very heavy when full. Flow rate (GPM) determines how fast you can cover an area. Higher GPM means faster work but uses more solution per minute.
Build quality varies across models. The backpack designs generally have better padding and straps than handheld units. Check the wand and hose connections, as some owners report leaks if fittings are not tight. Warranty is typically 4 years for Greenworks tools, which is standard for the brand.
Mistakes to avoid when choosing a sprayer
Buying the wrong battery platform is a common mistake. If you buy a 40V sprayer but only have 24V batteries, you will need to buy new batteries and a charger, increasing the total cost. Always check compatibility with your existing tools first.
Another mistake is underestimating the weight of a full tank. A 2-gallon backpack sprayer weighs about 25 lbs when full. A 4-gallon model can exceed 45 lbs. If you are not used to carrying that weight, a handheld or smaller backpack may be more practical. Also, do not assume a higher flow rate is always better. For precise spot spraying, a lower flow rate gives you more control.
Finally, do not forget to clean the sprayer after each use. Chemicals can clog the nozzle and damage the pump over time. Rinse the tank and run clean water through the system after every application to extend the life of the sprayer.
FAQs
Do Greenworks sprayers come with a battery and charger?
Most Greenworks sprayers are sold as tool-only, meaning the battery and charger are not included. You need to buy them separately or use existing Greenworks batteries.
Can I use any Greenworks battery in these sprayers?
You must use the correct voltage. 24V sprayers only work with 24V Greenworks batteries, and 40V sprayers only work with 40V batteries. They are not interchangeable.
How long does a battery last on a Greenworks sprayer?
Runtime depends on the battery capacity and flow rate. A 2.0Ah 40V battery typically lasts 20 to 30 minutes of continuous spraying. Larger 4.0Ah batteries can last 45 to 60 minutes.
Are Greenworks sprayers suitable for herbicides and pesticides?
Yes, they are designed for water-based chemicals like fertilisers, weed killers, and pesticides. Always rinse the tank thoroughly after each use to prevent corrosion.
What is the warranty on Greenworks sprayers?
Greenworks offers a 4-year limited warranty on most of its tools, including sprayers. This covers defects in materials and workmanship but does not cover normal wear or misuse.
Can I adjust the spray pattern on a Greenworks sprayer?
Yes, all models have an adjustable wand that lets you switch from a narrow stream to a wide fan spray. This gives you control over coverage and precision.
How do I clean a Greenworks sprayer after use?
Empty the tank, fill it with clean water, and run the sprayer for a few minutes. Then empty the water and let the tank dry with the cap off. This prevents clogs and pump damage.
Is the Greenworks 40V backpack sprayer comfortable for long use?
Yes, it has padded shoulder straps and a contoured back panel. Most owners find it comfortable for up to an hour of continuous use, though the 4-gallon model is heavier.
Can I use a Greenworks sprayer for cleaning tasks?
These sprayers are designed for garden chemicals, not high-pressure cleaning. They lack the PSI needed for washing cars or patios. For that, consider a Greenworks pressure washer.
Where can I buy replacement parts for Greenworks sprayers?
Replacement wands, nozzles, and seals are available on the Greenworks website and through major retailers like Amazon. Check the model number for compatibility.
