Testing Greenworks 80V vs 40V Backpack Sprayer in Action

 

When I first looked at the Greenworks 80V vs 40V Backpack Sprayer, I wanted a clear answer— which one truly fits different lawn sizes? The 80V gives more power and longer runtime, while the 40V feels lighter and easier for small jobs. 

From my own use, the 80V worked better on large U.S. yards, but the 40V was easier on my back for quick weekend spraying. Both have pros and cons, so let’s walk through the details and see which one makes more sense for your needs.

Greenworks 80V Backpack Sprayer

I’ve been using the Greenworks 80V Backpack Sprayer for my lawn and garden work for quite some time. It has made my spraying tasks faster, easier, and far less tiring. 

I like how it gives a steady spray, runs smoothly, and feels strong in the hands. I’ve used many sprayers before, but this one stands out because it mixes power with comfort in a simple design that works every day.

What I Like

Over the years, I’ve tested different backpack sprayers, and a few things about the Greenworks 80V model really stood out. Here’s what I appreciate the most:

• Powerful Pressure & Coverage – With up to 70 PSI, it sprays further than many others I’ve tried. This means I don’t have to walk back and forth too much, which saves time and energy.
• All-Day Battery Life – On a single charge, it covers an impressive amount of work. I’ve been able to finish full days of spraying without worrying about a dead battery.
• Comfortable Straps – The padded shoulder straps make a huge difference. Carrying a full 4-gallon tank can be heavy, but the straps spread the weight well.
• Multiple Nozzle Options – The different spray tips give me flexibility. I can switch between fertilizers, insecticides, and weed control without worrying about uneven coverage.
• Quiet & Eco-Friendly – Since it’s battery-powered, I don’t deal with the noise and fumes of gas sprayers. It feels cleaner, lighter, and easier to handle.

What Could Be Better

No product is perfect, and I like to be honest about small things that could improve. These aren’t deal-breakers, but worth mentioning:

• Battery Fit Could Be Smoother – Sometimes sliding the battery in or out takes an extra push. It still works fine once you get the hang of it, but a smoother design would make it even better.
• Tank Weight When Full – A full 4-gallon tank is heavy. While the straps help, beginners might feel the weight at first. I learned to pace myself, and it gets easier with use.
• Storage Space for Accessories – The nozzles and parts are great, but having a built-in holder or pouch would make them easier to carry around.

Even with these minor points, the benefits far outweigh the drawbacks. I see them as small improvements that could make an already excellent sprayer even more user-friendly.

My Personal Experience

I’ve been using the Greenworks 80V Backpack Sprayer for over two years, and it has become one of my most reliable tools in lawn care. From design to performance, it delivers consistently.

Design

One of the first things I noticed was how thoughtfully this sprayer is built. The tank is clear enough to monitor fluid levels, and the straps adjust easily to fit different body sizes. It feels like Greenworks designed it with comfort in mind. Compared to older sprayers I’ve used, this one feels modern and efficient. For me, the design takes away the usual “strain” of spraying and makes the task more manageable.

Performance

Performance is where this sprayer shines. The 80V battery powers a strong, steady stream without fading halfway through the job. I’ve used it for both large lawns and smaller garden beds, and it delivers consistent coverage. Switching nozzles lets me fine-tune the spray, whether I’m applying fertilizer, weed killer, or insect control. The best part? I can trust it to work every single time, which saves me the frustration I’ve had with cheaper models.

Build Quality

The overall build feels solid and dependable. The materials are sturdy, the hose doesn’t kink easily, and the wand has a nice weight to it. After months of regular use, I haven’t noticed leaks or cracks, which is something I dealt with in other sprayers. Greenworks seems to focus on long-term durability, and that’s what gives me confidence in the brand as a whole.

Greenworks 40V Cordless Backpack Sprayer

I’ve been testing the Greenworks 40V Cordless Backpack Sprayer for some time, and it has made my spraying jobs simple. The battery means I do not have to pump by hand, which saves me effort. The spray stays even, the straps sit well, and it works great for both small yards and big areas.

What I Like

I’ve used different sprayers before, but the Greenworks 40V Cordless Backpack Sprayer really stood out for me. Here’s why I like it:

• No pumping needed – I love that it’s battery-powered. I can just walk and spray without breaking rhythm. It saves my arms and lets me cover more ground with less effort.
• Consistent spray – Unlike manual sprayers, this gives me an even spray pattern every time. That’s important when I’m applying fertilizer or weed killer because I want full coverage.
• Comfortable to wear – The padded straps and waist buckle make it feel light even when full. I can wear it longer without back pain or shoulder fatigue.
• Versatile nozzles – The 5 spray tips are a game-changer. I can switch from a fine mist for watering to a strong stream for weed control in seconds.
• Great battery system – Since it runs on the Greenworks 40V platform, I can share batteries with my other tools. That makes the whole system more valuable.

What Could Be Better

Every tool has small things that can be improved, and this one is no different. Still, none of these are deal-breakers for me.

• A bit heavier when full – With 4 gallons of liquid, it can feel heavy at first. But the straps balance the weight well, so it’s manageable.
• Battery sold separately – The sprayer doesn’t always come with a battery. If you don’t already own Greenworks tools, you’ll need to buy one. But on the flip side, that also means you can use one battery across several tools.
• Minor nozzle tightening – I noticed a little dripping the first time because I didn’t tighten the nozzle enough. Once I adjusted it, the problem was gone.

My Personal Experience

I’ve been using Greenworks tools for a while, and this sprayer fits right into their lineup. It feels like the brand really understands what homeowners and lawn enthusiasts need—tools that save time, reduce hassle, and deliver consistent results.

Design

The design feels practical and well-thought-out. The tank holds 4 gallons, which is enough for me to spray both the front and backyard without refilling. The straps are double-padded and adjust easily, so it doesn’t dig into my shoulders. It honestly feels like wearing a good hiking backpack, but with the bonus of keeping my lawn in check.

Performance

Performance is where this sprayer shines. The 70 PSI pressure and 25-foot spray range make a huge difference compared to the pump sprayers I used before. I don’t lose pressure mid-job, which means my coverage is smooth and even. For me, it’s like trading a hand-pumped bicycle tire for an air compressor—just night and day.

Build Quality

The build quality impressed me. The plastic tank feels sturdy, not thin or flimsy like cheaper models. The wand, lock system, and straps all feel solid. After several uses, I haven’t had leaks or cracks, which tells me it’s built to last. Greenworks also backs it up with a warranty, which adds peace of mind. It’s the kind of gear you can rely on for both weekend projects and heavier seasonal spraying.
