Greenworks 40V vs 24V Backpack Sprayer: Tested Review

 

If you’re torn between the Greenworks 40V vs 24V Cordless Backpack Sprayer, the main difference comes down to power and runtime. The 40V gives stronger spray and longer use, while the 24V feels lighter and easier for small yards. 

I’ve tested both in my own lawn work here in the U.S., and each one shines in different ways depending on the job. Stick with me, and I’ll break down the pros and cons so you can see which sprayer is the better fit for your needs.

Greenworks 40V Cordless Backpack Sprayer

I’ve been using the Greenworks 40V Cordless Backpack Sprayer for some time now, and it has changed the way I handle my lawn and garden. The simple design, steady spray, and battery power make it a tool I reach for often. 

It takes away the hassle of pumping and lets me focus on the job. For me, it feels like a mix of comfort, speed, and real results all in one.

What I Like

I’ve been using this backpack sprayer for a while now, and there are a few things that really stand out. These are the features that made my lawn care routine so much easier.

• No pumping needed – The battery does all the work, which saves energy and keeps the spray steady. I can walk around my yard without feeling like I’m in a workout.
• Comfortable straps – The padded straps and waist buckle feel like a hiking pack. They spread the weight evenly, so I can spray for longer without sore shoulders.
• Consistent spray pattern – Unlike manual sprayers, the pressure stays even. That means my lawn gets treated evenly, and I don’t waste product.
• Multiple nozzles – The included tips make it easy to switch from a wide fan spray to a focused stream. I use different ones for fertilizer, weed control, and pest spray.
• Great battery system – Since it uses the Greenworks 40V platform, I can swap batteries with my other tools. That keeps downtime to almost zero.

What Could Be Better

Every product has room for improvement, and this sprayer is no exception. That said, none of these are deal breakers.

• A little heavy when full – Four gallons of liquid on your back is no joke. The straps help, but if you’re small-framed, it takes some getting used to.
• Plastic build – The tank is durable enough, but I’m careful not to drop it on hard ground. A thicker shell would give me even more confidence.
• Battery life depends on use – For small yards, one battery is more than enough. But for large properties, having a second battery on hand makes the job smoother.

My Personal Experience

I’ve been using Greenworks tools for over two years, and this sprayer is one of the best investments I’ve made. It saves time, reduces effort, and makes lawn care feel less like a chore and more like a routine I actually enjoy.

Compact

I was surprised at how slim the design is for a 4-gallon sprayer. It doesn’t stick out awkwardly, and I can store it in a corner of my shed without taking up much space.

Lightweight

Compared to older metal sprayers, this one feels easier on the body. Yes, it gets heavier when full, but the straps balance it well. I often forget I’m carrying that much liquid.

Good for Small Gardens

Even though it’s powerful, it’s not overkill for smaller lawns. I’ve used it in tight spaces and garden beds without worrying about overspray. The nozzle control makes it easy to fine-tune.

Capacity

Four gallons is the sweet spot. I can cover both my front and backyard in one fill. With my old sprayer, I had to refill halfway, which was frustrating.

Runtime

On a single charge, I can spray up to 100+ gallons depending on the setting. That means I don’t have to stop mid-job, which keeps me in a rhythm.

Battery

The fact that it shares the same 40V battery with my Greenworks mower and trimmer is a game-changer. I don’t need a separate charger or a bunch of different batteries cluttering my space.

Power

At 70 PSI, the spray is strong enough to reach far spots in my yard. I don’t have to walk into every corner—it throws a consistent stream that saves me steps.

Best for Medium to Large Yards

This sprayer really shines if you have more than a tiny patch of grass. For medium or larger yards, the time and energy saved are huge. It turns what used to be a sweaty afternoon into a quick, manageable task.

Greenworks 24V Cordless Backpack Sprayer

I’ve been testing this sprayer for some time now, and it has made garden work much easier. It feels light on the back, yet it holds enough water to handle long tasks without stopping. 

The spray power is strong and steady, reaching far spots in my yard with ease. For weeds, cleaning, or simple watering, this tool has been a reliable helper.

What I Like

I’ve been using this sprayer for a while now, and a few things really stand out. Here’s what I enjoy most about it:

• Long spray distance – Reaching up to 25 feet makes it easy to cover larger spots without walking back and forth.
• Comfortable straps – The double-padded shoulder straps feel gentle on my back, even after hours of use.
• Nozzle options – The 5 different tips give me flexibility, whether I need a fine mist or a strong stream.
• Solid runtime – With the 24V battery, I can finish a good amount of work before thinking about recharging.
• Durable build – The plastic feels sturdy yet light enough for everyday garden use.

What Could Be Better

No product is perfect, and this one has a few areas where I think it could improve. Still, none of these are deal-breakers—they’re more like small tweaks.

• Weight when full – With 4 gallons of water, it can feel a bit heavy. A waist strap could make it even easier to carry.
• Battery not always included – Some buyers may get confused since the “tool-only” version doesn’t come with a battery.
• Refilling – The large tank is great, but it would be nice if the opening was slightly wider for quicker fills.

My Personal Experience

I’ve been using this sprayer for over 2 years, and it has been a reliable partner for everything from weed control to light cleaning. What I like most about Greenworks as a brand is how they make tools that are simple to use, battery-powered, and easy on the body.

Compact

One thing I’ve noticed is how compact it feels on my back. It doesn’t stick out too much, and it moves with me. This is great when I’m walking between narrow garden paths or working around flower beds.

Lightweight

Even with the tank, the sprayer feels lighter than many others I’ve tried. The design spreads the weight well, so I don’t get that “dragging down” feeling. It reminds me of carrying a school backpack instead of heavy gear.

Good for Small Gardens

In my small front garden, it feels like overkill at times, but in a good way. A quick walk with the fan nozzle, and I’m done in minutes. I used to use hand-pump sprayers, and the difference is night and day. No more sore wrists.

Capacity

The 4-gallon tank is generous. For small yards, it feels like I barely use half a tank. For bigger jobs, I can keep going without stopping to refill often. That extra capacity gives me peace of mind.

Runtime

Battery life has been solid. On a single charge, I can spray more than enough for my garden. It’s nice not having to stop mid-task to recharge. If I compare it to my old corded sprayer, this feels like pure freedom.

Battery

I’ve used Greenworks 24V batteries across different tools, and that’s what I really appreciate. The same battery works for my sprayer, hedge trimmer, and even my drill. It saves money and space because I don’t need multiple chargers lying around.

Power

At 70 PSI, it’s powerful without being too much. I’ve used it to reach weeds at the back of my yard where hoses won’t go. The pressure feels steady, so I don’t need to repeat the same spot twice.

Best for Medium to Large Yards

While it shines in small gardens, this sprayer is truly at its best in medium to large yards. Covering wide areas is faster, and the comfort straps keep me going without feeling worn out. For anyone tired of hand-pump sprayers, this is like upgrading from a bicycle to a motorbike.
