For instance, you might want to decide whether you need a manual or a motorized sprayer. Regardless of the one you choose – you’ll also have to choose between a piston or diaphragm pump. Let’s see what to look for in the best backpack sprayer. But before we get into that, what are the advantages of a backpack sprayer? Check below!

Advantages of a Backpack Sprayer

7 Best Backpack Sprayers to Make Caring for Your Garden Easier

  • It’s cheap, portable and straightforward to use compared to other herbicide application equipment.
  • Backpack sprayer makes it possible to treat a selective (spot spraying) area or a newly established population. You can’t damage non-target vegetation.
  • Applications can be made in terrain and other areas that are hard to access. That adds to the convenience that comes along with a backpack sprayer.
  • They’re sturdy and time-saving tools. You can get your spray work done in no time because of the fine spray and coverage of these backpack sprayers.

Features to consider before you buy a backpack sprayer

It’s clear that for you to buy the right backpack sprayer, you should know the features you want in one. Highlights give you a clear picture of what a given sprayer can do and what to expect from them. We discuss six critical features that can make or break your spraying experience. They include the liquid capacity, backpack power, spray or flow rate, dimensions, weight, and construction material.

Liquid capacity

Whether you’re looking for the best backpack garden sprayer or just another backpack lawn site sprayer, the liquid capacity is a feature you can’t wish away. Different sprayers have different volume.

If you intend to spray large farms or lawn, then going for a sprayer with a large capacity will do fine – that’s a 4-gallon sprayer.
You can pick one from our seven recommendations above. Small liquid capacity is ideal for small applications. However, sprayers with low volumes might give you repetitive refilling work.

Powered by

There are two types of backpack sprayers available on the market today. That is, the manual and motorized/automated sprayers.

The manual pump requires you to pump while the battery-operated runs on battery.
For convenience and reliability, the automatic sprayer will give the best service. You might want to consider our pick – Petra Battery Powered Backpack Sprayer as the best battery powered backpack sprayer. If you’re on a fixed budget, it does not mean that manual sprayers are worthless. Our Roundup Backpack Sprayer is the best backpack pump sprayer with value for money. There is always something for everyone.

Spray/Flow rate

7 Best Backpack Sprayers to Make Caring for Your Garden Easier

When making your choice, keep a close eye on the flow rate. You want to buy a sprayer that will meet your needs 100%, and there’s no room to gamble. So, how is the flow rate significant? Pressure differs from one sprayer model to another. Some can only reach 15 psi while others build up to 150 psi. What you should understand is that pressure consistency in the tank is essential as you need to spray the liquid in a constant from the start to the end. Most of the sprayers’ pressure decrease as the contents of the tank decrease. Our Roundup Backpack Sprayer is an excellent example of a sprayer with high psi.


Knowing the right aspects of your ideal backpack sprayer is imperative.

If you go for a sprayer with wrong size, then you may experience difficulties when it comes to storage and even usage.
If your primary spraying area is confined – having a sprayer with some specific dimensions is not an option. An example could be in a greenhouse where you have some particular paths to follow. Also, the length of the spray wands and hose should be what you want. Nothing should stop you from reaching up high or down low as you wish. For a sprayer with smaller dimensions, you check the Chapin Commercial Backpack Sprayer, but if you’re interested in a larger one, then the Field King Professionals Backpack Sprayer or MY4SONS are ideal.


Weight is yet another critical feature to consider. You want to buy a sprayer that you’ll be comfortable carrying around. Ensure that you check the weight first and be satisfied with it before you buy. Another thing that goes hand in hand with weight is the shoulder strap. It’s almost useless to buy a sprayer that’s lightweight but with inferior straps. In our review, Petra Electric Fogger Atomizer Backpack Sprayer is the lightest while the Field King Professionals Backpack Sprayer is the heaviest. Choose wisely.


Finally, you must have durability in mind when you go shopping for a backpack sprayer. You probably want something that will serve you for as long as possible. That means you’ll have to consider a sprayer that is built with high-quality materials, one that does not leak and if possible, with added UV protection. All of our reviewed sprayers are made with sturdy material and therefore suitable for you. However, you might want to check the Roundup Backpack Sprayer, which is also the best value, or the Chapin International Backpack Sprayer – Editor’s Choice.


Yes. As you may already know, all backpack sprayers are not built the same. Each is constructed to serve a specific function. Some will weigh more than others. The weight of a backpack sprayer will depend on the material used in its construction and its dimensions. For a lightweight option, you might want to look for smaller backpack sprayers.

Small gardens do not require backpack sprayers with large capacity. There are specific garden sprayers that come in different varieties. However, for a backpack sprayer, an ideal one is the one that can meet your small garden needs as you see them. For instance, it should spray selective areas accurately without touching the unwanted spots. Most of the standard backpack sprayers are ideal for small gardens.

Not all backpack sprayers can be used to do everything. Every sprayer is designed to handle a specific individual task apart from the original work. For the best bleach backpack, you can check out the M4 Battery Powered Backpack Sprayer that is compatible with quite a wide range of other chemicals. But using highly concentrated bleach can be dangerous.

Our Verdict

The above seven products are the best backpack sprayers where reliability meets comfort. Every backpack has something to offer. We were keen on the material, capacity and power when picking the best sprayers. What impressed us about the above picks is that regardless of their working mechanism – either manual or motorized, they did not fail to perform as expected.
