Last Updated on January, 18th 2021


Plants aren’t immune from weeds, pests, and other damaging forces; even natural things can be bad for your garden. So, when it’s time to take charge of your situation, look into a backpack sprayer to make it easier for you to treat your plants quickly.

The question is, which one do you get? There are a lot of them available, so let’s weed through this (see what I did there?) together and figure out which one is best for you.

5 Best Backpack Sprayer Reviews

Backpack sprayers substantially range in features and price. There are plenty of options: manual or battery powered, plastic or brass handles, nozzle types, durability, and comfort. Here are some of the top options when looking for the right type of sprayer for you.

#1. Field King Professional 190328

Field King Professional 190328 No Leak Pump Backpack Sprayer for Killing Weeds in Lawns and Gardens

This no-leak design means you don’t have to worry about toxic products coming into contact with your skin. It comes with an internal agitator that helps mix the solution in the tank so that you’ll get an even amount of product over your entire application area.

The Field King Professional model comes with four nozzles, so you can vary the spray as you need it. And as if that wasn’t enough, its TeeJet compatibility expands the functionality of the machine.

The 150 PSI is plenty for any residential use and gives you control and flexibility over your droplet size and spray pattern. This machine is ideal for a large volume of work and is frequently used by professionals. By locking the sprayer mechanism into place, you can rest your hand while enjoying the same productivity.

With fewer parts to the model overall, this unit is less prone to wear and tear. It’s built to last, and even if it does break, the parts are easy to find and replace. The only things that seem to be lacking here are comfortable straps and lumbar support.


  • Affordable
  • No-leak design
  • Internal agitator
  • Ambidextrous pump handle
  • 150 PSI
  • TeeJet nozzle compatibility
  • Durable
  • Easy to repair
  • No lumbar support
  • No pressure gauge

#2. Solo 425 4-Gallon Professional Piston Backpack Sprayer

Solo 425 4-Gallon Professional Piston Backpack Sprayer, Wide Pressure Range up to 90 psi

This is one of the most popular backpack sprayers available. It offers a great balance of utility and economy; the design is simple but ingenious, and the sprayer provides great performance.

It offers a 90 PSI rating, which is still plenty of pressure for residential purposes, and is compatible with TeeJet nozzles, just like the Field King Professional, expanding its usability. You can change the spray pattern to fit your needs, and the Solo 425 is easily calibrated for different uses, which gives you plenty of versatility. Professionals will find this aspect especially useful.

You can change the pump lever for right- or left-handed use, increasing comfort. The 48-inch spray hose allows you to treat hard-to-reach areas, and the four nozzle options give you extra customization. The locking feature on the shutoff valve allows you to lock the sprayer in the “on” position, allowing you to rest your hand while still getting the work done.

Once again, the back strap isn’t the most comfortable, but there’s an optional harness available that makes it a bit more comfortable if you find that you need it. And trust us—if you have a large yard, you may need it. Otherwise, the straps it comes with are just fine.


  • Compatible with TeeJet nozzles
  • Locking feature
  • Economical
  • 90 PSI
  • No pressure gauge
  • No lumbar support

#3. Chapin International 63985 Black & Decker Backpack Sprayer

Chapin International 63985 Black & Decker Backpack Sprayer, 4 gal, Translucent White

This is one of the best backpack sprayers you can buy. It’s simple to use, comfortable to carry, and easy to maintain. It’s battery operated, giving you steady pressure with a uniform spray pattern, fixed droplet size, and constant flow rate. This effortless operation is super convenient, but it will cost you a little bit more up front.

This sprayer was designed with prolonged use in mind, so if you have a large garden, it’s the ideal solution, but it’s also great for anyone who wants something extremely simple to use. The adjustable back straps are padded, with lumbar support and chest support. We found this model to be one of the most comfortable backpack sprayers available.

The handle has a padded grip and comes equipped with a lock so you can relieve your hand while spraying. The extra-wide, 6”-diameter opening on the tank makes it easy to pour your liquids in without spilling them. It also allows you to clean the tank, so it lasts longer and doesn’t experience as much wear and tear.

The downside here is cost. An electric sprayer costs more than a manual sprayer, and this one is twice the price. The motor adds weight, but that’s where the padded straps come in. It’s a fantastic backpack sprayer that provides just the right mix of utility, comfort, and durability.


  • Durable
  • Easy to use
  • Triple filtration system
  • Padded straps with lumbar support
  • Wide tank opening
  • Expensive

#4. HD Hudson 97157 SP2 Piston Pump Bak-Pak Sprayer

HD Hudson 97157 SP2 Piston Pump Bak-Pak Sprayer, 47'

This 4-gallon sprayer has a solid steel pump handle and twenty-inch brass wand for extra durability. It also has a brass cone pattern nozzle with three extra nozzle attachments. The locking feature allows you to rest your hand while you spray, and the clear tank makes it easy to see your liquid level. It also comes with a plastic sprayer that works best with harsh chemicals, so you can choose which sprayer is appropriate for your application.

With 180 PSI, it offers some of the best pressure of any sprayer on our list, giving you more control over your spray pattern. The 47-inch industrial spray hose makes it easy to get to hard-to-reach places, making this a great solution for large gardens.

Working the piston manually with one hand while spraying with the other keeps the solution properly mixed and at the right pressure; tightening the seals will ensure you preserve the hoses, so they don’t leak. This is also a great solution for crawling around attics or other tight spaces.

This durable sprayer is highly versatile, and some users found that it works for more than just pests in their garden. They used it for paint and deck stain, making it well worth the cost. The only downside here is the lack of lines on the tank telling you how much product is left, but you can easily see through it to get an idea.


  • Versatile
  • Durable
  • Manual piston
  • Expensive

#5. My 4 Sons 4-Gallon Battery Powered Backpack Sprayer

M4 MY4SONS 4-Gallon Battery Powered Backpack Sprayer Wide Mouth with Steel Wand and Brass Nozzle, Battery Included New extra comfort heavy duty straps

The steel wand and brass nozzle make this battery-powered unit highly durable. You can extend the wand to forty inches for hard-to-reach places, and it includes a plastic wand for light use. With adjustable pressure up to 60 PSI and variable nozzle output, you get the control you need when you need it. This type of pressure is ideal for residential use, but it may not be enough for spraying more than your yard.

This machine features a long-lasting, easy-to-access lithium-ion battery. Nozzle attachments are easy to switch out, and the large tank opening makes it easy to fill and clean. A screen filter keeps large debris out of the tank to prevent clogging, a feature not found on all backpack sprayers. This sprayer also boasts a battery indicator light and voltage meter.

The trigger locks in place to rest your hand while spraying, and the shoulder straps are padded. Notable is the fact that a cell phone number and email address are printed directly on the label for any questions or concerns—that’s how confident this brand is that you’ll love their product.


  • Durable
  • Battery operated
  • Comfortable
  • Pricey
  • Not as versatile as other sprayers

Which Backpack Sprayer is the Best?

We’ve provided you with five excellent options because choosing the right sprayer is not a one-size-fits-all situation. Your garden size, budget, and intended use will help you decide.

For instance, not everyone needs a motorized pump; they add cost and weight, which wouldn’t appeal to folks who only need a light-use product. If you’re going to be using it often, then yes, a motorized pump, padded back straps, and extra PSI are surely a plus. For light use in a small garden, though, you can probably opt for a manual unit.

Spray pattern is another important consideration. Nozzles determine the spray pattern, and most users prefer a flat fan spray pattern, but there are many others.

Choosing a versatile backpack sprayer will allow you to figure out what works best for you, and a sprayer that’s compatible with aftermarket nozzles will allow even more customization, should you find that you need it.

It helps to get a backpack sprayer that will allow you to adjust the PSI and calibrate the unit as needed, so you can increase or decrease droplet size based on your individual needs.

Where to Buy a Backpack Sprayer

Backpack sprayers are available from local hardware and home improvement shops as well as online. If you’re looking into backpack sprayers, check out all of your options before making a final decision. Read some online reviews, and go to the store and talk to some people who know more about them. This will help you get a better idea of which unit might work best for you.

Some manufacturers offer warranties for their products, and retailers may have extended warranties or special return policies that may make you feel more comfortable purchasing from them. You can also shop around for the right price or ask if the store will price match what you found elsewhere.

Keep in mind that there are more manufacturers than what we reviewed here. Look into options from Jacto, D.B. Smith, Stihl, and SPS to make sure you’re getting the right combination of features and price.

Benefits of Backpack Sprayer

A backpack sprayer makes life so much easier when you need to treat your yard for weeds and other pests. Some are versatile enough to use to paint a fence or stain a deck.

Most backpack sprayers have locking triggers that allow you to set the sprayer nozzle and leave it. This is especially useful if you have a large garden or are using it in a professional capacity. This feature means your hand won’t be wavering because it’s tired, ensuring you get consistent coverage.

Sprayers with internal agitators allow you to get the consistent mixture you need without having to pump it yourself; as you spray, these agitators constantly mix the solution for you, so you get even application across your entire yard. Motorized pumps or battery-operated units can also provide efficient solutions for you rather than you having to pump a manual piston.

Most backpack sprayers come with a variety of nozzles, so chances are you’ll find the spray pattern you need without having to buy extras. However, getting a backpack sprayer that’s compatible with other nozzles increases its versatility and ease of use, which comes in handy for different applications, like paint or stain, in addition to weed and pest control.

Backpack sprayers allow you to choose what’s best for you in many different scenarios, so the benefits you may find in your chosen backpack sprayer will be completely different from your neighbor’s.


Believe us when we say that the best backpack sprayer for you is out there somewhere. You just have to decide what’s most important to you, and keep in mind that you may have to make some concessions. If you want the best on the market with the most features, you will inevitably pay a little bit more for it. But it will make your applications speedier, and it will be a much more comfortable and easier task.

If price is what’s important, you may sacrifice some conveniences, like padded back straps or a sizeable tank. However, you’ll get the durability you need at a price you can afford. Plus, if the unit comes with an extended warranty, you’ll get the peace of mind you need without stretching your budget. The backpack sprayer market continues to grow, so happy gardening!
