1. Field King Max 190348 – Our Top Overall Product

Field King Max 190348 Review

The Field King Max 190348 is our top pick for a large number of different reasons. Beyond just being easy to use, designed for comfort and a certain amount of durability, this is still a budget-friendly choice. A good investment without totally breaking the garden-allotted fund.

The Field King Max 190348 is built with quality in mind. One well-liked feature is the no leak pump design on the interior of the sprayer. This makes it much safer to use since you shouldn’t ever be feeling that hard-core chemical dripping down your back as you go on your way.

Another positive design feature is the 21-inch stainless steel wand with Viton seals to protect against corrosive chemicals. Being made from stainless steel is the real plus here as many times, on poorer quality models, the wand will be constructed from some wort of plastic without well-made seals. This lends towards the longevity of the product as well as its variability.

This product also includes such features as a lockable shut off valve partially made from brass, along with an in-line filter. The pump is easy to access and, perhaps most importantly for some people with various needs regarding usage, it comes with four different nozzles. These include an adjustable brass nozzle, two flat fans and a foaming nozzle.


  • No-leak interior pump
  • Easy to assemble
  • Parts are easily accessed and replaced
  • Top pressure of 150 PSI
  • Comes with four extra nozzles


  • Not the highest level of comfort
  • No pressure gauge
  • Difficult to know liquid levels

2. Chapin International 63985 Black & Decker Backpack Sprayer – Top Premium Product

Chapin International 63985 Black & Decker Backpack Sprayer Review

One of our two battery powered options, this option is incredible for those long jobs. The battery is a Black & Decker 20-volt lithium ion battery that means there is a lot of time for some continuous spraying.

Another huge plus for this option is that the top is constructed to be quite a wide mouth. This makes refilling it easier but is most important when considering times that you will need to clean the product out.

Unlike the option featured above, this model is made for a bit more comfort for the user, especially since it is intended for uses of multiple hours.  The shut-off valve has a cushion grip and the straps are made with more padding for prolonged use.

This option also comes with a variety of nozzles, three different ones including a poly cone nozzle and a fan nozzle.


  • Lightweight build
  • Comfort is a key player in design
  • Wide mouth funnel
  • Interior filter to stop debris clogging the nozzles
  • Quiet operation


  • Some say the battery could last longer
  • Some users would like a longer spray wand

3. Chapin 61900 4-gallon – Top Budget Friendly Product

Chapin 61900 4-gallon Review

Another four-gallon option with a translucent tank, this model is great for those that are looking for something that it still high quality and comfortable but easier on the budget. Many options from Chapin are going to be great investments for any gardener or homeowner.

Just like the previous Chapin model, this is also made with a bit of a wider mouth to make cleaning and refilling much more convenient than in many models. The filtration system on the interior is 3-stage and has a removable and cleanable filter.

Many users rave about the comfortability of the padded shoulder straps and the easy grip pump. There is an apparent pressure gauge that includes a shut-off valve. The wand is made with stainless steel and is 20 inches long.


  • Easy clean and refill with a wide mouth opening
  • Easily reaches high and difficult to reach areas
  • Has a three step filtration process


  • Does not have adjustable pressure
  • Requires frequent pumping

4. My 4 Sons Backpack Sprayer

My 4 Sons Backpack Sprayer Review

This option may be more expensive than some of the other options on our list, but part of this price is due to the extremely long-lasting and high value battery. Able to last for 6-8 hours on a single charge, this sprayer requires almost no pumping action whatsoever. Unlike the last option, this backpack sprayer does have options to change the pressure from 20-60 psi.

This is another sprayer with a stainless steel wand that allows for a longer lasting model, ready to go for years. The plastic squeeze handle does have a locking mechanism and the mouth is wide enough to enable easy cleaning and refilling. The design is made with a durable filtration system to keep debris from blocking the wand.

This sprayer comes with its own battery as well as the charger. Also included is a number of optional nozzles, such as a cone nozzle, fog, fan tip and is variable with brass and plastic options. Comfort was of high importance when designing this backpack. The shoulder pads are extremely thick to accompany the ability of the sprayer to have long-lasting spraying action.


  • Super long-lasting battery
  • Very comfortable
  • Extra-long wand


  • Is heavier than many other options
  • Some users complain about the size of the opening

5. Field King Professional 190328

Field King Professional 190328 Review

Another great option from Field King. This is also designed with an interior no leak pump design to make it another option when considering safety first with chemicals. The wand is an average 21 inches and the pump comes with four different options for nozzles. This option include a brass adjustable, two flat fans as well as a foaming nozzle. Many of the models produced by Field King are also compatible with Tee Jet nozzles.

This pump is also made to make it very easy to use for any experience level. the valves and other tricky parts are easily accessed to make them easily adjusted and replaced, if need be. There is an in-line filter to stop debris from clogging the sprayer. This also includes a lockable shut off valve.

Not as much of a focus has been placed on the comfortability of this model and the straps are not as padded as many other sprayers currently on the market. However, if very long-term jobs are not on your docket, then the easy usability of this model is a real pro for those new to the backpack sprayer scene.


  • No-leak interior pump
  • Easily repaired and replaced
  • Metal nozzles add to durability


  • Smaller tank opening
  • Not very comfortable
  • No pressure gauge

6. Roundup 190314 Backpack Sprayer

This sprayer from Roundup has one of the greatest variability in uses in comparison to any of the other options on our list. With the ability to be great for any job that involves spraying for weeds, controlling pests, growing produce or flowers and even cleaning off outdoor areas.

It is made for durability with a heavy-duty poly wind that features a comfort grip, a lock that enables continuous spraying and a filter that blocks debris from blocking the flow. The valves are made to be resistant to corrosive chemical exposure. The product also comes with three different types of nozzles, including poly adjustable, and high volume and low volume fans.

The product is also made with comfort in mind. The straps are padded as well as being adjustable with built in lumbar support to help facilitate comfortable spraying for long amounts of time.


  • Made for chemical resistance and longevity
  • Quite comfortable for long use
  • Three additional nozzles


  • Assembly can be difficult

7. Solo 425 4-Gallon Professional Piston Backpack Sprayer

Solo 425 4-Gallon Professional Piston Backpack Sprayer Review

This backpack sprayer is capable of functioning well with most chemicals that you could want to use in it. This includes liquid disinfectants, fertilizers, herbicides and pesticides. The wand is longer than an average sprayer is, this one coming in at 28-inches long. It also comes with assurances that it is unbreakable, a guarantee sought after by many gardeners investing in a sprayer.

The pump handle is said to be interchangeable for either left-handed or right-handed users and also comes with a shut-off valve that is able to lock in either the on or off position to minimize fatigue on long jobs. Viton seals are used to make the more fragile areas less prone to breaking and requiring repair. Solo made the top wide enough to make cleaning and refilling convenient.

This sprayer comes with multiple different nozzle options. These include plastic adjustable, fan spray, hollow cone, jet stream nozzle and it is also compatible with TeeJet nozzles.


  • Convenient use for both left and right dominant
  • Durable quality against corrosive chemicals


  • The shoulder straps do not adjust well
  • A bit expensive for some in comparison to the quality

8. Tomahawk Power Backpack Sprayer

Tomahawk Power Backpack Sprayer Review

For big time jobs, there is always our last option, the Tomahawk Power Backpack Sprayer. This option comes with a hard-core engine fueled by gas to help get your job done. At a super speedy pace, a gardener can spray an entire acre in 15 minutes. It is said to be about seven times as fast as normal pump sprayers.

This sprayer is adaptable to a very wide range of attachments and is able to reach up to 30 feet of spraying power. It is unique on this list as the only gas-powered sprayer. They are not widely used by small gardeners but are still quite useful for many different types of uses. It is going to be a little heavier than many since you are carrying an engine with you.

It has a practical design that makes it easy to use, comfortable to wear even with the heavier weight, and durable construction.


  • Multifunctional
  • Easily and quickly covers large areas
  • Durable and practical design


  • Some say the instructions are difficult to follow
  • It is heavier than many other kinds of sprayers

How to Choose a Backpack Sprayer

How to Choose Best Backpack Sprayers

1. Power

Depending on the type of jobs that you are wanting to use it for, the type of power (pump, battery, gas) will change the length of time a job takes as well as how much of your energy.

2. Pressure and Capacity

The pressure is an obvious one, affecting how much, how fast and the distance that the chemical will spray. The capacity will change the weight of the sprayer as well as the frequency of refilling.

3. Fit

The way that the backpack fits is going to entirely change the comfort level of the wearer and how long they are willing to work with the pack on.

4. Nozzle Types

Almost all sprayers will, or should, come with different types of attachable sprayers. This will help with certain types of jobs and the coverage and distance you are hoping to achieve.


1. Do I need to use different sprayers for Roundup and other chemicals?

Answer: Most chemicals can be used in the same sprayer; it should just be cleaned out before switching to a different chemical. However, for Roundup and other non-selective herbicides, a different sprayer should always be used.

2. With a 4-gallon backpack sprayer, how many square feet can I cover?

Answer: This really depends on the pressure the sprayer is calibrated to. Different amounts of the chemical will be spraying out at different pressures. Calibrations are figured out to deliver the volume of the liquid in terms of gallons per 1,000 square feet.

3. How should I clean my backpack sprayer?

Answer: The first step is to remove as much of the product from the sprayer as possible. After this, use plenty of hot water and dish detergent and be sure to run all of this through the nozzle itself to get rid of all residual chemical.


Now that you are armed and ready to tackle any chemical job with the help of your new chemical sprayer, you should be set for a whole new gardening experience! Be ready to protect your garden from harmful pests and diseases and get rid of those pesky invasive weeds. From gas powered “super sprayers” to lightweight applicators for a quick, thorough jobs, this article will hopefully have answered all of your backpack sprayer questions.
