Important Considerations To Keep In Mind When Shopping For The Best Backpack Sprayer

If you want to see what is the best backpack sprayer, you’ll definitely find the following section useful. In fact, the criteria below guided us in establishing what makes the best backpack sprayer, and what differentiates a high-quality item from an average one.

Still, something you should carry in mind is that each user has different expectations and needs. That’s why we cannot say that a particular product is the best one for all people.

Type Of Sprayer

Backpack sprayers can be separated into two fundamental categories: manual and motorized sprayers. Manual sprayers tend to be more affordable than motorized units. However, some users might think of the manual operation as being a downside.

On the other side, motorized units are equipped with powerful batteries, and they make the job easier. So, if your priority is convenience, it makes sense to invest in a motorized product. The thing is that these devices might necessitate more maintenance on your behalf – so it’s worth considering this, as well.

Gas Powered Backpack Sprayer

At the same time, backpack sprayers may be categorized depending on the type of pump. That being said, you may choose from piston-powered backpack sprayers and diaphragm sprayers.

For one thing, piston-powered sprayers supply excellent pressure, of approximately 90 psi. Plus, while this type of unit is more affordable than its counterpart, it isn’t compatible with extremely harsh chemicals. That’s because the chemicals may damage the piston.

Meanwhile, diaphragm sprayers are significantly more resistant to chemicals, facilitating faster pressure – if needed. However, the downside is that they might necessitate more maintenance.

So, how do you decide between the two? If you don’t need extremely high psi, then a diaphragm unit will do wonders. Nevertheless, if you plan on doing overhead spraying, getting a piston pump makes more sense, providing you with high pressure for overhead application.

Design And Fit

As you’ve already seen in our backpack sprayer reviews, comfort is of utmost importance. And there are some critical elements that aim at diminishing the fatigue associated with using a backpack sprayer.

For instance, the best models are featured by adjustable, padded straps and tanks that are specifically designed to offer an excellent fit.

So, a sprayer with adjustable padded waist, shoulder and chest straps will make it comfortable for you to use the unit for numerous hours.

An excellent fit is significant for your comfort and safety. In other words, if you fail to fit the sprayer accordingly, certain incidents may occur. So, make sure you bear this in mind as you search for the best-rated backpack sprayer.

Capacity And Pressure

Depending on the size of your property and how you intend on using the backpack sprayer, you should check the unit’s capacity and pressure. Generally speaking, professional-grade sprayers generate high pressure, up to 150 psi, whereas most sprayers might supply up to 95 psi.

Using Manual Backpack Sprayer

However, this depends on the product. We recommend you to take this into consideration, to ensure that both the capacity and pressure of the device meet your specifications.

Nozzle Types – How To Replace Them?

There are three main types of nozzles, as following: flat fan, cone sprays, and streaming nozzles. Obviously, carefully selecting the right nozzle for your needs is critical to get the best performance from the chemical you apply.

When it comes to replacing the nozzles, you should always read the manufacturer’s instructions, so that you adjust the spray pattern accordingly.

Weight And Durability

As a rule of thumb, high-quality spray backpacks are equipped with durable tanks, which are made of high-density polyethylene. Concurrently, these units feature UV protection, for a boost of durability and safety.

That being said, we advise you to check the materials that the manufacturer used for engineering the unit.

As you might expect, depending on the materials used, the backpack sprayer might be either heavyweight or lightweight. It’s up to you to establish which element matters most to you – comfort or durability?

Evidently, the frequency of use is the main element that should be taken into the equation.

Maintenance Requirements

We all agree that a backpack sprayer is a long-term investment. Therefore, if you want to get plenty of use out of the unit, it makes sense to maintain it accordingly. While the manufacturer’s instructions might vary by the product, there are some critical guidelines that apply to all scenarios.

Backpack Sprayer Maintenance

For instance, you should always clean the sprayer after each use. Otherwise, you’ll imminently reduce the lifespan of the unit. You can use clean water or a commercial cleaner.

Secondly, during the cold season, you should use anti-freeze when storing the unit. And thirdly, you should lubricate the seals and O-rings at least once a year. If you use the unit frequently, you might make that twice a year.


If you’re searching for the best backpack sprayer, we advise you to take into consideration our recommendations. After conducting various tests, we can assure you that each product mentioned in this guide is worth considering.

However, before making your choice, analyze your needs, so that the product you pick will actually ease your work, not make it more tedious.

Although getting a reliable backpack sprayer might seem overwhelming, the information in our guide will hopefully make the shopping process easier.
