The Best Backpack Sprayer Buyer’s Guide

Although you’ve now seen the top 10 best backpack sprayers on the market, you might still have a few questions. After all, you still have to pick only one from the list. You might need to know if you’ll be working at home or on a job site, what size yard you’re dealing with, and what kind of power you need. In any sense, this guide and FAQ section breaks down all the questions you have and the answers you need. Pretty soon you’ll be ready to strap on your new backpack sprayer and take on any jobs that lie ahead.

What materials should be used on a backpack sprayer?

Various parts of every backpack sprayer include different materials to adjust for durability, chemicals being used, and weight. For example, every tank is generally made out of chemical-resistant plastic compounds due to the obvious contents that you’ll be towing around. You wouldn’t use metal or untreated materials since they’d leach and leak right through the surface.

On the other hand, the nozzle of a backpack sprayer could be made out of a few different materials. The most sought-after option for a nozzle is brass. This is because brass doesn’t corrode easily, it doesn’t rust too much, and it can take bumps and drops without showing signs of damage. Brass nozzles are also easy to replace and reseal at your local hardware store, whereas plastic nozzles generally require specific designs to fit each model.

Another area to consider different materials is the wand. The wand of a backpack sprayer is the area that connects the nozzle to the trigger. Since it carries chemicals, you need to have something that can deal with constant exposure throughout the day. Some of the most common materials for sprayer wands include fiberglass, treated plastic, and treated stainless steel. Stainless steel is usually the most popular choice since it’s durable. However, it’s prone to rusting if you don’t wash off the exterior and dry it regularly.

Finally, the last material that affects the performance of your backpack sprayer is the backpack itself. Some of them come with padding, while others do not. Jump to the next question if you’re ready to see what you should look for in order to get optimal comfort.

What kind of back support do backpack sprayers provide?

For many years, backpack sprayers were pretty uncomfortable. The hard plastic pressing up against your back all day is never something that anyone looks forward to. However, in recent years, companies have been adding all kinds of support to make them much more comfortable for people who have to use them for extended periods of time.

Lower back straps, extra cushions, and plenty of other additions make these backpacks well worth the investment. The only two downsides to buying one with more comfortable features are 1) they usually cost more since they’re using more convenience features, and 2) they tend to keep you warm during sunny days. If you can look past those two issues, then anyone in the industry would tell you that they’re definitely something that you should look into.

Don’t worry if the sprayer you choose doesn’t come with enough back support. There are plenty of extra backpacks designed to make your experience much more relaxing. If you settle on a brand that doesn’t have enough comfort, then you’re more than welcome to buy the padding to create your own combination. Staying comfortable is key to success when you’re working hard outdoors!

Manual or battery powered

Electric backpack sprayers vs manual backpack sprayers

Another huge debate that people have before buying a backpack sprayer is whether or not it should be electric. There are plenty of benefits to owning an electric backpack sprayer, but they can also have a few downsides that steer people away from them. If you’re considering getting one, this section will help you clear things up before going through with your final decision.

The pros of owning an electric backpack include the massive convenience of never having to pump it to give it power. Being able to click start and begin spraying with the trigger immediately feels like a weight lifted off of your shoulders. It’s also convenient because you can usually charge them up overnight for several hours of continuous operation. However, the fact that there’s a limit at all tends to make some people wary of buying one.

The cons of owning an electric backpack sprayer include the fact that they weigh significantly more than pump-operated backpack sprayers. Since the batteries range from 18v to 24v, they can also take up a large portion of space. Needing to charge up a battery to use the sprayer is probably the biggest downside to most people. Although they charge in a few hours, they also only last for a few hours. This is perfectly fine for people working around their yard at home, but not so much for workers who need something that lasts for 8 or more hours a day.

Manual backpacks are nice because you never have to charge them. However, the need to pump them up for steady usage can wear people down. It’s also much harder to use if you have joint problems in your shoulders, elbows, or wrists. If you’re someone who doesn’t like to be tethered to a battery and you don’t mind pumping it up manually to build up the pressure, then manual backpack sprayers are almost always a good idea. You never have to worry about charging it up or replacing the battery if it dies off eventually.

What can backpack sprayers hold?

Backpack sprayers are designed for all sorts of outdoor applications. Although many people generally associate them with weed killers, these backpacks are also used to add insecticides to plants to prevent bugs from infesting them. They’re even used for powdered fertilizers to help grow plants. If you intend on having a garden, several trees, or crops, owning a backpack sprayer is an absolute essential to your shed.

Although they’re mostly used for yardwork, backpack sprayers are occasionally used for other applications, such as water spraying to pressure wash surfaces, painting designs, and even camping showers. The seemingly limitless amount of uses from these convenient sprayers makes them a great addition to anyone’s life.

Spraying weed

How do you store a backpack sprayer?

Since backpack sprayers almost always deal with chemicals, you shouldn’t store them anywhere where kids or unsuspecting guests have accidental access to them. They should be placed in a storage shed or an off-limits area of the garage. Much like most other gardening supplies, leaving them to be hit by weather elements is a surefire way to make them corrode and break down over time. You might even want to consider putting an old towel or sheet over it for improved longevity.

Something else you might want to consider is cleaning it after each use. While it might seem excessive, everything lasts longer when it’s properly taken care of. You could even clean it once a month to make sure that nothing pools up inside of it. This could lead to unwanted spills, chemical leaks, rust, bacterial growth, and all sorts of other unwanted side effects. If you want to know how to clean off your backpack sprayer, proceed to the next section.

On a side note, you could always get a stand for your backpack sprayer. While some of the options on this list come with their own storage carts, most of them require you to buy your own. They’re not too expensive and they’re definitely worth checking out. If you have children or pets, getting a cart to store your backpack sprayer is a huge necessity. They’re also very convenient since most of them come with wheels to let you move the sprayer around without having to carry it the whole time.

How do you clean a backpack sprayer?

Cleaning a backpack sprayer is much easier than you might think. With leading industries and companies recommending a clean after each and every use, it’s something you might want to get used to.

Start off by emptying any formula or extra liquid inside the tank. Make sure you follow the disposal instructions on the bottle or box that it came in. You should also make sure that it stays out of sight and reach of children and pets.

Next, fill the tank with hot water and a cleaning solution. This usually is done by using an ammonia compound, but you should make sure that it mixes with any possible leftovers from the previous chemical you were using. While it’s mixing in with the water, scrub down the nozzle, hose, and every other part of the backpack with a sponge, soap, and hot water. You can then proceed to seal with back up and leave it to sit overnight.

The next morning, all you have to do is spray the rest of the mixed cleaning solution out of the nozzle to clean out the inside of the tank and the hose. Refill the tank with hot water, flush it one more time through the nozzle, and you’re all good to go!
