The Best Backpack Sprayers 2021: Our Choice

FlowZone Shower 4-Gallon Multi-Use Continuous-Pressure Backpack & Rolling Lithium-Ion Sprayer

Review:

This FlowZone backpack sprayer is an excellent solution for those who hate hand pumping. The device runs on a rechargeable battery and features a diaphragm-type inner pump. It provides a permanent pressure of 45 psi, which is ideal for fast and even chemical applications. Two nozzles available let you choose between the short-distance precise application and the long-distance mist spraying. FlowZone is compatible with various types of liquids – from water to toxic and aggressive chemicals.

What we think:

The sprayer is heavier and bigger than most backpack options but it features wheels for an easy transportation. Unfortunately, the wheels are not pneumatic and relatively small, so you can experience some difficulties with moving it across a non-even terrain. The overall performance is consistent; one battery lasts for about an hour. That said, there are complains about occasional leaks and drips.

PROS

  • no manual pumping;
  • consistent performance;
  • easy to clean and refill;
  • powerful batteries;
  • two adjustable nozzles included.

CONS

  • there are reports on occasional leaks;
  • the wheels could be more serious.

Solo 425 4-Gallon Professional Piston Backpack Sprayer

??? See Current Price

 ✅ Suitable For Short Persons As Well

The base is cleverly designed to keep it upright, even on uneven surfaces. Even as a short person, I can set it on a trash can, add chemicals and water, and just step into the straps and hoist it onto my shoulders, without stressing my back.

Review:

This Solo backpack sprayer is a classic example of a conventional manual sprayer with a piston pump. It boasts a wide pressure range and a capacious 4-gallon tank. Four various nozzles available allow to resolve a wide spectrum of tasks. The UV-resistant tank suits for working in all weather conditions. The sprayer is compatible with a broad range of chemicals, including pesticides, fertilizers, and herbicides. Strong polyester straps provide a hassle-free transportation of the unit.

What we think:

The sprayer does its work fine – the pump is easy to use, and the wand seems to be well-made. Four nozzles give a lot of versatility. The tank has clear readable gallon measurements. The only small complaint is about the straps: they are a sort of narrow, and when the reservoir is full, they cause a certain discomfort.

PROS

  • a wide pressure range;
  • easy to use and refill;
  • compatible with multiple chemicals;
  • a capacious UV-resistant tank;
  • four nozzles included.

CONS

  • the straps are narrower than expected.

Field King Professional 190328 No Leak Pump Backpack Sprayer

??? See Current Price

 ✅ Comfortable Straps for Convenient Spraying

The tank does hold 4 gallons and it does have a built in screen so debris and what not doesn’t get into the container, you can easily remove it though. I do also like the larger opening so you can fill it easily. The backpack portion of it has padded straps and a connecting two part quick connecting harness, so it does fit well and comfortable to the chest and back.

Review:

The strong point of this Field King backpack sprayer is its ability to handle chemicals in various aggregate states – liquid or powders. However, it is not for liquids with small solid or abrasive parts. It has an impressive pressure range – the maximum value is 150 psi, which allows reaching even remote places and making spraying even more precise. The four interchangeable nozzles add versatility, and high-quality fittings and shut-offs increase the unit’s durability.

What we think:

The sprayer works as advertised – it is fast and effective. During testing, we noticed no leaks – the wand is really well-made, and so are the fittings. The only thing that needs to be improved is a pump handle. It is not foldable, which creates certain inconveniences during the storage. You have to disassemble it every time before hanging the unit on the wall.

PROS

  • powerful and efficient;
  • a multi-purpose unit;
  • an impressive pressure range;
  • four nozzles cover all the gardener needs;
  • high-quality materials;
  • no leaks detected.

CONS

  • an inconvenient pump handle.

Chapin International 63985 Black & Decker Backpack Sprayer

Review:

Being one of the most recognizable brands around, the Chapin backpack sprayer has many advantages. It is reliable and long-lasting – you may work all day long with a single battery charge. It is convenient – a consistent permanent pressure is maintained without the need for manual pumping. Finally, it is relatively lightweight and features high-quality padded straps. This is a multi-purpose unit, and 3 nozzles included make it even more versatile.

What we think:

We love both the construction and the performance of the sprayer. It is easy to clean and refill while all the parts and components seem to be of high quality. The battery is powerful enough to work several hours in a row without recharging. That said, its hose is a bit shorter than desired, which can be a trouble sometimes.

PROS

  • reliable and durable;
  • a long-lasting battery;
  • soft padded straps;
  • three nozzles included;
  • easy to use and clean;
  • high-quality materials.

CONS

  • the hose could be some longer.

Tahoe Tool Company 50200202 Backpack Pump Sprayer

Review:

If you need a budget-friendly option, this 4-gallon backpack sprayer from Tahoe Tool is for you. It is one of the most affordable sprayers that comes with a variety of nozzles to cover all your needs. The unit features a semi-transparent 4-gallon reservoir and adjustable straps for the comfortable transportation.

What we think:

You won’t find premium materials or any unusual features in this sprayer. It is a simple and affordable manual pump, which does its job honestly. A variety of nozzles included is a nice addition.

PROS

  • affordable and easy to use;
  • various nozzles available;
  • lightweight;
  • a good capacity.

CONS

  • occasional leaks are recorded;
  • the straps are of average quality.

My 4 Sons 4-Gallon Battery Powered Backpack Sprayer

Review:

For those looking for a backpack power sprayer with an expanded range of features, this My 4 Sons unit is a primary option to consider. It comes with powerful lead-acid batteries, which are known for their expanded lifespan if compared to conventional Li-ion batteries. The unit provides a consistent pressure of up to 60 psi while most of its competitors offer no more than 40-45 psi. Apart from a plastic wand, there is a premium-quality steel wand that can resist most aggressive chemicals. Finally, the sprayer comes with eight various nozzles, which means it will cover the vast majority of the gardener needs.

What we think:

A lead-acid battery is a controversial solution. It takes longer to fully charge it while its lifetime is also longer. In general, we have no complaints about the sprayer’s quality and performance. That said, the sprayer is more expensive than most similar options. It comes with a cart, which, frankly speaking, seems useless, as the sprayer is equipped with comfortable shoulder straps.

PROS

  • a powerful battery;
  • the maximum pressure of 60 psi;
  • eight nozzles included;
  • a steel wand is durable and chemical-resistant;
  • compatible with a broad spectrum of chemicals;
  • convenient shoulder straps.

CONS

  • it is expensive;
  • the cart included is excessive.

TABOR TOOLS N-80, 2-Gallon Lawn and Garden Pump Pressure Sprayer

Review:

TABOR TOOLS offers a compact 2-gallon backpack sprayer that is perfect for the use on lawns and in small gardens. This is a classic piston pump with a plastic wand and a single nozzle. It is compatible with most fertilizers, herbicides, and pesticides, except for those with solid or abrasive components. It is lightweight and easy to carry over the shoulders. Thanks to the shut-off valve, you can keep your hands free and enjoy a consistent pressure of up to 40 psi.

What we think:

Taking into account the sprayer’s affordability, we have no major complaints about it. You just get what you pay for. On the plus side, it is lightweight and easy to use/refill/store. On the minus side, the wand is plastic and no extra nozzles are included.

PROS

  • compact and lightweight;
  • one of the cheapest options around;
  • a multi-purpose sprayer;
  • a shut-off valve;
  • a good pressure range.
  • only one nozzle.

CONS

  • the wand is plastic;

  • a good pressure range;
  • reliable and durable.
