Buying Guide

Shopping is always an uphill struggle, especially when it comes to household tools and devices. Backpack sprayers are not the exception.

The best item should meet the demands for flexibility, lightweight construction, portability, easy applications, and budget-friendliness. Your product should also require minimum maintenance and care so that you can use it with ease and comfort.

If you are struggling to get one, here are some tips that you should not ignore:

Types Of Backpack Sprayers

Each type of sprayer is suitable for specific gardening purposes, so you need to identify your demand before picking up one. In general, backpack sprayers come in two main categories: manual and motorized.

The former tend to work best for those on a limited budget, yet the manual operation is laborious and not always welcoming to some users. On the other hand, the latter model comes with powerful and handy batteries, making it easier and more convenient when you are not near the power source.

Besides, those products can be categorized based on the bump type: piston and diaphragm. Piston-powered ones offer excellent pressure, up to 90 PSI. Those units come at such an affordable price, yet they are not always suitable for all chemicals, especially harsh ones.

Meanwhile, diaphragm models can significantly stand the chemicals’ impact, supplying faster pressure. The problem is that they require more maintenance. Overall, a piston pump will be perfect for overhead spraying, while a diaphragm unit is suitable for medium PSI.


As you need to wear the backpack on your shoulder during working, comfort should always be crucial. There are several elements to look for to diminish shoulder fatigue.

Don’t forget to look for adjustable and paddled straps with an excellent fit tank. Padded waists, shoulders, and chest straps will allow you to work for hours on end comfortably.

Capacity And Power

Depending on the garden scale, you need to check the units’ capacity and power level to meet your spraying demands. For example, a professional-grade sprayer tends to generate a pressure level of up to 150 PSI, while most standard ones supply approximately 95 PSI.

Nozzle Types

In general, there are three main nozzle types: flat fan, cone sprayers, and streaming nozzles. Each comes with its own pros, so failure to choose the right nozzle can lead to chemical waste and ineffective pest control.

Flat fan and cone spray are the two most commonly used ones, available in various colors and designs. Those two nozzles allow for focused spraying patterns which are ideal for small-scale gardening projects.

The last nozzle type supplies solid streams and continuous chemical spraying, thus suitable for large gardens and high lawns.


Undoubtedly, a high-quality spray backpack comes with durable tanks made of high-density and premium polyethylene. Those tanks will surely stand the test of time and are not easily damaged by accidental droppings.

Polyethylene tanks also feature overwhelming UV protection for extra durability and safety, as they save the interior content from the direct harmful sunlight. However, the more durable the materials are, the heavier the unit becomes.

Therefore, don’t forget to decide between weight and durability to get the best one.

Maintenance Requirements

A backpack sprayer is surely a long-term investment; so, it is worth taking great care of your model. The most crucial maintaining step is to clean the sprayer with freshwater or a commercial cleaner carefully to extend its lifespan.

During the cold season, store the unit in an anti-freezing place and lubricate the seals with O-rings about twice a year for smooth operation.
