Best Knapsack Sprayer Review

We take a look at our top 3 knapsack sprayers to suit any budget.

Every homeowner wants a weed-free garden, lawn, fence or driveway. However, weeds are bound to sprout up wherever there are soil and moisture. Are weeds growing all over your yard, fence, or garden? Are bugs ruining your delicate plants?

If you are experiencing this, then it is time to spray weed and bug killers using a knapsack sprayer. This excellent tool is designed to help you in spraying herbicides, pesticides, chemicals and fertilizers on your garden, lawn, or fence. You may be wondering: which is the best knapsack sprayer for your garden? A motorized knapsack sprayer or a piston sprayer?

Motorised sprayers are excellent but they are expensive and are ideal for huge farms. For your small to midsize garden, you only require a piston knapsack sprayer. A piston sprayer uses the pressure created by pumping its handle, found on the side or top of the sprayer, to drive the liquid through the hose and lance before spraying.

Benefits of a Knapsack Sprayer

  1. Easy to set up and use.
  2. Minimal leakage.
  3. Sprays large spaces faster than hand-held sprayers.

Disadvantages of a Knapsack Sprayer

  1. Some sprayers have short straps.
  2. Not ideal for use under windy conditions.

For this review, we selected the best knapsack sprayers. We take an in-depth look at the features of each sprayer. We look at the capacity, weight, lance and hose length, and comfort. Remember, your sprayer is going to be on your back for some time, for this reason we recommend you get a knapsack sprayer with good straps and a trigger lock feature for when you need to spray continuously.
