As we already mentioned in our buying guide, picking the right backpack sprayer depends on your needs and expectations.
Based on the size of the land you wish to fertilize or clean from pests, you need to know the difference between a commercial backpack sprayer and a pro backpack sprayer. The former usually feature smaller tanks and are manually operated, while the latter use batteries and can spread more product on a larger surface.
You also want your backpack to be comfortable to carry on, so you should look for products with adjustable padded shoulder straps. The wider the straps, the less pressure will be put on your back and spine.
A good filtration system is necessary if you want to prevent clogging during use and changing the pump too often. Lastly, look for a backpack garden sprayer that is made of durable and sturdy materials that won’t corrode when getting in contact with chemical compounds.
