Weeds are something we all try to keep down in our gardens, lawns, or driveways. They grow anywhere, whatever the climate. A high-quality backpack sprayer can make your life a lot easier.
It is a back-breaking job and all too time-consuming you can almost be weeding daily. There is nothing more disheartening than weeds growing better than our plants and flowers or making the lawn and driveway look unkempt. Small weed killer sprays do the job, but after a few sprinkles, your hand aches, and the contents get used up fast, making it expensive.
A backpack sprayer can make your life so much easier, has no backache at the end of the job, takes less time, and has many uses around the garden. Insecticides, herbicides, and plant supplements can all be done effectively and efficiently with a backpack sprayer.
When choosing a backpack sprayer, you soon come to realize there are many aspects to look at, such as types of nozzles, does it have a shoulder strap, does it have a comfortable handle, what chemicals can be used, area coverage, size of the tank; the list is endless.

Backpack Sprayers Buyers Guide
There are two types of backpack sprayers for you to choose from, motorized or manual pump action. We have reviewed both, and each has its pros and cons.
Firstly, consider how often you will use the sprayer. The motorized sprayer is more expensive, but if used daily for an hour or more, it can save you time and effort, whereas the manual pump sprayer would be more economical if used only 2 to 3 times a week for, say, 20 minutes.
Secondly, look at how much area is to be sprayed. If you have an acre or more or a large garden and driveway, a 4-gallon tank would be ideal, but if you have a more miniature garden and driveway, you could save time and money on a one or 2-gallon tank.
Maintenance
With sprayers that have high-quality Viton seals, very little maintenance is required. If you look after your sprayer, clean the tank out well, store it upside down to dry out completely, then there is no reason why your sprayer wouldn’t last a very long time.
Warranty
All the products reviewed come with a warranty and good customer service teams.
Please note: For residents living in California, the California 95 rule applies.

For recreational use, all of the products reviewed would do a good job. If you don’t like the idea of pumping manually then Scott’s Lithium-ion battery-powered sprayer would be worth considering.
