The Worx 20V Power Share 2-Gallon Cordless Yard Sprayer is a better option for regular spraying applications than hand-pump sprayers. The automatic pump uses an air compressor for a continuous spray, no hand-pumping needed. So you can apply fertilizer, weed killer, insect spray and more all day long with less strain. Plus, you can use the pump with other tanks without having to worry about contamination. Since the pump uses air to force the liquid out, it never comes in contact with the contents of the tank. What’s more, the pump has a thread that’s common amongst other yard sprayers, so it’ll work with tanks from many other brands of manual-pump yard sprayers. And while it comes with a 2-gallon tank, it’s also compatible with the Worx 5L tank (WA4028), for your convenience. As part of the Power Share platform, it uses the same batteries as every other tool, outdoor power and lifestyle product in that family. So you can purchase the Yard Sprayer model that either comes with a battery (WG829), or the model that doesn’t include a battery (WG829.9) if you have some Power Share batteries already. It’s a cost-effective way to grow your cordless tool collection when you don’t always have to buy a new battery every time you buy a new Worx Power Share tool.
