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.
