The WORX WA0229 AeroCart Water Bag allows you to move water around where you need it. Go ahead and water those plants in the back of the yard without unraveling the entire hose or take some clean water to the camp site. The Aerocart Water Bag Holds up to 20 Gallons of water. That is 160 pounds of water, now easily transportable with the Aerocart Water Bag.
