The Water Injected Lawn Aerator is similar to the Lawn Turf Aerator but with some added features. It allows for your garden hose to connect to your aerator. When it's connected, turn water on high, then with your foot push the tips of the aerator into your lawn until the footplate rests on the soil. Leave the aerator in the soil until foamy, bubbly water rises to surface. It should make a ring of soft, aerated water several feet in diameter. Repeat until all areas of your lawn are aerated.
