Chops down sprouted weeds with string trimmer. Easy set up - No Programming or mapping - just push the button. Proven as effective as hand weeding by the Cornell School of Agriculture. Uses height to tell plants from weeds - comes with guards to protect small plants. Weeds in 2-5 minute intervals for 1-2 hours a day. Maintains up to a 200 square foot garden. Tertill was created by the inventor of Roomba by iRobot. Garden Requirements: Barrier At least a 4-inch barrier all the way around the garden to keep it from wandering away. Metal, wood and masonry work best. Spacing Plants and rows should be 9-12 inches apart to give the robot room to maneuver. Tertill can only weed where it can reach. Surface Relatively flat surface (<7degrees) that has been raked fairly smooth to remove large rocks and ruts. A leaf rake works great! Guards Use included metal guards to protect young plants or seedling until they grow tall enough for the robot to sense them.
