Product: Tertill Garden Weeding Robot - Prevents Weeds in Vegetable Gardens, Solar-Powered, Makes a Great Gift
Brand: Tertill
Color: Green
Relevance: Substitute
Tertill the weeding robot is designed for people who want to grow their own fresh healthy vegetables – without all the weeding. Simply place Tertill in your vegetable garden (see requirements below), press the button and let the robot take care of the rest. Now you can enjoy taking care of your plants while Tertill takes care of the weeds!
EASY TO USE – Place Tertill in any garden that meets the requirements, press the button once to wake it up, and again to make it go. From the inventor of Roomba.
GARDEN REQUIREMENTS – 4-inch (or higher) border, a foot between plants or rows, a relatively flat (slope of less than 7 degrees), and relatively smooth surface. Place Tertill in a weed-free garden to start. Each robot can maintain up to 200 sq. ft.
PLANTS vs WEEDS – Tertill uses height to identify plants from weeds. Anything tall enough to touch its front sensors is considered a plant and Tertill will turn away. If it passes under the robot, Tertill cuts it. Included plant guards protect desired seedlings not tall enough to be detected by the robot.
STAYS in the GARDEN– Tertill never goes on vacation or has something better to do. It is weatherproof and can stay in the garden from Spring through Fall. Solar-powered, it never needs to be charged!
GREAT GIFT – Perfect for busy moms, dads, grandparents or anyone who doesn't have the time, ability or desire to weed the garden, but still wants to grow fresh healthy vegetables for their family.
