Tertill® Weeds the Garden for You

From the Inventor of Roomba®

Tertill is a compact and effective robot that weeds your vegetable garden for you. It's solar-powered, weatherproof, and lives in the garden all season long.

To Tertill, weeds are short and plants are tall. Anything tall enough to touch it's sensors makes the robot turn away, if it passes under the robot, it cuts it.

“... the result is astounding. You are seeing as good weed control with Tertill as with the hand weeding effort.”

Dr. Averill at the Cornell University School of Integrative Plant Science.

"This weeding robot will save you time and energy removing weeds automatically."

"I love this little thing. It’s so adorable! I was intrigued as soon as I came across this listing and, since we expanded our garden this year, I figured I could use all the help I could get with weeding. I love that it’s solar powered cause the last thing I need is something else to charge.

"This robot is for everyone who loves gardening but hates the weeds. It's like a robot vacuum for outside. I think the most important part of using this robot is to watch the videos first. They give you a good introduction to how it works and how best to use it. I think this is an excellent tool. It saves time, effort, sweat, and muscle aches. I HIGHLY recommend it."
