The Ultimate Garden Tool - From the Inventor of Roomba®

  • Drew W.

    "This is the first time in 32 years that I have come home from vacation to a beautiful garden, rather than a weedy mess. Thanks Tertill!"

  • Dr. Averill, Cornell University

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

  • Antoinette

    "This robot is for everyone who loves gardening but hates the weeds. I think this is an excellent tool. It saves time, effort, sweat, and muscle aches. I HIGHLY recommend it."

  • Ross Trethewey - This Old House

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

But How Does It Work?

Tertill is Ridiculously Easy to Use!

Just press the button and let the robot take care of the rest. The only maintenance is to replace the whacker string when it wears down. Proven as effective as hand weeding by Cornell School of Agriculture and loved by Tertill owners in every state! ****Four Stars on Amazon ****
