Perks of Being a Weeding Robot Customer
The Tertill Weeding Robot includes free standard shipping anywhere in the continental US.
60-Day Risk Free Trial
The Tertill Weeding Robot is awesome, but it is not perfect for every application. If you buy it, and it doesn't work in yours, we will gladly take it back and refund you 100% of your purchase price. We even pay for shipping it back to us. Please read the Where it Works Blog to help you decide if Tertill is right for your garden!
No one has ever made a weeding robot for home gardens, so you might have some questions. You can reach out to us at firstname.lastname@example.org and/or check out the FAQ page to see if there is a quick answer
Free Tertill App
Download the free Tertill App for Apple or Android and manage your Tertill Robot. You can even give it a name! Some of our favorites are Yertill, Romeo, Franklin, and Myrtle.
Tertill was designed by a team of world-class roboticists, including Joe Jones, the inventor of Roomba®. It has a full 1-year limited warranty which covers any product defects (failed motors, battery, etc.) that occur during normal use of your robot. In other words, stuff happens, we make it right.
Tertill is Gentle on Plants, but Fierce on Weeds
At least a 4-inch barrier all the way around the garden to keep it from wandering away. Metal, wood and masonry work best.
Plants and rows should be 9-12 inches apart to give the robot room to maneuver. Tertill can only weed where it can reach.
Relatively flat surface (<7degrees) that has been raked fairly smooth to remove large rocks and ruts. A leaf rake works great!
Use included metal guards to protect young plants or seedling until they grow tall enough for the robot to sense them.
