How does it tell plants from weeds?

Anything tall enough to touch Tertill's sensors is a plant. Anything short enough to go under the robot is a weed. Included guards protect young plants and seedlings. Must be placed in a weed-free garden to start then Tertill will keep it that way!

YES!! Tertill has been proven as effective as hand weeding by the Cornell School of Agriculture and we have a patent on this new way to weed.

What kind of gardens does it work in?

Gardens have to have a min 4-inch border, be relatively flat and smooth, and about a foot between plants to allow the robot to maneuver. Ideal for vegetable gardens, ornamental gardens, and herb gardens. Not recommended for cottage gardens or slopes.

What if I have a question?

You can contact the manufacturer Tertill. They offer unlimited technical support.

Replacement Strings for Tertill Weed Whacker

The only wear component on my Tertill. I check them every two weeks and replace once a month or so. Easy pull out and insert in design. Tertill actually comes with a few so you may not need any the first year. Glad they are available on Amazon for convenience.

Glad they sell this on amazon

When I bought my Tertill, it worked for one season just fine. The next year, it didn't seem to be working, so I checked underneath and found it the string whacker was totally worn out.While I knew there were a lot of spare parts that came with the Tertill, I couldn't find where I put them.So I finally gave up looking around the house and ordered a kit on amazon. I was finally able to put in a replacement string.
