Stop Pulling Weeds - Prevent Them!

Tertill controls weeds all season long with scrubbing wheels and a string trimmer. Simply place the robot in a weed-free garden to start, push the button and let the robot take care of the weeds.

Each robot can maintain up to a 200 sq. ft. garden. Simple requirements include 4-inch barrier, plants & rows spaced a foot apart, and a relatively flat and smooth surface.
