Stop Pulling Weeds - Prevent Them

Scrubbing wheels and a string trimmer control weeds all season long. Tertill requires no charging, or programming - just 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.
