A Better Way to Weed

Created by the inventor of Roomba, Tertill lives in your garden, runs on sunshine, and weeds every day. Tertill keeps weeds from taking over your garden robotically, without spraying herbicides, hauling mulch, or putting down ugly plastic films. Proven as effective as hand weeding by the Cornell School of Agriculture, Tertill lets you grow your best garden yet.

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