They are like a Roomba for the garden.
There are some limitations, such as needing smooth ground without rocks or mulch. I think that they will improve them with time.
But, they are still pretty good. They are solar powered, don't touch large plants, and you can put something down to keep them from touching small vegetables, so that it doesn't mistake them for weeds.
They have a string trimmer underneath.
Success with your vegetables! How funny about Kenny, but I can't blame him. Homegrown vegetables are the best!
