LawnBott Spyder LB1200 Robotic Lawn Mower
The LawnBott LB1 1200 Spyder Robotic Cordless Electric Lawn Mower doesn’t need perimeter wire to tell it where to mow. Instead, it uses sensors which guide it across your lawn wherever there’s grass. If you have clear and precise boundary areas, this mower will do the job, but if your yard meets other yards without a dedicated boundary, it may keep on mowing.
Lawnbott can climb a 25 degree incline and weighs only 24 pounds. However, it will only cut about one eigth of an acre so it only works on small yards, at best. If you have a lot of uninterrupted lawn, this mower is tops. Just make sure there is no drive or sidewalk in the way as it won't find its way back to the charger.
