It's slower and louder than typical models, but its cleanup performance is hard to beat. Robotic mowers almost always leave the clippings on the lawn, but the Anthbot N8 does it differently. It collects grass and leaves and deposits both at a location of its choosing. This means it's not just another variant of a mulching mower, but a machine for yard owners who prefer a tidy lawn. At 24 inches long, the body itself is still manageable. With the grass catcher attached, the robot measures just under 3.3 feet.
