Time is a finite resource. We only get so much of it, and you can't buy more — but you can take some back by ridding yourself of unnecessary chores. Like mowing the grass. The Worx Landroid M is a robotic lawn mower that will automatically cut grass, letting you spend your time on more rewarding pursuits. Depending on the model, it can cut up to a 1/2 acre, with a companion app that suggests a customized mowing schedule. Its offset cutting disc allows it to get closer to the edge than other mowers, meaning there's less trimming to do afterward, and it features automatic rain detection, so it won't try mowing wet grass. It automatically returns to its charging base when its 20V Power Share battery runs low, can tackle slopes up to 20º, and has advanced obstacle avoidance, so you won't need to place boundary wire around every tree or post.
