When it comes to menial household tasks that could really use the help of a small, robotic automaton, mowing the lawns is right up there with vacuuming.While robotic vacuums have become somewhat normal, with companies like Roomba pioneering the market and major technology companies like Samsung and LG joining the fray, robotic lawn mowers represent a much less crowded marketplace.It's true that robotic lawnmowers have been around for a few years, but the Landroid from Worx is notable for its $1,199 asking price, putting it into an affordable price bracket. Powered by a 28 Volt Li-ion battery which takes about 1.5 hours to completely charge, the Landroid is technically capable of mowing a 1,000 square metre area on a single charge, although in reality it probably won't get that much mowing done.Like other robotic lawnmowers, the Landroid uses spinning razor blades to slice the top of the grass, as opposed to traditional mowers which hack the grass.The idea is that regular slicing of the grass both reduces the stress on the lawn, and as an added benefit fertilising it with the grass cuttings. But is it worth it? Does the cost of a $1,200 lawnmower pay for itself? The answer, ultimately depends on your lawn.D
