Yard work tools that save time

Like a Roomba for your lawn, this low-noise mower creates "carpet-like" lawns without anyone breaking a sweat or needing ear plugs. GPS-assisted navigation works with boundaries established by the user, and guide wires keep the mower from going rogue. All a user has to do is connect the mower to a smartphone via the Automower Connect app and give it commands. This particular model mows up to 1.25 acres, but smaller models of Husqvarna's automowers with fewer features start at $1,999. And don't worry about a passerby swiping this $3,499 machine -- it has an anti-theft alarm and a tracking device.
