This week at MWC, Husqvarna announced its first all-wheel drive (AWD) option with the 435X. In addition to some other unique features, this new "automower" works with Amazon's Alexa and Google Home to fit in with the rest of your smart home devices. And yes, the integration with virtual assistants means you can control the robotic landscaper with your voice. AWD adds the ability to handle slopes and rough terrain better. Husqvarna says the 435X can handle an incline of up to 70 percent, which is quite steep.
