Robotic lawn mowers are getting smarter all the time. The latest models not only connect to your smartphone but also use smarter algorithms for more efficient cutting performance. Take the HOOKII Neomow S for instance: it is a parallel mowing robotic lawnmower with app control that can mow up to 300 square meters on a single charge. It features Bluetooth, 4G, and WiFi connectivity.
This robot comes with a built-in IMU and GPS. It is smart enough to remember where it stopped mowing when it needed to be charged to reduce repeated mowing. The HOOKII app lets you set mowing mode and put this robot on a schedule. The Neomow S is not only IPX5 waterproof but has rain detection sensors to avoid mowing on rainy days. It has ultrasonic sensors to avoid obstacles autonomously.[where to get it]
