Robomow RK4000 16.5 in. 9.6 Ah Lithium-Ion Robot Lawn Mower (Up to 1 Acre)

With effortless programming of up to 4 secondary zones/starting points and 2 separate zones via app, or the convenience of the touch display and adjustable cutting height, the RK1000 offers maximum flexibility. The brushless DC motor, the pendulum-suspended mower deck and the staggered blades result in an evenly trimmed lawn even on uneven terrain. Slopes of up to 45% are no problem for this robotic lawnmower. Best of all, thanks to the low noise level, you will hardly notice when the robot is in use.
