McCulloch ROB S400 Robotic Lawn Mower – Cuts up to 400 sq m, Manicured Lawn, Tackles 35 Percent Slop Gradients, Lawn Growth Sensors, Simple Set Up, Intuitive Keypad

The McCulloch ROB S400 covers gardens up to 400m² with a Lawn Shield adaptive cutting system that automatically adjusts the mowing schedule based on how quickly your grass is growing — so it works harder in summer and eases off when growth slows. The flexible charging station positioning means you have more freedom in where you set up the base.

Guide wire technology improves navigation in complex gardens, helping it find its way home cleanly without leaving tracks. Installation is guided by a step-by-step setup wizard, and the intuitive keypad gives direct access to schedules and special mowing programmes without needing an app. It operates at a measured 56dB — quiet enough to run without disturbing the garden.
