Product description

The Worx Landroid S400 is small in size but big in features. Unlike other brands that force you to buy larger models to get extra features, it comes with the same features as its bigger brothers. No need to program: it automatically determines working cycles to the actual growth rate of your grass, taking into consideration local weather, grass species, soil type, water and nutrition supply, and more. Like all other models in the Worx Landroid range, the S400 is configurable to individual needs with four unique options that include intelligent obstacle avoidance, anti-theft, temporary area exclusion, and Wi-Fi extension. Wi-Fi connected, the S400 will get updated automatically as soon as software improvements and new features will become available.
