The NexLawn ViDAR 1600 is a robotic lawn mower designed for gardens up to 1600 square meters. It uses a navigation system that combines 3D LiDAR (a technology that uses laser pulses to map the environment) and AI vision, eliminating the need for perimeter wires or an RTK (Real-Time Kinematic) antenna, which are commonly used in similar devices. The mower has a cutting width of 20 cm and an electric height adjustment system that allows the user to set the cutting height between 30 mm and 100 mm. It can operate on slopes up to 50%, and it includes anti-theft features like a sound alarm, PIN code access, and a position lock. The device also has GPS functionality and can be equipped with an optional shelter. However, it is not designed for mowing in the rain, though it supports water jet cleaning for maintenance. The NexLawn ViDAR 1600 is technically similar to the Mova LiDAX Ultra, sharing features like general design, charging stations, control systems, and navigation methods. The ViDAR line includes two models: the ViDAR 800, suitable for up to 800 square meters with a 72 Wh battery, and the ViDAR 1600 with a 90 Wh battery. Both models use a 360° 3D LiDAR and stereo vision for navigation. The ViDAR 1600 offers a more precise cut, finishing within 3 cm of the garden's edge, compared to the LiDAX Ultra's 5 cm margin. It also includes real-time tracking and an out-of-map alarm, features not standard on the LiDAX Ultra, which requires an extra 4G module for similar functionality. The NexLawn ViDAR 1600 comes with a charging station, power supply, eight stakes, a cleaning brush, and replacement blades. A garage is an optional accessory. Installation is similar to the Mova LiDAX Ultra, requiring a flat surface for the charging station with enough space and good Wi-Fi coverage. Configuration involves scanning the robot’s QR code, activating Bluetooth mode, and connecting to a Wi-Fi network. The user interface is similar to that of the Mova LiDAX Ultra, with the same limitations regarding grass height around the charging station. The robot's control panel resembles that of the LiDAX Ultra, featuring a central dial, buttons to start and return to the base, and a prominent stop button. Most operations are managed through a smartphone app, which includes features like map display, settings, menu navigation, and the ability to select multiple areas, set cutting height or direction, create restrictions, and access a detailed history of mowing sessions. Zone personalization allows users to set different mowing directions and activate a cross pattern to create a checkered appearance. Obstacle-related settings allow users to enable or disable recognition, set the height from which the robot should react to obstacles, and define the distance of circumvention. During testing, the robot had difficulty with small obstacles like a wooden board and a lemon, but it successfully recognized a larger barrel. The robot’s behavior with obstacles was somewhat inconsistent, with small items being its main challenge. Its large ribbed wheels offer good traction on the lawn but can leave marks on loose soil. The NexLawn ViDAR 1600 shares many features with the Mova LiDAX Ultra, including RTK-free installation, precise mapping, systematic navigation, and a feature-rich app. Its mowing quality is strong, and the ability to personalize zones makes it adaptable to slightly complex gardens. NexLawn adds features like a more precise edge finish and integrated real-time tracking. However, the robot still struggles with detecting small obstacles, and its wheels can damage loose soil. Despite these minor issues, the ViDAR 1600 is a strong competitor, and the inclusion of additional accessories and support from a specialized network could give it an edge over the Mova LiDAX Ultra. The Navimow i208 LiDAR is another excellent alternative that should not be overlooked.
