Segway Navimow X420E 2,000m² Robotic Lawnmower

A New Era of Automated Lawn Care

The Segway Navimow X420E marks a significant advancement in robotic lawn care, specifically engineered for homeowners with large, complex, and challenging gardens up to 2,000 m². This model completely does away with the need for perimeter wires, employing a sophisticated EFLS™ NRTK Positioning system for centimetre-level accuracy without a local base station. Setup is streamlined through the Navimow app, featuring Hands-Free Auto Mapping which generates a precise, real-scene map of your lawn for intuitive editing and zone creation directly on a smartphone.

Unrivalled All-Terrain Performance

Built to master demanding landscapes, the Navimow X420E is equipped with a Xero-Turn™ All-Wheel Drive (AWD) system and dual suspensions. This, combined with a 5:5 balanced centre-of-gravity, gives it the stability to handle extreme slopes up to an 84% (40°) incline with confidence. Its pioneering front-wheel steering cleverly switches between zero-turn and automotive-grade Ackermann steering to prevent any turf damage during manoeuvres. The patented Traction Control System (TCS) further enhances its capabilities by dynamically adjusting wheel torque, preventing slipping on wet or low-traction areas. It can also navigate vertical obstacles up to 7 cm high.

Advanced MowMentum™ Cutting Technology

The core of the X420E is its high-performance cutting system. A dual-disc deck with 12 blades, powered by two 180W motors, delivers a wide 43cm (approx 17″) cutting path for a professional finish, even on dense or tall grass. The cutting height can be precisely adjusted between 20mm and 95mm. The adaptive blade system allows the deck to float over uneven ground to minimise scraping, while a smart algorithm automatically lifts the blades when encountering particularly thick grass. For a perfect finish, the Edgesense™ feature provides “Zero-Distance Cutting,” mowing as close as 5 cm to walls and fences.

Intelligent and Safe Operation

The Navimow X420E uses an AI-Powered 360° VisionFence™ system for superior obstacle avoidance. Utilising triple panoramic cameras and ToF sensors, it can detect and identify a vast range of common garden objects and animals, including toys, hoses, furniture, and pets. With a 5-metre detection range and 1.8m Night Vision, it can reroute in just 0.1 seconds, always maintaining a safe distance. The system supports up to 120 customisable zones, including no-go areas, all easily managed through the app.

Durable, Smart, and Secure

Designed for longevity, the Navimow X420E has an IP66 dustproof and waterproof rating, meaning it can be easily rinsed clean. Integrated rain sensors automatically send the mower back to its charging station when the weather turns. For security, a quad-layer system ensures the mower can be located even if powered off or offline. It also features smart home voice control integration and receives seamless Over-The-Air (OTA) software updates. Users can even get creative with the “Doodle” feature, drawing patterns or text on their lawn.
