High-Performance Wire-Free Robotic Mowing for Large Lawns
The Segway Navimow X3 Series Robot Lawn Mower brings autonomous, wire-free lawn care to larger and more complex properties.
Built around Segway's advanced EFLS 3.0 positioning system, the X3 Series combines RTK satellite positioning, VSLAM, visual inertial odometry, and vision technology for precise navigation without requiring a physical perimeter wire.
A powerful six-blade cutting system, 300° vision-based obstacle detection, ultra-fast charging, systematic mowing, and app-based multi-zone management allow the X3 Series to efficiently maintain lawns ranging from approximately 0.5 acre to 2.5 acres, depending on the selected model.

No Perimeter Wire Required
The Navimow X3 Series eliminates the need to install a traditional physical boundary wire around your lawn.
Using EFLS 3.0, the mower navigates using virtual boundaries created during setup through the Navimow system.
This allows lawn boundaries, mowing zones, off-limit areas, and travel channels to be configured digitally rather than through buried perimeter wiring.
Virtual lawn maps can also be modified as landscaping or mowing requirements change.
EFLS 3.0 Precision Navigation
Segway's EFLS 3.0 combines multiple positioning technologies to provide precise and reliable navigation.
The system incorporates:
-
RTK satellite positioning
-
Triple-frequency observation
-
VSLAM visual positioning
-
Visual Inertial Odometry (VIO)
-
Vision-based navigation
Together, these technologies help maintain positioning accuracy in more challenging environments where satellite reception alone may be limited.
The X3 Series also supports compatible dual-antenna configurations for complex properties where additional RTK coverage may be beneficial.
AI-Assisted Mapping
The Navimow X3 Series uses AI-assisted mapping to simplify initial lawn setup.
The system can help identify lawn boundaries and create an initial mowing map without requiring physical perimeter-wire installation.
Through the Navimow app, users can configure:
-
Mowing zones
-
Virtual boundaries
-
Off-limit areas
-
Channels between lawn sections
-
Mowing schedules
-
Mowing preferences
This allows the X3 Series to manage complex properties containing multiple lawn areas.
300° Vision-Based Obstacle Detection
The X3 Series uses a 300° RGB + ToF vision system to identify and navigate around objects encountered while mowing.
The expanded field of view provides the mower with broad awareness of its immediate surroundings.
The system is designed to recognize common obstacles and help the mower safely adjust its route around people, pets, landscaping features, and other objects.
Obstacle-detection performance can vary depending on object size, lighting, visibility, terrain, and environmental conditions.
Small, hazardous, fragile, or easily damaged objects should still be removed from the lawn whenever practical.
Six-Blade Cutting System
The X3 Series uses a six-blade cutting system designed for efficient mowing across larger lawn areas.
An anti-clogging cutting disc helps reduce the accumulation of grass clippings around the cutting system.
Cutting Width
9.3 inches
Cutting Height
Adjustable from approximately:
2 to 4 inches
The appropriate cutting height depends on grass type, seasonal conditions, lawn health, and desired appearance.
Avoid removing excessive grass height during a single mowing session.
Large-Lawn Mowing Efficiency
The X3 Series is designed to cover substantially larger areas than Segway's smaller Navimow models.
Ultra-fast charging allows the mower to recharge and return to work quickly during longer mowing sessions.
The mower automatically:
-
Follows its configured mowing plan.
-
Returns to the charging station when additional battery power is required.
-
Recharges.
-
Returns to the lawn.
-
Resumes mowing until the scheduled work is complete.
Actual mowing capacity depends on lawn layout, grass conditions, terrain, obstacles, mowing settings, weather, and other environmental factors.
Slope Capability
The Navimow X3 Series is rated for working slopes up to approximately:
50% (27°)
Segway specifies maximum slope performance at a boundary of approximately:
25%
Actual traction and slope performance depend on terrain, grass condition, moisture, soil, mower orientation, and other environmental factors.
Multi-Zone Management
Multiple lawn areas can be managed through the Navimow app.
Users can configure individual mowing zones, virtual boundaries, off-limit areas, channels, and mowing schedules.
For extremely large properties, multiple compatible Navimow X3 units can also be managed through the Navimow ecosystem.
This provides additional flexibility for estates, large residential properties, and other expansive lawn environments.
Automatic Charging and Resume
When battery capacity becomes low during mowing, the X3 Series automatically returns to its charging station.
After sufficient charging, the mower can return to the lawn and continue its scheduled work.
Charging and mowing times vary by model, with larger X3 models providing increased runtime for larger lawn areas.
Quiet Operation
The X3 Series operates at approximately 60 dB(A).
Its relatively low operating noise allows automated lawn maintenance with considerably less noise than conventional gasoline-powered mowing equipment.
Local restrictions regarding lawn-equipment operating hours should still be followed.
App Control and Connectivity
The Navimow X3 Series supports:
-
Bluetooth
-
Wi-Fi
-
4G connectivity
-
Navimow app control
-
OTA software updates
The Navimow app provides access to mower setup, mapping, mowing schedules, operating status, zone management, system settings, and other supported features.
Available functions may change through software and firmware updates.
Anti-Theft Protection
The X3 Series includes multiple anti-theft features, including:
-
GPS theft tracking
-
PIN-code protection
-
Anti-theft alarm
-
Mower-lifted alerts
Connectivity and account configuration may be required for certain remote anti-theft features.
Weather-Ready Design
The mower carries an IP66 protection rating, providing resistance to dust and water under the conditions defined by that rating.
The system is designed for outdoor lawn maintenance and includes weather-aware functionality to help manage mowing under changing conditions.
The charging station, power supply, electrical connections, and other system components should always be installed and maintained according to Segway Navimow's instructions.
Expansion Capability
The Navimow X3 Series incorporates an Expansion Bay designed to support compatible accessories and additional functionality.
Segway developed the platform to allow the X3 Series to expand beyond basic robotic mowing as compatible accessories become available.
Accessory compatibility and functionality depend on the particular X3 model, accessory, software version, and regional availability.
Accessories are sold separately unless specifically included with the purchased configuration.
