The Segway Navimow i Series is designed to provide a wire-free, autonomous lawn mowing experience, eliminating the need for traditional boundary wires. Utilizing EFLS 2.0 technology, it employs Visual SLAM for precise navigation, even in areas with weak satellite signals. This system allows the mower to create 3D maps of the lawn, ensuring comprehensive coverage. Additionally, the VisionFence™ feature enhances obstacle detection, distinguishing between grass and common obstacles like pets and outdoor equipment.
In our evaluation, the Navimow i Series demonstrated several strengths. Its quiet operation at 58 dB(A) allows for mowing at various times without disturbing household members or neighbors. The AI-assisted mapping and wire-free setup simplify the installation process, enabling users to establish virtual boundaries and customize mowing schedules through a user-friendly app. The mower’s ability to handle slopes up to 30% (17°) and its IP66 waterproof rating contribute to its versatility across different lawn conditions.
However, some users have reported challenges. For instance, the mower may struggle with navigation accuracy in certain terrains, leading to incomplete coverage or missed areas. Additionally, the initial setup, particularly the precise placement of the antenna for optimal GPS signal, can be complex and time-consuming. There are also reports of the mower not recognizing specific obstacles, such as water channels, despite virtual barriers being set.
Overall, the Segway Navimow i Series is well-suited for homeowners seeking an automated, low-noise mowing solution for moderately complex lawns. Prospective buyers should be prepared for a potentially intricate setup process and may need to monitor the mower’s performance to ensure it meets their lawn care expectations.
Autonomy Ladder™ Classification
Assigned using the Autonomy Ladder based on observed performance.
Conditional AutonomyJustification
The Navimow i Series operates autonomously with AI-assisted mapping and obstacle avoidance, handling routine mowing tasks independently. However, it requires periodic human intervention for setup adjustments, maintenance, and addressing navigation inaccuracies, classifying it as Level 3 (Conditional Autonomy).
Observed Limitations
- Cannot handle complex obstacles like water channels without manual intervention
- Requires precise antenna placement for optimal GPS signal
- May miss areas or leave uncut grass along edges
- Needs manual blade height adjustment

Reliability & Maintenance
Long-term stability and the effort required to maintain it.
Reliability Over Time
Long-term user reports indicate that while the Navimow i Series maintains consistent mowing performance, some users have experienced battery degradation after two years, leading to reduced mowing time per charge. Additionally, navigation accuracy may decline if the GPS antenna is not periodically checked and adjusted.

Failure Modes & Recovery
Where the robot struggles — and how it recovers.
- Navigation Errors: Inaccurate GPS signal or improper mapping can lead to missed areas or repeated mowing of the same section
- Obstacle Detection Failures: May not recognize certain obstacles like water channels, leading to potential damage or getting stuck
- Edge Mowing Inefficiency: May leave uncut grass along lawn edges, requiring manual trimming
- Setup Challenges: Complex initial setup, especially antenna placement, can result in operational issues
- Battery Performance Degradation: Over time, battery capacity may decrease, reducing mowing duration per charge
- Scenario: If the mower encounters an obstacle it cannot navigate around, it stops and sends an alert via the app
- Scenario: In case of low battery, the mower autonomously returns to the charging dock
- Scenario: If lifted or moved unexpectedly, the mower triggers an alarm and sends a notification
- Scenario: During adverse weather conditions, the mower pauses operation and returns to the dock
Safety & Misuse Risk
Safety observations and potential misuse risks identified during testing.
- Equipped with a child lock feature to prevent unintended operation
- VisionFence™ technology enhances obstacle detection, reducing collision risks
- IP66 waterproof rating ensures safe operation in various weather conditions
