Buying Guide: What to Look for in a Navimow Mower for Poor GPS Signal
RTK+Vision Fusion Technology
The primary feature that sets Navimow apart from many competitors is its fusion of RTK satellite corrections with a forward-facing camera. This vision system identifies visual landmarks and edges, allowing the mower to continue navigating even when the GPS signal weakens under tree canopies or in narrow corridors. Both the i105N and i210 AWD employ this technology, but the i105N uses the enhanced EFLS 2.0 system for even more stable positioning in challenging layouts. If your lawn has many obstacles or tight passages, this is the feature to prioritize.
All-Wheel Drive vs. Single-Wheel Drive
The i210 AWD comes with all-wheel drive and automotive-grade electronic stability control, making it ideal for slopes up to 45% (24°) and uneven terrain. The i105N is a single-wheel drive model designed for flatter, smaller lawns. When poor GPS signal is combined with steep hills, the i210 AWD’s traction and stability help maintain consistent cutting without slipping. For yards with complex terrain and signal issues, the AWD model is a safer choice. Read more about Navimow mowers for complex terrain to see how these models compare.
Battery Runtime and Coverage Area
Battery life directly affects how much ground the mower can cover on a single charge, especially if it must navigate around signal black spots. The i105N covers up to 1/8 acre, while the i210 AWD covers about 0.25 acre (2,690 ft² per charge). The i210’s on-demand drive system saves power when extra traction is not needed, extending runtime. If your lawn is larger and has poor GPS zones, a longer runtime helps the mower complete the job without frequent recharging interruptions.
Obstacle Detection and Safety
Poor GPS signal often correlates with more obstacles like trees, garden furniture, or play structures. The i105N uses a 140° field-of-view camera with AI that recognizes over 150 types of objects. The i210 AWD relies on RTK+Vision but does not list a specific obstacle detection count; its all-wheel drive and stability control help it navigate around objects. For yards with many potential collisions, the i105N’s advanced AI obstacle avoidance provides extra peace of mind.
