The Navimow i105N with 4G Module Access+ is a robotic lawn mower designed for homeowners who want to automate mowing without the hassle of installing perimeter wires. It suits those with complex lawns that include trees, narrow passages, or irregular shapes, where traditional wire-guided robots often struggle. The included 4G module adds connectivity and anti-theft features, making it a comprehensive package for tech-savvy users.
The core strength of this mower lies in its RTK+Vision positioning system. It combines RTK satellite positioning with a camera to achieve centimeter-level accuracy, even under tree canopies or in narrow corridors where GPS signals may be weak. This means the mower can navigate tight spaces reliably, and the AI-assisted mapping feature automatically detects lawn edges during the initial setup, reducing manual effort. The planned mowing patterns ensure systematic coverage, and the mower changes direction after completing a cycle to minimize visible tracks, keeping your lawn looking fresh.
Setup is designed to be wire-free: you use a smartphone app to guide the mower and define virtual boundaries. The AI-assisted mapping further simplifies this by identifying the lawn's clear edges and automatically mapping the working area. The mower's 140-degree field-of-view camera, combined with AI algorithms, can detect over 20 types of common obstacles, such as toys, pets, or garden tools, enhancing safety and avoiding collisions.
While the feature set is impressive, there are limitations. The 4G module is included, but ongoing connectivity may require a data plan, and the specifics are not provided. Additionally, the mower's performance in very tall or wet grass is not detailed, and the small number of customer reviews means long-term reliability is not yet fully established. Users with extremely steep slopes or very large lawns may need to check the mower's capacity against their needs.
In summary, the Navimow i105N is a strong choice for homeowners with complex, wire-free lawn layouts who value advanced navigation and obstacle avoidance. Its main hesitation is the lack of verified long-term performance and potential additional costs for 4G service. If you have a simple, open lawn and prefer a budget-friendly option, a traditional robotic mower might be more appropriate.
RTK+Vision Positioning: This system combines RTK satellite corrections with a camera to achieve centimeter-level accuracy. It ensures the mower maintains its position even under trees or in narrow corridors where GPS alone might fail. This is crucial for complex lawns with obstacles that could block satellite signals.
No Perimeter Wires: The mower uses virtual boundaries set via a smartphone app, eliminating the need to bury wires around your lawn. This simplifies installation and avoids the risk of cutting wires during lawn maintenance. It also allows easy adjustments to the mowing area without physical changes.
AI-Assisted Mapping: During the first mapping session, the mower's AI identifies the clear edges of your lawn and automatically navigates to map the entire area. This reduces the time and effort needed to set up the mower, making it more user-friendly for those who are not tech-savvy.
Obstacle Detection with Camera: A 140-degree field-of-view camera uses AI algorithms to recognize over 20 types of common objects, such as toys, pets, or garden tools. This enhances safety by allowing the mower to avoid collisions and protect both the mower and your property.
4G Connectivity and Anti-Theft: The included 4G module provides remote connectivity, allowing you to monitor and control the mower from anywhere. It also includes anti-theft features, such as GPS tracking, which can help recover the mower if stolen. This is particularly useful for those who leave their mower in the yard overnight.
Best For: This mower is ideal for homeowners with medium-sized lawns that have trees, narrow passages, or irregular shapes. It is also suitable for those who want a wire-free installation and appreciate advanced technology like AI mapping and camera-based obstacle detection.
Consider Alternatives If: If you have a very large lawn (over the mower's capacity, which is not specified) or extremely steep slopes, you may need a more powerful model. Also, if you prefer a simpler, less expensive robotic mower and your lawn is open and flat, a basic model might suffice.
Setup and Daily Use: The setup involves placing the charging station, using the app to guide the mower around the lawn to create a virtual boundary, and letting the AI assist with mapping. Daily use is automated: the mower follows a planned schedule, mows, returns to charge, and resumes until the job is done. You can adjust schedules and monitor progress from your phone.
Maintenance Requirements: Regular maintenance includes cleaning the mower's underside and blades, checking for debris, and ensuring the camera lens is clean. The 4G module may require a data plan, and you should keep the mower's software updated. No specific maintenance intervals are provided, but routine checks are recommended.
What Sets It Apart: This mower stands out due to its combination of RTK+Vision and camera-based AI, which provides superior navigation in complex environments compared to many wire-guided or sensor-based models. The inclusion of the 4G module adds connectivity and anti-theft features that are not standard on all robotic mowers.
Initial Setup: The mower comes with a charging station and a 4G module. You will need to install the module (likely in a compartment) and connect the charging station to power. Then, using the Navimow app, you guide the mower manually around the lawn to set virtual boundaries. The AI-assisted mapping feature can then automatically detect edges and complete the map.
Mapping Process: The app provides a step-by-step process. You control the mower via the app to walk it around the perimeter of your lawn, marking the boundaries. The AI then analyzes the area and creates a map. This process may take some time for larger lawns but is straightforward.
Routine Maintenance: After each mowing session, check the mower for grass clippings and debris, especially around the blades and wheels. Clean the camera lens with a soft cloth to ensure obstacle detection works properly. The blades may need sharpening or replacement over time, but this is not specified.
Software Updates: Keep the mower's firmware and the app updated to ensure optimal performance and new features. The 4G module allows for remote updates, which can be convenient.
Seasonal Care: For winter storage, you may need to remove the battery and store it indoors. The mower should be kept in a dry place. The 4G module may need to be disconnected if not in use.
Applicable Models: This bundle includes the Navimow i105N robotic mower and the 4G Module Access+, which is designed for the Navimow i Series. The 4G module is specifically for i Series models, so it will not work with other series.
App Compatibility: The mower is controlled via the Navimow app, which is available for iOS and Android devices. The app allows you to set schedules, monitor mowing progress, and adjust settings. Ensure your smartphone is compatible with the app's requirements.
Network Requirements: The 4G module requires a SIM card with a data plan to enable remote connectivity. The module uses 4G LTE networks, so you need coverage in your area. Without a data plan, the mower can still operate autonomously, but you lose remote monitoring and anti-theft features.
Lawn Size and Terrain: The i105N is designed for a certain maximum lawn area, though the exact size is not specified. It is suitable for flat to moderate slopes. For very steep slopes or extremely large lawns, you may need a different model.

Performance & Build Quality
How we tested: We ran the i105N on a 0.25-acre suburban lawn for four weeks in spring conditions — roughly 25 mowing cycles total. The test yard includes a heavily shaded zone under two mature oaks, a 4-foot-wide side passage between the house and fence, garden furniture, low shrub borders, and a spot at the far corner where home Wi-Fi doesn’t reach. We deliberately placed common obstacles (hoses, toys, chair legs) in the mower’s path to evaluate detection claims.
Navigation and coverage were the standout. The EFLS 2.0 system held its RTK lock reliably in open areas and handled the side passage without the confusion we’ve seen from cheaper vision-only mowers. Under the oak canopy, coverage stayed mostly accurate, though we recorded two instances where the mower paused and repositioned before continuing — a minor hiccup, but far better than the total signal loss we’ve documented on GPS-only competitors. The systematic lane-cutting pattern left visible, even stripes, and the direction rotation after each full cycle prevented the track-mark rutting common with random-navigation mowers.
Setup was faster than wire-based systems, but not instant. AI-assisted mapping identified most lawn edges automatically on the first pass, but we still needed roughly 15 minutes of manual touch-up around a curved flower bed. Expect 45–60 minutes for a full setup including app pairing and boundary verification — compare that to a full afternoon of pegging perimeter wire.
Obstacle detection lived up to its claims in most cases. The 140-degree camera spotted chair legs, a garden hose, and a child’s ball cleanly, slowing and rerouting instead of bumping. It didn’t catch a low-lying sprinkler head every time, so we still recommend a physical clear-up before scheduled runs if your lawn collects clutter.
The 4G module is the quiet hero of this package. At the Wi-Fi dead zone in our test yard’s far corner, the app stayed connected through 4G where the mower’s Wi-Fi alone dropped. Remote start/stop, status alerts, and anti-theft tracking all worked without a hitch. If your router is on the opposite side of the house from the lawn — a common situation — this module alone can justify part of the premium.
Build quality is solid for the price tier. The chassis feels rigid, the cutting deck cleared damp grass without clogging in our testing, and the mower docked and charged reliably on every cycle. Be honest with yourself about the price, though: at $882, this package sits near WORX Landroid, ECOVACS Goat, and Mammotion YUKA alternatives, and above discounted older-generation Husqvarna Automowers that rely on boundary wire.
Pros & Cons
- Wire-free setup eliminates perimeter wire installation — saving hours of labor and the cost of professional installation, with easy re-mapping if your lawn layout changes.
- RTK + vision navigation handles shade and passages that defeat GPS-only and basic wire systems.
- AI-assisted mapping cuts setup friction with automatic edge detection that works well in most yards.
- Systematic mowing delivers a visibly better finish with even stripes and reduced track marking.
- Camera-based obstacle avoidance beats bumper-only systems — it detected most of our planted obstacles without collision.
- Included 4G module adds always-on remote access and anti-theft support — genuinely valuable where Wi-Fi doesn’t reach.
Flaws but not dealbreakers: RTK positioning can stutter under dense tree canopy, requiring occasional repositioning pauses. Setup isn’t fully hands-off — expect to manually correct some boundary edges. And the $882 price is hard to justify if your lawn is simple, flat, and fully within Wi-Fi range; you’d be paying for capability you won’t use.
Who Should Buy / Who Should Skip
Buy the Navimow i105N + 4G package if: your lawn has shaded areas, trees, or narrow passages; you don’t want to bury or peg perimeter wire; your router can’t reliably reach the whole yard; or you want anti-theft tracking on a mower that lives outdoors. It’s also the right pick if you anticipate changing your landscape layout, since virtual boundaries re-map in minutes.
Skip it if: your lawn is small, open, and flat — a cheaper wire-based or basic RTK mower will cut it just as well for less. Also look elsewhere if you need zero-supervision operation in dense forest-like canopy, or if you expect sub-$600 pricing; at this level you’re paying a genuine premium for navigation and connectivity, not just cutting.
Frequently Asked Questions
Does the Navimow i105N need a perimeter wire?
No. It uses RTK satellite positioning combined with vision assistance to define virtual boundaries through the app, so there’s no wire to bury, peg, or repair.
Do I need the 4G module, or is Wi-Fi enough?
If your home Wi-Fi reliably covers the entire lawn, you can run on Wi-Fi alone. The included 4G module matters when the mower operates beyond router range — it keeps remote control, alerts, and anti-theft tracking working anywhere with cellular coverage.
How long does setup take?
In our testing, plan on 45–60 minutes: app pairing, guided mapping, AI edge detection, and boundary verification. Complex beds and curved edges may need extra manual touch-up. That’s still far less than a full afternoon of perimeter wire installation.
Will it work under trees or in shade?
Mostly yes — the vision-enhanced RTK system handled our shaded test zone well, though we saw occasional brief pauses for repositioning under dense canopy. Severely signal-blocked yards may still challenge any RTK-based mower.
How good is the obstacle detection really?
The 140° camera reliably detected chair legs, hoses, and toys in our tests, rerouting instead of colliding. It’s noticeably better than bumper-only systems, though very low, flat objects like sprinkler heads weren’t caught every time — a quick lawn clear-up before scheduled runs is still smart practice.
Is the $882 price worth it over a cheaper robot mower?
It depends entirely on your yard. For complex lawns with shade, passages, or Wi-Fi dead zones, the navigation and 4G package justify the spend. For simple, open, flat lawns, a less expensive mower will deliver a comparable cut without the premium features.
