Navimow i110N + 4G Module Access+ for Navimow i Series Review

Overview

The Navimow i110N is a boundary-free robotic lawn mower designed for medium-sized lawns up to 0.25 acres. It combines GPS-guided navigation with the included 4G Module Access+, which adds remote connectivity via cellular networks—a rare feature at this price point. This mower is best suited for tech-savvy homeowners who want a truly hands-off mowing experience without burying boundary wires.

Who Should Buy This

1. Homeowners with 1/4 acre lawns – The i110N is specifically rated for up to 0.25 acres, making it ideal for standard suburban front and back yards. If your lawn fits this size, you’ll get consistent coverage without the mower running out of battery mid-job.

2. Tech enthusiasts who hate laying perimeter wire – This mower uses GPS and RTK (Real-Time Kinematic) positioning to map your lawn. No trenching, no pegs, no wire breaks. If you’ve ever cursed a wire-bound robot, this is your upgrade.

3. Homeowners with poor Wi-Fi in the yard – The 4G module is a game-changer here. Even if your yard is a dead zone for home Wi-Fi, the i110N stays connected via cellular data. You can start, stop, and schedule mowing from anywhere with a phone signal.

4. People who want a “set it and forget it” mower – With automatic scheduling, rain sensors, and the ability to handle moderate slopes (up to 27%), this mower is for those who want grass cut reliably without weekly intervention.

Key Features Breakdown

Boundary-Free Mapping (RTK-GPS) – This uses a base station and satellite correction to create a virtual map of your lawn. The mower knows exactly where to cut and where to stop—no wires. It’s accurate to about 2 inches, which is impressive for GPS-only navigation. The trade-off? You need a clear view of the sky (no heavy tree canopy).

4G Module Access+ – This is a cellular modem that plugs into the mower. It gives you remote control via the app even when your home Wi-Fi can’t reach the yard. The module uses a standard SIM card (included with the mower) and has a small data plan. It’s a unique perk at this price—most competitors charge extra for cellular connectivity.

Cutting Width & Height – The 8-inch cutting width is narrower than some competitors (like the 10-inch Worx models), but the 1.2- to 2.4-inch adjustable cutting height range is standard. For a 0.25-acre lawn, the width isn’t a dealbreaker—it just means slightly longer mowing cycles.

Battery & Runtime – A 2.5 Ah lithium-ion battery delivers about 60 minutes of runtime. That’s enough to cover 0.25 acres in one charge, but you’ll want to plan for a recharge if your lawn is right at the limit. The mower returns to its charging dock automatically.

Slope Handling – Rated for 27% slopes (about 15 degrees). That’s solid for a robot mower—most cap out at 20-25%. If your yard has a gentle hill, this mower won’t get stuck.

Rain Sensor – The mower detects rain and returns to the dock. It’s a basic but essential feature that prevents it from churning up muddy ruts.

Pros

• No boundary wires to install – Saves hours of setup time and eliminates future wire breaks from digging or frost heave.
• 4G connectivity included – You don’t need Wi-Fi range to the yard. This is a rare, genuinely useful feature for larger properties or homes with thick walls.
• Accurate GPS mapping – The RTK system creates a reliable virtual fence. It won’t wander into flower beds like cheaper GPS mowers.
• Quiet operation – At around 58 dB, it’s quieter than a gas mower and won’t disturb neighbors during early morning cuts.
• Easy app control – The Navimow app is intuitive. You can set schedules, adjust cutting height, and create no-go zones from your phone.
• Good slope handling – 27% grade capacity means it handles most residential hills without slipping.

Cons

• Narrow cutting width (8 inches) – This mower takes longer to finish a lawn than wider models. For a 0.25-acre yard, expect 60-90 minutes per mow.
• GPS dependency – Heavy tree cover or tall buildings can cause signal loss. If your yard has a dense canopy, the mower may pause or drift.
• No mulching or bagging option – The i110N is a side-discharge mower only. It leaves clippings on the lawn (which is fine for most, but not for those who want a bagged finish).
• Price point – At $1,182, it’s more expensive than many wire-bound robot mowers. You’re paying for the 4G module and GPS convenience.

Bottom Line

The Navimow i110N is a solid mid-range robot mower that solves two common headaches: boundary wire installation and Wi-Fi range limitations. The 4G module is a standout feature that makes it genuinely useful for homes with spotty internet in the yard. It’s not the fastest mower (8-inch cutting width means patience is required), and it won’t work well under dense trees. But for a 0.25-acre lawn with decent sky visibility, this is a reliable, low-maintenance choice. I’d recommend it over wire-bound competitors if you value convenience over cutting speed.

Frequently Asked Questions

Q: Does the 4G module require a separate data plan? A: No. The module comes with a pre-loaded SIM card and includes a data plan for the first year. After that, you’ll need to purchase a data plan (Navimow offers one for about $30/year). The mower uses very little data—just for app commands and status updates.

Q: Can I create no-go zones for flower beds or walkways? A: Yes. In the app, you can draw virtual boundaries for areas you want the mower to avoid. The GPS mapping allows for multiple no-go zones, and they’re easy to adjust if you change your landscaping.

Q: What happens if the GPS signal is lost while mowing? A: The mower will pause and try to reacquire the signal. If it can’t, it will return to the charging dock. This is more common near buildings or under dense trees. For best results, ensure the base station has a clear view of the sky.
