Robotic lawn mowers are transforming the way we care for our gardens. With the touch of a button (or a swipe in an app), homeowners can enjoy a perfectly trimmed lawn without the noise, hassle, or time commitment of traditional mowing. These smart devices offer a blend of convenience, efficiency, and cutting-edge technology that’s hard to ignore—especially for those seeking a neater garden with minimal effort.
Among the rising stars in this category is Segway’s Navimow range. Known globally for their innovation in personal mobility, Segway has brought the same precision and engineering to robotic mowing. Their Navimow models stand out for being entirely wire-free, meaning there’s no need to install boundary wires. Instead, they use GPS and smart tech to create virtual cutting zones, making installation easier and more flexible.
In this article, we’ll take a close look at two popular models in the Navimow range: the i105E and the i108E. While both share many of the same intelligent features, key differences in capacity and performance make each better suited to different garden types and user needs.
If you’re a homeowner looking for a smart, wire-free mowing solution, this comparison will help you decide which Navimow model is the right fit for your lawn.
Before diving into what sets the i105E and i108E apart, it’s important to recognise the advanced features they both share. As part of Segway’s innovative i-Series range, the i105E and i108E are built on the same smart technology platform—offering premium performance, user-friendly operation, and a wire-free mowing experience.
One of the most compelling features of both models is the virtual boundary line technology. Unlike many robotic mowers that require the tedious installation of physical boundary wires, Navimow mowers use intelligent positioning systems to map out and adhere to virtual zones. This wire-free design not only simplifies setup but also allows for easy reconfiguration if your garden layout changes.
Both the i105E and i108E come equipped with a suite of smart mowing features that maximise efficiency and safety:
Planned Cutting Route: Instead of moving randomly, these mowers follow an intelligently mapped route to ensure consistent and thorough coverage.
Automatic Charging & Dock Return: When the battery runs low, the mower automatically returns to its charging dock, then resumes mowing once recharged—no manual intervention needed.
VisionFence Obstacle Avoidance: Using advanced sensors, the mowers can detect and navigate around obstacles, helping protect both the mower and your garden décor.
Blade Halt Sensor: This crucial safety feature stops the blades instantly if the mower is lifted or tilted, enhancing protection for pets and people.
Edge Cutting: Designed to trim right up to the boundary, this function helps keep your lawn looking sharp and well-maintained.
Staying connected is effortless with Bluetooth and Wi-Fi, and for those who want even greater flexibility, an optional 4G module can be added. Through the dedicated mobile app, users can take full control of their mowing schedule and settings, including:
Cutting Height Adjustments
Real-Time Status Updates
Anti-Theft Radar (to help track the mower if moved from its set area)
Segway has engineered both models for long-term resilience and performance:
Off-Road Tyres provide excellent grip on uneven terrain.
Large 24.5cm / 9-inch Front Wheels offer improved manoeuvrability and navigation across your lawn.
IP66 Waterproof Rating ensures reliable operation in all weather conditions.
Low Noise Emissions (58 dB(A)) make the mowers ideal for quiet neighbourhoods.
30% Maximum Slope Gradient allows effective mowing on slightly inclined lawns.
Automatic Weather Detection utilises local weather data to suspend mowing during rain or adverse conditions, protecting both the mower and your lawn.
Finally, both the i105E and i108E share the same compact and practical design. Each unit measures 545 x 385 x 285mm and weighs just 10.9kg, making them easy to handle during setup or maintenance.
If you’re working with a smaller lawn but still want the convenience and intelligence of a high-end robotic mower, the Segway Navimow i105E is a strong contender. Packed with the same advanced features as its larger sibling, the i105E is purpose-built for compact to medium-sized gardens, offering precision mowing without unnecessary power or expense.
With a recommended cutting area of up to 500m², the i105E is the perfect fit for suburban gardens, townhouses, and smaller detached properties. This is the model’s most significant differentiator: it delivers excellent results in more modest spaces without paying for capacity you’ll never use.
Despite its smaller size, the i105E doesn’t skimp on performance:
2.55Ah Lithium Ion Battery Capacity
Up to 60 Minutes of Continuous Mowing per Charge
Fully Recharges in Just 90 Minutes
This efficient battery cycle means the mower can easily complete its route with minimal downtime, especially in smaller gardens where a single charge may cover the full area.
The i105E offers plenty of flexibility for different grass types and seasonal changes:
Cutting Height Range of 20-60mm, adjustable manually to suit your lawn’s needs.
180mm Cutting Width, providing a good balance between speed and precision for smaller plots.
The i105E is ideal for homeowners with smaller, more manageable lawns who still want access to cutting-edge mowing technology. It’s perfect for those who don’t want to overspend on mowing capacity they’ll never fully utilise, yet still value the premium features like app control, VisionFence, and edge trimming. If your garden is compact but you’re not willing to compromise on smart functionality, the i105E is a solid, cost-effective choice.
For those with more expansive outdoor spaces, the Segway Navimow i108E offers all the intelligence and convenience of the i105E, but with added power and endurance. It’s designed to take on larger lawns with ease, making it the ideal solution for homeowners who need a bit more from their robotic mower.
The standout difference is capacity. The i108E is recommended for gardens up to 800m², offering a significant upgrade over the i105E. If your lawn is larger than average or features multiple zones, the i108E is built to handle the extra workload without compromising on performance or coverage.
To support its extended range, the i108E is equipped with a larger, more powerful battery:
5.1Ah Lithium Ion Battery Capacity – exactly double that of the i105E.
Up to 120 Minutes of Continuous Mowing per Charge – again, double the runtime.
180 Minutes to Fully Recharge – proportionate to its battery size, keeping it just as efficient in its cycle.
This expanded capacity ensures the mower can complete more extensive routes with fewer interruptions and less frequent charging, making it ideal for larger properties.
In terms of cutting mechanics, the i108E mirrors the i105E:
Cutting Height Range of 20-60mm, manually adjustable to accommodate varying grass types and seasons.
180mm Cutting Width, offering the same level of precision and speed, just applied to a broader area.
The i108E is perfect for homeowners with larger gardens who want extended mowing time and robust performance. If your lawn stretches beyond the limits of the i105E, the i108E’s increased battery capacity and runtime make it the better long-term investment. You’ll benefit from all the same premium features—wire-free navigation, app control, obstacle avoidance—but with the added confidence that your mower can keep up with the size and demands of your outdoor space.

With both the i105E and i108E offering the same advanced technology and smart features, the right choice largely comes down to garden size, usage habits, and long-term value. Here’s how to decide which model fits your needs best:
This is the single most important factor when choosing between the two models.
Under 500m²: The i105E is the clear and more economical choice. It provides all the functionality of the i108E but at a scale that matches smaller gardens. There’s no need to pay for mowing capacity that you’re unlikely to use.
Between 500m² and 800m²: The i108E becomes the logical option. While the i105E can mow larger lawns, doing so would require more frequent charging and longer mowing sessions. The i108E’s larger battery and extended runtime ensure a smoother, more efficient experience for larger spaces.
How often you mow—and the type of lawn you have—also plays a role.
If your grass grows quickly or tends to be thick and lush, the i108E’s longer mowing duration could be beneficial even for lawns just below 800m². The additional runtime allows for more thorough coverage in a single session, reducing the overall time needed to maintain your lawn.
On the other hand, if your lawn is lighter or you plan to mow more frequently in shorter sessions, the i105E may still be perfectly suitable, provided your garden stays within its capacity range.
The i108E carries a higher price tag due to its larger battery and increased mowing capacity. If your lawn is firmly under 500m² and budget is a major factor, the i105E delivers excellent value without compromising on premium features.
However, if your lawn is on the larger side—or you value longer runtime and fewer charging cycles—the extra investment in the i108E could pay off in day-to-day convenience.
It’s also worth thinking ahead. If your garden is close to the 500m² limit, or if you plan on redesigning or expanding your outdoor space in the future, opting for the i108E now may save you the hassle of upgrading later. The additional capacity provides peace of mind and flexibility as your needs evolve.
Both the Segway Navimow i105E and i108E are outstanding choices, packed with smart features, durable design, and the convenience of wire-free mowing. Whichever model you choose, you’re investing in a premium robotic mower that will take the hassle out of lawn care and keep your garden looking its best.
The key difference between the two comes down to cutting capacity and battery performance. If your lawn is under 500m², the i105E is a perfect fit—efficient, cost-effective, and more than capable. For lawns between 500m² and 800m², the i108E is the better long-term solution, delivering extended coverage and longer runtime without compromise.
To make the right choice, we recommend measuring your lawn accurately. Knowing your true garden size is the most important step in matching your mower to your needs.
Whichever model you go with, you’ll enjoy the freedom, precision, and time-saving benefits that only a Segway Navimow robotic mower can deliver. Say goodbye to weekend mowing chores—and hello to a smarter, greener future.
