The Navimow H Series represents Segway’s most refined take on wire-free robot mowing. Launched to succeed the earlier i and H105/H115 range, the H Series uses eSpaze GPS — Segway’s proprietary combination of satellite positioning and visual correction — to map and mow without any perimeter wire installation. For UK homeowners who balked at the prospect of burying wire around their lawn, it is a genuinely compelling proposition.
This review covers all three models in the range: the H500E, H800E, and H1000E. We compare specification, real-world performance, app experience, and value for money so you can choose the right model for your garden.
Quick Comparison Table
| Model | Max Coverage | Slope | Noise | App | Price Range |
|---|---|---|---|---|---|
| Navimow H500E | 500 m² | Up to 35% | 57 dB | Segway app | ~£800–£950 |
| Navimow H800E | 800 m² | Up to 40% | 58 dB | Segway app | ~£1,050–£1,200 |
| Navimow H1000E | 1,000 m² | Up to 45% | 59 dB | Segway app | ~£1,300–£1,500 |
All three models share the same core design, eSpaze GPS navigation, and Segway app platform. The differences are coverage area, slope capability, and battery capacity.
How eSpaze GPS Works
Unlike traditional wire-based robot mowers — which follow a buried perimeter signal — the Navimow H Series uses eSpaze, a multi-signal satellite system (GPS, GLONASS, Galileo) combined with a vision module on the mower itself. The vision system cross-references camera data with the satellite position to achieve sub-10 cm accuracy in open conditions.
Setup involves placing the base station at a fixed point in your garden and using the Segway app to walk the boundary of your lawn. The app converts your walked path into a digital map, which the mower then navigates autonomously. Total setup time for a straightforward rectangular lawn is typically 30–45 minutes.
Under heavy tree canopy, GPS accuracy can degrade, though the vision module compensates reasonably well. UK owners with part-shaded gardens report occasional boundary drift of 5–15 cm in fully shaded sections — not a dealbreaker, but worth knowing if your lawn has dense tree coverage.
H500E — Best for Gardens Up to 500 m²
The H500E is the entry point to the H Series and is well-matched to typical UK semi-detached and terraced garden sizes. Its 500 m² coverage rating should be treated as a ceiling — for best results, choose it for gardens up to around 400 m² to leave headroom.
The 35% slope rating handles most standard UK garden gradients comfortably. The cutting height range of 30–60 mm suits typical UK lawn preferences.
Runtime on a single charge covers approximately 500 m² of cutting before docking to recharge. Charging takes around 90 minutes on the standard dock.
Pros:
- Wire-free setup — no buried perimeter cable
- Quiet at 57 dB — acceptable for morning or evening mowing
- Good app experience with scheduling, zone exclusions, and remote access
- Compact design suits smaller gardens
- PIN and alarm security built in
Cons:
- 35% slope limit may not suit gardens with steeper banks
- GPS accuracy reduces under dense tree canopy
- No multi-zone support on H500E (single lawn area only)
- Base station must remain positioned year-round
Verdict: The right Navimow for most UK buyers with a standard garden up to 400 m². Straightforward setup and reliable day-to-day operation.

H800E — The Balanced Choice
The H800E steps up coverage to 800 m² and slope handling to 40%. It introduces multi-zone support — you can define separate lawn areas (front and back garden, for example) and the mower navigates between them.
The 40% slope rating covers the majority of UK garden gradients, including most ornamental banks and sloped rear gardens. The additional battery capacity extends runtime proportionally.
For buyers with a front-and-back lawn combination, or a single lawn over 500 m², the H800E is the natural choice.
Pros:
- Multi-zone support covers front and back gardens
- 40% slope handling suits most UK gardens
- All eSpaze GPS benefits of the H500E
- Good balance of price and capability
- Segway’s app support has improved significantly through firmware updates
Cons:
- Still limited under very heavy canopy
- Step up in price from H500E is meaningful
- 800 m² maximum suits medium gardens but not large ones
Verdict: The H800E is the sweet spot in the H Series range — capable enough for most UK gardens, priced fairly for what it delivers.

H1000E — Best for Larger Gardens
The H1000E extends coverage to 1,000 m², increases slope handling to 45%, and adds a larger battery for extended mowing sessions. It is the most capable Navimow available and competes directly with Husqvarna’s mid-range wire models at a similar or lower price.
The 45% slope rating is genuine — UK owners report confident performance on steep rear gardens that would challenge lesser mowers. Combined with the GPS boundary setup, the H1000E handles complex garden shapes without the hassle of routing perimeter wire around obstacles.
Pros:
- Largest coverage in the H Series range
- 45% slope handling — competitive with premium wire-based models
- Multi-zone support
- Strong app feature set including scheduled zones and seasonal programs
- Wire-free setup remains the key differentiator at this price
Cons:
- At £1,300–£1,500 it competes with established brands like Husqvarna
- GPS limitations under canopy remain
- Heavier and slightly bulkier than the smaller H Series models
Verdict: The H1000E makes a strong case at its price point for gardens up to 900 m² with moderate to good satellite visibility. It is the best wire-free option in this size bracket from Segway.

App and Software Experience
The Segway app (iOS and Android) is the control centre for all H Series mowers. The interface covers:
- Boundary mapping — drawn during initial setup via GPS walk
- Zone management — separate areas for multi-zone models
- Scheduling — day-by-day programming with time windows
- Exclusion zones — mark areas to avoid (flower beds, trampolines)
- Remote access — start, stop, and return to dock from anywhere
- Firmware updates — delivered over the air
The app has improved considerably since the original Navimow launch. Earlier firmware had connectivity issues and occasional map corruption; the current software is stable and the UI is clean. Segway’s support team is responsive to bug reports.
Installation and Setup
Wire-free setup is the H Series’s strongest selling point for UK buyers. There is no need to dig or bury cable — a task that can take a professional installer a full day and cost £150–£300.
The process:
- Fix the base station at a stable, open-sky position in your garden
- Open the Segway app and start the boundary mapping wizard
- Walk the perimeter of your lawn with the mower active — the app records your path
- Review and confirm the digital boundary map
- Set your mowing schedule
Most UK owners complete this in under an hour. For complex multi-zone layouts (H800E/H1000E), add 15–20 minutes per additional zone.
How It Compares to the Competition
| Model | Navigation | Coverage | Slope | Wire Required | Approx. Price |
|---|---|---|---|---|---|
| Navimow H500E | eSpaze GPS | 500 m² | 35% | No | ~£900 |
| Navimow H1000E | eSpaze GPS | 1,000 m² | 45% | No | ~£1,400 |
| Husqvarna 310E | GPS + wire | 1,000 m² | 40% | Yes | ~£1,000 |
| Mammotion LUBA Mini | RTK GPS | 1,000 m² | 75% | No | ~£1,200 |
The Navimow competes well on price and wire-free convenience. The Mammotion LUBA Mini edges it on slope capability, and Husqvarna’s wire-based reliability is proven over many years — but for most buyers, the Navimow’s no-wire setup is a decisive advantage.
FAQ
Does the Navimow H Series work in the rain? Yes. The mower has an IPX5 rain rating and a rain sensor. In heavy rain it will return to dock automatically. Light rain does not stop operation.
Can I use the Navimow on a garden with a pond or raised beds? Yes — you can define exclusion zones in the app around any obstacle. The mower will not enter mapped exclusion areas.
Does it work in winter? The mower should be stored indoors or under a weatherproof cover during extended winter periods. Most UK owners store between November and March.
What is the warranty on the H Series? Segway offers a two-year warranty on H Series mowers in the UK. The base station carries a one-year warranty.
How often do blades need replacing? Cutting blades are replaceable and typically last 2–3 months under normal UK usage. Replacement blade sets are available directly from Segway and third-party suppliers.
