Mammotion Yuka mini 800H VS Segway Navimow i108

Both the Mammotion Yuka mini 800H and the Segway Navimow i108 share an identical connectivity foundation — Wi-Fi, Bluetooth, a dedicated smartphone app, and remote smartphone support — so neither has an edge in how you interact with or control the mower. Their cutting widths are also identical at 21 cm, meaning productivity per pass is a wash. Where these two robotic mowers start to diverge is in coverage capacity and acoustic behavior.

The Yuka mini 800H holds a meaningful advantage in lawn coverage, with a recommended area of 809 m² versus the Navimow i108's 640 m² — roughly 26% more. Its maximum lawn area coverage follows the same pattern at 971 m² versus 800 m². For anyone with a mid-to-large garden, this difference is practically significant: the Navimow i108 may struggle to keep up on larger plots without compromising mowing frequency. On the noise front, the situation reverses: in standard operation, the Navimow i108 runs at 54 dB compared to the Yuka's 60 dB — a 6 dB gap that, on the logarithmic decibel scale, translates to the Navimow sounding roughly half as loud to the human ear. In eco mode, both models converge at 50 dB, eliminating that advantage.

In terms of physical form, the two are broadly comparable. The Navimow i108 is slightly narrower (385 mm vs. 414 mm) while the Yuka is modestly lighter (10,433 g vs. 10,900 g), though neither difference is large enough to meaningfully affect handling or storage. Overall, the Yuka mini 800H holds the stronger general-use edge for buyers with larger lawns, while the Navimow i108 is the better pick for noise-sensitive environments — particularly if the garden is under 640 m².

Across every feature tracked in this group, the Mammotion Yuka mini 800H and the Segway Navimow i108 are in complete lockstep. Both carry the full suite of smart autonomy features: obstacle sensing, rain sensing, frost sensing, and automatic docking — a combination that means either mower can independently adapt to changing conditions without user intervention, protecting both the lawn and the machine itself.

The environmental intelligence features deserve particular attention. The presence of weather adaptation and a frost sensor on both models means they can avoid mowing on frozen or waterlogged ground — situations where mowing would damage grass roots. The fact that both also work in rain adds operational flexibility, allowing them to continue on schedule through light precipitation rather than retreating to the dock at the first drop. Add in mulching capability on both units, and neither buyer needs a separate grass collection or disposal strategy — clippings are returned to the lawn as natural fertilizer.

Voice assistant compatibility with both Alexa and Google Assistant, combined with on-device displays and scheduling, rounds out an identical smart-home integration picture. There is simply no differentiator to call out here: this group is a complete tie. Buyers should weight other spec groups — such as coverage area or hardware specifications — when choosing between these two models, as features alone will not break the deadlock.

The most striking divergence in this group is working area capacity. The Mammotion Yuka mini 800H covers 162 m²/h compared to the Segway Navimow i108's 62.5 m²/h — meaning the Yuka works through terrain roughly 2.6 times faster. This directly reinforces the larger recommended coverage area established in the general specs: the Yuka is not just rated for bigger lawns, it is mechanically geared to handle them efficiently. The Navimow i108, by contrast, compensates with a much longer single-session mowing time of 180 minutes versus the Yuka's 55 minutes, suggesting it runs at a more measured pace and relies on extended, uninterrupted operation rather than raw speed.

Slope handling gives the Yuka another narrow but real advantage — 50% gradient tolerance versus 45% for the Navimow. On flat or gently rolling lawns this is inconsequential, but for gardens with steep embankments or terraced sections, that 5-percentage-point gap could determine whether a mower can safely operate on a given section at all. Meanwhile, the cutting height ranges tell two different lawn-care stories: the Yuka spans 51–89 mm, favouring lusher, longer grass styles, while the Navimow reaches down to 30 mm with a ceiling of 60 mm, making it better suited to fine, manicured lawns that require close, precise cuts.

On balance, the Yuka mini 800H holds a clear performance edge for most users — its speed advantage and slope capability are substantial. However, the Navimow i108 is the stronger choice for owners of fine-turf lawns where low cutting heights matter, and its long mowing sessions may suit setups where frequent docking is inconvenient.

Both mowers share the practical advantage of a removable battery, which matters more than it might initially seem — it means users can charge a spare battery indoors while the mower is deployed, or simply swap packs rather than waiting for a full charge cycle. That convenience, however, plays out very differently for each model when you look at actual charge times: the Mammotion Yuka mini 800H replenishes in just 1.5 hours, while the Segway Navimow i108 requires 3 hours — exactly double. For a mower that also has a shorter working session (as established in the performance group), faster recharging is a meaningful operational benefit, keeping downtime to a minimum.

The electrical specifications present a striking contrast. The Yuka operates at 36.7V and 88W, while the Navimow draws a substantially higher 367W at a lower 11V. The Navimow's wattage figure is more than four times greater, which translates directly into higher energy consumption per hour of operation — relevant to running costs and grid load, particularly for users in regions with high electricity prices or those mindful of energy efficiency. The Yuka's lower wattage profile also aligns with its shorter mowing sessions, suggesting a system optimized for frequent, efficient charge-and-go cycles rather than sustained high-draw operation.

On power, the Yuka mini 800H holds a clear advantage for most buyers: its charge time is half that of the Navimow, and its significantly lower wattage points to more economical energy consumption. The Navimow's high draw may be a trade-off for its longer continuous mowing sessions, but users prioritizing turnaround speed and running costs will find the Yuka the more practical proposition here.
