At a high level, the Luba 2 AWD 3000X and Luba 2 AWD 5000HX share the same core identity: both are electric, app-connected robotic mowers with identical connectivity (Wi-Fi, Bluetooth, and remote smartphone control), the same 40 cm cutting width, and the same noise profile of 60 dB standard and 50 dB in eco mode. Their weight (18,597 g) and footprint width and thickness are also identical, meaning handling and storage requirements are the same for both units.
The defining differentiator is coverage capacity. The 5000HX is built for significantly larger properties, with a recommended area of 5,059 m² versus 3,035 m² for the 3000X — a roughly 67% increase. Maximum lawn area coverage follows the same pattern: 6,070 m² versus 3,642 m². This difference is likely enabled by a larger body — the 5000HX stands 302 mm tall compared to 272 mm for the 3000X, contributing to a noticeably larger overall volume (106,589 cm³ vs 96,001 cm³), which likely accommodates a bigger battery or more capable internals.
The choice between these two comes down entirely to lawn size. For gardens under roughly 3,000 m², the 3000X is the right-sized tool with no functional penalty. For anything approaching or exceeding 5,000 m², the 5000HX has a clear and decisive edge — its larger coverage capacity means fewer missed areas and fewer recharge-and-resume cycles. If your property sits in the middle range (3,000–5,000 m²), the 5000HX provides meaningful headroom and is the safer long-term choice.
