Segway Navimow X390— Up to 2.5 Acres (Wire-Free GPS)

Perfect for Lawns Up to a 2.5 Acres

Segway Navimow X390 — Premium Long-Range Robotic Mower

High-Capacity Wire-Free Robotic Mowing for Lawns Up to 2.5 Acres

The Segway Navimow X390 is the highest-capacity model in the X3 Series, designed for large residential properties up to 2.5 acres.

It combines Segway's EFLS 3.0 positioning technology, vision-assisted navigation, systematic mowing and a larger battery system to maintain substantially more lawn without requiring a traditional buried perimeter wire.

For homeowners with genuinely large properties, the X390 provides a significant step up in capacity from the X330 and X350.

Built for Large Residential Properties

The X390's reason for existing is simple: capacity.

Within the RoboMaintain Navimow lineup:

X330 → up to 1 acre
X350 → up to 1.5 acres
X390 → up to 2.5 acres

That makes the X390 particularly compelling for properties that exceed the practical range of smaller residential robotic mowers but don't require an AWD system primarily for difficult terrain. Segway currently lists the X390 with a 12.8Ah replacement battery versus 8Ah for the X330 and 10Ah for the X350, reinforcing its position as the high-capacity X3 model.

For steep or traction-intensive properties, the X430 or X450 AWD may be the better direction even when the total acreage is smaller.

Property size is only part of selecting a robotic mower. Tree canopy, satellite visibility, slopes, narrow passages, separate mowing areas and overall property layout can affect system performance.
