Segway Navimow X450 AWD Robot Lawn Mower – 5000m²

The Segway Navimow X450 AWD Robot Lawn Mower is the high-capacity X4 model for very large residential lawns and acreage up to 5,000 m². It pairs a powerful AWD chassis with a 430 mm dual-disc cutting system, wire-free Network RTK positioning and 360° AI vision so large, difficult lawns can be maintained with less hands-on mowing.

With a larger 15 Ah battery than the X430 and the same 40° slope capability, the X450 is aimed at owners who need more coverage without giving up precise mapping, obstacle awareness or turf-friendly manoeuvring.

Key Features

• Designed for mowing areas up to 5,000 m².
• Full-time Xero-Turn™ 4WD / AWD with dual suspension.

• VisionFence™ 360° RGB camera + ToF system with 200+ obstacle recognition.
• 430 mm dual-disc cutting system powered by twin 180 W motors.
• Automatic 20–95 mm cutting height.
• One-tap Auto Mapping, visual map editing, virtual boundaries and multi-zone management.
• 15 Ah battery with 100-minute Australian-listed charge time.

Navigation, Positioning & Wire-Free Mapping

The X450 is engineered around EFLS™ NRTK. Network RTK, 360° camera data and VIO work together to give the mower precise localisation without buried boundary wires. The X4 platform also uses tri-frequency RTK and supports one-tap Auto Mapping, allowing the mower to create a lawn map that can then be visually edited in the Navimow app.

Cutting System

Two 180 W cutting motors drive a wide 430 mm dual-disc cutting system, helping the X450 cover substantial lawn areas efficiently. Automatic cutting-height control spans 20 mm to 95 mm, giving owners flexibility to adjust the finish for changing turf conditions.

Terrain, AWD & Slope Capability

AWD traction, dual suspension and turf-conscious front-wheel steering are designed for challenging ground without relying on aggressive skid turns. The X450 is rated for slopes up to 84% (40°) and can cross obstacles up to 70 mm, giving it the hardware to cope with uneven lawns, roots and changing terrain.

Vision & Obstacle Avoidance

The panoramic VisionFence™ system combines 360° RGB cameras with ToF sensing. It can recognise more than 200 obstacle types and feeds that information into the mower’s navigation system, supporting safer, more deliberate movement around objects commonly found on large residential properties.

App, Auto Mapping & Multi-Zone Control

From the Navimow app you can manage virtual boundaries, Auto Mapping, zones, schedules and mower settings. Bluetooth, Wi-Fi and cellular connectivity support connected control, while OTA updates and weather-adaptive functions help keep the X450 operating as a modern smart outdoor appliance rather than a set-and-forget mechanical timer.

Battery & Automatic Charging

The X450 carries a 15 Ah battery with a 100-minute charge time on the Australian specification. Segway/Navimow manufacturer documentation rates full-charge mowing runtime at up to 130 minutes under its stated test conditions, with automatic return-to-charge functionality built into normal operation.

Why Choose the X450?

The X450 is the X4 choice for owners who want maximum residential coverage. It is particularly well suited to very large lawns where a smaller robot would spend too much time cycling, and where steep ground or uneven surfaces make AWD, suspension and visual navigation worthwhile upgrades.
