Description

The Sunseeker X3 Plus is a wire-free robotic lawn mower for smaller lawns up to 0.3 acre (about 13,000 sq ft). AONavi combines RTK-GNSS satellite positioning (RTK base station included) with VSLAM visual navigation for centimeter-level accuracy, and Vision AI with binocular cameras detects and avoids more than 200 types of obstacles, both static ones like trees and fences and moving ones like pets and people.

A floating cutting disc follows the contour of your lawn for an even cut, and the X3 Plus handles slopes up to 17° (30%).

Key Features

Wire-free mapping: AONavi (RTK + VSLAM) with editable maps and virtual fences.
Vision AI obstacle avoidance: binocular cameras recognize 200+ obstacle types.
Floating cut: the cutting disc adjusts to uneven ground.
Multi-zone: multiple working zones and no-go zones in the app.
Auto recharge: returns to the charging station when the battery is low.

From the app you can set working zones, no-go zones and schedules, and the mower returns to charge on its own when the battery runs low.

FAQ

Do I need to lay a boundary wire?

No. You map the lawn in the Sunseeker app and set virtual boundaries, zones and no-go areas there.

Is the RTK base station included?

Yes. The X3 Plus comes with the RTK base station, its holder and charger.

How steep a slope can it handle?

Up to 17° (30%).

Should I choose the X3 Plus or the X4?

Both cover about 0.3 acre. The X3 Plus uses RTK with an included base station. The X4 uses 3D LiDAR, so there is no base station, and it handles steeper 45% (24°) slopes.
