Sunseeker X3 Plus Wireless AI Robot Lawn Mower | 0.3 Acre
Overview
Overview
Precision Edges. Zero Wires. Total Control.
The Sunseeker X3 Plus is engineered for the suburban homeowner who demands perfection. Traditional robotic mowers often leave a messy strip of grass along fences and walls, forcing you to finish the job manually. The X3 Plus solves this with our proprietary Ride-on-Edge technology, gliding along boundaries for a beautifully manicured finish. Navigating complex yards up to 0.5 acres is seamless, thanks to the robust AONavi™ Fusion system that blends RTK GPS and visual tracking. Create virtual boundaries, set up multi-zone schedules, and enjoy a consistently perfect lawn without the weekend labor.

Stays Accurate When Real Life Happens
Open lawns are the easy part. Trees, narrow side sections, and changing light are what test navigation. The Sunseeker X3 Plus fuses RTK positioning with VSLAM vision to hold a stable path in typical home yards, then follows systematic parallel routes instead of moving randomly.
RTK + VSLAM fusion for precision guidance
Recognizes Objects Accurately Day and Night
Delivering efficient coverage with structured, predictable mowing performance.
True Edge Cutting
Less Time Trimming
Edge cutting is where most robot mowers leave a strip behind. The X3 Plus Ride-on-Edge design reaches over borders to cut closer along fences, beds, and hardscapes, so a 0.3-acre yard needs less follow-up trimming and fewer manual touch-ups.
Designed for Everyday Lawns
Built for the 3 things that make yards “hard.”
Dual AI Vision
No Rescue Needed. Detect & Avoid 360+ Obstacles
Sunseeker Vision AI recognizes 360+ common yard objects and plans routes around them, helping reduce uncut grass around trees, beds, and garden features.
Efficient Accuracy
Effortless mowing that adapts to your preferences, while being extra gentle on your lawn for a pristine and healthy landscape.
TOTAL CONTROL IN YOUR POCKET
Create separate zones for different lawn areas. Assign unique schedules, cutting patterns, and priorities to each zone.
