Meet the Sunseeker Elite X9 Plus

​ Commercial-Grade Robotic Mowing for Big Properties

If you manage a school campus, athletic complex, municipal park, or any property where mowing eats up hours of labor every week, the new Sunseeker Elite X9 Plus deserves a serious look. It made its debut at CES 2026 and is now arriving in the U.S. commercial market — and it's built specifically for the kind of large, demanding properties most robot mowers can't handle.
Here's what sets it apart.

Built for 6 Acres, Not 6,000 Square Feet

​Most robotic mowers on the market are residential machines dressed up in commercial marketing. The X9 Plus is different. It covers up to 6 acres, and with Sunseeker's fleet management platform, multiple units can work together across even larger sites — coordinating routes, balancing workloads, and reporting maintenance data back to your team. For a school district or grounds department, that means one dashboard managing your entire mowing operation.

It Actually Sees Where It's Going

The X9 Plus runs a 16-sensor perception system called OmniSight, including 8 cameras with full 360-degree awareness. It recognizes obstacles, terrain changes, and even wildlife in real time. Infrared detection lets it operate safely at night and in low light, spotting small animals in the grass before they become a problem. That's a big deal for parks and campuses where kids, pets, and equipment share the turf.
​
Navigation combines RTK satellite positioning with visual mapping (VSLAM 2.0) for centimeter-level accuracy — no boundary wires to bury, no wires to break, no re-trenching when your layout changes.

Slopes That Would Stop a Zero-Turn

Here's the number that gets attention: the X9 Plus climbs grades up to 42 degrees — that's a 90% slope. Four-wheel drive, independent suspension, and rear-wheel steering keep it stable and cutting in straight lines on hills, ditches, retention pond banks, and the rough terrain that usually requires a crew member with a string trimmer and a prayer.
The independent suspension also keeps the cutting deck level on uneven ground, so you get a consistent cut height across dips and bumps instead of scalped patches.

No More Missed Edges

Sunseeker's EdgeZero trimming attachment comes standard on the X9 Plus. It extends out to cut at zero distance along fences, walls, curbs, and building foundations — the spots every mower misses and every crew has to come back and trim by hand. It has its own dedicated camera to stay aligned and tucks itself in automatically when it detects an obstacle.
If you've priced out the labor cost of edge trimming across a large property, you know this feature alone changes the math.

​20-Minute Charging Keeps It Working

Downtime kills productivity. The X9 Plus uses Sunseeker's high-power flash charging to go from empty to full in about 20 minutes, then gets right back to work. Combined with its 42V, 8Ah battery and a top mowing speed of 3.3 feet per second, it's designed to knock out 6 acres within a 48-hour mowing window.

Who Should Be Looking at This

The X9 Plus is aimed squarely at property managers, school districts, municipalities, sports facilities, and commercial landscapers. It's also suited for the rough and semi-rough areas of golf courses. If your grounds crew is stretched thin or you're paying overtime just to keep up with growing season, autonomous mowing is one of the fastest ways to reclaim labor hours without sacrificing turf quality.
