Sunseeker Elite X9 / X9 Plus Robot Mower

The Sunseeker Elite X9 Series brings professional robotic mowing to large estates, sports grounds, parks and commercial landscapes. Available as the X9 for areas up to 12,000m² per 48 hours and the X9 Plus for up to 24,000m² per 48 hours, both models combine high-capacity mowing with all-wheel drive, intelligent navigation and automatic mapping.

With AONavi™ 2.0, 360° OmniSight™, infrared night vision and the powerful ATC Pro drive system, the X9 Series is designed to keep working accurately across large, complex and demanding sites without perimeter wires or a local RTK antenna station.

Built for Large-Scale Robotic Mowing

The Sunseeker X9 and X9 Plus sit at the top of the Sunseeker Elite range, offering significantly greater coverage and productivity than the residential X Series. Their wide dual-disc cutting system, fast operating speed and rapid charging make them particularly well suited to sites where large areas need to be maintained consistently with less manual mowing.

Where the Sunseeker X9 Series Excels

The X9 Series combines centimetre-level positioning with camera and sensor-based navigation. AONavi™ 2.0 uses nRTK and VSLAM 2.0 alongside the 360° OmniSight™ system to maintain accurate positioning around trees, hedges, narrow passages and other areas where satellite reception can become more challenging.

Automatic mapping can identify the mowing area and create a working map with minimal manual setup, while intelligent path planning calculates efficient mowing routes to reduce unnecessary overlap and repeated passes.

Professional All-Terrain Performance

ATC Pro combines all-wheel drive, four-wheel suspension and active rear-wheel steering to give the X9 Series stable traction across uneven and steep terrain. It can tackle slopes of up to 90% (42°), while wheel-cleaning brushes help maintain traction in muddy or debris-covered conditions.

The mower can also cross obstacles up to 5cm high, making it suitable for more demanding sites where changing ground conditions would challenge a conventional residential robot mower.

43cm Dual-Disc Cutting System

A 43cm dual-disc cutting system gives the X9 Series the width needed to cover large areas efficiently. Each floating cutting disc follows changes in the ground independently, helping maintain a consistent cut across uneven terrain.

Electronic cutting height adjustment from 20–100mm allows the mowing height to be controlled through the system, while Target Height Management can gradually reduce longer grass over multiple mowing cycles rather than attempting to remove too much growth in a single pass.

EdgeZero™ Edge Cutting

The EdgeZero™ system is designed to reduce the strip of uncut grass normally left beside suitable walls, fences and lawn boundaries. The attachment allows the mower to cut directly towards the edge at a right angle, reducing the amount of manual strimming required afterwards.

EdgeZero™ is optional on the X9 and supplied as standard with the X9 Plus.

Infrared Night Vision and 360° Obstacle Detection

Eight surrounding cameras and eight intelligent sensors provide the X9 Series with a 360° view of its working environment. Infrared-assisted detection extends this capability into low-light conditions, helping the mower recognise animals and other obstacles when operating at night.

This allows mowing schedules to extend beyond normal working hours — particularly useful for sports facilities, public spaces and commercial sites that are busy during the day.

Ideal Use Cases:

• Large private estates: Automate regular mowing across several acres without installing boundary wires.
• Sports grounds: Maintain large grass areas efficiently while scheduling mowing around training, matches and site use.
• Parks and public spaces: Manage extensive and multi-zone grass areas with automatic mapping and planned mowing routes.
• Commercial properties: Reduce repetitive mowing across campuses, hospitality venues and large business grounds.
• Professional landscapers: Fleet management allows multiple X9 Series mowers to be managed across larger operations.
• Golf courses: Suitable for rough and semi-rough areas where automated large-area mowing can reduce routine maintenance requirements.

X9 or X9 Plus?

Both models use the same core navigation, all-wheel-drive and cutting technology. The main difference is capacity and charging performance.

• Sunseeker X9: Covers up to 12,000m² per 48 hours and uses a 7A fast charger with an approximate 50-minute charge time. EdgeZero™ is available as an optional attachment.
• Sunseeker X9 Plus: Covers up to 24,000m² per 48 hours and upgrades to a 17A flash charger with an approximate 20-minute charge time. EdgeZero™ is included as standard.

Looking for Something Smaller?

The X9 Series is designed primarily for very large and professional mowing applications. For large residential gardens and smaller estates, the Sunseeker Elite X7 Series offers the same wire-free approach in a more compact package, with models designed for areas up to 6,000m².
