Robot mowers have been around for a long time, but for most of that time they worked the same way, by way of a buried perimeter wire around the edge of the lawn, allowing the mower to wander inside the boundary until the grass was short.It did the job, but it had a time-consuming setup, a wire that could be cut with a spade, and no real idea where it was.Newer wire-free mowers replace that cable with satellite positioning, cameras, and laser sensors.
Sunseeker Elite, the premium robotics brand from lawn care company Sunseeker, is one of the companies working in this space.It’s showing its current lineup at Equip Expo 2026 at the Kentucky Exposition Center in Louisville, Kentucky, from October 20 to 23.The main focus is the X8 Plus, a model for larger residential lawns that Sunseeker Elite is previewing at the show.
From garden tools to robots Sunseeker was founded in 2009 and spent its early years making garden products.It opened its first robotic mower R&D center in 2017 and launched its first robot mowers in 2019.Sunseeker Elite is now the company’s premium robotic brand, and its mowers are now sold in 74 countries.
That shift from traditional outdoor equipment to robotics is the theme of the company’s Equip Expo booth, which includes a timeline running from its early garden tools to its current mowers.Why going wire-free is harder than it sounds Sunseeker Elite X8 Plus Dimensions 29.8 × 24.2 × 16.9 in Obstacle Avoidance Solid-State LiDAR, Vision AI, Bumper, and Infrared Camera Slope Range 80%/39 degrees Brand Sunseeker Elite If your yard is large, sloped, or has lots of obstacles, you'll need a robot lawn mower that's up to the task.Sunseeker Elite has built the X8 Plus to navigate any yard, with nRTK positioning, solid-state LiDAR, and stereo vision from a binocular camera — what the brand calls AONavi 3.0.
This robotic mower has day and night vision, an infrared camera, EdgeZero 2.0 trimming tool, and more, so your lawn looks its best with little effort from you.Learn more at Sunseeker Elite Expand Collapse Without a boundary wire, a mower needs another way to know where the lawn ends and where it is at any given moment.Standard GPS isn’t precise enough on its own.
A typical satellite fix can be off by a few meters, which is the difference between mowing the grass and mowing the flower bed.The common solution is RTK (real-time kinematic) positioning.RTK uses correction data to sharpen a satellite fix down to centimeter-level accuracy.
Many RTK mowers rely on a separate base station antenna installed somewhere in the yard to supply those corrections.Network RTK (nRTK), which the X8 Plus uses, gets correction data over a cellular connection instead, so there’s no extra antenna to mount and power.Satellite positioning still has weak spots.
Tall trees, the side of a house, or a covered walkway can block or bounce signals, and a mower that relies only on RTK can lose track of its location.That’s the problem the rest of the X8 Plus’ sensors solve.How the X8 Plus sees the yard The X8 Plus has a core sensor package: nRTK positioning, solid-state LiDAR, and stereo vision from a binocular camera.
Sunseeker Elite combines these under a system it calls AONavi 3.0, which fuses all three inputs for positioning, navigation, and obstacle detection.LiDAR works by sending out laser pulses and timing how long they take to bounce back, which lets the mower build a 3D picture of its surroundings.Solid-state LiDAR does this without the spinning assembly found on many older sensors, so there are fewer moving parts.
Paired with the camera, it gives the mower a second way to understand its position when satellite reception drops.It also handles obstacle avoidance alongside Sunseeker Elite’s Vision AI, with a physical bumper as a final backup.The X8 Plus supports both day and night vision.
It also has an infrared camera as standard, which Sunseeker Elite uses for animal detection at night.If you schedule mowing after dark, that’s the part of the system meant to spot wildlife the regular camera might miss.Setup is handled in the app.
The mower builds a 3D textured map of the lawn, and you can edit boundaries over Google Maps imagery or drive the mower around the edge yourself using ride-on boundary cutting.Maps can be shared with other users, and the mower has an LCD on the body for quick checks.Edges, slopes, and rough ground Edges are a common weak spot for robot mowers.
Because the blades sit inside the body, they usually leave a strip of uncut grass along walls, fences, and paths, and you end up finishing the job with a string trimmer.The X8 Plus uses Sunseeker Elite’s EdgeZero 2.0 trimming tool, which is designed for a zero-inch edge gap and has five height levels.For uneven ground, Sunseeker Elite’s ATC Pro system combines all-wheel drive, rear wheel steering, and four-wheel suspension.
The X8 Plus is rated for slopes up to 80% (39 degrees), and Sunseeker says the system is built for traction and stability over potholes and rough ground as well as inclines.The cutting hardware includes a dual-disc deck that offers a 15.4-inch cutting width, and the floating discs follow the contours of the ground.Cutting height is electronically adjusted between 0.8 and 4 inches, and the maximum cutting speed is 1.3 mph.
There’s also an efficiency mode in the app.The mower is IPX6 water-resistant, has a built-in rain sensor, runs at a rated 60dB(A), and receives firmware updates over the air.It connects over Wi-Fi, Bluetooth, and 4G, and works with Alexa and Google Home.
Why the X8 Plus is a standout model The X8 Plus is a feature-packed mower designed especially for larger lawns; it covers up to two acres, with a larger 15Ah battery and a fast 7A charger.The mower also has an infrared camera and animal protection as standard, which is ideal if you plan to mow at night.This model also includes a 4G module.
Along with providing the connection for nRTK corrections, it powers anti-theft tracking, which is a real consideration for a mower that sits outside unattended.The X8 Plus includes five years of 4G service.The rest of the Sunseeker Elite lineup The X8 Plus sits within a wider range of wire-free mowers, all of which are on display at Equip Expo.
The X5 Gen 2, X7 Gen 2 and X7 Plus Gen 2 use Sunseeker Elite’s AONavi 2.0, which combines network RTK for centimeter-level positioning with VSLAM 2.0 visual mapping from a binocular and iToF camera system that helps them keep track of their position where satellite reception is patchy and detect obstacles in daylight and after dark.The X5 Gen 2 is designed for lawns up to half an acre.The X7 Gen 2 covers 0.75 acres, and the X7 Plus Gen 2 covers 1.5 acres, and both add all-wheel drive and floating dual cutting discs for larger, bumpier yards.
The X4 takes a different approach.It relies on 360-degree 3D LiDAR and Vision AI for positioning and mapping rather than satellite signals to cover 0.3 acres.At the other end of the range, the X9 and X9 Plus are built for large properties; the X9 covers 3 acres and the X9 Plus covers 6 acres, respectively.
What’s on display at Equip Expo 2026 Sunseeker Elite’s booth includes a technology area that shows live camera imagery from the mower’s point of view, along with explanations of how the machines handle navigation and path planning.It’s a useful way to see what the sensors actually pick up and how that turns into the route the mower takes.Outside, the brand will run slope demonstrations so visitors can see how the mowers handle inclines and changing terrain.
The company’s partnership with a well-known baseball team adds a themed robotic demo area and an outdoor pitching activity with prizes.Is a sensor-heavy mower worth it for your yard? The extra sensors on a mower like the X8 Plus earn their place on lawns with trees, slopes, tight borders, or areas where satellite reception is unreliable.Those are the yards where wired and RTK-only mowers tend to struggle.
If your lawn is flat, open, and has a clear view of the sky, a simpler model may cover what you need.For larger and more complicated properties, the X8 Plus combines nRTK, Solid-State LiDAR, and stereo vision with all-wheel drive, rear-wheel steering, and zero-inch edge trimming.That combination is aimed at cutting down the time you spend maintaining the lawn yourself, from setup through to the edges.
