Sunseeker X5 Gen 2 Robotic Lawn Mower — 0.5 Acre
Free shipping to the contiguous U.S.
Description
The X5 Gen 2 brings Sunseeker's second-generation navigation to a half-acre lawn: network RTK fused with VSLAM 2.0, and a binocular-plus-iToF camera pair that lets it work at night as confidently as at noon. No boundary wire and no antenna to install: positioning runs over the built-in 4G module.
Cutting height is set by hand at the mower, so it suits a lawn kept on a regular schedule. If you change height with the season or take down tall growth, the X7 Gen 2 moves height from the app.
Shipping and Delivery
Delivery: Free within the 48 contiguous states. We do not ship this mower to Alaska or Hawaii.
Key Features
Navigation: AONavi 2.0 fuses network RTK with VSLAM 2.0 on a 10 TOPS chip. Where trees or buildings block RTK, the cameras keep it mapping and cutting.
Day and night: Vision AI 2.0 pairs a binocular camera for daylight with an iToF camera for dark, backed by a physical bumper for obstacles.
Anti-theft: The 4G GPS module is standard, with real-time tracking, adjustable geofencing, and boundary alerts.
Cutting: An 8.7-inch floating disc carries six blades at 2,300 RPM, with height set by hand from 1.6 to 3.2 inches. Ride-on boundary cutting, multi-angle patterns, and spot mowing are built in.
Edges: A trimming micro-blade deck cuts as close as 1.2 inches to edges.
Terrain: Tri-wheel all-wheel drive with a steering rear wheel, front independent suspension, and 8.7-inch off-road front wheels holds a 60% (30°) slope.
Zones: Draw virtual boundaries in the app, with no limit on zones.
Connected: Wi-Fi, Bluetooth, and 4G control, with rain detection, automatic recharging, night mode, an LED headlight, over-the-air updates, and Alexa or Google Home.

Installation and Compatibility
Network RTK service: Two years of NetRTK, 4G, and anti-theft service come with the mower. After that, renewal is $49 a year, and continued use requires an active subscription.
Site check: Network RTK needs cell coverage at the lawn and a view of the sky, so tell us about weak signal or heavy tree cover before you order.
Accessory: The Sunseeker Garage for X7 / X5 pairs with this mower as a weather cover for the mower and its charging station.
Warranty
Term: Two years on the mower and one year on the battery pack, from the date of purchase, for defects in materials or workmanship under normal, ordinary conditions. No registration is required.
Not covered: Normal wear on parts such as blades and tires, improper maintenance, accidental damage, accessories supplied with the mower, high-pressure washer damage, unauthorized repairs or parts, and storing the mower or battery outdoors below 32°F.
Claims: Contact us first, with your order number and the mower's serial number. We file the claim with Sunseeker and arrange the repair. A mower is replaced only if it is dead on arrival or cannot be repaired, and a replacement may not be new.
Frequently Asked Questions
Can it mow separate areas?
Yes, as long as it can get between them. It passes through gaps down to 28 in.
What happens when it starts to rain?
Rain detection sends it back to the charging station, and you can set a rain delay in the app before it resumes.
Can I hose it down?
Yes. It's rated IPX5, but stay away from pressure washers, because the warranty excludes that damage.

Half an acre, day or night
The X5 Gen 2 brings second-generation navigation to a half-acre lawn: RTK fused with VSLAM 2.0, and a binocular-plus-iToF camera pair that sees after dark as well as at noon. Positioning runs over network RTK on the built-in 4G module, with the cameras as backup.
The range
Six mowers, one ladder
Every model maps the lawn without a boundary wire. Moving up the ladder buys acreage, drive, and cutting hardware — pick by the yard, not by the badge.

The platform
Mapped, not fenced
The boundary lives in the app
No perimeter wire to trench, snag, or repair. Boundaries, no-go islands, and zones are drawn on the phone and redrawn in minutes when the yard changes — with no limit on how many zones you keep.
Network or LiDAR
The X5, X7 and X9 models run network RTK over built-in 4G, so there is no antenna to install. Service is included for at least two years on Gen 2 and five on the X9 pair. The X4 skips satellites entirely and navigates by LiDAR.
It does not stop at dusk
On the X5, X7 and X9 models a binocular camera handles daylight and iToF takes over at night, so the mowing window is the whole day. The X4 pairs its LiDAR with one camera and a night mode. Working noise stays at 60 dB(A) across the X4 through X7 Plus — quiet enough to run while the house sleeps.
Before you order
Plain talk, as usual
Acreage is a rating, not a promise
Coverage figures are measured on sane schedules and reasonable ground. Complex layouts, heavy growth, and long narrow passages all eat into them. If your lawn sits near the line between two models, take the larger one.
Two ways of knowing where it is
This range does not navigate one way. The X4 reads the yard with LiDAR and needs no sky at all. The X5, X7 and X9 models use network RTK with vision backup, which leans on cell coverage and a reasonable view up. Tell us about tree canopy or a weak signal and we will point you at the right one.
Height adjustment splits the range
The X4 and X5 Gen 2 set cutting height by hand at the machine. From the X7 Gen 2 up it moves electronically from the app, including target-height cutting over several passes. If you change height with the season, that line in the table is worth more than the acreage.
Plain answers
What do I install before it can mow?
Only the charging station, which needs household power. The X5 Gen 2 needs no antenna or base station, because it runs network RTK over its built-in 4G module.
Where should the charging station go?
In the open, within reach of household power. The mower needs to see satellites when it docks, so keep the station away from the house or other buildings that block the sky.
Will it work with trees over the lawn?
Yes, within limits. Where trees block RTK, the cameras keep it mapping and cutting, but work without a position fix is limited in time and distance and can lose accuracy. If dense canopy covers most of the yard, look at the X4, which navigates by LiDAR and needs no view of the sky.
Is 4G included?
Yes. The 4G module is standard, with two years of NetRTK and anti-theft service included. Renewal is $49 a year, and continued use requires an active subscription.
My grass has grown long. Can it cut it?
Start on a lawn that has been cut recently. Height is set by hand at the mower, from 1.6 to 3.2 in., so if the grass is well above that, give it one pass with a conventional mower first. The X5 Gen 2 suits a lawn kept on a regular schedule.
What do I do with it in winter?
Bring the mower and its battery indoors before temperatures fall below 32°F. Storing either outdoors below that is not covered by the warranty.
Can I return it if it does not suit my lawn?
Only if it is new and unused, within 30 days of delivery, or defective on arrival. A mower that has been set up and run counts as used, and approved non-defective returns carry a 25% restocking fee. Tell us about tree cover first and we will point you at the right model.
