For Real Yards

Self-driving-level Navigation

Most mowers say “smart navigation.” What matters is whether it stays confident when your yard stops being a showroom.

Load video:

Conquer any Terrain

All-wheel drive delivers strong, efficient performance across slopes up to 60% (30°), for smooth and reliable operation on uneven ground.

Predictable, Systematic Paths

Cleaner coverage with fewer missed strips, so results look intentional—not random.

Made for Real Backyards

Designed for yards with trees, walls, and tight runs—where signal and visibility aren’t always perfect.

Built to hold its line when real life happens

What if trees block the satellite signal?
Tree canopy

What if trees block the satellite signal?

AONavi Pro fuses RTK satellite positioning with V-SLAM vision. When the sky view drops out under canopy, vision keeps the X5 on its line — so it stays accurate where wired and GPS-only mowers drift.

What happens if it gets stuck?
Stuck or off-track

What happens if it gets stuck?

Multi-sensor avoidance steers around obstacles, and if the X5 ever stalls it pauses and sends a push alert to the app with its exact location — no hunting across the yard.

Can I change boundaries later?
Complex multi-zone

Can I change boundaries later?

Create up to 100 zones, no-go areas and corridors in the app, and re-walk or edit any boundary anytime — nothing is dug into the lawn, so the map bends to your yard.

Backed long after the box is opened

2-Year worry-free warranty

Every X5 is covered for two full years. If something fails, our team arranges a repair or replacement — just reach out.

Spare parts when you need them

Blades, wheels and casters are stocked and orderable directly — no driving to a dealer to keep your mower running.

Real human support

U.S.-based help by email and our 7/12 hotline. Have a yard-fit or setup question? Talk to us before you buy.

30-Day returns

Try the X5 in your own yard. If it isn't the right fit within 30 days, send it back.

Up and mowing in about 20 minutes

You do not need strong signal across your yard. The X5 only needs Wi-Fi where the charging base sits — the RTK antenna and mower handle the rest, even on a 3-story lot.

1 Place the base & RTK antenna

Set the charging dock near a Wi-Fi point and mount the RTK antenna where it has a clear view of the sky. No trenching, no boundary wire.

2 Walk the perimeter in the app

Drive the X5 around your lawn once from your phone, then drop no-go zones and corridors. Most yards are mapped in 20–25 minutes.

3 Schedule and forget it

Set cutting days and heights (1.6–3.2 in), and the X5 docks, charges and resumes on its own. Edit zones anytime.

FAQ

What obstacles can the X5 detect and avoid?

The Sunseeker X5 robot lawn mower uses two layers of obstacle avoidance. AI avoidance recognizes the type of object ahead and steers around it; anti-collision avoidance physically detects objects taller than about 15 inches that the camera does not classify. In everyday use it works around common yard objects such as toys, garden hoses, flower pots, exposed tree roots, stumps, chairs, water pipes, pets, and people.

The X5 configured exactly right

AWD for the slopes, an offset blade the bundle keeps sharp, virtual boundaries for the garden, and a garage over the dock. Everything in place.

Whole package — level the pad and go

It all works together nicely; just level the garage spot for square parking. AWD, precision and the blade kit are each excellent.
