Self-driving-level Navigation

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

Conquer any Terrain

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

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.

Protecting a flagship just makes sense

Spent the money, so the garage was a no-brainer. Keeps sun and rain off the dock, and the AWD handles our grades. Clean all around.

Hector M.
Great combo, shim the pad if needed

Love the AWD precision and the weather cover. Mine needed a small shim to park perfectly square — worth doing for reliable docking.

Thanks Hector — appreciate you flagging the firmware update prompt. A firmware update coming soon addresses exactly that. — SUNSEEKER Tech

Nathaniel D.
Sheltered charging on a big lot

No debris on the dock, no weather on the electronics, and the AONavi precision covers the whole yard. The garage was money well spent.

Appreciate the kind words, Nathaniel. Stories like yours are exactly why we built it this way. — SUNSEEKER Tech

Leila H.
Cool in summer, dry in fall

The garage keeps the mower shaded in July and dry in October. Meanwhile it stripes our half-acre with cm precision. Complete package.

Y
Yusuf G.
Solid cover, a little assembly

The garage is sturdy but took some assembling. Worth it to shelter a mower this good. The X5's slope climbing is as advertised.

Thanks for the honest review, Yusuf — fair point on the app onboarding, and it's on our list to improve. Glad the rest is working for you. — SUNSEEKER Tech

Keeps the investment safe outdoors

The X5 lives outside year-round so the garage matters. It stays protected between mows and still climbs everything on our property.

AWD muscle with a dry home

The garage keeps the dock out of our afternoon storms and the X5 still climbs my back slope like it's flat. Best setup for a hilly half-acre.

S
Sana P.
Storm season is a non-issue now

Heavy rain used to worry me about the charging contacts. The garage solved it. The X5 still tackles the hill with all-wheel drive. Very happy.

Imani N.
Cheap insurance for an expensive mower

If you're buying the X5, add the garage. Dock stays clean and dry, mower stays sheltered, and it still climbs our sloped half-acre with ease.

Bradley A.
Hills handled, dock protected

AWD for the grades, virtual boundaries for the beds, and a garage keeping it all dry. Set it up once and it just runs, rain or shine.

Akira N.
Flagship performance, sheltered charging

AWD on the hills, offset edge blade, and now a garage keeping it all out of the weather. This is the X5 setup to get if you're outdoors in all seasons.

D
Derek E.
AWD power with a weatherproof home

The garage version keeps the dock dry through our storms and the X5 still climbs my slopes like nothing. Best of both worlds for a half-acre.

V
Vanessa B.
Solid protection, minor assembly

The garage took a bit to assemble but it's sturdy. The X5's slope climbing and precision are as good as everyone says. Four stars just for the setup time.

Great to hear it's performing, Vanessa. Noted on the schedule options — our team is actively working on that. Thanks for the four stars. — SUNSEEKER Tech

Spent flagship money so protecting it made sense. The garage shields the dock from sun and rain and the AWD handles my hilly yard. Clean setup all around.

Sun and rain handled

Full-sun yard and the garage keeps the plastics from fading and the dock dry. The X5's precision and hill-climbing are the real stars.

Dock stays clean and dry

No leaves or rain on the charging contacts anymore. Reliable charging every night and the AWD handles my half-acre slope all day.

Worth it to shelter a mower this good

If you're investing in the X5 flagship, the garage is cheap insurance. Dock stays clean, mower stays protected, and it still climbs everything on my property.

E
Estelle G.
Good add-on, snug fit

The garage does its job protecting the dock and mower. Fit is a little tight lining it up but that's minor. The X5 itself powers up my hill like a champ.

Thanks Estelle — fair point, and we appreciate the honest feedback. If you ever want a hand fine-tuning the app or setup, our team's a message away. — SUNSEEKER Tech

Destiny M.
Clean, covered, high-end

The garage keeps the flagship looking and running like new. Between the AWD and the weather cover this is the most premium lawn setup I've owned.

Savilla H.
Best call for a sunny lot

Full sun all day and I wasn't about to cook a two-grand mower. The garage solved it and the AWD owns my grade. Perfect pairing.

Junius C.
Keeps a pricey mower like new

A machine this capable deserves shelter. The garage keeps sun and rain off it and it still tackles my half-acre grade without a stumble.

Looks intentional, runs flawless

The garage looks purpose-built in the yard, and the mower under it never misses. Clean, deliberate setup.

U
Ursel B.
Sun and storms both handled

Full sun by day, storms by evening — the garage keeps the X5 protected through all of it.

M
Mabel P.
Great combo, wish garage were bigger

Really pleased. The X5 is a beast on my hill and the garage keeps it protected, though a touch more room would help. Support was helpful with a dock alignment question.

Thanks for the balanced take, Mabel. Glad the core is working for you — reach out to support and we'll sort the small stuff. — SUNSEEKER Tech

J
Jamal Q.
Great combo, position the garage carefully

Love the AWD precision and the dock cover. Just make sure you level the garage spot — mine needed a shim so the mower parks square every time.

Great to hear it's performing, Jamal. Noted on the edge trimming — our team is actively working on that. Thanks for the four stars. — SUNSEEKER Tech

Jocelyn H.
Storms don't bother it now

We get heavy afternoon rain and the garage keeps the charging contacts clean and dry. The X5 still tackles the back slope with all-wheel drive. Very happy.

S
Sofia L.
Weather cover was a must for me

Our dock sits in the open on the slope side of the yard. The garage means the X5 isn't baking or getting soaked between runs. Clean look, easy assembly.

H
Hobart A.
Great shelter, prep a level pad

The garage is excellent once you've got a flat, anchored spot. On my sloped yard that took some prep. The mower itself is flawless.

Appreciate it Hobart — a level, anchored pad is the trick with the garage, and support can share our placement tips and extra stakes. — SUNSEEKER Tech

D
Derek T.
Keeps sun off in summer, rain off in fall

The garage matters more than I expected — the mower stays cooler and the electronics stay dry. Meanwhile the AWD handles my sloped lawn effortlessly.

Garage keeps my flagship protected

Spent real money on the X5 so sheltering it made sense. The garage keeps sun off the shell and rain off the dock. After a month of afternoon storms it still charges perfectly.

Rain rolled in, mower stayed dry

Storm came through and the X5 was tucked away charging. The garage already earned its keep. Cuts my sloped lot beautifully otherwise.
