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.

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.

Mowing is No Longer a Dreaded Chore

I have about 1/3 acre lawn and live in the Sunshine State. I love Florida, but in the middle of summer, mowing the lawn and cleanup takes about 90 minutes. I was always trying to plan my next mow around the kids schedule, the weather and any travel plans. Now that I have the mower setup, the only thing I need to do is trim the edges for about 15 minutes once a week. There are no lawn clippings on my yard anymore. This mower has been an absolute game changer for me. I will now sell my riding mower, and can ditch the gas can (except when needed for the generator). Overall, I am super stoked. One thing I would like to see in the future, is a camera on the machine. Perhaps they make them on other more expensive machines. I would like to see if there are any obstacles in the yard, or if any person or animal is near the unit. My other recommendation is for the machine to work on the edges a little better, near fences dn sidewalks. But still not a dealbreaker for me.

Love it!

Set up was a little pain but you have to go through the motions and set up step by step. Main thing is downloading the updates accordingly so the RTK antenna can communicate. Once it set up and running it cuts super great love it!

Surprisingly easy to set up, excellent results

I was surprised how easy it was to setup the Sunseeker X5. Using the app on my phone, I steered the robot around the perimeter of the lawn, around the "no-go" areas, and connected the strip of grass next to the road using a "corridor". I have scheduled cutting every other day, and I water deeply on no-mow days and now I can forget about the lawn, yest I have a professional finish.

I really love this little guy!

The installation process was easier than I expected. The initial setup took a little over an hour. After using it, the lawn height is very even, and daily maintenance hardly requires any effort from me.

Clean Results with Minimal Manual Touch-Ups

Edge cutting is better than I expected for a robot mower. While occasional touch-ups are needed, overall results are clean and tidy.

Premium Convenience Worth the Investment

The price reflects the technology, but the convenience of wireless setup, smart navigation, and automation makes it worthwhile.

Great yard work!

Great job! I’m sure I’ll need a discount code for my neighbors! More to follow.

If your half-acre has hills, get this

AWD grip, cm accuracy, tidy edges, virtual boundaries around the garden. For a sloped half-acre I stopped comparing and bought it. No regrets.

T
Tate E.
Cuts clean down the whole driveway

The offset blade trims right along our long driveway and the fence, edges I used to do by hand every week. That chore is simply gone now.

C
Chantal V.
Sold the zero-turn, kept my Saturdays

Spent every Saturday on a zero-turn for our sloped half-acre. The X5 climbs the same banks with AWD and cuts straighter lines than I did.

Q
Quinn G.
Top of the line, and priced like it

It's clearly the flagship — AWD, centimeter precision, the offset edge blade. The price is real, but for a sloped half-acre it's earned its keep already.

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

Brooke E.
Cheaper than the crew by fall

We paid a landscaper every two weeks for the half-acre. The X5 does it all itself, more consistently. On track to pay for itself this season.

Saw it at the store, ordered it that night

Checked out the build in person and was sold. The centimeter RTK precision is real — dead-straight stripes across the whole half-acre.

S
Sana Y.
Handles the spots my old one skipped

My previous robot dodged the slope and the tight corner by the shed. The X5 does the lot — climbs, edges, and maps the whole property without gaps.

Climbs the bank my old mower slid down

Our back slope is genuinely steep and 2WD stuff slid on it. The X5's all-wheel drive grips and climbs, no drama. Whole yard cut evenly now.

Della V.
Superb once mapped, big-yard map takes time

Walking and refining half an acre of map took a while. After that it's perfect. The AWD and precision on the grades are as advertised.

Della, we appreciate the feedback. You can fine-tune the edge trimming in the latest app update — reach out to support and we'll walk you through it. — SUNSEEKER Tech

Stripes my half-acre like a ballfield

The all-wheel drive gets the attention, but the cm-level accuracy is what wows me — no skipped rows, no overlap. The lawn looks professionally striped.

C
Colton W.
No more skipping the tough spots

My old robot just avoided the hill and the tight corner by the shed. The X5 does all of it — climbs, edges, and maps the whole property.

Delaney P.
Handles a 30-degree bank without drama

My side hill was a nightmare to mow by hand. The X5 grips it with AWD and cuts a clean line across. Best purchase for a hilly property.

G
Grady H.
Replaced a lawn crew

We paid for mowing every two weeks. The X5 covers our half-acre with slopes on its own, more consistently than the crew did. Paid for itself already.

S
Salvador E.
The straight lines are oddly satisfying

Centimeter precision means no missed strips and no double-cutting. The lawn looks striped like a ballpark. On a half-acre that consistency is impressive.

M
Marisol R.
Top model, and it feels like it

It's the top model and it feels like it — AWD, tight precision, edge blade. Only knock is it's a real investment. For a big sloped yard, worth it.

Thanks Marisol — appreciate you flagging the app onboarding. A firmware update coming soon addresses exactly that. — SUNSEEKER Tech

Priya T.
Our back slope finally gets mowed

We have a real grade that stalled every 2WD robot. The X5's all-wheel drive climbs it without slipping. First time the whole half-acre gets cut evenly.

E
Ebony V.
The AWD is not a gimmick

I was skeptical of the all-wheel-drive marketing until it powered up my back grade the first day. It genuinely climbs where my old robot spun out.

L
Leila S.
Superb once mapped, mapping a big yard takes time

The initial map of half an acre took a while to walk and refine. After that it's flawless. The AWD and precision are the real deal on grades.

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

Precise around every bed and tree

Set virtual boundaries around the garden and the trees and it respects them to the centimeter. No trenching, no wire. Half-acre handled cleanly.

The mower I'd recommend for hilly half-acres

If your yard has slopes and you're around 0.5 acre, this is it. AWD grip, cm accuracy, clean edges. Ours has never looked better.

C
Camila W.
AWD chews through my hilly half-acre

We've got a real slope in the back that stalled every 2WD robot I tried. The X5's all-wheel drive climbs it like it's flat. Finally the whole lawn gets mowed.

Malik S.
Half-acre with slopes, finally handled

0.5 acre with grades that beat my old mower. The X5's all-wheel drive and virtual boundaries mapped and mowed the whole thing. Precision is impressive.
