AI That Sees Your Yard — Fully Wireless, Even Under the Trees

The S4 is an AI robot lawn mower that maps and mows your yard entirely on its own — even under a dense tree canopy where GPS-based mowers lose signal. 3D LiDAR builds a precise map of your lawn while Vision AI reads the path ahead in real time. It's completely wireless — battery-powered with no power cord and no cables trailing across the grass; it runs by itself and returns to the dock to recharge. And because it actually sees what's ahead, it slows and steers around the hoses, toys, planters, and flower beds most yards are full of.

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:

LiDAR-led 3D Understanding

Builds a yard-level 3D map and plans routes based on real geometry—not guesswork.

Load video:

Predictable, Systematic Paths

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

Load video:

Made for Real Backyards

Designed for shaded yards with mature trees, walls, and narrow passages between obstacles, where GPS signal and camera visibility aren't always perfect.

Obstacle Avoidance

3D obstacle avoidance designed for daily life

Yard life changes every day, with kids' toys, hoses, furniture, and pets. The S4 robot lawn mower with LiDAR combines 3D LiDAR sensing and vision-based detection to avoid common obstacles and keep mowing.

Precision Cut

Cut Quality Matters

Sunseeker is a newer consumer brand, but the team behind S4 is backed by nearly 15 years of outdoor power equipment manufacturing experience—and that shows in the cut.

Lorraine L.
No support calls in six months

The S4 finished every run under our oaks, the shelter kept the dock dry, and my only job was two blade swaps from the kit.

K
Kenji T.
Shipping crack, fast replacement

The shelter lid showed a hairline crack when I unboxed it. Photo to support, new lid in seven days. The S4 never missed a run under the trees meanwhile.

Fair review, Kenji. that is a known gap and we're on it. Reach out to support if it gets in the way again. — SUNSEEKER Tech

R
Rhonda C.
Came for the mapping, stayed for the kit

I only cared about LiDAR under our oaks. Turns out the shelter and the blade stack are what I'd have ordered three months later anyway. Shelter directions could use pictures.

Thanks Rhonda — fair note on the blade swap. We're working on it and appreciate the honest four stars. — SUNSEEKER Tech

H
Harold S.
Canopy, rain, blades: covered

We have twelve mature trees on a quarter acre. The LiDAR map ignores the canopy, the shelter ignores the rain, and the spare blades ignore the acorns. I ignore the lawn now.

Appreciate the detail, Harold. the LiDAR under tree cover is the whole point of the S4. Enjoy the weekends back. — SUNSEEKER Tech

C
Cedric T.
Shade lot, full kit, no chores

LiDAR mower for the trees, garage for the weather, blades for the season. Set up one Saturday in May and touched twice since.

Appreciate the detail, Cedric. the LiDAR under tree cover is the whole point of the S4. Enjoy the weekends back. — SUNSEEKER Tech

J
Jamal B.
Mower is the star, extras are sensible

The S4 under our oaks is why you buy. The garage and blade pack saved two later orders. Garage assembly instructions assume experience.

Jamal, glad it's earning its keep. We hear you on the garage design; that's on our list. — SUNSEEKER Tech

R
Russell E.
Half a year, two swaps, no calls to support

Garage kept the dock dry, the S4 finished every run under our oaks, and the only maintenance was two blade swaps from the kit.

J
Joanne R.
Bigger than the product photo

The shelter took more patio corner than I planned and a planter had to move. Once placed, it looks tidy and the S4 handles the shade without issue.

J
Joanne F.
Two properties, two bundles

Bought one for home, liked it, bought one for my mother's quarter acre. Both under heavy shade, both flawless. Garages keep her dock clean without her bending down.

F
Fabian V.
Christmas lights season, dock stayed clear

We string lights along the patio in November. The garage kept the cords and clips off the charging plate. S4 kept mowing under the maples until frost.

Appreciate the detail, Fabian. glad the garage is keeping the dock dry. Enjoy the weekends back. — SUNSEEKER Tech

H
Hana T.
pnw drizzle, lidar doesn't care

portland. canopy everywhere. the s4 maps with lidar, the shelter keeps the dock out of the wet, and the spare blades got me through needle drop.

S
Sekou R.
Clean cut, dry dock, nothing buried

Deep shade and constant leaf litter used to defeat our mowers. This bundle handles both: a dry protected dock, sharp blades, and LiDAR that holds its line under the trees.

A
Amir I.
The version to get if it lives outside

Garage for the weather, spare blades for the cut, LiDAR for the trees. Our shady, rainy lot has met its match. Nothing to add.

B
Brooke W.
No accessory shopping later

I didn't want to be ordering a cover and blades separately in a month. Got them together — the S4 maps under the canopy, mows clean, and parks protected. One and done.

Y
Yusuf B.
Genuinely don't think about it anymore

Weeks in and I've basically forgotten it exists — it mows the tree-covered yard, dodges the beds, docks under its cover, repeats. The whole point of buying the loaded version.

V
Viktor F.
Kitted out and worth it under the canopy

Weather cover, spare blades, wire-free LiDAR — the shaded quarter-acre looks manicured and I do nothing but empty the bin. If you're buying the S4, get this one.

Q
Quan V.
Sorted in one order, sharp all season

Bundling the garage and blades saved a second shopping trip. First-boot firmware took ten minutes, then it's been flawless mowing the shaded lot and tucking itself away dry.

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

B
Bradley J.
One box, fully sorted in an afternoon

Didn't want to chase accessories later, so the garage-and-blade combo was the move. Protected dock, sharp cut, no wire from day one.

O
Oscar S.
The all-in S4 for a wet, shady lot

Rains most weeks and we're surrounded by maples. The garage keeps the dock dry, the blade kit keeps the cut sharp, and the LiDAR never drifts. Set it and left it.

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

N
Natalie C.
The whole thing in one go

Mower, shelter, spares. S4 LiDAR navigation under our trees is the best I've used. Garage keeps it looking neat by the patio.

Natalie, this made our week. the LiDAR under tree cover is the whole point of the S4. — SUNSEEKER Tech

M
Mei P.
Covered, sharp, and never lost under trees

Three things I wanted: weather protection, a crisp cut, and no drift in the shade. The garage-and-blade S4 nails all three on our quarter-acre.

Thanks Mei — glad the LiDAR navigation won you over. Enjoy the free weekends! — SUNSEEKER Tech

H
Heidi E.
The full S4 for our shady, wet yard

Between LiDAR, the weather cover, and the blade kit, it handles everything the climate throws at it. Best lawn buy in years.

So glad it's a fit, Heidi. Reach out anytime if you want tips to dial it in further. — SUNSEEKER Tech

B
Brooke H.
Excellent mower, garage lid arrived cracked

S4 flawless under our trees. Garage lid had a hairline crack from shipping. Support replaced it in a week. Pack better.

Fair review, Brooke. the garage design is a known gap and we're on it. Reach out to support if it gets in the way again. — SUNSEEKER Tech

Y
Yolanda B.
Everything included, quick firmware first

Loved it once running. There's a firmware update on first boot — ten minutes — then it's been flawless under our oaks with the garage keeping it dry.

Thanks Yolanda — appreciate you flagging the rain sensor timing. A firmware update coming soon addresses exactly that. — SUNSEEKER Tech

L
Leila B.
The version to buy if you're outdoors year-round

Garage keeps the weather off, blades keep the cut sharp, LiDAR keeps it on track under trees. Nothing left to add. Complete.

P
Preston W.
Clean cut, dry dock, zero wire

Our yard is shade and debris central. This bundle beats both — protected dock, always-sharp cut, and no buried wire.

R
Ravi Z.
No accessory shopping ever again

Blades and cover in one box. The S4 maps our tree-covered lot, mows evenly, and lives protected in its little garage. Ideal.

N
Nia P.
Weatherproof and always sharp

The garage handles our storms and the spare blades keep the finish crisp. Our shaded quarter-acre has never looked this consistent.

W
Wade T.
Worth every penny fully loaded

Weather protection, sharp blades, wire-free LiDAR mapping. My tree-covered lot looks manicured and I do nothing. This combo is the way.
