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.

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.

Maple samaras everywhere except the dock

Helicopter seeds coat the yard in spring and the dock stayed clean under the shelter. S4 mowed through them.

F
Fernanda O.
City lot, shelter on the stoop

Our shaded quarter acre is wall to wall trees. The S4 maps it with LiDAR and the shelter fits on the back stoop out of the rain.

Fernanda, a back stoop under tree cover is the kind of lot GPS mowers give up on. Glad the LiDAR map and the shelter both fit. — SUNSEEKER Tech

M
Monique W.
Wish the shelter had a window

I'd like to see it docked without lifting the lid. Dock has stayed dry through leaf season.

L
Leonard D.
hydrangea bed hides the shelter completely

you can't see it from the patio. s4 backs in under the maples every run.

R
Reginald D.
Pine straw slides right off

Longleaf pines over the whole back yard. Before the shelter the dock was buried every morning. Now the pitched roof dumps the straw to the side and the S4 docks clean. LiDAR never loses the map under the canopy.

Longleaf straw burying the dock every morning is a very specific problem, Reginald, and we're glad the pitched roof solved it. — SUNSEEKER Tech

D
Dana G.
Frost on the roof, none on the contacts

First cold morning this week. Shelter was white, dock underneath dry. S4 ran at ten under the trees.

L
Lin B.
Possum slept under it, mower docked next to him

Found them side by side one morning. Both fine. S4 kept its schedule under the pecans.

X
Ximena V.
Roof collects leaves, blow it weekly

The shelter keeps leaves off the dock but they pile on top. A steeper roof would shed them. S4 under the trees has been reliable.

R
Rodrigo O.
Hinge squeaks every time the mower docks

A drop of oil fixed it, but it should not need it in month two. S4's mapping under our maples is excellent.

Rodrigo, a hinge shouldn't need oil in month two. We're looking at the hinge material, and support can send a replacement if it comes back. Glad the mapping under the maples is excellent. — SUNSEEKER Tech

C
Clifford H.
Rain chain splashes, dock stays dry

The chain is three feet from the shelter. Dock has never been wet. S4 finishes every run under the canopy.

A
Arjun M.
fog machine on halloween, dock stayed dry

ran it all evening by the patio. shelter kept the moisture off the charger. s4 mowed under the oaks the next morning.

M
Marcus B.
Sweetgum balls bounce off the shelter roof

They drop by the hundred in October. The roof takes them, the charging plate stays clear, and the S4 maps under the canopy with LiDAR like nothing is happening.

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

C
Caleb U.
Shelter wobbles on pavers

Two of the four feet sit on a paver seam, so it rocked a bit when the mower drove in. A rubber shim from the hardware aisle fixed it. The S4 itself has threaded our quarter acre of oaks since July without a single stall.

Good shim, Caleb. We're looking at adjustable feet for uneven pavers so nobody needs a hardware run. Glad the S4 has been stall-free since July. — SUNSEEKER Tech

H
Hector M.
Thursday leaf crew next door, dock unaffected

They blow everything toward our fence. The shelter catches it. S4 finished every run under our oaks through leaf season.

Appreciate the detail, Hector. thanks for trusting us with your lawn. Enjoy the weekends back. — SUNSEEKER Tech

T
Tess W.
Lid latch froze shut one morning

Cold snap, dew froze, latch stuck. Warmed it with my hand. The S4's mapping under our maples is excellent, the latch needs a cold-weather rethink.

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

O
Owen P.
Shelter hides the status LED

I liked glancing at the dock light. Now I check the app. Small trade for a dry dock under our maples.

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

M
Meredith L.
Shelter rides on a slight slope, needed shims

Our patio corner isn't level and the shelter rocked until I shimmed one side. Fine since. S4 under the oaks has been flawless.

Thanks Meredith — fair note on that. We're working on it and appreciate the honest four stars. — SUNSEEKER Tech

G
Garrett D.
Neighbor's sprinkler overspray soaked my old charger

Their heads throw water over the fence every morning. The shelter keeps the S4's dock dry through it. Under our maples the LiDAR map has never lost its place.

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

E
Erin S.
Good pair, the shelter is lighter than it looks

Two bricks on the base settled it in wind. S4 under our trees has been reliable.

R
Rosario V.
hoa wants docks hidden, shelter passes

our hoa flagged the bare charger. the garage counts as 'screened equipment' in their book. s4 mows the shaded quarter acre and parks out of sight.

M
Marcus B.
Pine needles slide off the roof instead of the dock

Our pines shed constantly. The shelter roof sheds them. The S4 maps under the canopy with LiDAR and finishes every run.

M
Meredith W.
Dock looks new after a full season

Pollen, rain, leaves, all kept off. S4 finished every run under our oaks.

Meredith, this made our week. thanks for trusting us with your lawn. — SUNSEEKER Tech

P
Paloma O.
Mower superb, shelter door hinge pin walked out

The S4's mapping under our maples is excellent. The hinge pin on the shelter lid worked loose after a month. A cotter pin fixed it. Should be captive.

Paloma, thank you for the candid feedback. You're right about the app — our team is addressing it, and support can walk you through the current workaround any time. — SUNSEEKER Tech

N
Nora H.
october ladybugs everywhere except the dock

they coated the siding for a week. the shelter kept them off the charging plate. the s4 mowed under the trees through all of it.

H
Hana P.
Added two bricks, stopped the wobble

The shelter is lighter than I expected and shifted in a storm. Bricks on the base fixed it permanently. The S4 under our trees has been spotless.

Thanks Hana — fair note on base station placement. We're working on it and appreciate the honest four stars. — SUNSEEKER Tech

R
Rodrigo V.
cat sleeps on the garage roof

that's the review. s4 mows under it, under the oaks, and comes back to a cat-topped shelter. lidar never loses its place.

H
Harold R.
Leaf blower doesn't reach the dock anymore

Blowing the patio used to coat the charger in debris. The garage shields it. S4 finished every run under our oaks.

Thanks Harold — glad the garage is keeping the dock dry. That's exactly the setup we designed it for. — SUNSEEKER Tech

J
Joaquin Z.
Tampa summer test passed

Four months of 3pm thunderstorms. The shelter never let the dock sit wet and the S4 parks itself at the first drops. Live-oak shade is a non-issue with LiDAR.

A
Aaliyah B.
garage saved the dock from the sprinklers

the only dock spot was in a sprinkler arc. garage keeps it dry. s4 handles the shade from the oaks where our gps mower quit.

N
Natalie K.
under the deck stairs, finally a dock spot

the garage made a cramped spot under the stairs work. s4 backs in clean. mows our shaded lot while we're at work.
