Self-driving-level mowing for real, complex yards

Meet Sunseeker S4 — LiDAR + AI Vision navigation, wire-free setup, and systematic cutting for yards up to 0.25 acre / 1000 m².

0.25 Acres

Coverage

42% / 22°

Slope | RWD

100 Zones

Multi-Zone

3D LiDAR

360° Avoidance

Not Ideal For
  • Large lawns (above 0.25 acre)
  • Slopes too steep
Powered by 3D LiDAR and Vision AI — cordless, and never lost in the shade.

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.

Self-driving-level Navigation Means

Stays Accurate When Real Life Happens

Backed by nearly 15 years of outdoor power equipment manufacturing experience—engineered to cut like a lawn tool brand, not a gadget.

Handles 42% (22°) slopes, crosses 31.5 in / 80 cm narrow passages, and manages up to 100 zones across 5 maps.

LiDAR-led 3D mapping + systematic routes help S4 stay predictable in the yard you actually have—trees, edges, tight runs, and day-to-day clutter.

Load video:

Create virtual boundaries, No-Go zones, and channels in the app—change them anytime without digging up your lawn.

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.

Made for Real Backyards

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

Obstacle Avoidance

3D obstacle avoidance designed for daily life

Yard life changes every day—kids’ toys, hoses, furniture, pets. S4 combines 3D sensing and vision-based detection to avoid common obstacles and keep mowing moving.

Ananya K.
Inherited the kit with the house

Previous owner left the S4 and a half-used three-year kit. Remapped in twenty minutes. Blades for years.

E
Emiliano C.
A half-kit option would suit smaller lawns

Three years is more than our 0.2 acre needs. Still cheaper than piecemeal. S4 flawless under the canopy.

A
Anjali D.
Church groundskeeper, bought it for the long haul

Shaded lot behind the sanctuary. The S4 mows Fridays. The kit means the next groundskeeper inherits blades.

Anjali, planning for the next groundskeeper is exactly the thinking behind the three-year kit. Thank you. — SUNSEEKER Tech

D
Desmond R.
Lake cabin with a shaded lawn, kit lives in the boathouse

We're there every other weekend. The S4 mows between visits under the pines and the three-year kit means I never drive up to find dull blades.

Never arriving to dull blades is exactly why the kit exists, Desmond. Enjoy the lake. — SUNSEEKER Tech

C
Celia L.
Kit has no manual of its own

Which blades, which screws, how often. I guessed. The S4 has been flawless under our canopy.

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

P
Paige P.
Eighty-year-old owner, teenage blade changer

Set it up at my mother-in-law's shaded lot. Her grandson swaps blades from the kit when he visits. Nothing for her to trip on.

H
Hana H.
Used an egg carton for the packs

The kit arrived as a pile. An egg carton holds a dozen packs. S4 is superb under our oaks.

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

P
Priya B.
Kit sticker fell off

Lost track of which packs were used. Marker fixed it. S4 superb under our oaks.

Fair catch, Priya. A sticker shouldn't be the only way to track packs. We're adding printed labels to the kit. — SUNSEEKER Tech

D
Daniela R.
Bought the kit in October for next spring

Labeled the packs by month through 2029 while the mower is stored. The S4 handles our shaded quarter acre with LiDAR. One chore gone.

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

A
Abigail M.
hoa bulk order, six neighbors, six kits

all shaded quarter acres. everyone's blade shopping is done through 2029.

C
Claire D.
Whatever the oaks throw, there's a pack for it

Needles in spring, acorns in fall, leaves in between. The three-year kit sits on a shelf and the S4 keeps straight rows under the canopy. No wire anywhere.

Thanks Claire — thanks for trusting us with your lawn. That's exactly the setup we designed it for. — SUNSEEKER Tech

R
Reginald R.
Spreadsheet for each pack

I'm that person. Swap dates logged. S4 keeps straight lines under our shade and the kit will outlast the spreadsheet.

E
Esteban O.
The kit label is my hour meter

I write the swap date on each pack. The S4 keeps straight lines under heavy shade. An in-app counter would retire the marker.

C
Clifford M.
did the math at checkout: 90 cuts, 36 packs

that's a swap every 20 hours or so. the s4 mapped our tree-covered yard in one walk and i won't order blades again this decade.

L
Latoya G.
Kit arrived before the mower, confusing week

Thought it was the whole order. Mower came five days later. Both fine. Ship together.

Latoya, fair point. Bundle items should ship together, and we're working on consolidating shipments. Thanks for the patience. — SUNSEEKER Tech

N
Natalie E.
blade swap is a family calendar event now

first of every other month, my son does it for five dollars. s4 keeps straight lines under our shade and the kit will outlast his allowance.

C
Celia H.
Eleven oaks, zero wire, blades until 2029

That's the setup. Under the canopy the S4 keeps straight rows where my old GPS mower couldn't hold position. The kit sits on a shelf and I forget about it.

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

N
Nestor O.
Three years of blades, still guessing when to swap

The kit is the right idea. The S4 just doesn't tell me when a set is tired. I swap on a calendar. Under heavy shade it mows straight and never stalls.

L
Lourdes Z.
Retirement gift to myself

Quit the lawn crew the week I retired. One walk with the phone mapped the shaded quarter acre, and the three-year kit means the only recurring cost is electricity. I've never been this relaxed about a lawn.

C
Caleb T.
Ordered a parts organizer the same day

The S4 arrived with the kit in a bag. Thirty-six packs of blades need a home, so I bought a 36-slot organizer and labeled each slot by month. Mower under the oaks has been perfect.

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

G
Garrett B.
Carton dented, packs rattling

Every blade was fine. The box didn't match the price. The S4 has been flawless under our canopy.

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

V
Valeria V.
Grandpa's yard, grandkids do the swaps

He's 84 and his grandsons handle blades when they visit. The S4 maps his tree-covered lot with LiDAR, nothing to trip over, and the kit will outlast the mower.

E
Everett B.
Labeled the shelf by month

Kit arrived, I wrote dates on each pack with a marker through 2029, done. The S4's LiDAR handles our shaded quarter acre like it was built for it.

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

C
Clifford P.
first of every other month, swap day

i put it on the calendar. s4 keeps straight lines under our shade and i never run out.

M
Minh M.
Blade shopping off the list until 2029

S4 handles our shaded quarter acre with LiDAR. The three-year kit removed the one chore I kept forgetting.

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

P
Preston H.
Packs loose in a dented box

The three-year kit needs a sturdier carton. Every blade was fine, just rattling around. The S4 itself has been flawless under our canopy.

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

A
Audrey S.
Kit needs a case

S4 is superb under our oaks. The kit arrived as a loose pile of packs. A tackle box from the sporting goods aisle fixed it.

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

W
Wesley D.
lidar nav, blades for years

s4 works under the trees where satellite mowers quit. ordered once, done.

C
Claire O.
Three years of blades, zero reorder anxiety

The S4 keeps straight lines under heavy shade and I never think about blades now. The app could count cutting hours to tell me when to swap.

E
Everett H.
calendar reminder, not a reorder

i swap on the first of every other month from the kit in the shed. s4 keeps straight lines under our shade.
