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.

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.

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.

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.

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

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

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.

R
Roland P.
Great all-in bundle, level the garage pad

Everything works together well. Just give the garage a flat spot or the parking gets slightly off. LiDAR and cut quality are excellent.

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

R
Roland M.
Fully sorted in one order

Didn't want to chase accessories later, so the garage-and-blade combo was perfect. Set it all up in an afternoon. Protected, sharp, wire-free.

N
Nathaniel V.
Fully loaded and I never think about it

Garage means no weather worries, blades mean no dull cut, LiDAR means no drifting. I genuinely never think about it now.

G
Gavin S.
The complete S4 for a shady, rainy yard

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

K
Karim F.
Best value if you want it all up front

The all-in bundle saved me buying accessories piecemeal. Cut is excellent under our maples. Only note: give the garage a level spot or the door alignment is fussy.

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

R
Rashad F.
Everything included, nothing to hunt for later

Loved that the garage and blade kit came together. Set it all up in one afternoon. No wire, protected dock, sharp cut. Complete package.

R
Rodrigo F.
Fully loaded and worth every penny

Spare blades, weather cover, wire-free LiDAR mapping. Our quarter-acre under oaks looks manicured and I do nothing. This bundle is the way to go.

V
Vanessa E.
Great combo, firmware update on day one

Everything works beautifully together. Just be ready for a firmware update out of the box; took ten minutes. After that it's been flawless under our trees.

Thanks Vanessa — appreciate you flagging the initial mapping. A firmware update coming soon addresses exactly that. — SUNSEEKER Tech

L
Leila T.
One purchase, fully set for the season

Instead of ordering blades and a cover separately I got the combo. Smart move. The S4 maps my shaded lot perfectly and lives in its little garage.

Thank you Leila — nothing beats hearing the LiDAR navigation is doing its job. — SUNSEEKER Tech

L
Logan J.
Clean cut, clean dock, zero wire

Our backyard is all shade and debris. This bundle handles both — protected dock and a mower that never loses its place. Extra blades are a bonus.

V
Vernon A.
Everything in one box

No hunting for accessories later. The garage keeps the dock dry, the blades keep the cut sharp, and the S4 maps my tree-heavy lot without losing signal. Exactly what I wanted.

Y
Yuki P.
Great value all-in

The combined price beat buying the pieces separately. Mower excels in shade, garage keeps it dry, blades keep it sharp. Happy customer.

Appreciate the review, Yuki. Noted on that — we're always improving the app experience, and support is happy to help you dial it in. — SUNSEEKER Tech

K
Kaitlyn Q.
Set-and-forget with all the extras

The garage-and-blade version means I don't think about weather or replacements. LiDAR does the navigating. Best lawn decision I've made.

M
Mateo W.
The complete robot mower experience

If you want to buy once and be done, this bundle is it. Garage, blades, and the LiDAR S4. Setup was around 25 minutes and it's been perfect since.

Mateo, this made our day. Reviews like yours are exactly why we build these. — SUNSEEKER Tech
