X3 Plus

Premium performance meets sensible spend

Built to handle trees, tight edges, slopes, and multi-zone layouts with confidence—so you spend less time babysitting and more time enjoying a consistently clean cut.

Not the Best Fit If

Stays Accurate When Real Life Happens

Open lawns are the easy part. Trees, narrow side sections, and changing light are what test navigation. The Sunseeker X3 Plus fuses RTK positioning with VSLAM vision to hold a stable path in typical home yards, then follows systematic parallel routes instead of moving randomly.

True Edge Cutting

Less Time Trimming

Edge cutting is where most robot mowers leave a strip behind. The X3 Plus Ride-on-Edge design reaches over borders to cut closer along fences, beds, and hardscapes, so a 0.3-acre yard needs less follow-up trimming and fewer manual touch-ups.

Nestor E.
Chain-link fence, zero fringe

Our whole backyard is chain-link and every mower I've owned left a green stripe along it. The X3 Plus rides the boundary with the offset blade and the fence line is clean. Three months, no trimmer.

Nestor, this made our week. the magnetic strip keeps setup simple on purpose. — SUNSEEKER Tech

Lucia I.
Cuts beautifully, drops Wi-Fi at the back fence

Edge cutting is as good as advertised and it finishes every run. But the app loses the mower at the far end of the yard and the history shows gaps. A range extender fixed it. The mower didn't need it, the app did.

Lucia, 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

Simone B.
the geofence works, tested by my teenager

he carried it to the curb as a prank. my phone buzzed before he reached the mailbox. mows the 0.3 acre clean too, but the alert sold me.

G
Gavin V.
Crisp borders without me touching a trimmer

Bought it for the Ride-on-Edge and it delivered — clean hardscape edges, beds avoided, and I do nothing. Excellent mower.

A
Amir O.
Dodges the kids' toys like it can see them

Vision AI spots the ball and the chew toy and steers around in real time. No more clearing the yard before every mow.

H
Hannah S.
Edge cutting is the reason; zones took a bit

Bought it for the Ride-on-Edge and the fence line is spotless. Mapping the front/back/side zones and no-go areas took a couple passes to nail, but it's been perfect since.

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

K
Kendra P.
The string trimmer has been retired

Ride-on-Edge cuts right to the fence and paver borders. That weekly 20-minute edging chore is just gone. Best feature on any robot I've seen.

I
Indira R.
Two chores gone in one buy

Between the edge cutting and per-zone scheduling, it retired my mowing and my string-trimming. AONavi keeps it precise around the beds. Weekends back.

S
Shane W.
Great mid-size mower, app has a curve

Handles our medium lot and the obstacle avoidance is quick. The multi-zone tools work well but take a little learning. Worth it.

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

F
Franklin R.
Three zones, three schedules, no fuss

Front, back and side yard each mapped separately with no-go areas around the garden. AONavi keeps it precise across the 0.3 acre.

R
Russell M.
RTK precision after a rough base placement

Took three spots before the base had clear sky. After that, the rows are ruler straight and the cut height is dead even. Four stars for the setup detour.

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

Jared W.
Geofence warning settled my theft worry

We back onto a public path so theft was a concern. The GPS lock and geofence alert put that to rest — and the clean hardscape edges are the weekly payoff.

G
Giselle G.
Fence line looks like a service did it

The offset blade reaches edges other robots leave shaggy. Our fence and driveway borders are crisp with no hand-trimming. Sold on that alone.

W
Warren D.
Front yard Tuesday, back yard Thursday

Two zones with a gate between them. It opens nothing, I leave the gate propped, and it moves itself over. 0.28 acre total, both zones done before I'm home.

W
Wren H.
Actually cuts the strip others leave

Every robot I looked at leaves an uncut band along fences and walls. The X3 Plus's offset blade reaches it. On a 0.3-acre lot full of borders, that sealed the deal.

W
Wesley E.
Four zones, one gate, no supervision

Front, side, back, and the strip by the pool each on their own schedule. It drives through the gate between them on its own. Set up on a Tuesday evening.

Brieana G.
Worst experience ever

I’ve taken some chances on products before but none have disappointed me quite as much. This robot lawn mower certainly isn’t wireless as it requires an antenna to either be mounted to your roof or in the middle of the yard WITH A WIRE! Sure the robot itself could drive around without a wire, but that’s assuming the antenna can ever get an adequate signal. If your yard is so small that this thing could actually work then why not just buy a cheap hand mower or pay someone minimally to cut it. Installation is complex and full of failures. Save your time and money. Absolutely the worst would give zero stars if possible.

Dale i.F.
A landscaper that always shows up!

We love our X3 (we call him Detective Munch) He works hard. The set-up was pretty easy though the driving/mapping took a minute to get right. Also the cutting level dial was not described in the set-up documentation so i had to look that up. Also, being in florida, the rain sensor picks up the morning dew so the robot doesnt go out on schedule sometimes unless i dry it off or override the rain sensor. I would recommend the garage but not sure if the one on Sunseeker is worth the price as it expensive.

L
Linh K.
Front, back, and side yard all mapped separately

Multi-zone in the app is fantastic — each area on its own schedule with no-go zones around the garden. AONavi keeps it precise everywhere on our 0.3 acre.

M
Marisol B.
Great mid-size mower, app learning curve

Handles our medium yard and the obstacle avoidance is quick. The multi-zone tools work well but aren't the most intuitive at first. Worth it once you learn them.

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

C
Colton R.
Clean borders without me touching a trimmer

Bought it specifically for the Ride-on-Edge and it delivered. Hardscape edges are crisp, beds are avoided, and I do nothing. Excellent.

R
Ravi M.
The only robot that actually cuts the edges

Every other model leaves a strip along walls and fences. The X3 Plus's offset blade gets right up to them. That's the differentiator that sold me.

K
Kaitlyn E.
Edges so clean people ask if we hired a service

The offset blade reaches the borders other robots leave shaggy. Our fence line and driveway edge look professionally done. That feature alone is worth it.

Kaitlyn, this made our day — thank you for taking the time to share it. — SUNSEEKER Tech

M
Marnie N.
My string trimmer has been in the shed for a month

The Ride-on-Edge blade cuts right to the fence and paver edges. I used to spend 20 minutes edging every week — the X3 Plus made that chore disappear.

T
Travis G.
Love the edge blade, zone setup took patience

The Ride-on-Edge cutting is the star. Getting the no-go areas mapped just right took me a few passes, but once dialed in it's flawless.

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

P
Priya S.
Dodges the kids' toys like it has eyes

Vision AI spots the soccer ball and the dog's chew toy and steers around them in real time. No more picking up the yard before every mow.

D
Darnell Y.
Geofence alert put my mind at ease

We're near a busy path and theft worried me. The GPS lock and geofence give me peace of mind. And honestly the edge cutting is the best part of owning it.

I
Ivan D.
Retired two chores at once

Between edge cutting and multi-zone scheduling, the X3 Plus killed my mowing AND my edging on our 0.3 acre. Saturday mornings are mine again.

Thank you Ivan — nothing beats hearing the edge cutting is doing its job. — SUNSEEKER Tech

D
Divya K.
Smart, tidy, and no more string trimmer

Between the edge cutting, multi-zone maps, and dynamic obstacle avoidance, this thing basically retired my trimmer and my Saturday mornings.

Divya, this made our day — thank you for taking the time to share it. — SUNSEEKER Tech

D
Devonte L.
Anti-theft geofence eased my mind

We back onto a walking path so theft worried me. The GPS lock and geofence alerts made me comfortable. And the edge cutting is honestly the best part.
