Self-driving-level Navigation

Most mowers say “smart navigation.” What matters is whether it stays confident when your yard stops being a showroom.

Conquer any Terrain

All-wheel drive delivers strong, efficient performance across slopes up to 60% (30°), for smooth and reliable operation on uneven ground.

Made for Real Backyards

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

Built to hold its line when real life happens

What if trees block the satellite signal?
Tree canopy

What if trees block the satellite signal?

AONavi Pro fuses RTK satellite positioning with V-SLAM vision. When the sky view drops out under canopy, vision keeps the X5 on its line — so it stays accurate where wired and GPS-only mowers drift.

What happens if it gets stuck?
Stuck or off-track

What happens if it gets stuck?

Multi-sensor avoidance steers around obstacles, and if the X5 ever stalls it pauses and sends a push alert to the app with its exact location — no hunting across the yard.

Can I change boundaries later?
Complex multi-zone

Can I change boundaries later?

Create up to 100 zones, no-go areas and corridors in the app, and re-walk or edit any boundary anytime — nothing is dug into the lawn, so the map bends to your yard.

Obstacle Avoidance

Vision AI Technology

Equipped with high-tech binocular cameras and powerful computing technology the X5 detects obstacles and manoeuvres your garden with ease.

2-Year worry-free warranty

Every X5 is covered for two full years. If something fails, our team arranges a repair or replacement — just reach out.

Spare parts when you need them

Blades, wheels and casters are stocked and orderable directly — no driving to a dealer to keep your mower running.

Real human support

U.S.-based help by email and our 7/12 hotline. Have a yard-fit or setup question? Talk to us before you buy.

30-Day returns

Try the X5 in your own yard. If it isn't the right fit within 30 days, send it back.

Up and mowing in about 20 minutes

You do not need strong signal across your yard. The X5 only needs Wi-Fi where the charging base sits — the RTK antenna and mower handle the rest, even on a 3-story lot.

1 Place the base & RTK antenna

Set the charging dock near a Wi-Fi point and mount the RTK antenna where it has a clear view of the sky. No trenching, no boundary wire.

2 Walk the perimeter in the app

Drive the X5 around your lawn once from your phone, then drop no-go zones and corridors. Most yards are mapped in 20–25 minutes.

3 Schedule and forget it

Set cutting days and heights (1.6–3.2 in), and the X5 docks, charges and resumes on its own. Edit zones anytime.

FAQ

What obstacles can the X5 detect and avoid?

The Sunseeker X5 robot lawn mower uses two layers of obstacle avoidance. AI avoidance recognizes the type of object ahead and steers around it; anti-collision avoidance physically detects objects taller than about 15 inches that the camera does not classify. In everyday use it works around common yard objects such as toys, garden hoses, flower pots, exposed tree roots, stumps, chairs, water pipes, pets, and people.

Surprisingly easy to set up, excellent results

I was surprised how easy it was to setup the Sunseeker X5. Using the app on my phone, I steered the robot around the perimeter of the lawn, around the "no-go" areas, and connected the strip of grass next to the road using a "corridor". I have scheduled cutting every other day, and I water deeply on no-mow days and now I can forget about the lawn, yest I have a professional finish.

I really love this little guy!

The installation process was easier than I expected. The initial setup took a little over an hour. After using it, the lawn height is very even, and daily maintenance hardly requires any effort from me.

Clean Results with Minimal Manual Touch-Ups

Edge cutting is better than I expected for a robot mower. While occasional touch-ups are needed, overall results are clean and tidy.

Premium Convenience Worth the Investment

The price reflects the technology, but the convenience of wireless setup, smart navigation, and automation makes it worthwhile.

AWD chews through my hilly half-acre

We've got a real slope in the back that stalled every 2WD robot I tried. The X5's all-wheel drive climbs it like it's flat. Finally the whole lawn gets mowed.

Half-acre with slopes, finally handled

0.5 acre with grades that beat my old mower. The X5's all-wheel drive and virtual boundaries mapped and mowed the whole thing. Precision is impressive.

Devonte B.
Retail flagship lives up to the name

This is clearly their top tier and it shows. AWD grip, cm precision, multi-zone virtual boundaries. My sloped half-acre has never looked this good.

E
Estelle M.
Premium mower that earns it

Cm-level accuracy, all-wheel drive, edge trimming — this is the flagship for a reason. My sloped, mixed-terrain yard has never looked this consistent.

Wei K.
Steep bank? No problem

My side yard is a 30-degree bank and I dreaded mowing it. The X5 handles it with AWD and doesn't slide. Best purchase for a hilly property.

Tyrone D.
Centimeter precision is no exaggeration

The AONavi Pro navigation is scary accurate. The lines are perfectly parallel and it hits the same coverage every time. Half-acre yard looks like a golf fairway now.

H
Hollis P.
Powerful and precise, premium price

This is the flagship and it feels like it — AWD, tight precision, offset blade for edges. Only reason for four stars is it's an investment. Worth it for a big sloped yard though.

Thanks Hollis — appreciate you flagging the app onboarding. A firmware update coming soon addresses exactly that. — SUNSEEKER Tech

Isabela T.
Climbs, edges, and maps like a pro

AWD for the hills, offset blade for the fence line, virtual boundaries for the beds. This mower does it all on my half-acre and does it precisely.

S
Saoirse B.
The AWD chews through my hill

Half my backyard is a real slope and every robot mower I looked at topped out well below what I needed. The X5's all-wheel drive climbs it without slipping. Watching it power up the bank the first time sold me completely.

Thanks Saoirse — love hearing it's earning its keep. Enjoy the extra weekends. — SUNSEEKER Tech

C
Cody I.
Excellent, wanted more app detail

Performance is outstanding on my hilly half acre. Only wish is a richer app dashboard. Hardware-wise it's a five — the AWD and precision are worth it.

Thanks for the balanced take, Cody. Glad the core is working for you — reach out to support and we'll sort the small stuff. — SUNSEEKER Tech

Precision on a demanding lawn

Slopes, borders, big acreage — and the rows still come out laser-straight. AONavi Pro is the real deal.

J
Jolene Z.
Retaining-wall terraces, mowed clean

Our yard is stepped with retaining walls and grassy terraces between them. The X5 maps each level precisely, edges close to the walls, and the AWD handles the transitions. Impressive.

Loyd D.
Big sloped yard, finally automated

Half an acre on a grade used to mean an hour fighting the push mower uphill. The X5 does it overnight with AWD and parks itself. Life-changing.

Ruler-straight rows on half an acre

The stripe pattern is dead straight across the whole yard. You can see the AONavi Pro precision in every pass.

Saw it at a retailer, ordered it that night

Checked out the X5 at a retailer, was impressed, ordered it that night. Centimeter-level precision is no joke — the lines are dead straight and the edges are clean.

P
Priya V.
The precision is what surprised me most

Everyone talks about the AWD but the centimeter accuracy is the sleeper feature. No missed strips, no double-cutting. My lawn looks professionally striped.

E
Emilio M.
Steep, uneven, no problem

My lot has a 25-degree bank down to the tree line. The X5 grips and cuts it clean where my old mower would spin out. The AWD is the whole reason to buy this one.

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

Handles 0.5 acre like it's nothing

Big yard with grade changes and it just methodically covers everything. The all-wheel drive makes uneven ground a non-issue. Best mower I've owned by a mile.

W
Wilda C.
Big corner lot, no problem

Our corner lot wraps around with a lot of edge and a slope, and the X5 handles all of it — AWD on the grade, clean borders everywhere.

N
Nolie W.
Powerful, budget time for setup

The AWD and centimeter accuracy are outstanding. Just plan an evening for first-time zone setup — once dialed in, it's completely hands-off.

Appreciate the feedback, Nolie. The flagship price buys real capability, and we're always simplifying setup — reach out anytime. — SUNSEEKER Tech

Jin Q.
Saw it in a store, bought it online

Checked it out at a retailer, then ordered here. The AWD and the offset edge blade together mean it handles my slopes AND trims my borders. Nothing else did both.

Skipped a weekend of trenching

Drew the virtual boundary in the app and never buried a wire. On a half acre that saved me an entire weekend of digging.

A
Ardell V.
Traded my John Deere for this

I ran a John Deere for years and doubted a robot could match the cut. The X5's precision and AWD proved me wrong on a half-acre slope. Believer now.

Thanks Ardell — we hear you on first-time setup. Our team can walk you through zones and boundaries so it clicks faster. — SUNSEEKER Tech

Emilio F.
Worth every dollar on a big hilly lot

If you've got slopes and half an acre, stop looking. The X5's all-wheel drive and RTK precision are in another league from the cheaper mowers I tried first.

E
Emilio C.
Handles my terrain, wish setup was faster

Great on slopes and very accurate. The initial mapping of a larger yard took a while, but once done it's flawless. The AWD is the real deal on grades.

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