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.

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.

Good machine, one caveat on wet steep grass

Want to be fair because overall I'm happy — the AWD really does climb and the cut is clean. My honest caveat: on the steepest section when the grass is still wet in the morning, it'll occasionally pause and reposition rather than power through. I ended up scheduling that zone for later in the day once things dry and the issue basically went away. A dedicated wet-traction mode would make it a 5 for me. Not a dealbreaker, just something to plan around if your steep part stays damp.

This is genuinely useful, Nathan — you're right that the steepest wet section is where traction gets conservative, and scheduling it for a dry window is the workaround we'd recommend today. A wet-traction mode is something our firmware team is actively looking at, and we'll follow up through support with mapping tips for that zone in the meantime. Thanks for the measured write-up. — SUNSEEKER Tech

Danielle W.F.
Does what it says, minor gripe

Handles my sloped side yard great and the precision is legit. The one thing I'd change: I'd like a couple more granular scheduling options in the app. Small stuff. Still a 4 because the core job is done really well.

Fair ask, Danielle — more granular scheduling is on our radar and feedback like yours pushes it up the list. Thanks for taking the time. — SUNSEEKER Tech

K
Kevin P.A.
Great mower, app has a small learning curve

Cut quality and hill performance are excellent, no complaints there. Only nitpick is drawing the virtual boundaries the first time took me a couple tries to get the mulch beds excluded cleanly — once I understood how the mapping worked it was fine. Would recommend.

Appreciate the honest note, Kevin — the first boundary draw does trip a few folks up, and we're working to make the mapping step more forgiving. Glad the hills and cut are treating you well. — SUNSEEKER Tech

Rosa M.
Quietly impressed

Neighbors didn't even notice it running the first week. It's that quiet, and the cut is genuinely even. AWD makes short work of the little rise between my yard and the treeline.

Love that the neighbors didn't clock it, Rosa — quiet coverage on that rise is the whole idea. Thanks for the kind words. — SUNSEEKER Tech

Tom B.
Ex-Husqvarna owner, no regrets switching

Ran a boundary-wire Husqvarna for years and got tired of splicing the wire every spring after aeration nicked it. No wire on this one, and it actually climbs the berm my old one used to give up on. Setup was an afternoon of drawing zones on my phone.

Half acre, real grade, zero babysitting

Property's about a half acre with a decent roll to it — front dips toward the street and the side yard climbs toward the fence. I was skeptical a robot could handle mixed terrain like that without getting stuck somewhere. It hasn't once in six weeks. The virtual boundaries in the app were easy to draw and I re-drew the mulch bed exclusions twice with no hassle. This replaced a $180/month service.

M
Marcus P.E.
Precision is the real story here

Everyone talks about the AWD but for me it's the centimeter accuracy that sold it. My beds have curvy edges and it traces them without scalping or leaving a fringe.

Walter K.
no more wrestling a mower on the slope

I'm 63 and the slope by my driveway was the part of mowing I dreaded. This thing takes it without slipping. Set the boundaries in the app and forgot about it.

Sixty-three and letting the robot take the scary slope — that's exactly the point, Walter. Glad it took the dread off your list. — SUNSEEKER Tech

P
Priya D.R.
SAW IT AT A DEALER, BOUGHT IT ONLINE

Watched one running in a showroom display and honestly thought it was staged. Nope. Mine does the same thing in my actual yard. The precision is a little uncanny — it comes back to within an inch of where it left off. Half acre done while I'm at work.

Hector P.V.
Great most days, wet slopes need patience

I want to be fair because I do like this mower — cut quality and the AWD are excellent on dry ground. Where I've had trouble is my steepest section after morning dew or rain; it'll slip a little and pause rather than push through, so I've learned to schedule that zone for later in the day once things dry out. Works fine once I did that. I'd honestly love a dedicated wet-traction mode in a future firmware update, but as-is it's a solid unit and the workaround isn't a big deal.

You're being more than fair, Hector, and you nailed the right workaround — scheduling the steepest zone for drier hours is exactly what we'd suggest today. A wet-traction handling mode is genuinely on our firmware roadmap, and I'm logging your note against it. If you want, our support team can help fine-tune that zone's timing. — SUNSEEKER Tech

Finally something that handles my hill

Half my backyard drops off at a pretty mean angle and every wheeled robot I looked at would've spun out on the wet grass. The X5's all-wheel drive just claws right up it, no drama. Cuts clean lines too. Wish I'd stopped renting a crew years ago.

D
Denise A.
Strong on hills, small learning curve

No complaints about the hardware. It powers up grades that impressed me and the precision is legit. Only reason it's four and not five is I wish the app remembered my last edited map a little better between sessions. Minor. Would buy again.

Thanks for flagging the map-session thing, Denise — that's useful feedback and I've passed it to the app team. Really glad the climbing and precision are landing for you. — SUNSEEKER Tech

G
Greg Y.
Good mower, app took me a minute

Really happy overall. Cut quality is excellent and the AWD gets up my back slope fine. My one nitpick is drawing the virtual boundaries in the app the first time was a bit fiddly and I had to redo one corner. Once it was set, though, flawless.

Appreciate the honest note on the boundary setup, Greg — that first-time draw can be finicky and we've got a walkthrough in the app help section that smooths it out. Glad the AWD is handling your slope. — SUNSEEKER Tech

Y
Yolanda C.P.
Great on dry days, cautious on the steep wet part

Everything about the cut and the precision is good, and I don't want this to read as a pan. The reason it's three stars for me is a steep, shaded strip that stays damp — the mower is appropriately cautious there and will occasionally stop and ask for help until it dries out. I now set it to run later in the day and it's much better. A rain-delay-aware schedule for slope areas would earn the fifth star from me.

Thank you Yolanda — cautious behavior on a damp, shaded steep strip is the mower protecting itself, but we hear you that a slope-aware rain delay would make that seamless. That feedback is going straight to the scheduling team, and support can follow up with the best schedule settings for your layout in the meantime. — SUNSEEKER Tech

Otis B.
Excellent on slopes, careful when they're wet

No complaints about the climbing power on dry grass — it's genuinely impressive on my hill. One honest note: on a heavy-dew morning it was a little more cautious on the steepest wet section, which honestly I'd rather it be. I just schedule it for later in the day now and it's perfect.

Smart scheduling, Otis — easing off a wet, steep section is exactly the cautious behavior we design in, and a later-in-the-day run is the perfect workaround. Glad the climbing power is impressing you on the dry. — SUNSEEKER Tech

Camille D.
BIG YARD, BIG HILL, NO PROBLEM

I've got grade in three directions and this is the first robot that just deals with it. AWD earns its keep. Precise, quiet enough, and I stopped paying a lawn service that was killing me monthly. Wish I'd done this two summers ago.

Two summers earlier would've been great, Camille — but we're just glad the AWD finally tamed that three-way grade and got you off the monthly service. Enjoy it. — SUNSEEKER Tech

virtual boundaries beat burying wire

Drawing the boundary in the app instead of trenching wire around a half acre? Yes please. Took the afternoon off the whole project. Handles my slopes like they're flat.

D
David K.N.
Good mower, be smart about wet slopes

I want to be fair because the AWD is genuinely strong on dry grade — it climbs my steepest section fine most of the time. My honest three-star reason: after a heavy rain it will slip and pause on the wettest part of my steepest bank, and I've learned to just schedule around the weather so it runs on a dry afternoon. That solves it, but it'd be great to see a dedicated wet-traction firmware mode down the road. Not a dealbreaker, just managing expectations.

This is fair and we appreciate you laying it out so clearly, David. Wet slip on saturated grade is a real limit, and scheduling for a dry window is exactly the right workaround for now. A wet-traction handling mode is on our firmware roadmap, and our support team can flag your account so you hear when it ships. — SUNSEEKER Tech

Skeptical husband, converted

I told my wife these things were a gimmick. She bought it anyway. Three weeks later I'm the one bragging to the guys at work about how it handles our uneven backyard and holds a straight line better than I ever did with the push mower. Fine, I was wrong.

Renee C.
solid buy for a graded lot

Climbs my hill, cuts even, quiet enough. Only small thing is I wish it charged a hair faster on the biggest mow days, but it always finishes the yard. Good product.

Thank you Renee — noted on the charge time for those long sessions; splitting the yard into two zones on your busiest days can help it finish faster. Really glad it's handling the hill. — SUNSEEKER Tech

Rebecca E.L.
Big yard, real grade, no drama

We've got a little over half an acre that rolls quite a bit and I was skeptical a robot could keep up. It keeps up. The all-wheel drive is the difference maker on the sloped sections where I've seen two-wheel units just give out. Quiet too, which the neighbors appreciate.

Love hearing the AWD earned its keep on that rolling half acre, Rebecca — that's exactly the terrain we built it for. Thanks for the kind words. — SUNSEEKER Tech

PRECISION IS NO JOKE

The centimeter-level tracking is real. It lays down these near-perfect lines and doesn't wander into the flower beds. I set virtual boundaries around the garden in the app and it respects every one of them. Techie in me is very happy.
