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.

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.

Retail flagship, and it shows

Saw it at a store display and the build quality sold me. Half acre, real slopes, centimeter-accurate paths. Best mower I've owned.

AWD ate my slope for breakfast

My back hill pushed 30 degrees and stopped two other robots cold. The X5's all-wheel drive just marched up it in straight lines.

Great mower, app boundary setup took me a couple tries

Cut quality is excellent and the AWD handles my sloped half acre with ease. My only nitpick is that drawing the virtual boundaries in the app took me two or three attempts before I got them clean — the walk-the-perimeter step was a little finicky the first time. Once it was set, flawless. Still an easy 4 stars, would've been 5 with a smoother boundary wizard.

Kevin — fair point on the boundary wizard, and thanks for the detail. We're actively refining the perimeter-mapping flow in an upcoming app update to make that first pass more forgiving. Glad the AWD and cut quality are treating your slope well. — SUNSEEKER Tech

Multi-zone made my weird lot easy

My property is broken into three chunks by a driveway and a shed. I set each one as its own zone and the X5 works through them on a schedule. The virtual boundaries let me carve out the garden and the trampoline area with no fuss.

P
Priya M.N.
cm precision is not marketing fluff

I was skeptical about the whole centimeter-level accuracy claim. Then I watched it edge along my flower beds with maybe a finger's width to spare, lap after lap, same line every time. AONavi Pro clearly knows exactly where it is.

Thanks Priya — the upgraded RTK + V-SLAM fusion in AONavi Pro is exactly what keeps those bed lines tight pass after pass. Enjoy the tidy edges. — SUNSEEKER Tech

cm-level? believe it

The edges it leaves are so straight my neighbor asked if I switched landscapers. Nope, just a robot.

Saw it at a dealer, ended up buying online

Bought after I saw one running a demo lawn at a retail store near me. The online-exclusive X5 was the same unit, so I ordered it and don't regret it one bit.

Handles my steep side yard

The spec says 60% grade and I have a section that's got to be close to that. It powers through where I honestly expected it to slide. Impressive traction.

M
Michelle B.T.
Very good, wish the schedule editor was simpler

Precision and slope climbing are top notch and it looks premium in person, exactly like the demo unit I saw in the store. Small gripe: editing the weekly schedule per zone felt clunky and I had to poke around to find settings. Not a dealbreaker at all, just a bit of a learning curve. Four solid stars.

Thanks Michelle — appreciate the honest feedback. Per-zone scheduling is on our list to streamline, and our support team is happy to walk you through a couple of shortcuts in the meantime. Enjoy the X5. — SUNSEEKER Tech

half acre, zero wires, done

No boundary wire to bury. Set up the virtual borders in the app and it handles my roughly half-acre lot without me touching a thing.

AWD is the real deal on my hill

Half my back yard is a nasty grade and every wheeled mower I owned would spin out. The X5 just crawls right up it. All-wheel drive plus the tread means it hasn't gotten stuck once in six weeks.

R
Robert F.
Skeptic here. Converted.

I did not believe a robot could deal with my yard. Between the slope near the shed and the flower beds I figured it'd get stuck hourly. Three weeks in and it has gotten stuck exactly zero times. The virtual boundaries kept it out of the beds without me burying a single wire. I was wrong and I'm happy to say so.

K
Karen S.
Precision on the corners sold me

Coming from a big commercial zero-turn I used on my property, I was worried a robot couldn't match the finish. It doesn't cut faster obviously, but the consistency day over day is better than I ever managed. The cm-level positioning means it hits the same clean lines every time.

Finally something that handles my half acre without complaints

We've got right around 0.5 acre with a couple of tricky grade changes near the patio. I set up three zones in the app and let it run on a schedule. The offset blade gets tight against the retaining wall so I barely touch the trimmer anymore. Cutting quality has been consistently even, no scalping on the uneven spots. For a mid-sized yard with slopes this thing is a genuine workhorse and the precision from the RTK plus V-SLAM combo really shows in how repeatable the paths are.

Aisha — love hearing the offset blade is saving you trimmer time along that retaining wall, that's exactly what it was built for. Enjoy the free weekends. — SUNSEEKER Tech

GREAT MACHINE FOR HILLY LOTS

My property is basically a ski slope in places. 30 degrees on the side yard. The AWD grips like nothing I've owned and the multi-zone setup let me tell it to be extra careful over there. Very impressed.

P
Priya H.N.
Good but the virtual boundary took some fiddling

The mower itself is excellent and the AWD is impressive on my incline. My only gripe is that drawing the virtual boundaries the first time was a bit finicky in the app and I had to redo one zone twice before it stuck. Once dialed in, it's flawless. Knocking one star just for the setup fuss.

Priya — fair note on the boundary drawing, and thanks for the patience getting it dialed in. We're refining the zone-editing flow in an upcoming app update to make it more forgiving on the first pass. — SUNSEEKER Tech

Raymond E.
Retired and thrilled

I'm 68 and pushing a mower around half an acre in July heat was getting to be too much. My son helped me get the X5 going and now I just watch it from the porch. The offset blade even trims right up against the fence line so I barely have to touch the trimmer anymore. Best money I've spent on the yard in years.

Nathan P.B.
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

D
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

FINALLY DITCHED MY HUSQVARNA

Ran a wired Husqvarna for four years and was tired of the guide-wire breaks every spring. Switched to the X5 for the wire-free setup and the AWD. Night and day. It climbs my terraced back slope the Husqvarna never could, holds its lines to the centimeter, and the app actually makes sense. The offset cutting deck getting close to hardscape edges is a nice bonus I didn't expect.

G
Gregory B.
solid, one quirk

Cuts beautifully and climbs my slope no problem. Only reason it's four stars is the app occasionally loses connection to the mower and I have to reopen it. Minor but noticeable.

Gregory — appreciate the honest rating. Intermittent app reconnects are usually tied to router band-switching; our support team can walk you through pinning the 2.4GHz band, and a firmware push this quarter improves reconnect handling. — 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
