Sunseeker S4 Setup Guide: From Unboxing to Your First Mow

The Sunseeker S4 is built to be simple to live with, and that starts with a setup you can finish in an afternoon. Because it is wire-free, there is no perimeter wire to bury or pin down. Instead the S4 uses 3D LiDAR and AllSense Vision AI to scan your lawn and build a virtual map in its memory. This guide walks through the whole process in order: preparing the lawn, installing the charging station, activating the mower, connecting the app, and mapping your yard so the S4 is ready for its first run.

Before You Start: What You Need

A few minutes of preparation makes the rest of the setup go smoothly. Have these ready before you begin.

• Everything from the box. Unbox the S4, the charging station and base plate, the power adapter, and the bag of fixing screws and the wrench. Check the parts against the box-contents page in the manual so nothing is missing before you start.
• The Sunseeker app. Search for "Sunseeker" in the App Store or Google Play, or scan the QR code in the manual. Install it and create an account.
• Your phone, with Bluetooth on. The app pairs with the mower over Bluetooth during setup. Keeping your phone and the mower on the same home Wi-Fi network makes the connection step easier.
• A power point near the lawn. The charging station needs a power source and should sit within range of your home Wi-Fi.

1Prepare the Lawn

The S4 maps and mows what it can see clearly, so a tidy lawn produces a cleaner first map.

• Clear away anything loose: leaves, fallen branches, toys, garden hoses, stones, and other obstacles.
• For safety, keep children and pets off the lawn while the mower is setting up and mapping.
• Cut the grass below 80 mm (about 3 inches) before the first run. Long grass makes early mapping and cutting harder, so a quick trim first pays off.
• Walk the edges and make sure the boundary is visible. Where grass has grown over a path or border, trim it back so the edge reads clearly.

2Install the Charging Station

Where you put the charging station decides how reliably the S4 leaves and returns, so it is worth getting right.

Choose the location

• Pick open, flat, unobstructed ground so the mower can drive straight out and back in.
• Keep it within your home Wi-Fi coverage and close to a power point.
• You can place the station inside or outside the working area. For safety, route the charging cable so it runs outside the area the mower cuts.
• Leave the space in front of the station clear, with no obstacles within about 1.5 m.
• If the station sits on grass, keep that grass shorter than 2 cm so it does not interfere with docking.
• Keep the area above the station as open as possible, away from overhanging trees or eaves.

Fix it in place

Once you have the spot, secure the base plate to the ground with the supplied screws and wrench, then connect the charger and the power adapter. When the station is powered, its indicator light stays on steadily. That steady light is your sign the dock is ready.

3Activate and Charge the Mower

Before the S4 can map anything, two protective covers need to come off and the mower needs power.

• Remove the LiDAR protective cover on top of the mower. The LiDAR sensor needs a clear view to scan, and it will not map with the cover on.
• Peel the protective film off the front camera. The camera is part of how the S4 sees the lawn, so it has to be clean and uncovered. If it picks up dirt later, wipe it with a soft cloth.
• Dock the mower. Set the S4 onto the charging station and check that the charging contacts on the mower and the dock meet properly. A flashing green light means it is charging; a steady green light means the battery is full.

The S4 powers on automatically once it is charging on the station. On first start you will be asked to enter a PIN code, which protects the mower from being used by anyone else. You can change this PIN later in the settings, and the manual covers how in its "Change the PIN code" section.

4Connect the Sunseeker App

The app is where you map, schedule, and manage the mower, so the next step is pairing the two.

• Confirm the S4 is on the charging station, charging, powered on, and that you have entered the PIN.
• Turn on Bluetooth on your phone. For an easier setup, keep the phone and the mower on the same Wi-Fi network.
• Open the Sunseeker app and scan the QR code on the machine to add your mower. If scanning is not available, you can add it manually instead.
• Follow the prompts to connect to the network and bind the S4 to your account. Once it is bound, the mower shows up in the app and you are ready to map.

5Map Your Lawn

Mapping is the heart of the setup. It is a one-time scan that teaches the S4 the shape of your lawn, and it replaces the boundary wire entirely. The mower identifies the lawn edges, cruises along the boundary to gather detail, and generates an accurate virtual map for efficient mowing.

Check before you map

Run through this quick checklist so the first map comes out clean:

• The S4 is docked and the battery is above 30 percent.
• The mower is connected in the Sunseeker app.
• The LiDAR cover is open and the front camera is clean and unobstructed.
• The lawn boundary is clear and visible, with any overgrown edges trimmed back.
• Passages between areas are wider than about 0.6 m. The S4 will not map through a gap narrower than that, so widen any tight pinch points first.

Start automatic mapping

You can begin mapping in two ways: press START and then OK on the mower's control panel, or open the app and tap Mapping. The S4 then drives the boundary on its own, scanning as it goes, and keeps going until the full perimeter is recorded. Mapping pauses if you press the stop button, tap Pause in the app, or the mower meets an obstacle. Once you have checked that the path is clear, tap Resume to carry on.

When the lawn edge is not obvious

Automatic mapping works best on lawns with clear edges. Where a boundary is faint, or there are steps or drop-offs near the edge, the S4 hands over to manual remote mapping, and you can also switch to it yourself by tapping Manual. In manual mode you steer the mower along the boundary from the app. Two rules keep this reliable: stay within about 5 m behind the mower so the connection holds, and do not lift or carry the mower while it maps, since moving it by hand can spoil the map. For lawns broken up by trees, beds, and tight corners, our guide to robot mowers for complex yards pairs well with this step.

6Add Zones, No-Go Areas, and a Schedule

With the boundary mapped, a few optional touches tailor the S4 to your property, and one final step puts it to work.

Create a no-go zone

If your lawn includes a pond, a flower bed, or anything you want the mower to avoid, add a no-go zone. In the app, tap No-Go Zone, drive the mower to the start of the area, tap Start Mapping, guide it around the area, and tap Finish. The S4 then treats that space as off-limits.

Map multiple work zones

If your property has separate lawns, you can save each one as its own work zone and link them with a corridor. Create the first work zone, drive the mower to the second area and create that zone, then map a corridor between them that overlaps both. A couple of details matter here: the corridor needs to overlap each work zone so the mower can travel between them and get back to the dock, and the two work zones should not overlap each other too much, or the app will merge them into one. The S4 can store up to 100 zones across 5 maps, so even a property split into several areas fits comfortably. You can merge, split, rename, or delete zones later under Map Management in the app.

Set your first schedule

The last step turns setup into routine. In the app, open the schedule settings and choose the days and times you want the S4 to mow. From here on the lawn is maintained automatically, and you adjust the plan as the seasons change rather than pushing a mower yourself. A rain sensor pauses sessions and sends the mower back to the dock in wet weather, so the schedule looks after itself.

Tips for a Clean First Setup

• Map on a dry day. The S4 will not work well on wet ground, and a dry lawn gives the sensors the clearest read for a first map.
• Map in good light. Because the camera helps the mower see, daytime mapping with clear visibility produces a more accurate boundary.
• Tidy the edges first. A few minutes trimming overgrown borders before mapping saves correcting the map afterward.
• Keep the cable clear of the cut. Routing the charging cable outside the working area keeps it away from the blades.
• Take over at drop-offs. If the lawn ends in steps or a steep edge, switch to manual mapping near those spots rather than letting the mower approach them on its own.

Frequently Asked Questions

How long does it take to set up the Sunseeker S4?

Most owners finish in about an hour. Installing the charging station and connecting the app takes 15 to 20 minutes, and mapping a typical quarter-acre lawn adds another 20 to 30 minutes depending on its shape and how many separate areas it has.

Does the Sunseeker S4 need a boundary wire?

No. The S4 is wire-free. It uses 3D LiDAR and AllSense Vision AI to scan your lawn and build a virtual map, so you set the boundary by mapping it once rather than burying a perimeter wire. That removes the biggest install job of older robot mowers.

Do I need to charge the S4 before mapping?

Yes. The battery should be above 30 percent before you start, the mower should be connected in the app, and the LiDAR cover and front camera need to be open and clean. Mapping with a low battery can cause the mower to pause partway through to recharge.

What if the S4 cannot find the lawn edge on its own?

Switch to manual remote mapping in the app and drive the mower along the boundary yourself. Stay within about 5 m behind it so the connection stays stable, and do not lift or carry it while mapping. This is the recommended approach for faint edges, or for lawns with steps and drop-offs near the boundary.

Can the Sunseeker S4 handle more than one lawn area?

Yes. You can save several work zones and link them with corridors, and store up to 100 zones across 5 maps. That lets one S4 maintain a front lawn, back lawn, and side strips on a schedule, all from the same app.

Why does the LiDAR cover need to come off?

The LiDAR sensor on top of the mower scans the lawn to build and follow the map, and it needs a clear view to do that. The mower will not map with the protective cover still on, so removing it, along with the film on the front camera, is part of first-time setup.
