MoeBot X3 First Setup and Review | Robot Lawn Mowers Australia

Moebot Sunseeker X3 Review & First Setup Guide

If you’ve been looking at the new Moebot Sunseeker X3, this is my full hands-on setup and review after running it across three different yards at my property. I’ll take you through the installation process, how it performed on real Aussie lawns, and who this mower is best suited for.

Like all of our reviews, I don’t just unbox the mower — I test it in the field, check the app, run it on slopes, and see how it handles the challenges real homeowners face.

First Setup & Installation

The first step with the Sunseeker X3 is downloading the Sunseeker app, setting up your account, and pairing the mower. Pairing is done with a QR code on the back of the unit, which can be a little fiddly, but once connected it walks you through everything: mowing height recommendations, charging station installation, and antenna setup.

One important detail: the X3 comes with two different power supplies (one for the charging station, one for the RTK antenna). Both look the same, so you need to pay attention to the labels to avoid mix-ups.

Charging Station Placement

The charging station isn’t just where the mower rests — it’s the reference point for the whole mapping system. That means it needs to be installed in a location with clear sky view to ensure accurate GPS. If you move the charging station later, your maps will shift too.

RTK Antenna

Unlike some other brands, Sunseeker lets you move the RTK antenna later without redoing your maps. That’s a big win, especially if you want to trial it low, then relocate it to the roof for the best satellite visibility. For long-term use, I strongly recommend mounting it as high and open as possible.

Mapping Your Lawn

The mapping process is straightforward. You drive the mower around the edges with the app, set up work zones, and create corridors to connect multiple areas. I tested it across three separate lawns with pathways between them, and the X3 handled the mapping well. One standout feature is the ability to create corridors even before defining a new mowing zone, which adds a lot of flexibility.

Performance & Real-World Testing

Cut Quality

The X3 is a front-wheel drive floating deck mower, and I was impressed with how it handled uneven edges and slopes. For a two-wheel drive machine, it had more traction than I expected — even climbing a steep, rough concrete ramp that no other front-wheel drive mower I’ve tested has managed.

It left a neat, consistent finish, with only the typical challenges around tight trees and corners. Along borders, it did a solid job but would benefit from an option to run multiple edge laps.

Slopes & Terrain

Rated up to about 25–30% slope, the X3 performed better than expected, even on wet grass. It did spin its wheels occasionally on the steepest areas, but once conditions dried out, it managed confidently.

Runtime & Charging

Rated for 800 m², I found that accurate. In fact, runtime exceeded expectations:

• 2 hours minimum, up to 2 hours 40 minutes per charge.

• Charge time back to 80% took about 1 hour, and full charge around 1h20–1h35.

This translates to about 160 m² per charge, which is important for yards where the mower needs to be carried between the front and back lawns.

Navigation & App Features

The app is one of the highlights. It logs mowing paths, shows completed work with precise lines, and makes it easy to add safe zones, no-go zones, or virtual walls. Scheduling is extremely simple — even a beginner could set it up in minutes.

Connectivity was also solid, with the RTK antenna delivering up to 250 m range while still sending notifications back to my phone.

Pros & Cons of the Moebot Sunseeker X3

Pros

• Strong traction for front-wheel drive — handled slopes and edges better than expected.

• Floating deck gives a clean, even cut.

• Runtime exceeds rating (2+ hours per charge).

• Flexible antenna placement — move it later without remapping.

• User-friendly app with advanced mapping tools, safe zones, and corridors.

• Affordable entry into RTK mowing compared to premium European brands.

Cons

• Charging station is the reference point — must be installed with good sky view, and can’t be moved without remapping.

• Front-wheel drive limitations — won’t suit very steep or slippery yards.

• Steering control in mapping mode can feel overly sharp.

• Single edge cut lap only — no option for double or triple borders.

Who Is the Sunseeker X3 For?

The Moebot Sunseeker X3 is ideal for:

• Lawns up to 800 m² (possibly more with smart scheduling).

• Properties with front and back yards — runtime per charge makes it easy to carry between areas.

• Homeowners who want advanced mapping and app control without paying premium prices.

• Relatively flat to moderate yards with some slopes, but not extreme terrain.

If you want a reliable, entry-level RTK robot mower that delivers real value for money, the X3 is a strong contender in 2025.

Final Thoughts

After a full test across multiple yards, slopes, and conditions, I’d rate the Moebot Sunseeker X3 as one of the best-value RTK mowers currently available in Australia. It isn’t perfect — no front-wheel drive mower is — but for the price point, the performance, runtime, and app features make it a smart buy for medium-sized suburban lawns.
