Description

The Sunseeker Elite X4 is a wire-free robotic lawn mower designed for lawns up to 1,200m². Using advanced 360° 3D LiDAR and Vision AI, it intelligently maps and navigates your lawn without the need for boundary wires or an RTK antenna.

Simply set it up, map your mowing area and let the X4 take care of the lawn. With intelligent route planning, obstacle avoidance and multi-zone management, it delivers efficient, automated mowing while adapting to complex garden layouts and changing conditions.

Control and manage mowing from the Sunseeker Smart App, making the X4 an ideal choice for homeowners looking for a capable, low-maintenance way to keep larger lawns looking their best.

Key Features

Designed for lawns up to 1,200m² – Ideal for medium to larger domestic lawns, with intelligent route planning for efficient and consistent mowing.

Wire-free installation – Uses virtual boundaries, removing the need to install or maintain a traditional perimeter boundary wire.

360° 3D LiDAR & Vision AI – Advanced navigation technology allows the X4 to understand its surroundings, navigate accurately and adapt to your garden.

Intelligent obstacle avoidance – 360° detection helps the mower identify and navigate around common obstacles while mowing.

Automatic 3D lawn mapping – The X4 can intelligently map your mowing area, making initial setup and ongoing lawn management easier.

Handles slopes up to 45% / 24° – Rear-wheel drive and suspension help the X4 confidently tackle slopes and more challenging areas of the lawn.

Edge-Reach cutting – Designed to mow closer to lawn edges, helping reduce the amount of manual trimming required.

Floating 6-blade cutting system – A 20cm cutting width with adjustable 20–60mm cutting height delivers a clean, consistent finish across varying lawn conditions.

Multi-zone lawn management – Manage multiple mowing areas and create no-go zones for parts of the garden you want the mower to avoid.

Smart app control – Use the Sunseeker Smart App to manage mowing, zones and mower settings from your smartphone.

Wi-Fi, Bluetooth & 4G connectivity – Multiple connectivity options help keep you connected to and in control of your mower.

Automatic charging – When required, the X4 automatically returns to its charging station before continuing to look after your lawn.

Rain detection & night mowing – Intelligent features give you greater control over when and how your mower operates.

Smart home compatible – Supports integration with Amazon Alexa and Google Assistant.

Built for outdoor use – An IPX6 waterproof rating provides protection against the conditions expected from everyday outdoor operation.
