Sunseeker X4 Robotic Lawn Mower | 0.25 Acre

The Sunseeker X4 is a wire-free robotic lawn mower built around a 360-degree 3D LiDAR sensing system. Instead of a boundary wire or an RTK antenna, the X4 scans its surroundings with LidarAI, capturing over 210,000 point clouds per second across a 360 x 70 degree field of view, and fuses that with Vision AI camera perception. The result is what Sunseeker calls Drop and Go setup: place the charging station, let the mower map the lawn on its own, and start mowing.

A 10 TOPS AI chip processes the sensor data, builds an automatic 3D map of your lawn, and plans intelligent paths that split complex yards into optimized zones and cut professional-looking stripes. Obstacle avoidance works in three layers, covering floating obstacles, day and night detection, and low-profile objects near the ground, with a protective bumper as the final safeguard.

The X4 cuts a 7.9 inch (20 cm) swath with six blades on a floating disc that adapts to uneven terrain, with cutting height adjustable from 0.8 to 2.4 inches. Rear-wheel drive with off-road wheels and rear suspension climbs slopes up to 45 percent (24 degrees) and clears obstacles up to 1.6 inches tall. It is rated IPX6 against water, detects rain automatically, and this configuration is sold for quarter-acre yards.

• 360-Degree 3D LiDAR: LidarAI scans over 210,000 point clouds per second in a full circle around the mower, so it perceives the yard in 3D even where camera-only or satellite-based mowers struggle, including shade and low light.
• Drop and Go Setup: No boundary wire, no RTK antenna, and no signal dependencies. Place the charging station, and the X4 maps the lawn automatically and gets to work.
• Three-Layer Obstacle Avoidance: Floating obstacle detection, day and night detection, and low-profile object detection work together with a protective bumper, day or night.
• Professional Striping: Intelligent path planning splits complex lawns into optimized zones, mows in clean parallel lines, and can even cut personalized lawn art patterns from the app.
• Floating Cut System: The 7.9 inch, six-blade floating disc follows uneven terrain for an even cut, with Edge-Reach mode working close to borders.
• Built for Real Yards: 45 percent slope capability, 1.6 inch obstacle clearance, off-road wheels, rear suspension, and an IPX6 body with automatic rain detection.
• Smart and Current: Multi-zone and no-go zone management, three return modes, Alexa and Google Assistant, OTA updates, and an anti-theft lift alert.

The X4 is made for compact yards up to about a quarter acre, and it shines where satellite-dependent mowers have trouble: tree cover, shaded corners, narrow side passages, and complex layouts. Because LiDAR does not rely on a sky view or an antenna, the X4 can work close to walls, under trees, and between obstacles while keeping centimeter-scale awareness of its surroundings.

Within the Sunseeker lineup, choose the X4 when simple setup and shade tolerance matter most. If your yard runs closer to a half acre, step up to the Sunseeker X5 Gen 2; for edge-heavy suburban yards where RTK positioning works well, the Sunseeker X3 Plus is the value pick. The X4 won a German Innovation Award for its design.

1. Place the charging station: Set it on flat ground at the lawn edge and secure it with the included nails.
2. Plug it in: Connect the station charger to the charging station and a power outlet.
3. Charge the mower: Dock the X4 and let the battery charge before the first mow.
4. Connect the app: Download the Sunseeker app and pair with the mower.
5. Map automatically: Start Drop and Go mapping; the X4 builds a 3D map of the lawn on its own, then lets you set zones and no-go areas.
6. Start mowing: Choose your cutting height (0.8 to 2.4 inches), set a schedule, and let the X4 take over.
