How to Maintain Your Robotic Lawn Mower: Tips for Longevity and Performance

If you're seeking a hands-free solution to yard maintenance, the Sunseeker X3 Plus robotic mower stands out as one of the most innovative choices among modern robot lawn mowers. What sets it apart isn’t only its advanced features but also the recognition it has received from one of the most trusted voices in home improvement: BobVila.com. With over 3.8 million monthly visits, Bob Vila’s website is widely regarded as a Tier-1 U.S. media outlet for home and garden advice. Founded by television host Bob Vila, the platform is known for practical, reliable, and expert guidance. Being ranked #2 in Bob Vila’s 2025 list of “Best Robot Lawn Mowers” is therefore a significant endorsement, reinforcing Sunseeker’s position as a brand delivering quality, efficiency, and smart design.

Why the Sunseeker X3 Plus Stands Out

In Bob Vila’s July 25, 2025 roundup of the best robotic mowers, the Sunseeker X3 Plus earned the runner-up spot thanks to its blend of advanced technology, ease of use, and consistent performance. Unlike traditional mowers—or even some entry-level robotic options—this model prioritises convenience and precision in every aspect of its design.

Below are some of the standout features that caught the attention of experts and users alike.

Key Features of the Sunseeker X3 Plus Robotic Mower

High-Precision Navigation

One of the most frustrating aspects of early robotic mowers was their reliance on boundary wires. The Sunseeker X3 Plus eliminates this inconvenience with its AONavi™ positioning system, which combines RTK-GNSS satellite navigation and VSLAM visual mapping for ultra-precise route planning—even under tree cover or near buildings. Paired with Vision AI and dual-lens 3D cameras, the mower can detect and avoid more than 200 types of obstacles without requiring complex wire installations. It also allows for the creation of up to six mowing zones, complete with corridor mapping for seamless transitions between different parts of your lawn. For households with intricate yard designs, garden beds, or multiple sections, this technology delivers a truly “set it and forget it” experience.

Perfect Cut & Customisable Height

Lawn enthusiasts know that grass height matters for both aesthetics and lawn health. The Sunseeker X3 Plus robotic mower offers a versatile cutting range, trimming grass as low as 1.6 inches and up to 3.2 inches. This flexibility allows you to adapt your mowing to the season, weather, and the type of grass in your garden. The result? A consistently sharp, clean finish that enhances curb appeal while supporting strong turf growth.

Reliable Performance on Slopes & Obstacles

Unlike some robotic mowers that struggle on uneven terrain, the Sunseeker X3 Plus confidently manages slopes of up to 30°. Its advanced camera system not only detects obstacles like trees, planters, and toys but also ensures safe navigation around them—so you never have to worry about the mower getting stuck or causing damage. This makes it particularly well-suited for suburban gardens that feature varied landscaping or children’s play areas.

Quick Setup & Intuitive App Control

The Sunseeker X3 Plus was designed with everyday homeowners in mind. While some robotic mowers can be intimidating to set up, this model keeps things straightforward. With the help of its companion app, installation typically takes about one hour, including satellite receiver placement. Once operational, the smart app offers easy scheduling, zone control, and status monitoring. Whether you’re at home or away, you’ll have complete control of your mowing routine at your fingertips.

Time-Saving Convenience

Perhaps the most significant benefit of investing in a robot lawn mower is the time it saves. During peak growing seasons, the Sunseeker X3 Plus is recommended to run every third day, keeping your grass neat and uniform without requiring your attention. Over the course of a summer, this translates to hours—if not days—of yard work saved, freeing up your weekends for more enjoyable activities.

Caring for Your Sunseeker X3 Plus: Essential Robotic Mower Care Tips

Even the most advanced robotic mower benefits from regular maintenance. Proper robotic mower care ensures the Sunseeker X3 Plus continues delivering reliable, high-quality results for years to come. Here are some essential upkeep practices:

• Blade Upkeep: Change the mower’s blades at least once mid-season to maintain sharpness. The Sunseeker X3 Plus comes with spare blades and hardware, making replacements quick and hassle-free.
• Secure the Satellite Receiver: For optimal navigation, ensure the receiver rod is firmly staked into the ground. If your soil is particularly hard, consider additional supports to keep it stable.
• Zone Management: Use the app to fine-tune your mowing zones and avoid sensitive landscaping features. This is particularly helpful if you have flower beds, ponds, or other delicate areas.
• App Monitoring & Scheduling: Regularly check and update your mowing schedule to align with changing weather or seasonal growth. The app also helps you monitor performance and troubleshoot if needed.
• Routine Inspections & Cleaning: Grass clippings and debris can accumulate under the mower, especially around blades and sensors. Inspect the unit regularly and clean as necessary—always when it’s dry—to keep everything functioning smoothly.

Final Thoughts: Smart, Efficient, and Low-Maintenance

The Sunseeker X3 Plus robotic mower represents the future of yard care—where technology, efficiency, and user convenience converge. With BobVila.com’s recognition placing it among the top robotic mowers of 2025, homeowners can feel confident that this model has been vetted by industry experts and trusted reviewers.

Perfect for small to mid-sized lawns, the X3 Plus excels in precision cutting, easy navigation, and smart connectivity.
