How to Store Your Sunseeker X7 / X3 Plus / V3 for Winter: Battery, RTK & Smart Mower Care

As winter arrives and lawns enter dormancy, it’s time to prepare your Sunseeker robotic lawn mower—whether you own the X7, X3 Plus, or V3 Series—for a safe, healthy seasonal rest. Proper winter storage protects your mower’s battery, RTK/Vision AI navigation system, charging equipment, and cutting performance, ensuring a smooth, trouble-free return in spring.

This guide provides the official winterization steps, based on Sunseeker user manuals and best practices, so you can protect your investment and keep your mower performing at its peak year after year.

1. Deep Cleaning Before Storage (X7 / X3 Plus / V3)

A clean automatic lawn mower is easier to store and far less prone to winter corrosion or sensor issues.

How to Clean Your Sunseeker Mower Correctly

• Remove grass buildup from wheels, undercarriage, blade discs, and crevices.
• Gently wipe Vision AI cameras (X7/X3 Plus) or front sensors (V3) with a microfiber cloth.
• Clean blade discs with a soft brush.
• Avoid pressure washers or hose jets—these can push water into electronics.
• Allow the mower to completely dry before storage.

Pro Tip: A clean mower is a healthy mower. Removing moisture-trapping grass protects the AI vision system, motors, and bearings through winter.

2. Blade Inspection & Replacement (All Models)

Even during the off-season, blade maintenance matters. Winter is the perfect time to sharpen or replace blades for better early-spring mowing.

What to Check

• Dull, chipped, or uneven blades
• Rust or discoloration
• Loose screws on blade mounting points

Need fresh blades? Replace with Sunseeker Original Blades to maintain cutting precision and safety,

3. Battery Winter Care: Protect the Lithium Core (X7 / X3 Plus / V3)

Your robot lawn mower uses high-efficiency lithium-ion batteries, which require proper winter care to maximize lifespan.

Best Practices for Battery Health

• Store your mower indoors—never leave it in freezing outdoor environments.
• Keep battery charge around 40–60% for long-term storage.
• Store in a dry, temperature-stable room (ideal: 18–25°C / 64–77°F).
• Never store near heaters or direct sunlight.
• Avoid charging below freezing temperatures.

Why this matters: proper storage prevents deep discharge, capacity loss, and cold-weather chemical damage — extending long-term performance.

4. Indoor Winter Storage Setup (All Models)

Sunseeker auto lawn mowers are built for outdoor work—but not for overwinter outdoor storage.

Ideal Storage Conditions

• Dry and frost-free
• Good ventilation
• Off the floor (use a shelf or table for insulation)
• Away from corrosive materials

Before storage, remember to:

• Turn OFF the mower completely
• Disconnect it from the charging dock
• Clean blades, wheels, and sensors

Use a Sunproof Garage for Maximum Protection

For owners who prefer to leave their mower docked or have limited indoor space, the sunproof garage provides excellent protection from weather, UV, moisture, and debris — making it a smart, low-effort investment to protect your mower during idle months.

5. Charging Station & Power Supply Winter Protection

Winter moisture, frost, and snow can damage the charging system.

Charging Station Tips

• Unplug and remove the station if you won’t mow at all during winter.
• Clean metal charging contacts.
• Keep power adapters dry and frost-free.
• If installed outdoors, relocate to a sheltered indoor area for winter.

Power Supply & Cable Care

• Coil and secure cables neatly to prevent cracking in freezing temperatures.
• Avoid sharp bends or tightly wound loops that put stress on the insulation.
• Keep all connectors and ports dry—moisture trapped in plugs can cause corrosion or charging faults.
• Store the power adapter in a dry box or elevated shelf instead of leaving it on a cold floor.

For safe, long-term winter storage and optimal spring performance, always use the official Sunseeker Charging Base together with the Sunseeker Charger, ensuring your mower receives stable, consistent power throughout the year.

6. RTK, AONavi™ & Navigation System Winter Storage (X7 & X3 Plus)

The Orion X7 and X3 Plus use Sunseeker’s advanced AONavi™ navigation system, which combines:

• RTK-GNSS high-precision positioning
• VSLAM visual mapping
• Vision AI obstacle recognition
• Centimeter-level boundary tracking

These components must be protected during winter.

How to Store RTK & Navigation Components

• Bring the RTK base station indoors—do not leave it outside in snow or freezing rain.
• Store antennas in a dry, warm place.
• Keep connectors dust-free and moisture-free.
• Avoid bending or crushing RTK extension cables.

Protecting RTK equipment ensures spring startup is faster and mapping accuracy remains reliable.

7. Magnetic Boundary Accessories Winter Care (V3 Series)

The V3 Series relies on magnetic strips and tags instead of RTK.

Recommended Maintenance

• Walk the boundary and check for lifted, damaged, or worn strips.
• Replace any bent or water-damaged connectors.
• Clean magnetic tags and ensure they remain flat.

Want original replacement strips? Use Sunseeker Magnetic Strip Kits for best compatibility.

8. Winter Lawn Preparation for a Better Spring

A few simple steps help your mower—and your grass—restart smoothly next season.

Pre-Winter Lawn Checklist

• Mow to a moderate, even height on your final cut.
• Remove branches, rocks, and toys from the lawn.
• Avoid walking on frozen or over-saturated soil.
• Clear areas where ice or water typically collects.

Healthy winter preparation leads to healthier turf and cleaner cuts in spring.

9. Firmware, App Updates & System Checkups (All Models)

Winter downtime is perfect for digital maintenance, especially for Sunseeker’s smart systems.

Use Your App to:

• Check for FOTA (Firmware Over-the-Air) updates
• Review work logs and notifications
• Update mowing schedules for spring
• Adjust multi-zone or no-go areas
• Confirm RTK binding (X7/X3 Plus)

Keeping firmware updated ensures improved navigation, performance boosts, and new safety features every season.

10. Pre-Spring Inspection: Prepare for First Mow

When temperatures rise, complete this quick check:

• Recharge the mower
• Inspect blade sharpness
• Clean cameras and sensors
• Reinstall charging dock & RTK base station
• Check wheel movement & undercarriage
• Repair any changed areas in your lawn layout

A 5-minute inspection saves time and ensures a flawless first mow.

11. FAQ: Your Most Common Winter Storage Questions

1. Can I store my mower in an unheated garage?

Only if temperatures stay above freezing. Otherwise, bring it indoors.

2. Should I leave my RTK base station outside?

No. For X7/X3 Plus, the RTK base must be stored indoors during winter.

3. Do I need to uninstall my magnetic strips (V3)?

No. They can stay on the lawn, but inspect and replace damaged pieces.

4. How charged should the battery be for winter?

Around 40–60% for long-term storage. Avoid 0% or 100% for months at a time.

5. Should I replace blades before or after winter?

Before winter is ideal—so the first spring mow is clean and sharp.

6. Can I still update firmware during winter?

Yes. Use the Sunseeker App anytime to apply FOTA updates.

7. Do I need to redo mapping in spring?

X7/X3 Plus users may need quick map verification after reinstalling RTK equipment.
