As New Hampshire homeowners embrace the ease of robotic lawn mowers, it’s clear that convenience, quiet performance, and precision cutting have transformed local yard care. But while these high-tech machines take the sweat out of mowing, they still require regular care and maintenance to stay sharp—literally and figuratively.
At Seacoast Power Equipment, we know that skipping routine maintenance can lead to reduced performance, battery failures, and uneven mowing results. That’s why we’ve created this complete robotic mower cleaning guide—a comprehensive resource to help Granite State homeowners keep their smart mowers in top shape throughout the season.
Whether you’re in Portsmouth, Exeter, or Concord, our expert team is here to ensure your mower runs efficiently, safely, and for years to come.
Why Robotic Lawn Mower Maintenance Matters
A robotic lawn mower is an investment in your home, lawn, and lifestyle. And like any smart piece of outdoor equipment, it needs upkeep to deliver peak results. Here’s why maintaining your mower matters:
1. Performance Optimization
Dull blades, clogged sensors, or dirt-covered wheels will drastically reduce mowing effectiveness. A well-maintained mower provides consistent, clean cuts for a healthier lawn.
2. System Longevity
Routine cleaning and inspections prevent premature wear and tear, helping your mower last for seasons—not just months.
3. Safety and Autonomy
Proper maintenance ensures safety sensors function correctly and that the mower can avoid obstacles, navigate slopes, and return to its dock without fail.
4. New Hampshire-Specific Challenges
Our humid summers, muddy springs, and pine-needle-littered lawns present unique challenges. Localized maintenance—tailored for NH terrain—is key.
Robotic Mower Cleaning Guide: Routine Maintenance That Pays Off
Robotic mowers operate several times a week. That means dirt, debris, and moisture can quickly accumulate. Here’s how to keep yours spotless and fully functional.
🔧 Weekly Cleaning Checklist
- Blades: Remove and brush clean after every 1–2 mows. Wipe with a dry cloth and inspect for nicks.
- Deck Underside: Use a plastic scraper to clear clumped grass—never use water directly unless rated waterproof.
- Wheels: Remove grass build-up for better traction. Clean tread with a brush.
- Charging Contacts: Gently wipe contacts on both mower and dock with a microfiber cloth.
- Sensors: Clean with a cotton swab or soft cloth to avoid navigation errors.
💡 Tip: New Hampshire lawns often leave sap and pollen behind—be extra diligent during spring and early summer.
Key Maintenance Areas to Focus On
1. Blade Maintenance
Your mower’s cutting efficiency depends entirely on the condition of its blades. Dull blades tear grass instead of slicing it, which leads to yellowing and disease.
- Sharpen every 20–30 operating hours
- Replace every 1–2 months if heavily used
- Always use manufacturer-approved replacement blades
- Wear gloves and follow safety protocols when removing blades
We carry OEM replacement blades for popular models like Husqvarna Automower®, Toro Robotic Mowers, and Kress Mission™ series at our New Hampshire service center.
2. Battery Care
The battery is the beating heart of your mower. If it’s weak, your mower may not complete cycles or return to the dock correctly.
- Clean terminals monthly
- Avoid deep discharge—keep charged between uses
- Replace every 2–4 seasons depending on usage
- Store batteries at 50–70% charge over winter
If your mower no longer holds a charge, bring it to Seacoast Power Equipment—we offer battery diagnostics, sales, and safe installation.
3. Sensor Accuracy
Dirty sensors = poor navigation. And poor navigation = damaged plants, stuck wheels, or incomplete mowing.
- Clean sensors weekly
- Use a soft, dry brush or microfiber cloth
- Check alignment monthly
- Update firmware regularly through the app or service dealer

If you’re having performance problems, the solution is often simpler than you think. Here are some of the most common robotic mower issues we solve for New Hampshire clients:
