🔌 What Are Corded & Cordless Electric Lawnmowers?

• Corded electric lawnmowers run from a mains power cable. They deliver continuous power as long as they’re plugged in.
• Cordless electric lawnmowers use rechargeable batteries (usually lithium-ion) for freedom from cables and easier manoeuvrability.

Both options are cleaner, quieter, and easier to maintain than petrol mowers — but they have different strengths and trade-offs.

🆚 Head-to-Head Comparison

⚙️ Key Differences Explained

📍 1. Power & Runtime

• Corded: Offers continuous power — you won’t run out mid-mow unless you unplug. Best for frequent mowing without planning around battery life.
• Cordless: Runtime is limited by battery capacity. Newer high-voltage batteries (40 V and above) can handle medium lawns on a single charge, but very large lawns may need spare batteries.

📍 2. Mobility & Maneuverability

• Corded: You must manage the power cable, which can restrict movement and require careful routing around obstacles.
• Cordless: Cable-free freedom makes it easier to mow around trees, patios, and narrow garden features — ideal for varied lawn layouts.

📍 3. Cost & Value

• Corded: Generally cheaper upfront because you don’t pay for batteries or chargers. Great value for smaller lawns.
• Cordless: Typically costs more, especially if you need extra batteries. However, battery platforms (e.g., Ryobi ONE+, Makita 36 V, Greenworks 40 V) let you share batteries across tools, improving long-term value.

📍 4. Maintenance & Lifespan

• Corded: Minimal upkeep — just basic blade care and storage. No battery degradation to worry about.
• Cordless: Batteries age over time, losing capacity after repeated charging cycles. You may need battery replacements after a few years.

📍 5. Noise & Emissions

Both types are quieter and cleaner than petrol mowers:

• Low noise makes them ideal for residential areas.
• No fuel or exhaust fumes.
• Suitable for gardens where neighbours are close.

📏 Best Uses by Lawn Type

🌿 Small Gardens (Up to ~250 m²)

• Best pick: Corded electric mower
• Why: Unlimited runtime, low cost, and simple setup are perfect for quick mowing jobs.

🌼 Medium Gardens (~250 – 600 m²)

• Best pick: Cordless electric mower (or corded if you don’t mind cables)
• Why: Cordless freedom helps with larger areas, but a good corded mower still performs well if access to power is easy.

🌳 Larger Gardens (600 m²+)

• Best pick: Modern high-voltage cordless with spare battery
• Why: Enough runtime and no cable hassle — best when petrol isn’t your preference.
