🧠 How to Choose Your Price Point

  • Medium lawns: ~£800–£1,300
  • Large lawns: ~£1,200–£1,800+

Match mower rating to lawn area plus a bit extra — don’t under-spec it.


🌳 2. Garden Layout & Obstacles

  • Simple, flat lawns → cheaper robots
  • Complex lawns with trees, patios, narrow paths → mid-range to premium
  • Slopes, uneven turf → upper mid to high end

🔋 3. Features You Actually Need

FeatureWorth Paying For
Smart navigation/maps⭐⭐⭐⭐
Rain sensing & scheduling⭐⭐⭐
GPS anti-theft tracking⭐⭐⭐
Boundary wire⭐⭐●
App control⭐⭐⭐

Only pay extra for features you’ll use regularly.


💡 Cost vs Time Saved

Robotic lawnmowers pay off not just in price, but in time saved mowing manually — especially through peak growing seasons. A smart robot that mows regularly can produce noticeably healthier lawns with less manual effort.

Compare this to:

  • A few hours per week spent mowing manually
  • Petrol or battery push mower costs
  • Time you could spend elsewhere

🔧 Running Costs to Expect

Beyond the purchase price, budget for:

  • Blade replacements: ~£10–£30 annually
  • Battery replacement (every 3–5 years): ~£100–£300+
  • Electricity for charging: low cost
  • Boundary wire repairs (if used): occasional

These costs are generally lower than petrol mower servicing.
