The Real Annual Cost of Running a Robot Mower You've seen the sticker prices — $799 to $4,999. But what about the ongoing costs? One of the biggest advantages of robotic mowers is how cheap they are to operate. Here's the full breakdown. Electricity: $15-$50/Year Robotic mowers are incredibly energy efficient. A typical mower uses 20-30 kWh per month during the mowing season (roughly 7-8 months in most US climates). At the national average of $0.16/kWh: Small mower (Navimow i105N): ~15 kWh/month × 7 months × $0.16 = ~$17/year Medium mower (GOAT G1, Navimow i108E): ~25 kWh/month × 7 months × $0.16 = ~$28/year Large mower (LUBA 2, 450X EPOS): ~35 kWh/month × 7 months × $0.16 = ~$39/year Compare that to a gas mower: $100-$200/year in fuel alone, plus oil changes. The electricity cost of a robot mower is almost negligible. Replacement Blades: $20-$60/Year Robotic mowers use small, replaceable blades (often razor-style or disc blades) that should be swapped every 1-3 months during mowing season. Blade packs typically cost $10-$20 for a set: Husqvarna models: ~$15 per blade pack, replace every 2-3 months = ~$30-$45/year Mammotion/ECOVACS: ~$12-$20 per set, replace every 2 months = ~$36-$60/year Segway Navimow: ~$10-$15 per set, replace every 2-3 months = ~$20-$40/year Worx Landroid: ~$10 per 12-pack, individual blade replacement = ~$20-$30/year Maintenance: Minimal Unlike gas mowers, robotic mowers have no engine oil, spark plugs, air filters, or belts. Annual maintenance consists of: Cleaning the underside (5 minutes, monthly) — free Checking wheels for debris — free Software updates — automatic, free Battery replacement (every 3-5 years): $100-$250 depending on model Winter storage — bring indoors, charge to 50%, done Total Annual Cost by Model Model Price Annual Running Cost 5-Year Total Segway Navimow i105N $799 ~$47 ~$1,034 Mammotion YUKA 2000 $999 ~$68 ~$1,339 ECOVACS GOAT G1 $1,299 ~$68 ~$1,639 Segway Navimow i108E $1,299 ~$58 ~$1,589 Mammotion LUBA 2 AWD $1,999 ~$79 ~$2,394 Husqvarna 450X EPOS $3,499 ~$75 ~$3,874 Even the most expensive mower to run costs under $80/year — less than a single visit from most lawn services. What About Repairs? Most robotic mowers come with 2-year warranties. Within warranty, repairs are typically free. After warranty, common repairs include wheel motor replacement ($50-$150) and charging station issues ($30-$100). Major failures are rare — these machines have few moving parts compared to gas mowers. Bottom Line A robotic mower costs $40-$80/year to run — electricity, blades, and basic upkeep. Over 5 years, even the premium models cost less than a single year of lawn service. The low operating cost is one of the strongest arguments for going robotic.
