The yearly cost is really low, almost negligible. The calculations below assume an average cost of $0.22/kWh, 6 mowing months per year in a garden of the max area of each given model. If your Robomow mows a smaller area, the power consumption and cost will be lower than those indicated below.
Expected power consumption and cost in RS models
- RS630 – 34 kWh per month, about $45 per year
- RS622 – 27 kWh per month, about $36 per year
- RS612 – 22 kWh per month, about $29 per year
Expected power consumption in RC models
- RC312 – 18 kWh per month, about $24 per year
- RC308 – 14 kWh per month, about $18.50 per year
- RC304 – 11 kWh per month, about $14.50 per year
Expected power consumption in RX models
- RX20 – 4 kWh per month, about $5.30 per year
- RX12 – 2.5 kWh per month, about $3.30 per year
