How Much Does It Cost to Run a Robot Vacuum in Nova Scotia? (2026)
A robot vacuum uses 20 to 60 watts of charging power and runs on a battery of 50 to 100 watt-hours. Daily cleaning uses well under 1 kWh a month, though the dock draws a few watts continuously.
A typical robot vacuum (30 W) costs C$0.006 per hour, or about C$0.27 per month at 1.5 hours a day in Nova Scotia. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (20 W) | C$0.004 | C$0.006 | C$0.18 | C$2.19 |
| Typical (30 W) | C$0.006 | C$0.009 | C$0.27 | C$3.29 |
| High (60 W) | C$0.012 | C$0.018 | C$0.54 | C$6.57 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 1.5 h/day ≈ 16 kWh per year.
One day of a robot vacuum (0.72 kWh) is the same electricity as
- 4.0km in an electric car
- 7.2hours of TV
- 16hours of a laptop
- 80hours of an LED bulb
In Nova Scotia, with electricity at C$0.20 per kWh (source: Hydro-Québec 2025 comparison, 2025-04), a typical robot vacuum costs C$0.006 per hour and about C$3.29 per year at 1.5 hours a day. That is about 43% more than the national average for Canada (C$0.19 per month), because electricity in Nova Scotia costs C$0.20 per kWh against C$0.14 nationally. Each C$1.00 of electricity buys roughly 166.7 hours of use.
How to lower the cost of running a robot vacuum
- Schedule fewer runs in rooms that stay clean.
- Keep the dock plugged in. Cycling it wears the battery.
- Empty the bin so the robot does not repeat areas.
In standby it draws about 3 W, which adds roughly 26 kWh (C$5.26) per year if it is never unplugged.
