How Much Does It Cost to Run a Robot Vacuum in Australia? (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 A$0.010 per hour, or about A$0.47 per month at 1.5 hours a day in Australia. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (20 W) | A$0.007 | A$0.010 | A$0.31 | A$3.83 |
| Typical (30 W) | A$0.010 | A$0.016 | A$0.47 | A$5.75 |
| High (60 W) | A$0.021 | A$0.032 | A$0.94 | A$11.50 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 1.5 h/day ≈ 16 kWh per year.
In Australia, with electricity at A$0.35 per kWh (source: AER Default Market Offer 2026–27, 2026-07), a typical robot vacuum costs A$0.010 per hour and about A$5.75 per year at 1.5 hours a day. Each A$1.00 of electricity buys roughly 95.2 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 (A$9.20) per year if it is never unplugged.
Frequently asked questions
How much does a robot vacuum cost to run?
Around 2 to 4 kWh a month including the dock's standby draw.
