Vacuum Cleaner vs Robot Vacuum: Which Costs More to Run? (2026)
A robot vacuum uses about a tenth of the electricity per clean of a corded vacuum, because it runs a small motor from a battery. Its dock draws a few watts around the clock, which over a month roughly equals the robot's own cleaning use. The corded vacuum cleans more thoroughly, especially carpet, so most homes use both.
At the hours shown, Vacuum Cleaner costs about $16.43 per year and Robot Vacuum about $2.96 in United States (average).
| Appliance | Typical watts | Hours / day | Per hour | Per month | Per year |
|---|---|---|---|---|---|
| Vacuum Cleaner | 1,000 W | $0.18 | $1.35 | $16.43 | |
| Robot Vacuum | 30 W | $0.005 | $0.24 | $2.96 |
Edit the hours to match your own use. Costs use the typical wattage of each appliance.
When the vacuum cleaner makes sense
- You have carpets or pets
- You want a deep clean
- You clean once a week rather than daily
When the robot vacuum makes sense
- You want floors kept tidy daily with no effort
- You have mostly hard floors
- You are out during the day
