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 $16.74 a year and Robot Vacuum about $3.01 in the US.
