How Many Amps Does a Vacuum Cleaner Use?
Vacuum Cleaner draws about 10 amps at 120 volts (1,200 watts running). At 10 A, a vacuum cleaner fits comfortably on a standard 15 A or 20 A household circuit.
Amps = watts ÷ volts. Enter the wattage from your appliance's nameplate or label for an exact figure.

Breaker figure is guidance for a simple resistive load; confirm against the nameplate and a licensed electrician.
Vacuum Cleaner amperage at 120 V and 240 V
Same 1,200 W load: the current halves when the voltage doubles. Vacuum Cleaner is typically a 120 V appliance in US homes.
| Draw | Watts | Amps at 120 V | Amps at 240 V |
|---|---|---|---|
| Running | 1,200 W | 10 A | 5 A |
Breaker and circuit for a vacuum cleaner
At 10 A, a vacuum cleaner fits comfortably on a standard 15 A or 20 A household circuit. For a dedicated circuit, guidance is a 15 A breaker with 14 AWG copper (75°C terminations).
Guidance only: actual circuit sizing depends on your unit's nameplate, wire run length, and local code. Confirm with a licensed electrician. See the wire & breaker size chart for the full NEC ampacity table.
Measure what a vacuum cleaner actually draws
The figures above are typical ratings. A plug-in power meter between the outlet and the cord shows the real amps and watts with nothing opened up. A clamp meter reads one conductor at a time, so it is the tool for hardwired and 240 V circuits; clamped around a whole cord it reads close to zero.
