How Many Amps Does a Vacuum Cleaner Use?

A vacuum cleaner uses about 8.3 running amps at 120 volts (roughly 1,000 watts). Because it is a motor load, it surges to several times that for a moment at startup. To get your unit's exact draw, divide the nameplate watts by 120: amps = watts / volts. A corded household vacuum draws about 5-12 amps (600-1,440 watts) with a brief motor surge at startup; a typical upright is around 1,000 watts, or roughly 8 amps. UL caps a household vacuum motor at 12 amps, which is 1,440 watts on a 120V outlet, and a 12A vacuum uses most of a 15A circuit, which is why the breaker trips when a space heater or another large load shares the line. It shares a normal 15A or 20A circuit; run it alone on that circuit. The nameplate governs, and higher amps do not automatically mean better suction.

A vacuum cleaner does not need its own breaker; at 8.3 amps it shares a standard 15A or 20A / 120V circuit (NEC 210.23(B)). Just avoid running it at the same moment as another heavy load on the same circuit. Keep the total continuous load under 80% of the breaker.

Divide the wattage on the nameplate by the voltage: amps = watts / volts. A vacuum cleaner at about 1,000 watts on 120V works out to 1,000 / 120 = 8.3 amps. Add a startup surge of several times that for a fraction of a second on the motor. The nameplate always governs over a typical value.

Yes. A Handheld / stick (corded) draws about 4.2 amps, while a High-power (12A UL max) draws about 12 amps. See the table above for the range. The rating on the nameplate is the number to size the circuit to.

Same answer: vacuum is another name for a vacuum cleaner. It draws about 8.3 amps at 120V on a shared 15A or 20A circuit. A corded household vacuum draws about 5-12 amps (600-1,440 watts) with a brief motor surge at startup; a typical upright is around 1,000 watts, or roughly 8 amps. UL caps a household vacuum motor at 12 amps, which is 1,440 watts on a 120V outlet, and a 12A vacuum uses most of a 15A circuit, which is why the breaker trips when a space heater or another large load shares the line. It shares a normal 15A or 20A circuit; run it alone on that circuit. The nameplate governs, and higher amps do not automatically mean better suction.
