Vacuum cleaner
How much electricity does a vacuum cleaner use?
300–1,400 W · 30–60 min/week · $2–$9 per month
Vacuum cleaners vary enormously in power draw, and — importantly — more watts does not always mean more cleaning.
Wattage by type
- Cordless stick: 200–500 W (and only 10–20 minutes runtime)
- Corded canister: 600–1,200 W
- Corded upright: 800–1,400 W
- Robot vacuum: 20–60 W while cleaning, plus charging
Watts vs suction
EU regulations capped corded vacuums at 900 W for years precisely because manufacturers were competing on wattage rather than cleaning performance. Airflow and brush design matter more. A well-designed 600 W machine can out-clean a 1,400 W one with poor airflow.
Robots are the surprise
A robot vacuum draws 20–60 W while moving, and even running daily its annual energy is about 10–25 kWh — a couple of dollars. Running it daily is not the energy problem it feels like.
Does vacuuming heat the room?
Slightly, in a small sense: 1,400 W of electricity in a vacuum ends up as heat and noise in the room, like any resistive load. In winter that is not wasted; in summer, it adds to the cooling load.
Frequently asked questions
How many watts does a vacuum cleaner use?
300–1,400 W. The figure on the rating label is the maximum draw; actual use varies with settings, age and usage pattern.
How much does it cost to run a vacuum cleaner per month?
With the defaults above it comes to the monthly figure shown in the calculator. At 16.5¢/kWh — the US residential average — that is a realistic middle estimate. Your own bill may be 30% lower or higher depending on state.
Is it cheaper to run a vacuum cleaner at night?
Only if your utility offers a time-of-use plan and you avoid the 4pm–9pm peak window. On a flat-rate plan, the time of day makes no difference to the total.
Does the calculator account for real-world duty cycles?
Not automatically — you enter the effective hours yourself. For compressing appliances like refrigerators and AC units, enter the running watts and roughly the proportion of time the compressor is on, which is usually 30–50%.
Will a newer vacuum cleaner actually save money?
Compare the kWh figure in the calculator against an Energy Star model's stated annual use. If the difference is a few hundred kWh a year, the payback on a replacement is usually long; if it is over 500 kWh, it is worth pricing out.
