Want to see your electric broom power consumption? Enter your wattage, how many hours a day you run it and what you pay per kWh as your electricity rate, then hit Calculate to get the monthly cost and kWh used on your bill. Those same results also cover electric broom electricity consumption.
Wondering how much power your electric broom electricity consumption adds to the household bill? The short answer is very little: a typical cordless model draws only a few kWh a year, a fraction of what a corded vacuum cleaner uses for the same everyday cleaning of hardwood and tile. Below you will see how to work out the figure from the battery label, what it costs, and how it compares with other floor tools.
An electric broom is a lightweight, battery-driven floor sweeper: a small motor spins a brush that pushes crumbs, dirt and pet hair into a bin. Because it is cordless, it does not draw power while you sweep. It draws power only while the charger refills the battery afterwards, so the energy consumption you pay for is the energy that goes into the battery, plus the small loss in the charger.
Electricity is billed in kilowatt-hours. One kilowatt hour is 1,000 watts running for one hour, and your electricity rate is the price of each one. Wattage alone tells you how fast an appliance uses power, while the time it runs tells you how much it uses in total.
For a battery-powered tool, start from the capacity printed on the pack and divide by the charger efficiency:
$$E_{\text{wall}} = \frac{V \times Ah}{\eta}$$Then turn it into a yearly figure and a bill:
$$\text{kWh per year} = \frac{E_{\text{wall}} \times \text{charges per week} \times 52}{1000} \qquad \text{Cost} = \text{kWh} \times \text{price}$$For a mains-powered tool, such as a corded vacuum, the maths is simpler: watts multiplied by hours of use, divided by 1,000.
Here is a complete example with made-up but realistic numbers. A cordless electric broom carries a 14.4 V, 2.0 Ah pack, which stores 28.8 Wh. With a charger that is 85 percent efficient, a full recharge pulls 28.8 ÷ 0.85 = 33.88 Wh from the wall. The pack lasts about 28 minutes on hard floors, so the average power consumption while sweeping is 28.8 Wh ÷ 0.467 h ≈ 61.7 W. You can also check how many watts does an electric can opener use.
Say you recharge it three times a week. Over a year that is 33.88 Wh × 3 × 52 ÷ 1,000 = 5.29 kWh. At an electricity price of $0.1437 per kWh, the cost per year comes to just $0.76, or about half a cent for each charge.
One charge costs 0.03388 kWh × $0.1437 ≈ $0.0049. If you want a cost per hour of sweeping, divide by the 0.467 hours the battery lasts: roughly one cent per hour of active use, and that is a pessimistic figure because it includes charger losses.
To see where the broom sits, take the same $0.1437 rate and compare four common floor tools. The corded vacuum cleaner is rated at 1,150 W and used 15 minutes, four times a week. The stick vacuum draws 190 W for 20 minutes, three times a week. The robot vacuum recharges a 52 Wh battery after a daily run, again with an 85 percent efficient dock.
| Floor tool | Energy per session (Wh) | kWh per year | Cost per year |
|---|---|---|---|
| Cordless electric broom | 33.88 | 5.29 | $0.76 |
| Cordless stick vacuum | 63.33 | 9.88 | $1.42 |
| Robot vacuum (charging) | 61.18 | 22.27 | $3.20 |
| Corded vacuum | 287.50 | 59.80 | $8.59 |
The corded machine uses about eight and a half times the energy of the electric broom for each session, because it runs at high watts even though it is only on for 15 minutes. Robot vacuums use more per year only because they run every day, not because each run is costly.
A vacuum cleaner has to generate strong suction, and suction needs a large motor. A broom skips that job: its brush moves dirt mechanically, so the motor can be small. The same logic explains why suction power and wattage are not the same thing: a high-wattage motor can waste much of its input as heat, while a well-designed small motor delivers useful cleaning with far less electricity.
Several habits and design details move the yearly total up or down, though never by much. Related: humidifier power consumption.
A bigger pack lengthens the battery run time but also takes more energy to refill. A lithium-ion battery is the standard choice because it holds its charge well and keeps efficiency high, and its sealed design is largely maintenance-free. Doubling the capacity to 4.0 Ah would double the run time and the energy per charge, but not the energy per minute of sweeping.
On hard floors such as laminate, tile and hardwood, the brush meets little resistance and the motor draws less current. Carpets add drag, so the same battery empties sooner and you recharge more often. If most of your home is carpeted, expect charging to rise by a third or more.
The charger for the broom wastes some energy as heat, which is already counted in its 5.29 kWh a year, and a plug left in the socket may keep drawing a trickle after the pack is full. Charging only when the pack is low and unplugging the dock afterwards keeps those losses close to zero. Because the broom is also auto-start, there is no standby display to power.
If you are deciding between tools, it helps to know how the main designs differ in average power consumption.
Look for energy labels and power ratings on the box. Some models also advertise power management, which lowers the motor speed on bare floors, and that alone can make an energy-efficient choice out of a strong machine.
Many shoppers assume that higher wattage always means better cleaning. In practice, wattage describes the electrical input, not the result. The performance of a vacuum depends on airflow, brush design and filtration as much as on the motor, so two machines with very different wattage can lift the same amount of dust from a hardwood floor. When you compare models for your home, read the wattage next to the suction rating and the run time, not on its own.
The same applies to a battery tool. A broom that draws 61.7 W while sweeping uses less than a twentieth of the 1,150 W of the corded vacuum cleaner in our table, yet for crumbs, litter and loose dirt on bare boards it finishes the job in seconds. Reach for the vacuum when you need deep suction on rugs; reach for the broom for quick passes.
A robot vacuum trades speed for convenience: it runs on its own schedule, so its yearly electricity use depends on how many days you let it run, not on a high wattage rating. A handheld vacuum works the other way, with a short burst of work from a small motor, which is why a handheld rarely changes a bill by more than a few cents. A second handheld unit for the car or stairs adds almost nothing to your home's total, and a second robot vacuum for another floor roughly doubles the charging figure in the table.
Manufacturers state suction power in pascals or air watts, and these numbers say more about cleaning than motor wattage does. A model with strong suction power at a modest wattage is an efficient design. Check whether the figure is measured at the nozzle, and whether it is quoted for the lowest or the highest setting, because the two can differ widely.
A corded machine pulls its full 1,150 W from the power outlet the whole time it runs, while a cordless broom draws only about 61.7 W from the battery and pulls its 33.88 Wh from the wall later, at a gentle electrical rate while charging. That difference in when and how fast the power flows is why the yearly kWh figures in the table are so far apart.
Because the broom is already cheap, the biggest savings come from what you use for the heavy jobs. A few steps make a measurable difference to your electricity bill:
Cutting the corded vacuum from four sessions to two a week, in our example, saves 29.9 kWh, or $4.30 a year, without changing how clean the floor looks.
Lower consumption is good for the planet too. The broom's 5.29 kWh a year against 59.80 kWh for the corded vacuum is the basis for your carbon footprint saving, and because most households buy power from a mixed grid, the benefit scales with the kWh avoided. Electric brooms are also quieter than a vacuum, which suits pets and picks up pet hair, dust and litter without a roaring motor. A tool you reach for more often leaves the larger machine idle, and that is the real eco-friendly gain. Related: how much electricity does an e-bike charger use.
You can estimate your own figure in under a minute with any calculator or a spreadsheet:
For a plugged-in tool, use hours a day instead: multiply the rated watts by the hours of use, divide by 1,000, and apply your electricity rate in the same way. Your utility statement shows the exact price, which is better than any national average household figure.
No. Our example uses 5.29 kWh over a full year, which is less than a single day of running a typical air conditioner. It is one of the cheapest appliances in the home to operate.
Per session, yes: about $0.005 against $0.041 for the corded vacuum in our table. It will not replace a vacuum on thick carpet, but for daily floor cleaning it wins on cost and noise.
