From my experience, mostly all vacuums read at 1,000 watts, depending on the actual usage of the vacuum. If it's used over the course of an hour, it becomes 1000 watt-hours / one kilowatt-hour (kWh). There are certain vacuums that convert the normal 1,000 watts to higher watts, for example, if you use a vacuum with a 12 amp, it converts to 1,440 watt-hours or 1.44 (kWh).

Let’s answer the question that comes up with knowing the watt of my vacuum cleaner.
The Watt Of My Vacuum Cleaner
Can having a low wattage affect the suction power of your vacuum cleaner?
Well, the answer might amaze you that more vacuum wattage DOES NOT equal more suction power. I can hear you muttering now, but wait a bit… although retail and local vacuum suppliers have elevated watts as the major determiner of excellent cleaning performance, but don't be cajoled into believing it. Because if you do, you’d probably be taken for a ride… Let me explain why…
Having a vacuum cleaner is good, but how do you know, what you’re using isn’t a dud? What is the actual determiner of the cleaning performance of your vacuum cleaner? The truth is, your wattage does not equal your suction, although most people believe the opposite. The watt of your vacuum cleaner is only a measurement of how much power (electricity) will be consumed when being used. So, basically, a 1,440W vacuum cleaner will only use 1.44hour. To make this understandable, you can see the watt as consumption measurement, and not a power output measurement, so in essence, your wattage does affect your suction power.
Now let’s explain the variables that make up the watt of a vacuum cleaner.
The variables that make up the watt of a vacuum cleaner
Let’s check the most common type of vacuum cleaner – canisters – to see how much power (electricity) they draw from your wall socket.
• The first variable attached to the canister vacuum is the motor-fan
• The motor then spins at high speed (ranging from 9,000 to 28,000) although this depends solely on the motor model; it then creates the airflow that empties the base of your vacuum.
• At the front base, the airflow propels the suction that then picks up the dust, dirt, pet, debris and other dust particles
• Then finally as the air flows through the vacuum it passes through a filter (HEPA) that purifies the air in the canister before emptying the bin.
With all these variables we can now see, why it’s important you know the wattage of your canister vacuum cleaner.
How can you calculate the watt of your canister vacuum cleaner?
One major design factor about vacuum cleaners is that they draw less than 12 amps of power, for them to be utilized effectively in the home. Why is this so? It happens because the average home circuit breaker is normally rated at 15amps or 1800 W.
Although, for the circuit breaker to function safely for a continuous load (for 2 hours or 3 hours), it first limits the circuit breaker to 80% of the maximum load to avoid overheating and potential burns. (80% of 15amps is exactly 12amps).
Now to calculate the watts of a vacuum cleaner, let's paint a scenario so you can grasp the idea here… if we use the equation for finding watts of equipment (Volts (v) x Amperes (I) = Watts (W)) and calculate with 120 volts and 12 amps, this results into 1,440W. It’s advisable you don't run another appliance on the same circuit breaker when running your vacuum cleaner, because it will trip the circuit breaker.
You've got the average vacuum cleaner that won't cost you much energy, yet it's advisable to have a durable one, like a canister vacuum cleaner, so you don't have to spend money on a new vacuum every few years.
As with most motorized equipment in every home, you want more power, but not so much of it, as efficiency is usually better than torque.
