This information is about vacuum cleaners, but it is accurate for any piece of equipment what uses an electric motor.
You see vacuum cleaners marketed as using twelve amp motors. The fact is, this only means that the motor uses twelve amps of electricity. This amperage measurement does not advise you if the motor is of high quality or not. This doesn't tell you if the motor is durable, has lots of suction, or moves quite a lot of air.
Your home is wired to accept a twelve amp piece of equipment. So the most "electricity hungry" appliances use that amount of electricity. Toasters, hair dryers, and heaters all use this much electricity. Measuring amps in a vacuum cleaner is like measuring milage in a car. The milage doesn't tell you about the quality of the car, or its performance. It only tells you how much gas the motor needs to run.
Suction is about how vigorously the motor can take out air from a space. Canister vacuum cleaners generally have more suction than upright vacuums, because the motors are designed differently. Most upright motors are designed to move air rapidly. The more expensive the airflow, the more expensive the vacuum picks up the dirt. The more suction the vacuum has, the more weight it will pull if you seal the end of the nozzle.
Have you ever seen a vacuum cleaner pick up a bowling ball? It displays great suction, but no airflow. The airflow is what picks up the dirt.
And at sea level, air pressure is fifteen pounds per square inch. As suction is just a matter of reducing the amount of air in a space, the amount of suction a vacuum cleaner has is severely limited. No vacuum cleaner ever made could have more suction that fifteen ponds per square inch.
But the speed of the air? That can be amplified based on the area the air is traveling through, and the air pressure behind it. Airflow has no real upper limit.
To provide an example, a vacuum cleaner that has airflow of one hundred gallons of air per minute is going to do a brilliant job of moving the dirt off of your carpet, and into the bag or canister.
But the quantity of amps? It doesn't render to efficient airflow. The amount of suction? It also doesn't translate to airflow.
When shopping around for a vacuum, ask about the airflow velocity and volume. That will tell you whether the vacuum cleaner will clean or not.
I hope this helps.
