This information roller table motors is concerning vacuum cleaners, but it is true for any appliance what has an electric motor.



You see vacuum cleaners advertised as making use of twelve amp motors. The truth is, this only means that the motor makes use of twelve amps of electricity. This amperage measurement does not tell 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 plenty of air.

Any home is wired to take a twelve amp appliance. So the most "electricity hungry" gadgets 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 powerfully the motor can extract 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 mass it will pull if you seal the end of the nozzle.



Have you ever watched a vacuum cleaner pick up a bowling ball? It reveals great suction, but no airflow. The airflow is what picks up the dirt.

Plus at sea level, air pressure is fifteen pounds per square inch.

Seeing 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 velocity of the air? That can be increased based on the area the air is traveling through, and the air pressure behind it. Airflow has no real high border.



As an example, a vacuum cleaner that has airflow of one hundred gallons of air per minute is going to do a fantastic job of moving the dirt off of your carpet, and into the bag or canister.

But the amount of amps? It doesn't transform to efficient airflow. The amount of suction? It also doesn't translate to airflow.


When shopping for a vacuum, ask about the airflow velocity and volume. This will tell you whether the vacuum will clean or not.



I hope this helps.
