Understanding Vacuum Cleaner Specifications
Understanding vacuum cleaner specifications is one of the most challenging aspects of selecting a new vacuum cleaner. First and foremost, consumers want vacuum cleaners that offer the best cleaning ability. And most consumers typically equate cleaning ability with "power" or "suction".
Cleaning ability is not just about vacuum suction power, even though this is an important element of vacuum cleaner performance. With a little information and education, you will be able to sift through the numbers and better understand what the specifications mean and which ones are important to you.
Unfortunately, there is no single rating that indicates cleaning ability. However, there are a number of primary vacuum cleaner specifications, that when clearly understood, allow consumers to make educated decisions concerning which vacuum cleaner will have the best cleaning ability.
These primary specifications include watts, amps, volts, water lift (or sealed suction), horsepower, air watts, and airflow.
There are also a number of other, secondary specifications that influence cleaning ability that we'll also examine. These include filtration, cleaning tools (agitation), capacity, quality, noise, features and cost.
In order to make sense of all this we first need to understand the basics of how a vacuum cleaner works.
All vacuum cleaners operate based on air flowing from the opening at the cleaning head or tool, through the vacuum cleaner and the bag and/or filter system and then out the exhaust port. This airflow is created by the vacuum motor, which also may be referred to as the suction motor.
The vacuum motor consists of electrical components attached to a fan or multiple fans. When the fans spin, a partial vacuum is created and the pressure inside the vacuum cleaner drops below the ambient (or existing) air pressure in the room. Because air pressure is higher outside the vacuum cleaner than inside, air rushes through the vacuum cleaner.
So, it is easy to see that the vacuum motor is the heart of a vacuum cleaner. After all, the more powerful the motor, the greater the pressure differential and therefore the more vacuum suction power and airflow, right? And it is for this reason that most of the specifications you see concerning cleaning ability relate either directly or indirectly to the motor.
But here's where it gets tricky. Specifications for components such as the motor do not necessarily relate to the performance of the entire vacuum cleaner, and therefore are only a part of the story.
Let's take a look at the primary specifications one by one:

Electrostatic discharge should always be avoided around sensitivecomputer components. In some cases, it may be better to remove dust and other foreign matterby applying a blowing force rather than vacuuming. The bag used in this type of vacuum shouldbe fine enough to collect toner particles. Otherwise, these particles may circulate within andoutside the vacuum and spread toner.Explanation
