Vacuum Cleaner Belt Information

By Kent Wallman


The belts for most vacuum cleaners can come in many styles different and hundreds of different sizes. Most the time, vacuums use a belt to propel the agitation mechanism, which is also become to be known as a brush roller accessory. With limited exceptions, many vacuums will use either a flat drive belt, round drive belt, or a geared style drive belt.

The type of belt that your vacuum must use is a very important thing, not only for durability sake, but performance sake as well. The under lying condition and type of belt your vacuum must use to operate will have a massive amount of impact on the machines ability to clean your carpet. The proper way it uses the agitation is considered nearly 70% of the cleaning ability of the vacuum cleaner.

Suction is also very important. The suction is what pulls the dirt that is removed from the carpet into the collection area of the vacuum. The suction, or airflow, is the key when cleaning hard surfaces or when using attachments. Without suction, a vacuum cleaner could only bring more dirt to the surface of carpet. Even though both agitation and suction are important with vacuuming, the agitation is what actually cleans them.

Almost all types of manufacturers use a brush roller device that are made usually of wood, metal, or even plastic parts that are driven by a suction device or brushing motor through the use of three or four different types of belts - round, geared, or flat vacuum belts.

The round belts are the earliest type as they were easy to produce and easy to engineer. The round style, unfortunately, is normally run in the same space as vacuumed dirt. What this means, is that almost all of the dirt, staples, and hair you vacuum up will pass around the belt; cutting, nicking, or even scratching it along the way.

Vacuum cleaner belts have to stretch quite a long way, placing even more stress on the roller and the motor bearings. The round belt is still common, and used even today.

The flat style of vacuum belts are mostly run in a circular fashion, not like the twisted route the round belt goes through to deliver the high quality performance in the appropriate direction you want.

The style allows production of these vacuums to run the belt off of one side of the machine and one side of the brush roller mechanism, instead of the center where all of the dirt is flying by. This is really a good innovation, as you it eliminates premature wear and tear causing failure due to the soiled and filthy belt path.

The latest belt being designed is considered to be the highest quality in the vacuum cleaner industry. Even though there are variations of this model out there, the geared belt drive is the efficient means to turn a brush. The geared belt is sometimes known as a positive brush system all because the energy flow of the brush motor is transmitted fast and directly to the brush roller.

Both the brush and the motor are firmly locked by a bunch of fixed teeth which are attached to each other through a gear cogged belt system unit used without tension. The resulting direct model connection results in higher more effective advanced cleaning because the brush will drive a fast speed even if it is old and ready to break on you.

The flat belt style can stretch and pull as they become warmed up, which will cause the belt to lose its tension immediately when the start button is pushed. When you use your vacuum cleaner, the belt always is going to stretch no matter what you try to do to stop it. Believe it or not, it can lose it's tension the second you put it up to its rest in your storage box.

There is although, one real disadvantage to geared belts - the high cost of the vacuum. Geared belts are usually used on dual motor vacuums. Not do these require the use of a separate suction and brush motor, but it also requires electronic sensory systems to tell you when something is broken or badly wrong with the brush.
