Upright Carpet Vacuum Cleaners: are used primarily for the regular maintenance of rugs and carpeting. A revolving cylindrical brush across the front underside within the air intake of the vacuum, combs the face yarns of the carpeting while turning in a forward direction.
Certain upright vacuums have a special type of brush, called a beater brush or beater bar. This brush design also combs the face yarns of carpeting, but simultaneously provides a beating or slapping action on the surface of the carpeting. This beating action is achieved by the beater barm which is a polished strip of metal running the length of the brush along the brush bristles. The slapping action of the beater bar on the carpeting loosens the deeply embedded soils from the carpet backing. The soil particles are then held in temporaty suspension to be removed by suction.
If your machine is equipped with a brush height adjustment, it must be properly adjusted to the thickness of the carpeting being vacuumed. An improperly adjusted only a slight forward pull of the vacuum cleaner should be felt while vacuum cleaning. Before storing an upright vacuum cleaner, the brush must be raised to maximum height, in order to prevent the weight of the standing machine from damaging the brush bristles. The brush, is some designs, are driven by the vacuum motor, whereas in others the brush is driven by its own motor separate from the vacuum motor.
In those designs where the brush is driven by the vacuum motor, an “open face fan” style of motor is used. This “open face fan” style allows the air suspended dirt particles to enter the fan blades. The fan blades then blow the soils into an external filter bag made of cloth material which is attached to the exhaust port of the vacuum motor, and suspended by the handle of the vacuum cleaner. For maximum vacuum cleaning efficiency, the filter bag should be emptied frequently. The accumulation of excessive amounts of soil within the filter bag dramatically reduces the efficiency of the vacuum cleaning system by blocking off the exhaust port of the vacuum motors and restricting its airflow.
Disposable paper filter bags which fit inside of the cloth bag are available for some types of vacuum cleaners, in which case the paper filter bags are disposed of when full.
In other designs of upright vacuum cleaners where the brush is driven by its own motor separate from the vacuum motor, an internal filter bag is utilized. With this system, either a reusable cloth filter bag, or a disposable paper filter bag may be used.
A different types of vacuum motor assembly is incorporated with this system and only clean air is allowed to pass through its fan blades. The filter bag, therefore, is on the intage side of the vacuum motor, and also serves as protection to the vacuum motor assembly. Commonly, a secondary air filter is fastened directly to the air intake of the vacuum motor as a further protection.
To the motor assembly. The secondary filter is usually made of a paper filter material, or a foam filter material. The secondary filter must be checked on a regular basis. Paper filters may be discarded, but foam filters may be rinsed clean in water, then thoroughly dried with a towel before reinstalling.
Upright vacuum cleaners have a very high airflow rating and a very low suction rating.
Upright Vacuum Cleaner Pre-Inspection
- Inspect belts for damage.
- Inspect beater bar/brush is clean and free running.
- Inspect filter bag/dirt cup and airway is clean.
- Set vacuum to proper height. (slight forward pull)
- Inspect electrical cord and plug.
- Turn vacuum on to inspect beater bar operation and air flow.
Care for Upright Vacuum Cleaner After Use
- Coil up cord.
- Wipe down vacuum.
- Empty Dirt Cup (Check filter bag change as required)
- Raise Beater Bar/Brush off floor
- Store Properly
