As mentioned above, beater bars works to lift up the deep soil and dirt that stucks deep inside the carpet. The function of the beater bar is that when beater bar turns at speed and with turning the beater bar vibrates. As far as the beater bar vibrates the carpet loosen its dirt and the suction system would then transfer the dirt to the vacuum storage area. The brush bristles that are attached to the vacuum beater bar actually helps to brush the carpet and clean the dirt.
Basically the design of the rotating brush has changed by making the brushes stiffer, varying lengths of the bristles and thus trying to mimic the action that the original beater bar was doing. The better quality upright version utilizes a drive belt driven by the electric motor of the unit. The brush is fit for doing about 6500 cycles each minute. The brush is normally turned by the electric motor of the unit, or in some case has its’own dedicated motor and drive system.
The main reason for fitting beater bars was to give a more prominent vibration to the carpet in order to release the dirt and then have it brushed and sucked into the storage area. The other reason and function of the beater bar is to loosen any yarns that have been trapped beneath other dirt in the carpet, enabling the cleaner to brush and suck up these yarns.
The beater bars are the most helpful feature in vacuum cleaners. They are actually meant for work better on carpets and for the better cleaning of your carpets so that your carpets look more clean and super fluffy. This super feature is sometimes not useful for your homes. The reason behind this is the beater bars work more efficiently on carpets but not on the floors without carpets. On normal carpets, the beater bar works on it normally as well but some types of carpets are not for the beater bar usage. Sometimes it can damage your carpets so it is better not to vacuum on hard surface floors. If you have pets in your homes, beater bar works efficiently on carpets as they remove all kinds of dirt and pet hair also from the carpets and floors.
For cleaning hard- or laminated floors, we would suggest not using a unit with a beater bar. We would suggest getting a good suction-type cleaner. This type of cleaner would also be preferable for Berber carpets as well as laminated-type of flooring. This would do a good job, keep the floor sparkling clean and not cause any damage. People spend lot of money installing wooden floors, and hardwood can be particularly expensive..
The reason for this is that the cleaners that only use suction do not have the capability to do a deep-clean to remove dirt. The best suggestion would be a cleaner with a beater bar in this case.
