Vacuum cleaners, also called a vacuum cleaner or a hopper, is a large mechanical device which causes intense suction to draw dirt and debris out of the floors, furniture, drapery, upholstery and other similar surfaces. It is normally equipped with brushes or paddles which are used to scrub, lift and drain dirt and debris from the device. It is usually electrically powered. The brushes or paddles have a rotating action and the motor is usually located outside the home in a ventilated area. Feel free to find more information at 5 best rated vacuum cleaners
In addition to the brushes, the motors of most vacuums also have a HEPA filter, which is an electrostatic charge filter designed to trap particles which may be harmful if inhaled. Many people suffer from allergies, which include the common cold, although sinus infections and other respiratory problems can cause people to sneeze and cough. These particles often clog the air passageways of the lungs, causing the individual to feel symptoms such as runny nose and eyes, congestion and sore throat. HEPA filters that are installed in many vacuums help to trap these particles before they reach the lungs, therefore reducing the effect on the individual.
A number of newer vacuum cleaners have an adjustable suction level. This feature allows users to vary the strength of the suction generated by the motor. Some are so powerful that they are able to suck up and remove large amounts of dust and dirt from carpets and hard floors. Suction powered vacuums are particularly useful for cleaning upholstered furniture. Many people prefer the motorized variety because they require little maintenance and they do not have to switch the filters often.
