With growing technological advancements, day today house cleaning has also become very advanced. Vacuum cleaners are such devices which are used to clean the dirt and dust from the surfaces.

When you are planning to buy vacuum cleaners, it is important to know certain things about these devices. A vacuum cleaner works with a simple and basic mechanism of suction. For instance, when you suck a drink through a straw, there creates a difference in pressure at the bottom and top of the straw. The drink gets pushed to the top with more pressure at the bottom than top. It is this same mechanism which works in a vacuum cleaner. Though the mechanism is simple, but practically it is more complex to work as an effective cleaner at house.

A basic vacuum cleaner is comprised of six components which are essential. These components include an intake port, exhaust port, fan, electric motor, a porous bag and a housing which contains other components. This device makes use of an air pump which creates a partial vacuum to suck up the dirt and dust from the surface it is targeted at. A filtering system collects this dirt for later disposal.

To get the latest vacuum cleaner which is suitable for your requirements, you need to know about its various configurations. Vacuum cleaners can be Upright Vacuum Cleaners, Canister vacuum cleaners, Wet vacs or wet/dry vacuums, Pneumatic vacs or Pneumatic wet/dry vacuums, Back-pack vacs, Built-in or central vacuum cleaners, Robotic vacuum cleaners, Small hand-held vacuum cleaners and drum vacuum cleaners. Vacuum cleaners are efficient enough to reach those surfaces which are inaccessible otherwise. To make this possible, vacuum cleaners come with various specialized attachments, brushes, tools and extension wards.

To know about the performance of a vacuum cleaner, there are many parameters which need to be considered. These parameters include airflow (in cubic feet per minute), air speed (in miles per hour or meters per second), suction, vacuum or water lift (in inches of water).Suction is the important parameter as more the suction rating, more efficient is the cleaner. A typical vacuum cleaner used for domestic purpose normally has a suction of about negative 20kPa. Almost all the vacuum cleaners use AC power for functioning but few smaller, hand-held vacuum cleaner models run on battery. These are portable, light weight and rechargeable models used for cleaning cars.
