Choosing the right kind of vacuum cleaner can be a difficult task. Nowadays technology is so advanced that there are so many different features available. Firstly, you have to decide what type of vacuum cleaner is suitable, a cylinder or upright cleaner. An upright cleaner is generally used for large carpeted areas. A cylinder is ideal for stairs, hard to reach areas and for cleaning a variety of floors, e.g. hard floors.
The dust sucked up by a vacuum cleaner is either collected into a bag or canister. All vacuum cleaners have filters that are used to remove dust particles, mites and pollen. The higher the level of filtration the more efficient the cleaner is. The different types of filters are standard and HEPA. The dust capacity that a general vacuum cleaner can hold is between 2 and 4 litres. Some vacuum cleaners have surface adjusters, these are when a cleaner automatically adjusts to the height / type of surface it is cleaning. This helps to prevent scratching to hard floors and it makes removing dirt from a deep pile carpet much easier. Some vacuum cleaners have instant hose/wand that are handy for reaching the top of the stairs and making stair cleaning easy.
Many vacuum cleaners are designed to do edge-to-edge cleaning, this means that the whole width of the cleaner picks up dirt and gets closer to the edges. In addition, vacuum cleaners come with a number of attachments to enhance cleaning in many situations. These may be tools to pick up pet hair from confined spaces such as stairs & cars, tools for cleaning skirting boards and in between furniture, a dusting nozzle that is used for dislodging dust and cobwebs, an upholstery tool and a turbo brush.
