Pre-vacuuming includes the utilisation and usage of a vacuum cleaner to remove dirt from the pores of the carpet through the means of sucking that dirt out of the surface of the carpet. This extracts out even the smallest of the dirt particles from the fibres of the carpet that have been stuck inside for aeons and you were not able to notice them with your naked eye. Pre-vacuuming is essential, rather crucial because it enables the penetration of the vacuum into porous areas and proceeds with removal of filth that cannot otherwise be removed through anti-gravitation placement of the carpet or when you try to give the carpet a traditional shake. The dust that is sucked as a result of pre-vacuuming, is deposited into a dirt bag that is fitted inside the vacuum machine. This is a highly reliable step and is a preliminary to all the next cleaning steps.
