A carpet is an expensive investment, and correct carpet cleaning is a must. Not only does cleaning preserve the appearance, it also prolongs the life of the carpet.
Particles of dirt in the pile act like countless tiny blades, slashing at the fibres of the carpet. Traffic over the carpet exacerbates this process, so regular hoovering is important. The damage that a carpet receives can easily be seen when hoovering, as the fluff mixed with the dirt is the carpet fibres that have become detached.
