Your carpet may undergo ‘molting’ at some time in its life due to the way in which the fibres are constructed during manufacture. Short lengths of fibre are spun together to form the yarn that makes up the bulk of your carpet, and these fibres can become loose over time after regular vacuuming or cleaning. We would recommend the use of an upright vacuum to avoid excessive molting, but we must stress it is not possible to ‘over-vacuum’ your carpet.
