Vacuuming alone will only remove surface debris. Dirt settles deep into the fibres of the carpet where household vacuums can’t reach. Any grit that gets into your carpets will act like sandpaper and break down the fibres which will shorten your carpets lifespan.
Any food, spillages and general traffic create the perfect environment for bacteria and germs. Any smells from pets, food, smoke or moisture will linger long after the source has been removed, and having your carpets professionally cleaned can eradicate these bad odours.
