I will vacuum your carpets were necessary. Anything you can not move of the carpet, particularly larger furniture like sofas, armchairs & tables can be moved from one side of the room and back after the carpet they stand on has been cleaned. I will apply a 'pre-spray', and work it into the carpet with a special machine agitator, this is what cleans your carpet. I have a whole array of special products for stain removal and the treatment of problem areas called 'traffic lanes'. The carpet is then rinsed at high pressure, followed by a powerful vacuum to suck the dirt ​out and leave them as dry as can be. Drying times vary depending on the fiber the carpet pile is made of & its depth. Wool takes longer than man-made; so a short pile carpet of man-made fiber can be dry within a couple of hours, but a deep wool one will take much longer. I will give approximate times on acquaintance with the job. There are however a range of accessories that I use, silvered paper squares and polystyrene blocks that make it possible to place furniture on damp carpet with no ill effects.
