We have had cottage Berber carpet laid in study/playroom. Advised it was hard wearing and ideal for high volume traffic. Within six months there are two patches in each room by the doors that have worn to the backing. We have had it looked at by the manufacturer who says its because we hoovered it so they are not responsible - and fitter says hoovering is not a fitting error so they are not responsible either! Argument commencing - please tell me this is absurd as it sounds and that a new carpet should cope with a Hoover!!
