This product is truly awesome! As a secondary device in addition to the vacuum cleaner really highly recommended. Again and again I am amazed at how a machine without electricity and without bags can so easily take up crumbs and hair. We have a relatively high, red velor carpet, which is not really tolerant of dirt. Here falls every hair on - the happier I was that I always move house the carpet sweeper for many years with me ... Even, or just take the cat hair after scuffles the device is perfect.
