With great inspiration I used the mop for my good 120 square meters and was about the time savings and ease of use just super happy. Problems with the corners I saw rather not so bad. That was so great that I have my now 80-year-old mother, the part also ordered !!! After a quarter of the fun was over: The mop holder no longer held the top and in the complaint it was that could after too many washes in the washing machine before passieren.Man but reworked from the company and a new holder sent. Similarly, I have ordered several spare wiping heads, so I had nothing left in the machine. - Again three months later, the rotation mechanism gave up the ghost! - Reworked, ok! - Now again three months later, the holder shall not be !! Replacement heads for more! Not new, not old, not machine washed or washed several times - no matter how, he does not! Now I'm also fed up and wonder if you intentionally marketed a product that more quickly gives up the ghost as a popeleinfaches wipe ??? !!
