I've bought the ash vacuum cleaner because of the positive Rezesionen and was bitterly disappointed. After half a ash tray of the filter was completely clogged. After tap and shake to dislodge the ash, he then sucked back without force. It was always a big mess that I wanted to save me, because I was hoping for a neat solution of the ash problem. Even the vacuum cleaner is unverhätnismäßig loud. The unit I have returned!
