My predecessor, the Siemens Rapid 2000 has exactly given up the ghost after 2.5 years. The cyclone dust collector I had from the beginning big problems! Appropriately, the part has only plastic tabs that are continuously loaded during emptying and cancel at short notice. The emptying per se: the dust settled not good disposed of in the trash can - partially the dust was denser than before the action. The collection container is blocked permanently fast, later does not hold tight and the engine blows. The system is not even begin to mature! He was also very loud. Steer clear of this scrap - have, lowered, paid - it ägert me today, that I, for the model 99! Returning I could not it unfortunately. The collecting container does not belong to the parts that are replaced on warranty! Leave it dear and buy a Dyson equal!
