I have one at home and one at work for years! Do not replace the vacuum cleaner but 1 / complete because the fact of the areas (in bed or furniture) or that does not hurt normal aspi; 2 / allow space the passages of the aspi! Great! Report utility / price unbeatable (especially since I do not change wipe each time, but I dusted with fingers to reuse the same wipe many times!)! Highly recommended ...
