Leisetreter with bang

Stand before deciding expensive or cheap - Bosch proSilence Pro with 71 dB or 77 dB with the Siemens - and decided to try it times with the bag vacuum cleaner.
Suction is identical with the right new Dyson my parents.
However, much more impressive is the minimum noise level. At max. Suction can still normally entertain in the room. For daily use should be loose satisfy the average suction power setting. Then you can entertain very quiet even.
More Silence I do not need.
