all is said in the title. To be ordered honete before, my wife and I were worried when the sound level. This is WRONG !!!!!! The apirateur (posted 84 dB) in fact that 76 dB, which is the normal noise of a vacuum cleaner !!!!! By cons, with the turbo brush, the noise rises to 84 dB. Note that the turbo brush is dedicated to carpets, thick fabrics, carpets, etc ...... BUT: my wife does not use it as the standard configuration with the normal brush is extroaidinaire even without the turbo brush on these surfaces difficult. We have a long-haired dog, and each time all hair, even those prices carpets and carpet cover or sounds aspirated in 1 single pass. I recommend this vacuum cleaner and even wonder if we should not have just ordered DC32C which is the Meeme but without the turbo brush and sold cheaper on amazon. When allergies. since that vacuum, my wife has no allergy or crisis.
