As air, as air, that the suction without the noise; I can not believe my ears! Even my dog to stop biting the brush, since there is more noise! More seriously, a perfect product, very quiet (if you ask if there is a motor). With large capacity bag that can throw away without ejecting a cloud of dust as is the case with bagless vacuum cleaners (good shot marketing, but 3 to 4 times more expensive, not to mention the "accordion" filters that cost A LOT!). The small retractable brush is permanently on the pipe, very convenient (he was thinking). A beautiful object suitable; we almost forget the cleaning chore (this is a man who speaks ... so ... more so!). Recommended for mini demanding budgets.
