This device is effectively silent, very silent see compared to my previous vacuum. Power is very correct. The most. It's like my old vacuum cleaner of a German manufacturing apparatus, of course, all the accessories of the former are compatible in diameter than those of the new. result in double lengthens rigid tubes and two accessories of the old brand that it did not. Two flaws, but I knew for a ... The wheels are too small, absolutely not facilitate the crossing of the power cord and the second, it is very light, too light, and easily flips on the famous cord. In conclusion the performance is really there, total pleasure in use, no. However, the efficacy / pleasure / price ratio remains largely positive.
