2 - Economy: 9/10
it is a 1100 watts that sucks as 2200 watts, the power saving calculation is quickly made.
3 - the silence: 6/10
Seriously ... Certainly the pocket without vacuums are very noisy (some with vacuum Dyson models eg you can go and make you do audiometry, so they are noisy). But 62 db, it's still noisy ... we would be around 55/58 dB (I recall that every 3dB, dual noise). That's fine, but if you go up some accessories such as brush, already the sound of it is sufficiently strong for it is the power of the air that drives on its axis, so it hisses like a blackbird seeking cherries. Compared to the majority of vacuum cleaners that I had in hand, it is true that it is slightly quieter. However, I do not like at all the video advertising that we believe do not wake the sleeping animal passing just next to it with the vacuum cleaner (if that is the case, you have to take Emergency animals also spend an audiometry, because he is deaf). This is called false advertising because too exaggerated. So a better, but not "the best".
4 - Accessories: 8/10
I like the integration of some accessories in the handle. That's a plus.
The handle is long enough to pass under furniture. All pivots on the brush chosen to facilitate its passage under the furniture ... so very well. The ergonomic handle does not displease me at home that some criticism.
5 - Use: 9/10
It is powerful and that's good, adjustable vacuum / suction so tutto bene. The equivalent figures Power: 2200 watts and Depression: 32 kPa (the minimum being 31 with such power, allows an honorable performance How many buyers do not associate these two key figures for choosing a vacuum cleaner !!. !). So there they can be alone.
Conclusion: 8/10 - a good score makes me recommend it if you can raise a little more than 5 kg when carrying it.
