That although this Dyson model not from Amazon but the Mercury Market, so I paid there by action and percentages only 179.-! At this price I had to slam! Had until now the Dirt Devil M5020 Infinity V8 ..... So nebeneinader lying quite a difference of at least 2 classes! All plastic, in two, but even there there processing differences ... and because of the Dirt Devil is pathetic! The fittings such as power switch, cables, etc are much more professional than when manufactured DD and therefore act more robust! When you turn on the Dyson is 3x faster from 0 to 100 ;-), volume of Dyson pleasant and quieter than the DD. Suction: The Dyson brings a lot of dust and dirt out of the carpet where the DD failed miserably! Although the DD still funzt it comes to waste! Long story short, the only where the DD is really forward, the price is ... more already not! Quality and cleanliness speak clearly for the Dyson!
