I bought this after buying a vacuum cleaner CITY studio for my daughter, already convinced by the suction power of this brand; But unfortunately CITY was too small for my 160 m2 of carpet, slate and granite!. Also this model is very convenient stairs. This model is not especially heavy about 6 kg and the noise is quite comparable to other vacuum cleaners, I even found less noisy than the previous Miele (clean air I do not recommend) or Electrolux I had previously. I am now convinced by DYSON. What economy have more bags to buy and is guaranteed for 5 years without charge. It tracks the dust and sheep (I have 2 dogs) like no other. Also on Amazon, the Dyson becomes affordable. I highly recommend these two models according k'usage you need to make.
