Cheap processing are significantly off heat and making a bunch of noise! It really should be any aware that we have here is a cheap product from China, which can not be compared with the top devices from other manufacturers like AEG or Vorwerk. It also compares a Mercedes with a Dacia. Anyone who keeps this in mind, get a vacuum cleaner that sucks neat for little money, no more and no less. Therefore, from my 4 stars!
