The vacuum cleaner corresponds to the announcement. I used almost daily for 1 month, it sucks very well! it is not heavy nor too noisy compared to my old vacuum cleaner with bag! It empties easily. After vacuuming, there is not funny smells in the air. To capture the allergens side, I do not know how to check! I have a little trouble with the double brush position to switch from carpet to hard floor but hey it's not too a fault. I wanted the DC52 at fair basis because I did not clean filter but the filter is very accessible even my 3 year old daughter gets to remove it! Basically I am very happy with my new vacuum cleaner is really night and day compared to my old vacuum cleaner. I recommend it to everyone!
