I never had a Dyson before. Easy to put together. I have never had a loss of suction except when one of my kids sucked up something that a vacuum should never have to suck!
It ALWAYS works, and one of the best parts is that I can go from shag carpet to hardwood and I don't have to manually adjust vacuum height. One of the other unbelievable features is this vacuum's ability to NOT SCATTER anything when I am vacuuming little things on hardwood or tiled floors.
I love, love, love it.
Downside: I have GOT to figure out how to take it apart for a deep cleaning. We have three golden retrievers and the poor vacuum needs to be autoclaved. Hahaha.
Bottom Line: Yes, I would recommend this to a friend
