The Dyson DC 44 has a trigger that must be held down with your finger the entire time you are vacuuming. In my opinion, this is not a good feature and should be written on the outside of the box. I would not have bought the vacuum if I had known that before I decided to buy it. Also, the rechargeable battery doesn't hold the charge after about a year of use. Due to this situation, I would never buy another expensive Dyson. Any of the other brands I have had in the past are as good or better than the Dyson and you could buy 4 of them instead of one Dyson.
