I used one of these today and I was not impressed. While it is a powerful vacuum, it is very bulky and heavy. I was not able to get under the furniture or in the corners as easy as I was expecting. Dyson built in attachments, however, I don't feel it is very user friendly. The attachments are connected to the handle and very difficult to connect. It was heavy to carry as I vacuumed the stairs, making me think that it would be even more difficult for an elderly person to use. I will say that I used the vacuum on all surfaces such as carpet, tile, and hardwood and it was very powerful leaving the floor clean. I also like the fact that the cord is extremely long so it did cut my time in half without having to keep unplugging. I also like the easy clean up and bag less container making it much better for allergies. After using this vacuum today, I feel just as comfortable with my vacuum with the same comparisons but more economical to purchase. My biggest suggestion would be to try it before you invest.
