This was the first Dyson vacuum that I have purchased. I am completely satisfied with it.  The Omni-glide works great on my travertine floors.  When looking at my floors, they look clean, but then I go over the floor with the Omni-glide and there is a lot of fine dust that is picked up into the dust canister. It is very light weight which makes it easy to maneuver around furniture. When emptying the dust canister, I usually have to pull some of the wands of dust from the canister but this is no big deal. I empty the canister after every use even though there is not much in it.  The Omni-glide is very easy to clean.
