I use many of these accessories. The "soft brush has soft bristles for cleaning delicate surfaces and objects" for example to trap the dust on top of the books on the shelves, ... it is flat enough to go where the flexible accessory sold with the vacuum can not go, but also on clothing, coats, jackets, coming out of plaquard ... The "stiff brush with stiff bristles for easy cleaning dust resistant" on rugs, indispensable. The "brush surface height that rotates at different angles to clean hard to reach areas in height," I use it everywhere from the moment when the surface is not at ground level. What I can blame the latter is that it is so articulate in every way, I'm struggling to hold it in the desired position, it should be maintained with the other hand. All accessories snap easily, allowing them to change as and when the meeting objects to dust. I have a wonderful 26 Dyson (with turbo brush + Carbon in soils of all flat brush fibers), and more with this kit, it is the class! I'm in the home storage, and more, in full revolution in available in the rooms, this vacuum cleaner I love it!
