Overall, it's an OK accessory set. The big floor brush doesn't work as well as the old, worn out, original brush. There's just too much volume (front-to-back depth) and this results in a very weak vacuum effect. The floor brush is not effective at picking up dirt/crumbs at the ends of the brush but only those towards the center. The original floor brush with it's smaller volume picks up along its full width.
Product appeared to be cheaply made
Would have preferred to order just the piece I needed and not all four pieces. The floor brush is not as long as the original that came with the vacuum and therefore takes more time to cover same area. MD NOTES: They are available here http://builtinvacuum.com/accessories/hardfloor.html
