We have a 15 year old Dyson DC14 All Floors model. It works fine and I would classify it as BIFL. I would consider another Dyson in the future. We only had area rugs (all hardwood in 95% of the house, the other 5% was tile—kitchen and bath) and it worked fine. We have more carpet in our current house a large area rug, and hardwood look tile floors and it still works quite well.
