Yes you can use the premium parquet bare floor brush on the Dart as well, however it is not included with the Dart unlike the Felix so you'd have to buy one separately. The other differences between the Dart and the Felix is that the Felix offers more features the Dart doesn't have like the variable speed controller, the brushroll shuts off when you take the hose out, it has a swivel neck, and the handle can adjust but it is more expensive than the Dart. If you buy the Felix in the black Onyx color, you'd get an extension hose, a turbo brush, a 24" crevice tool along with a adapter that'd fit, and a longer warranty but it is even more expensive than the other two. The only things that I don't personally care about the Felix is the premium parquet bare floor brush and the turbo brush, I know I've used better. I think the Felix is an excellent vacuum, no doubt about it. Is it the best upright on the market? In my opinion, no. Is it also the best upright Sebo has ever sold? I'd say no as well. In my opinion I think the best upright that Sebo has ever sold would be both the 370 Electronic and the 370 Comfort that they discontinued. I liked them more because they were built better, they were cheaper to maintain because the filters were inexpensive to clean and/or replace, they were more maneuverable to use on bare floors, less hair got tangled on the brushroll, and they had more horse power from their twin fan Domel suction motor.
