Comes with a pre-filter! I ordered a separate pre-filter as one of the questions said it was not included in the kit. Great product, a bit heavy but worth the price. Strongly built. Still 5 stars after some use. I have a decent amount of Ryobi products (lots of batteries) so runtime isn't an issue. But for those who just have the big 18vs it entails; I get around 40 minutes on low settings and 25 minutes on high settings. The only thing I would have liked would have been a flat suction nozzle as I have all the tiles in my house and don't need a carpet nozzle.
