Dual brushes are better on tile.

Yes, usually. Tile floors have grout lines and corners where dust and crumbs hide. A single brush tends to just push stuff around, but dual brushes (one soft, one rubber or bristle) actually funnel debris into the suction path. I’ve tested a few on my own kitchen tile, and the difference is noticeable — less sweeping up later. Just make sure you get one with a decent side brush too, or you’ll still be cleaning the edges by hand.

Your tile floors will thank you.
