turbo brush is junk, it spins so slowly i can touch it with my pinky and stop it from moving, and as far as the suction with it, horrible as well, as the wider the nozzle gets the less suction overall, not to mention that the brush relys on suction to move so ... plus you cant use both at the same time, its either spinning brush OR suction. But for what its worth the standard 3 inch nozzle works great. Id never use this on home carpets, because of how much water it leaves behind, but for an automotive solution, which was my original intention anyway, its a great little tool.
