Motor not going turbo

I started cleaning, and when it started vacuuming, I heard something strange. It never went into turbo mode; the sound is weak and like there's something inside it. I've already given it a complete cleaning. I've already done a complete cleaning of all the accessories, I've done a factory reset and nothing...
