Oral-B iO Series 9 in Black Onyx, featuring a 3D dynamic cleaning system powered by AI technology. - Brand: Oral-B - Model Name: iO Series 9 - Color: Black Onyx - Features: AI technology, 3D dynamic cleaning system - Included: Charging stand, brush heads Thank you for looking. I bought this a year ago but barely used it, and it's been sitting in the bathroom. There's water stain buildup under the stand, so it will need to be scrubbed with something like a Magic Eraser. Two brush heads are included.
