The Philips Sonicare DiamondClean 9000 is the brand's most elegant sonic electric toothbrush, offering Sonicare's best whitening performance alongside powerful plaque removal. This Costco 2-pack includes two DiamondClean 9000 handles, so both members of a household can enjoy premium oral care.
The toothbrush removes up to 10x more plaque than a manual toothbrush using the included C3 Premium Plaque Control brush head, whose soft flexible bristles curve around teeth to deliver 4x more surface contact. Teeth appear visibly whiter in as little as one day. The slim, ergonomic handle features four brushing modes — Clean for daily use, White+ for stain removal, Gum Health for gentle gum care, and Deep Clean+ for a thorough invigorating clean — each available in three intensities (High, Medium, and Low) to suit sensitive mouths.
BrushSync technology automatically detects which brush head is attached and selects the optimal mode and intensity. A built-in pressure sensor vibrates the handle when you press too hard, and a BrushSync Replacement Reminder alerts you when brush heads need changing. Connecting via Bluetooth to the free Sonicare app unlocks personalized Progress Reports and coaching to improve brushing habits over time. The SmarTimer and BrushPacer guide you through a complete two-minute brushing session.
The rechargeable lithium-ion battery delivers up to two weeks of use on a single charge. Each handle ships with a glass charging base and a USB charging travel case. The universal 110–220V power supply makes the travel case compatible worldwide. A 2-year limited warranty is included. Package contains: 2 handles, 2 C3 Premium Plaque Defense brush heads, 2 W2 Optimal White brush heads, 2 glass chargers, 2 charger bases, and 2 USB charging travel cases.
