Product Overview
The Philips Sonicare 4100 Series is a rechargeable sonic electric toothbrush intended for routine oral hygiene. This white configuration is identified by model HX3681/23 and UPC 075020100757. It uses a rechargeable lithium-ion battery and a click-on brush-head system. The toothbrush provides two intensity settings, allowing the user to select between available brushing-power levels.
Built-in timing functions include SmarTimer and QuadPacer, which provide timing guidance during a brushing session. A pressure sensor provides feedback when excessive brushing pressure is detected. The model also supports a BrushSync replacement reminder for monitoring compatible brush-head replacement intervals. Documented operating time is up to approximately 14 days per full charge under specified usage conditions. The package includes a 4100 Series handle, one C2 Optimal Plaque Control brush head, and a charger.
