Verdict: The Philips Sonicare ProtectiveClean 4100 delivers reliable plaque removal with a longer battery life, outperforming the Sensonic in raw cleaning power (31k vs 30k strokes/min per Consumer Reports) and endurance (2 weeks vs 10 days per spec sheet). However, the Waterpik Sensonic Professional adds flossing capability and an extra brushing mode, giving it a feature edge (per Wirecutter). For most users seeking straightforward cleaning, the ProtectiveClean 4100 is the better value, while floss‑integrated users may prefer the Sensonic.
