The Philips Sonicare HydroClean works in the same way as the other Sonicare toothbrushes; 31,000 brush strokes per minute drive water and toothpaste over and between the teeth to remove plaque and bacteria.
The HydroClean uses a specialised brush head with HydroClean fins to clean along the gumline and in between teeth. It has a long neck to reach hard to clean places.
Features include a Smart Timer to ensure two minutes of brushing time, a Quad Pacer to ensure a whole mouth clean, and recharge indicator. A charger is included with the toothbrush.
