Philips Norelco Shaver Series 9400 Wet and Dry Electric Shaver

Our review of the Philips Norelco Shaver Series 9400 finds it best for men who want a reliably close, comfortable shave with modern sensors and a forgiving head design. The standout reason to consider this shaver is its SenseIQ Smart Hair Sensor combined with the 360-degree flexible heads, which together adapt to beard density and facial contours for a gentle shave that aims to reduce irritation. It works wet or dry, includes a pop-up trimmer for detailing, and gives about 50 minutes of cordless use after a one-hour charge, making it practical for daily or travel use.

Key Features

• SenseIQ Technology: The Smart Hair Sensor reads hair density 250 times per second to adjust cutting performance for an effortless shave across varied beard areas.
• Dual SteelPrecision Blades: Up to 150,000 cutting actions per minute deliver excellent closeness, able to handle even a 5-day beard without multiple passes.
• Nano SkinGlide Coating: A microbead coating on the shaving head helps the shaver glide smoothly over skin to reduce friction and irritation.
• 360 Degree Flexible Heads: Fully flexible heads follow facial contours, improving contact in tricky areas like the neck and upper lip for a more consistent result.
• Wet and Dry Use: Can be used with water, gel, or foam and rinsed under the tap for easier cleaning and a more comfortable wet shave routine.
• Included Accessories: Ships with a travel case, USB-A charging cable, and charging base for convenient portability and charging options.

Who It's For

The Series 9400 is ideal for men with stubble up to a 5-day beard who want a close electric shave while minimizing skin irritation; the combination of flexible heads and Nano SkinGlide coating is aimed at sensitive skin. It also suits travelers and anyone who prefers wet shaves sometimes, since the unit is waterproof and includes a travel case and USB-A charging cable.

Users who need a very low-maintenance grooming tool with single-button simplicity will like this shaver. Those who prefer foil-style shavers or need extremely precise clipping and very short stubble trimming might look elsewhere, as this rotary design emphasizes contour following and closeness rather than foil-style finishes.
