The Braun Series 9 Pro is an electric shaver that comes in various models with different features. According to, the Series 9 Pro+ is an incremental update to the Series 9 Pro, with revised aesthetics and a tweaked slide-out hair trimmer. The cassette is the same 94M that comes with the Series 9 Pro, so no changes there. Some models like the 9590cc include a new accessory, a silicone brush-like ProComfort head that attaches to the shaver. This new massage head is backward compatible with all previous Series 9 models. The S9 Pro+ cleaning station has a silver beveled edge at the top and has an all-matte finish, but it is essentially the same one (Type 5430) that comes with the 93xx and 94xx Pro models. It has 3 cleaning modes and is compatible with the 93xx and 94xx shavers as well (cc or solo). So it’s essentially a Series 9 Pro with some aesthetic tweaks (more black and gold accents) and a new hair trimmer. The Pro models start with 94: 9465cc, 9477cc, 9419s, etc. Compared to the standard Series 9, the Pro models come with a new shaving head (cassette) that should handle longer hairs even better. The shavers also feel a bit more powerful. According to, the Braun Series 9 9370cc Rechargeable Wet & Dry Mens Electric Shaver with Clean & Charge Station is the worlds most efficient electric shaver and features 5 shaving elements to get more hair in one stroke than any other shavers. It also has a Clean & Charge Station. However, it is not clear what materials or ingredients are used in the shaver.
