Xiaomi NUN4132GL shaver accessory Shaving head

Dual-track foils and twin blades
Two shaves in one
Mi Electric Shaver S500 Replacement Heads feature dual-track foils and a twin blade design, for 50% more intake than a single-track foil shaver, giving you two shaves in one. The inner and outer tracks contain a total of 15 blades that complement each other for a quick shaving experience.

Secondary foil blades lift hairs for the primary foil blades to cut
For a cleaner shave
The foils themselves have a certain thickness, which can cause shorter stubble to be missed. To solve this problem, Mi Electric Shaver S500 Replacement Heads are equipped with a thin 0.08 mm secondary foil blade mounted on top of the outer track of the primary blade. The secondary blade lifts the hairs before the main blade quickly cuts them off, resulting in a cleaner and more thorough shave.

Shaver-heads and foils are made from high-quality imported steel

Electrochemical machining (ECM)
Smooth foils—sharp, wear-resistant blades
The blades and foils are finished using the same electrochemical machining (ECM) technology used for precision medical equipment. This not only reduces the appearance of metal burr but also greatly improves wear resistance. The three sets of blades are flat and fit together seamlessly with the foils.

Assembly and disassembly instructions:Apply pressure to the release port of the shaver head bracket and remove the old head.
