Head mount: Xiaomi / Mijia S300-S500 rotary 3-blade¶
Provenance: Manufacturer claim
Status: unmeasured
Xiaomi / Mijia rotary 3-blade head module shared across the S300, S500,
and S500C bodies, per the Xiaomi official accessory page that names all
three devices in the product title. Aftermarket sellers on JD and other
Chinese marketplaces group the legacy MJTXD01SKS device code into the
same listing family ("S300 / S500 / MJTXD01SKS 通用机头"); that
cross-fit is marketplace-claim only and is the single biggest physical
test target for Batch A. JD aftermarket vocabulary uses 内5角 /
五角形转轴口 ("five-sided drive-socket / shaft-mouth") to describe a
drive interface; Soocas / Xiaomi shared patent IP also references a
five-sided shaft matching structure across this family and adjacent
Soocas / Xiaomi models. Treat the five-sided shaft feature as a
measurement target, not as a published geometry claim.
Notes¶
Xiaomi / Mijia S300 rotary three-blade shaver. Buyer-facing fitment
vocabulary keys on the body code, and the Xiaomi official accessory
page lists S300, S500, and S500C as compatible with one shared
replacement head. Aftermarket JD listings also group MJTXD01SKS
into this listing family; that cross-fit is marketplace-claim only.
Charging, wet/dry, and release year fields are best-effort from launch
coverage and the Xiaomi store page, not measured by the project.
