STYTJ02YM
"Xiami Mi Robot Vacum Mop-P"
It seems to be the international version of the STYJ02YM, current firmware says up-to-date at v .17, which is not that great, but it's stable. (no multi-floor until v .43 or something, China is over .50 in the china mainland firmware...since MONTHS.) DNS overwrite to get a decent firmware does not work.
