On the S50 (S5)
if it has recorded the map of let's say the groudlevel floor,
then I uncheck the option Map Save Mode
let it clean on another floor
then put it back on the groundfloor (where it recorded the map)
put Map Save Mode on,
does it still have the map it saved ?
If you uncheck map-saving mode, the last map will be gone also, so you still cannot use the last map. We are sorry S5 doesn't support multi-map saving yet, nor can you choose to save a specific map, we will forward your advice to our developing department and hope they will add this feature in the future.
