I just purchased a TAPO RV30 Max Plus vacuum.  Overall I really love it. it does an amazing job cleaning.

I don't get the concept of 3+1 maps for use in a 4 floor house. 

I can save 3 maps and they work fine. I can create a 4th map but can't save it. 

If i make any modifications or do anything other than a full clean on the floors with the saved maps, I lose the 4th map.

Has anyone figured out how to not lose the 4th map or have a workaround for a 4 story house?

Is TAPO planning to add the capability to store a 4th map in a future update?

I'm a somewhat disappointed because the TAPO marketing literature clearly states "4× Multi-Floor Maps"
