Changing home location

Hi we got the house completely mapped made changes blocked areas loved all the different functions that it has but now we're wondering can we relocate the home position and still use the same map?

I did that and it worked fine.

Moved to another room. Slid it in to charge and started it.

I’m having problem with the switching  between living room carpet and  kitchen floor. The robot Is digging  a lot of dirt from underneath the carpet, repeats the cycle several times and doesn’t clean. Also the carpet is getting a little damaged ……

How do you instruct the D20 unit to remap the area to be cleaned?
