Z60 and V50

Here is the MOVA Z60 saying goodbye to the MOVA V50. Soon, the MOVA V50 will be moving to its new home on the second floor, so their paths will no longer cross daily. We like them both, but the MOVA Z60 handles the tile floor better on the first level here.

Interesting that it handles the tile floor better? Any thoughts on why? Would you say they are similar in other areas of the home?
