The Mova Z60 offers many great features and the MaxiReach brush, collapsable radar, and threshold crossing are three of the main features available on the Mova Z60. Those three features allow the Mova Z60 to get in tight spaces, hard to reach areas, or get in spots that older robot vacuums could never reach. I think its quite impressive to watch the Z60 navigate by itself, even with an incorrect mapping or new obstacles.
