When I got this, I was concerned about the height difference between the Z60 and the P10 Pro Ultra. One of my favorite things about the P10 was that it cleans underneath my couch and furniture. Looking at the pics of the Z60, I could tell it was a little thicker than the P10, but I wasn't sure how much, so I thought I'd help some of you out that have the same concern. I didn't realize how much of a game changer fitting underneath furniture was until I owned a robot that could do it. I had a Roborock Saros 10R for a while and it was a super low-profile machine that fit everywhere. It didn't last due to other reasons, but it opened my eyes to how much I enjoy having the entire floor cleaned, not just around furniture. The P10 has been great at this as well, but it was a feature I didn't want to lose in this "upgrade". I'm happy to say that I haven't!! When the Z60 lowers it's radar, it's actually a little lower overall in height than the P10!!!
