We've been using the MOVA LiDAX Ultra 3000 AWD on our property, which is about an acre, and so far we're really impressed with it. Our yard is probably a little more challenging than most. We have a lot of trees and flower beds to work around, and the back part of our property isn't a nicely manicured, perfectly flat lawn. There are slopes, dips and some pretty rough areas. I was curious to see how a robotic mower would do back there, but the AWD has handled it surprisingly well. It gets through those areas without getting stuck and does a great job working its way around the trees and landscaping. Setting it up and automatically mapping the yard with the app was easier than I expected. Once we had everything mapped, there really wasn't much we needed to do. It's also extremely quiet. There have been times I've looked outside to check on it and realized it was already out there mowing. So far we're very happy with it. It's handled our yard better than I expected and is definitely saving us a lot of time.
