But it's dumb as a post. As a software engineer I've observed the search and clean algorithms of the BV-85 for 6 years and the D10 is FAR worse.
1. The most attractive feature of the D10 is the ability to declare No Go zones, which work as advertised once you let it do a full house cleaning to generate the lidar map of the house. Note, however, that you need to take a board or something with you and follow the D10 around the house while it does that first cleaning to block it from getting stuck in the No Go zones it doesn't yet know about.
2. The second most attractive feature is the ability to do single room cleaning. Here is fails miserably. If you look at my house map the D10 docking station is at the top left in the TV Room. When I asked it to clean only the Kitchen (at the bottom), the Dining Room (just above the Kitchen) or the Master Bedroom (top right), in all 3 cases the D10 got hopelessly lost in the TV room navigating into one dead end corner of the room or another. In fairness, i had told it that if it couldn't find a matching map to Continue Cleaning. But if that's the case how did it "think" it could find these rooms if it didn't find a matching map? It went nowhere near the door of the room in all 3 cases and never declared "I can't find a matching map". And yet if I asked it to clean the TV room itself or the Living Room (dead center), THOSE worked fine.
3. When navigating the D10 has a large tendency to do random turns (sometimes twice all the way around) and rarely navigates in a straight line when traveling to or returning from a room. When navigating to a remote room it rarely takes the straightest path and often follows a circuitous route (under the sofa and around a chair and THEN to the remote room). That's a sign of poor software design. See attached video.
4. The D10 has a lidar sensor up top and a side proximity sensor, but it seems to ignore them much of the time. When turning a corner and trying to find the new wall it is awful at doing so - FAR worse than the BV-85, which would usually find the wall on the first try without bumping into the wall. The D10, however, seems to ignore its sensors and bumps into the wall 3-4 times before really finding the wall. When navigating it often approaches a wall at a 45 degree angle and bumps into it, despite having a map and despite having lidar.
5. Sometimes when trying to find a doorway it is completely incompetent and keeps bumping into the wall again and again and again. See attached video.
6. Tech Support was not helpful at all, other than to tell me that the docking station had to have 3 feet of total clearance around it and nothing within 10-15 feet is allowed to have moved since the map was generated. I have no such place in my house. And if I did I wouldn't put a D10 sticking out like a sore thumb there. I want it docked out of the way and mostly out of sight.
I returned the D10 after weeks of trying to get it to work as advertised. It was just too much effort and never did succeed at single room cleaning. It's sad - I had been a huge Neato fan but now I'm going to buy anything BUT Neato.
