I’m afraid I don’t have an answer for that. But I do have a several-year-old Neato XV-11, which I got after my old iRobot Roomba finally gave up the ghost. (It looks like there are newer XV-12 and XV-21 models, but I haven’t been in the market for a while).
I have to admit: this thing is pretty neat(-o). Rather than the old pattern that the Roomba had (randomly bouncing around in circles), the Neato uses laser positioning to build a more structured route around a room, vacuuming in neat rows across the room, doing one room at a time. It’s a decently functional vacuum that can be scheduled to run daily and operate mostly autonomously, returning to its base when done – like pretty much any other robot vacuum cleaner on the market. But, despite what the manufacturers would have you believe, I don’t find the scheduling feature all that effective because I’ve gotten about a 50% “success rate” of the vacuum (either Neato or the older Roomba) actually finishing a job and getting back to base. The rest of the times I’d come home to find it “crying” somewhere about being stuck, and it’d require a little kick to put it back in action.
I won’t dwell on doing a full review here; there are plenty of reviews out there – Gizmodo did one a couple of years ago (my favorite comment: “F-bombs in a vacuum cleaner article – necessary?“), and more recently there was this Neato vs Roomba Suction Shoot-out showing the Neato sucked way better (!):
If you’re trying to automate as much as you can you should consider adding a robot vacuum cleaner to your arsenal, but keep in mind that it likely won’t replace a full-sized vacuum cleaner for heavier duty (I’m partial to the Dyson vacuum cleaner for those needs).
