Bests & Worsts Reviews from Amazon

I had high hopes for this robot, considering I thought I was buying the top-of-the-line unit from the company best known for robot vacuums. I've had a Neato since 2012 - so I was excited to finally "upgrade" to the industry leader. Turns out, in a majority of instances, this robot won't be able to complete a simple vacuuming job on it's own, without some intervention from me. Looking at the history of job's in the app, I've counted that over the last 3 months, the success rate of the vacuum starting, cleaning, and returning to charge is about 40%. Which i think is unacceptable for such a costly unit, and poorer than my 6-year old Neato. The most frequent reasons this Roomba won't complete it's jobs are: 1) It won't start because it indicates it's bin is full. Except, the bin is actually empty. Apparently there's a known issue where the dust sensors on the robot get clouded with, um, dust - and therefore *think* the bin is full but it's actually empty. There's a work-around that iRobot puts on it's support forums which involves cleaning sensors on the bin and the robot quite frequently in order for the machine to work. But needed to worry about work-arounds is unacceptable on a brand new, supposedly latest tech vacuum. My 6-year old Neato wins on this one. 2) It'll get stuck in random places - even on an open floor. Not on any objects or barriers - it just get's trapped into some corner or chair and won't be able to figure out how to get out. And there's no consistent pattern to where it'll get stuck, so I can't even use a wall barrier to limit the Roomba's path (not that the wall barrier works well either!). Again, my 6-year old Neato does a better job on this. 3) Probably most frustratingly, it will complete its vacuuming job - but won't be able to return to it's dock to charge. See attached video. It sees the dock, moves toward it, but can't latch on and charge itself. And it'll keep trying until the battery completely drains. As a result, whenever I really need to quickly start the vacuum, it's sitting there - pretty and dead. My 6-year old Neato has almost never missed docking itself! Quite honestly, there's more hype than substance with Roombas. My house as two levels, and for the second level I have bought a Neato Botvac D3 Wifi Connected. It has practically all the features (incl. wifi / maps etc.) that this Roomba has, but for half the price and twice the performance. I really regret buying this Roomba and wish I could return it for a refund.
