I, too, have an older model (2016 980). It only gets confused when the layout of the room changes during vacuuming (ie. a door closes, a piece of furniture is moved). There was a brief period when its navigation skills were less than stellar, but eventually I figured out that it just needed new wheels (the rubber tires got worn, wheels started slipping and the robot was unable to compensate for that). The maintenance mentioned in the article is very similar to what I do. Dust bin and filter - daily vacuuming. Front wheel, bottom brushes and side brushes - weekly. Charging contacts and other parts that require disassembly - monthly or less, depending on . The Roomba is a maintenance friendly robot Absolutely! The Roombas are very easy to take apart and spare parts are easily obtained (both original and replicas). And boy is that a good thing, because you will be replacing parts quite often if you run your robot daily. ;)
