iRobot Roomba e5 vs iRobot Roomba i7+

The self emptying is key. I only have to replace the bag every 3 months instead of dumping the vacuumed junk into the garbage.

Unfortunately, the map will have to be generated again (third time) but he assures me it will be a much smoother process this time. If so, I expect to give it 4 stars. It's not getting 5 stars until I can more easily generate a map and they can allow indefinite (or at least 24 hour) job delays so I can suspend cleaning overnight and have it pick up where it left off the next. So far cleaning has been adequate but could be better; I assume the "better" would come from the S9 with its greater suction

I would characterize Emily as moderately loud - it'd be annoying to do a phone call or watch a movie while she's running, but having a conversation in the same room is no problem, and my cat doesn't seem overly bothered by her. She does get louder on hard floors than on carpet. Overall, if you're expecting a smart robot that will strategically clean your entire home and then go back to its base in a logical fashion, this is NOT the robot you want. Emily supports one scheduled start on each day of the week, so she's actually doubling as my alarm clock, which is a fun bonus

1. It is very loud when cleaning. As both my wife and I work from home I quickly learned that it can not be run during the day because it is just too loud and distracting. I also found that I couldn't run it in the evenings as it made TV watching unbearable
